4.20 cm² is the area of the triangle STU to the nearest 10th of a square centimeter.
Given, t = 3.4 cm, u = 6.9 cm and ∠S = 21°
We know that the formula for the area of the triangle = 1/2 * t*u *sin(S)
Substituting the values
Area = 1/2 × 3.4 × 6.9 × sin(21°)
Area = 11.73 × sin(21°)
Area = 11.73 × 0.3583
Area = 4.2016
Rounding to the nearest 10th of a square centimeter .
Area = 4.20 cm²
Hence, 4.20 cm² is the area of the triangle STU to the nearest 10th of a square centimeter.

7.) The Goody's store manager charted
the number of coats sold compared
with the outside temperature. What
kind of relationship would you expect
between the variables?
It is also possible that there may not be a clear relationship between the two variables or that there may be other factors that influence the number of coats sold, such as seasonal trends or fashion trends.
What is variable?In mathematics, a variable is a symbol or letter that represents a quantity that can vary or take on different values in a given situation or equation. Variables are commonly denoted by letters such as x, y, z, a, b, c, etc. They are used to represent unknown or changing quantities in mathematical expressions or equations.
For example, in the equation y = 2x + 3, x and y are variables. x represents an unknown value, while y represents the value that results from the equation for a particular value of x. In this case, the variable x can take on different values, and the corresponding value of y will change accordingly.
Variables are used in a wide range of mathematical concepts, such as algebra, calculus, and statistics, to represent and manipulate different quantities and relationships between them.
It is reasonable to expect that there is a negative correlation between the number of coats sold and the outside temperature. In other words, as the temperature gets colder, the number of coats sold would increase, and as the temperature gets warmer, the number of coats sold would decrease. This is because colder temperatures would typically prompt people to buy more coats to stay warm, while warmer temperatures would make people less likely to buy coats. However, it is also possible that there may not be a clear relationship between the two variables or that there may be other factors that influence the number of coats sold, such as seasonal trends or fashion trends.

Which name best describes the polygon with
vertices (0,0), (4,8), (12,8), and (16,0)?
The polygon described by the given vertices is a trapezoid.
Why is the polygon is given vertices a trapezoid?
A trapezoid is a quadrilateral with at least one pair of parallel sides. In this case, the sides with endpoints (0,0) and (16,0) are parallel to each other, and the sides with endpoints (4,8) and (12,8) are parallel to each other. Therefore, the polygon described by the given vertices is a trapezoid.
In addition to having parallel sides, a trapezoid can have various other properties, such as being isosceles (having two equal sides) or having perpendicular diagonals. However, based solely on the given vertices, we can determine that the polygon is a trapezoid.
A trapezoid has various properties, including having one pair of parallel sides, having one pair of non-parallel sides, and having two pairs of adjacent angles that add up to 180 degrees. It can also be isosceles if the non-parallel sides are equal in length.
The trapezoid is a commonly studied shape in geometry because of its simple properties and its appearance in many real-world applications, such as in architecture and engineering. Trapezoids are used in the design of roofs, bridges, and other structures that require stable, load-bearing shapes.

ldentify the relationship between the angles. y : x
Answer:
there both symmetrical
Answer:
Congruent
Step-by-step explanation:
When visualizing how two angles are related, try squashing the two parallel lines into each other. When you do that with these angles, they go from appearing like =\= to appearing like -\-, with x and y being catty-corner from each other.
Because the parallel lines are straight, x and y are both half of a pair that adds up to 180. However, x and y aren't sharing a straight line, so they cannot add up to 180 with each other. That leaves only one possibility, that x and y have the same angle measure.
The outside temperature was 4°C for the next six hours the temperature changed at a mean rate of -0. 8°C per hour for the next two hours what was the final temperature
The final temperature after the next 8 hours (6 hours at -0.8°C per hour, followed by 2 hours at -0.8°C per hour) will be -2.4°C.
The final temperature can be calculated by subtracting the total temperature change from the initial temperature of 4°C.
The total temperature change during the next six hours can be calculated by multiplying the mean rate of -0.8°C per hour by the number of hours, which is 6.
-0.8°C/hour x 6 hours = -4.8°C
Therefore, the temperature after the next six hours will be:
4°C - 4.8°C = -0.8°C
For the next two hours, the temperature changed at a mean rate of -0.8°C per hour. This means the temperature decreased by:
-0.8°C/hour x 2 hours = -1.6°C
So the final temperature will be:
-0.8°C - 1.6°C = -2.4°C.
Therefore, the final temperature after the next 8 hours (6 hours at -0.8°C per hour, followed by 2 hours at -0.8°C per hour) will be -2.4°C.

Determine whether the triangles ar similar. It so, write a similarity statement and name the postulate or theorem you used. If not, explain.
Answer:
Option B.
Step-by-step explanation:
Angle SOB and Angle VOK are vertical angles, and thus congruent because all vertical angles are congruent.
Lines SB and KV are parallel, cut by the transversal SV, and Angle S and Angle V are Alternate Interior Angles. So, Angle S and Angle V are congruent by Alternate Interior Angle congruence.
Therefore, Triangle SOB and Triangle VOK are similar by Angle Angle similarity postulate.
In circle m, secants pamd and pbc are drawn from point p such that mbc = 100 and mcd = 62°. which
of the following is the measure of p?
(1) 19
(2) 22
(3) 34
(4) 40
In the circle, the measure of p is 34 (option 3).
First, we know that angle MBC is an exterior angle to triangle PBC. Therefore, the measure of angle PBC is equal to the sum of angles MBC and MCB, which is 100 + (1/2)(angle MCP) = 100 + (1/2)(angle MQP).
Similarly, angle MCD is an exterior angle to triangle PCD. Therefore, the measure of angle PDC is equal to the sum of angles MCD and MDC, which is 62 + (1/2)(angle MPQ) = 62 + (1/2)(angle MQP).
Since angle PBC and angle PDC are both subtended by the same arc BC, they are equal. Therefore, we can set the expressions for these angles equal to each other and solve for angle MQP:
100 + (1/2)(angle MQP) = 62 + (1/2)(angle MQP)
38 = (1/2)(angle MQP)
angle MQP = 76 degrees
Finally, we can use the fact that angles MPQ and MQP form a linear pair, so they add up to 180 degrees. Therefore, angle MPQ is 180 - 76 = 104 degrees.
Since angle MPQ is an exterior angle to triangle PAB, we can use the exterior angle theorem to find the measure of angle P, as follows:
angle P = angle MPQ + angle PAB = 104 + 100 = 204 degrees
However, angles in a circle cannot be greater than 180 degrees, so we need to subtract 180 from angle P to get the actual measure of angle P:
angle P = 214 - 180 = 34 degrees
Therefore, the answer is option (3).

The areas of two triangles are 50 cm2 and 98 cm2. what is the ratio of their perimeters?
a ) 25/49
b ) 50/98
c ) 625/2401
d ) 5/7
e ) 2500/9604
The ratio of the perimeters is 14/5, which simplifies to 70/25, which reduces to 14/5. So the answer is (d) 5/7.
Let's use the fact that the ratio of the areas of two similar triangles is equal to the square of the ratio of their corresponding side lengths. If we let the corresponding side lengths be a and b, then we have:
(area of first triangle)/(area of second triangle) = (a^2)/(b^2)
We are given that the areas of the two triangles are 50 cm^2 and 98 cm^2, respectively. Let's call the side lengths of the first triangle a1, a2, and a3, and the side lengths of the second triangle b1, b2, and b3. Then we have:
(50)/(98) = (a1a2)/(b1b2)
We don't know the actual values of a1, a2, b1, and b2, but we can find the ratio of their perimeters by adding up the side lengths of each triangle. Let's call the perimeters of the first and second triangles P1 and P2, respectively. Then we have:
P1 = a1 + a2 + a3
P2 = b1 + b2 + b3
Dividing P1 by P2, we get:
P1/P2 = (a1 + a2 + a3)/(b1 + b2 + b3)
We can rewrite the ratios of the side lengths using the equation we found earlier:
P1/P2 = [(a1a2)/(b1b2)]*[(a1 + a2 + a3)/(a1 + a2 + a3)]
P1/P2 = [(a1a2)/(b1b2)]*1
P1/P2 = (a1a2)/(b1b2)
We still don't know the values of a1, a2, b1, and b2, but we can eliminate them by using the equation we found earlier:
(50)/(98) = (a1a2)/(b1b2)
Simplifying this expression, we get:
(a1/a2) = sqrt((98/50)*(b1/b2))
We can use this to substitute for one of the ratios of side lengths in the equation for P1/P2:
P1/P2 = [(a1a2)/(b1b2)]*[(a1 + a2 + a3)/(a1 + a2 + a3)]
P1/P2 = [sqrt((98/50)(b1/b2))][(a1 + a2 + a3)/(a1 + a2 + a3)]
P1/P2 = sqrt((98/50)*(b1/b2))
Now we can substitute the given values to get:
P1/P2 = sqrt((98/50)(b1/b2)) = sqrt((98/50)(2/1)) = sqrt(196/50) = 14/5

a. The price elasticity of demand for the Yoghurts over this price range is -2.5
b. The demand is elastic
c. The change in revenue due to the change in price is GHS 20,000
a. The price elasticity of demand is given by the formula:
Price elasticity of demand = (Percentage change in quantity demanded) / (Percentage change in price)
The percentage change in quantity demanded is (6000 - 4000) / 4000 * 100% = 50%
The percentage change in price is (30 - 40) / 40 * 100% = -20%

If the base of the roof is 32 feet long, then the area of the triangular roof is 256 square feet.
In the given scenario, we are provided with information about a triangular roof. It is mentioned that the base of the roof is 32 feet long, and we need to determine the area of the triangular roof.
To calculate the area of a triangle, we need to know the length of the base and the height. In this case, we are given that the height is half the length of the base, which can be expressed as h = (1/2) * b.
Since we are given that the base length, b, is 32 feet, we can substitute this value into the height equation to find the height of the triangle: h = (1/2) * 32 feet = 16 feet.
Now that we have the base length (b = 32 feet) and the height (h = 16 feet), we can use the formula for the area of a triangle: A = (1/2) * b * h.
Substituting the values, we have A = (1/2) * 32 feet * 16 feet = 256 square feet.
Therefore, the area of the triangular roof is determined to be 256 square feet. This represents the amount of surface area covered by the triangular section of the roof.
Let the base of the triangular roof be denoted by b, and its height be denoted by h. We are given that
h = (1/2) * b, and that
b = 32 feet.
We can use this information to find the area A of the roof as follows:
A = (1/2) * b * h
= (1/2) * 32 feet * (1/2) * 32 feet

Brody is going to invest $350 and leave it in an account for 18 years. Assuming the interest is compounded daily, what interest rate, to the nearest tenth of a percent, would be required in order for Brody to end up with $790?
The interest rate is 4.5%, if the interest is compounded daily on an investment of $350.
To find the interest rate, compound interest formula
A= P(1+r/n)ⁿᵃ
where
A = The amount to be received
P = The Principal
r = The rate of interest
n = number of years (Here interest is compounded on daily basis. So, n =365)
a = Time period in years
Substitute the values in the formula,
790= 350(1+r/365)⁽³⁶⁵⁾⁽¹⁸⁾
790= 350(1+r/365)⁶⁵⁷⁰
790/350= (1+r/365)⁶⁵⁷⁰
Using logarithms property on both sides
ln(790/350)= 6570×ln(1+r/365)
By the property of logarithms, for small values of x ln(1+x) =x
(ln(790/350))/6570= r/365
Therefore
The rate of interest r = 4.5%

Suppose that f(x) = (x + 6)/(2-6) (A) Find all critical values of f. If there are no critical values, enter- None. If there are more than one, enter them separated by commas. Critical value(s) =?
The function f(x) = (x + 6)/(2-6) does not have any critical values. A critical value of a function is a value of x where the derivative of the function is either zero or undefined.
However, in this case, the denominator of f(x) is a constant, so the derivative of f(x) is simply the derivative of the numerator divided by the constant denominator.
The derivative of the numerator is 1, so the derivative of f(x) is simply 1/(2-6) = -1/4. Since the derivative is a constant, it is never zero or undefined, and so there are no critical values for this function.Explanation: To find the critical values of a function, we need to find the values of x where the derivative of the function is either zero or undefined.

(1 point) Find the maximal area of a right triangle with hypotenuse of length 3.
The maximal area of a right triangle with hypotenuse of length 3 is 0.
How to calculate the maximal area?Let's call the legs of the right triangle a and b.
Since the hypotenuse has length 3, we know that a² + b² = 3² = 9
The area of the triangle is given by A = 1/2 ab.
We want to maximize A subject to the constraint a² + b²= 9.
One way to do this is to use the method of Lagrange multipliers.
We want to maximize the function f(a, b) = 1/2 ab subject to the constraint g(a, b) = a²+ b² - 9= 0. The Lagrangian is then:
L(a, b, λ) = f(a, b) - λg(a, b) = 1/2 ab - λ(a² + b² - 9)
To find the maximum, we need to solve the system of equations:
∂L/∂a = 0∂L/∂b = 0∂L/∂λ = 0Taking the partial derivatives and setting them equal to zero, we get:
b/2 - 2λa = 0a/2 - 2λb = 0a² + b²- 9 = 0Solving the first two equations for a and b in terms of λ and plugging them into the third equation,
we get:
4λ² + 1 = 0
Then from the constraint a² + b² = 9, we have a = ±3.
The area of the triangle in this case is A = 1/2 ab = 0.
Therefore, the maximal area of a right triangle with hypotenuse of length 3 is 0, and it is achieved when one of the legs has length 0.

Therefore, the equivalent expression to [tex]9^2[/tex] is 81.
How to solve equation?To solve an equation, you need to isolate the variable on one side of the equation, typically the left side, and simplify the other side until you are left with an expression that has only the variable you are trying to solve for.
Here are the general steps to solve an equation:
Start by simplifying both sides of the equation as much as possible. This may involve distributing or combining like terms.
Get all terms with the variable you are solving for on one side of the equation. To do this, you can add or subtract terms from both sides of the equation. For example, if you have the equation 2x + 5 = 9, you can subtract 5 from both sides to get 2x = 4.
Isolate the variable by dividing both sides of the equation by its coefficient. In the above example, you can divide both sides by 2 to get x = 2.
Check your solution by plugging it back into the original equation and verifying that both sides of the equation are equal.
[tex]a^m/a^n = a^{(m-n)}[/tex]
to simplify the expression.
The expression [tex]9^2[/tex] means 9 multiplied by itself 2 times:
[tex]9^2 = 9 * 9[/tex]
Using the laws of exponents, we can rewrite this expression as:
[tex]9^2 = 9^{(1+1)} (since 2 = 1 + 1)[/tex]
Then, using the rule that [tex]a^{(m+n)} = a^m * a^n[/tex], we have:
[tex]9^2 = 9^1 *9^1[/tex]
Finally, using the fact that. [tex]a^1 = a[/tex] for any value of a, we get:
We can use the rule of exponents that states:
[tex]9^2 = 9 * 9 = 81[/tex]
Therefore, the equivalent expression to [tex]9^2[/tex] is 81

George says his bicycle has a mass of 15 grams. If he takes the front wheel off what could be the mass?
If George's bicycle has a mass of 15 grams, then it is highly unlikely that he has stated the correct mass, as 15 grams is an extremely low mass for a bicycle.
If George`s bicycle weighs 15 grams, what would be the resulting weight of it if he removes the front wheel?Determine if the givens mass of 15 grams is reasonable for a bicycle.A typical bicycle weighs anywhere from 7 to 15 kilograms. It is highly unlikely that a bicycle would weigh only 15 grams, as this is much lighter than the lightest bicycle ever made.
Therefore, it is reasonable to assume that George made a mistake and meant to say 15 kilograms instead of grams.
Calculate the mass of the bicycle without the front wheel.Assuming the mass of the bicycle is 15 kilograms, removing the front wheel will decrease the mass slightly, but not by a significant amount.
The front wheel typically accounts for around 1-2 kilograms of the total mass of the bicycle, so removing it would leave a mass of approximately 14 kilograms.
However, assuming he made a mistake and meant to say 15 kilograms, then the mass of the bicycle without the front wheel would be approximately 14 kilograms.

Find the open intervals where the function is concave upward or concave downward. Find any inflection points. f(x) = 11x - 11 e - Where is the function concave upward and where is it concave downward?
The function f(x) = 11x - 11e^(-x) is concave upward on the interval (-∞, ln(11)) and concave downward on the interval (ln(11), ∞). The inflection point is at x = ln(11).
Find the first and second derivatives of the function f(x):
f'(x) = 11 + 11e^(-x)
f''(x) = 11e^(-x)
Set the second derivative equal to zero to find any potential inflection points:
11e^(-x) = 0
e^(-x) = 0
There are no solutions to this equation, so there are no inflection points in the function.
Determine the sign of the second derivative on either side of the potential inflection point(s) to identify the intervals of concavity:
For x < ln(11), e^(-x) > 0, so f''(x) > 0, meaning the function is concave upward on the interval (-∞, ln(11)).
For x > ln(11), e^(-x) < 0, so f''(x) < 0, meaning the function is concave downward on the interval (ln(11), ∞).
Therefore, the final answer is: The function f(x) = 11x - 11e^(-x) is concave upward on the interval (-∞, ln(11)) and concave downward on the interval (ln(11), ∞). The inflection point is at x = ln(11).
