According to the given information in the question to find the length of side v in triangle VWX, we can use the Law of Sines. the length of side v is approximately [tex]281.8[/tex] cm.
What do mathematicians mean by centimetres?image for "define centimeters in high-level mathematics." A centimeter is a metric unit used to quantify small distances and the object's length. Cm is used to represent it in writing.
It can also be described as the measure of length in the current metric system, referred to as the International System of Units (SI). It is equal to one-hundredth of a meter.
which states that:
[tex]a/sin(A) = b/sin(B) = c/sin(C)[/tex]
where a, b, and c are the lengths of the sides of the triangle, and A, B, and C are the opposite angles.
In this case, we know the length of side w (600 cm), and the measures of angles V and W.
To find the length of side v, we can use the Law of Sines with sides v and w and angle V:
[tex]v/sin(V) = w/sin(W)[/tex]
[tex]v/sin(26^\circ) = 600/sin(80^\circ)[/tex]
[tex]v = (600 \times sin(26^\circ))/sin(80^\circ)[/tex]
[tex]v \approx 281.8 cm[/tex] (rounded to the nearest 10th of a centimeter)
Therefore, the length of side v is approximately [tex]281.8 cm[/tex].

A He can put $250 into a savings account that pays 3. 8% interest and pay down his credit card debt with the rest.
B. He can put all the birthday money in the 3. 8% savings account
о
C. He can use all the money to pay down his credit card debt.
O D. He can invest $200 in the stock market and pay down his credit card debt with the rest.
The most responsible choice for Nick regarding his birthday money would be option C, which is to use all the money to pay down his credit card debt.
This is because credit card debt generally comes with high- interest rates, and it can be grueling to pay off the debt if the interest keeps adding up. By using the$ 500 to pay down his credit card debt, Nick can reduce the quantum he owes and, as a result, pay lower interest in the long run. Options A and D suggest unyoking the plutocrat between paying down debt and investing/ saving, which may not be the stylish choice given Nick's current fiscal situation.
Option B suggests putting all the plutocrat into a savings regard with a lower interest rate, which would not be as effective in reducing his credit card debt. thus, option C is the most responsible choice for Nick.

Devonte is studying for a history test he uses 1/8 of a side of one sheet of paper to write notes for each history event he fills 2 full sides of one sheet paper. which expression could be used to find how many events
The expression to find the number of events is: (1 event) / (1/8 side) = (n events) / (1/4 sides).
Devonte is studying for a history test and uses 1/8 of a side of one sheet of paper to write notes for each history event. He fills 2 full sides of one sheet of paper. To find out how many events he wrote notes for, you can set up an expression using the given information.
Since Devonte uses 1/8 of a side for each event, and he fills 2 sides, you can calculate the total amount of space he used by multiplying the fractions: (1/8) * 2. This simplifies to 2/8 or 1/4. Now, you can set up a proportion to find the number of events (n) that Devonte wrote notes for:
(1 event) / (1/8 side) = (n events) / (1/4 sides)
Cross-multiply to solve for n:
1 * (1/4) = n * (1/8)
1/4 = n/8
To find n, multiply both sides by 8:
(8) * (1/4) = n
2 = n
So, Devonte wrote notes for 2 history events using the 2 full sides of one sheet of paper. The expression to find the number of events is: (1 event) / (1/8 side) = (n events) / (1/4 sides).

Answer:
147 mm^2
Step-by-step explanation: The surface area has to be more, but not double the smaller figures surface area therefore the answer is 147 mm^2
The requried surface area of the larger solid is approximately 147 mm². Option A is correct.
What is surface area?The surface area of any shape is the area of the shape that is faced or the Surface area is the amount of area covering the exterior of a 3D shape.
Let's call the larger solid's surface area S.
Since the two solids are similar, their volumes have a ratio of (side length)³. Let's call the ratio of the side lengths of the larger to the smaller solid as k. Then:
[tex](k^3)(540 mm^3) = 857.5 mm^3[/tex]
Simplifying the above equation, we get:
[tex]k = (857.5/540)^{(1/3)}[/tex] =7/6
So, the larger solid is about 7/6=1.183 times bigger than the smaller solid in terms of side length. Since the surface area has a ratio of [tex](side length)^2[/tex], we can find the surface area of the larger solid by:
[tex]S = (1.183^2)(108 mm^2) \approx 147 mm^2[/tex]
Therefore, the surface area of the larger solid is approximately 147 mm². Answer: A.

(a) Find an equation of the tangent plane to the surface at the given point. z = x2 - y2, (5, 4, 9) X-5 (b) Find a set of symmetric equations for the normal line to the surface at the given point. Х y z 10 -8 -1 y - 4 Z - 9 10 -8 -1 Ox - 5 = y - 4 = Z - 9 X + 5 y + 4 Z +9 10 -8 -1 Ox + 5 = y + 4 = 2 + 9 =
z - 9 = 10(x - 5) - 8(y - 4) this is the equation of the tangent plane at the point (5, 4, 9). (x - 5)/10 = (y - 4)/(-8) = (z - 9)/(-1). These are the symmetric equations for the normal line to the surface at the given point.
(a) To find the equation of the tangent plane to the surface z = x^2 - y^2 at the point (5, 4, 9), we first need to find the partial derivatives with respect to x and y:
∂z/∂x = 2x
∂z/∂y = -2y
Now, we evaluate these at the given points (5, 4, 9):
∂z/∂x(5, 4) = 2(5) = 10
∂z/∂y(5, 4) = -2(4) = -8
Using the tangent plane equation:
z - z₀ = ∂z/∂x (x - x₀) + ∂z/∂y (y - y₀)
Plugging in the values:
z - 9 = 10(x - 5) - 8(y - 4)
This is the equation of the tangent plane at the point (5, 4, 9).
(b) The normal vector to the surface at the given point is given by the gradient vector (∂z/∂x, ∂z/∂y, -1) = (10, -8, -1). To find the symmetric equations for the normal line, we use the point-normal form:
(x - x₀)/a = (y - y₀)/b = (z - z₀)/c
Plugging in the point (5, 4, 9) and the normal vector components (10, -8, -1):
(x - 5)/10 = (y - 4)/(-8) = (z - 9)/(-1)
These are the symmetric equations for the normal line to the surface at the given point.

A real-world situation that might involve three linear equations in three variables is trying to determine the ages of three siblings.
Let's call them A, B, and C. We know that the sum of all three ages is a certain value, let's say it's 60. We also know the sum of the first two ages is either twice the third age or the third age squared. For example, if the sum of the first two ages is twice the third age, we could write it as A + B = 2C.
Alternatively, if the sum of the first two ages is the third age squared, we could write it as A + B = C^2. Similarly, we know the sum of the first and third ages is either twice the second age or the square root of the second age. So, we could write it as A + C = 2B or A + C = sqrt(B).
We now have three linear equations in three variables that we can use to solve for the ages of the three siblings. By solving the system of equations, we can find out how old each sibling is.

Answer:
P = (5.4, -2.6)
Step-by-step explanation:
[tex]\boxed{\begin{minipage}{5 cm}\underline{Equation of a circle}\\\\$(x-h)^2+(y-k)^2=r^2$\\\\where:\\ \phantom{ww}$\bullet$ $(h,k)$ is the center. \\ \phantom{ww}$\bullet$ $r$ is the radius.\\\end{minipage}}[/tex]
As the given circle has a radius of 6 units and is centred at the origin, the equation of the circle is:
[tex]x^2+y^2=36[/tex]
The formula for the equation of the tangent line to a circle with the equation x² + y² = a² is:
[tex]\boxed{y = mx \pm a \sqrt{1+ m^2}}[/tex]
where:
m is the slope.a is the radius of the circle.To find the slope of the equation of the tangent line to the circle that passes through the point (0, -14), substitute a = 6, x = 0 and y = -14 into the formula and solve for m:
[tex]\implies -14 = m(0) \pm 6 \sqrt{1+ m^2}[/tex]
[tex]\implies -14 = \pm 6 \sqrt{1+ m^2}[/tex]
[tex]\implies \pm\dfrac{14}{6} =\sqrt{1+ m^2}[/tex]
[tex]\implies \left(\pm\dfrac{14}{6}\right)^2 =1+m^2[/tex]
[tex]\implies m^2= \left(\pm\dfrac{14}{6}\right)^2-1[/tex]
[tex]\implies m^2=\dfrac{40}{9}[/tex]
[tex]\implies \sqrt{m^2}= \sqrt{\dfrac{40}{9}}[/tex]
[tex]\implies m=\pm\sqrt{\dfrac{40}{9}}[/tex]
[tex]\implies m=\pm\dfrac{2\sqrt{10}}{3}[/tex]
The slope-intercept form of a straight line is y = mx + b, where m is the slope and b is the y-intercept.
As the slope of the given tangent line is positive, and the y-intercept is (0, -14), the equation of the tangent line is:
[tex]\boxed{y=\dfrac{2\sqrt{10}}{3}x-14}[/tex]
As point P is the point of intersection of the circle and the tangent line, substitute the tangent line into the equation of the circle and solve for x:
[tex]x^2+\left(\dfrac{2\sqrt{10}}{3}x-14\right)^2=36[/tex]
Expand the brackets:
[tex]x^2 +\dfrac{40}{9}x^2-\dfrac{56\sqrt{10}}{3}x+196=36[/tex]
Subtract 36 from both sides of the equation:
[tex]\dfrac{49}{9}x^2-\dfrac{56\sqrt{10}}{3}x+160=0[/tex]
Multiply both sides of the equation by 9:
[tex]49x^2-168\sqrt{10}x+1440=0[/tex]
Rewrite the equation in the form a² - 2ab + b²:
[tex](7x)^2-2 \cdot 7 \cdot 12\sqrt{10}x+(12\sqrt{10})^2=0[/tex]
Apply the Perfect Square formula: a² - 2ab + b² = (a - b)²
[tex](7x-12\sqrt{10})^2=0[/tex]
Solve for x:
[tex]7x-12\sqrt{10}=0[/tex]
[tex]7x=12\sqrt{10}[/tex]
[tex]x=\dfrac{12\sqrt{10}}{7}[/tex]
To find the y-coordinate of point P, substitute the found value of x into the equation of the tangent line:
[tex]y=\dfrac{2\sqrt{10}}{3}\left(\dfrac{12\sqrt{10}}{7}\right)-14[/tex]
[tex]y=\dfrac{2\sqrt{10}\cdot 12\sqrt{10}}{3\cdot 7}\right)-14[/tex]
[tex]y=\dfrac{240}{21}-14[/tex]
[tex]y=\dfrac{80}{7}-\dfrac{98}{7}[/tex]
[tex]y=-\dfrac{18}{7}[/tex]
Therefore, the exact coordinates of point P are:

840x - x2 A company's revenue for selling x (thousand) items is given by R(x) = x2 +840 Find the value of x that maximizes the revenue and find the maximum revenue. X= maximum revenue is $ 2
The value of x that maximizes revenue is x 28.99 and maximum revenue is $1680 (thousand).
The revenue function for a company that sells x (thousand) items is R(x) = x² + 840. To find the value of x that maximizes revenue, we need to differentiate the revenue function, set it equal to zero and solve for x. The maximum revenue can then be calculated by substituting the value of x into the revenue function.
Revenue function: R(x) = x² + 840
To find the value of x that maximizes revenue, we differentiate the revenue function with respect to x:
dR/dx = 2x
Setting this equal to zero, we get:
2x = 0
x = 0
However, this value does not make sense in the context of the problem, as the company cannot sell 0 items. Therefore, we need to consider the critical points of the function, which occur when dR/dx = 0 or is undefined.
dR/dx = 0 when 2x = 0, so x = 0 is a critical point.
dR/dx is undefined when x = ±√840, so these are also critical points.
We can use the second derivative test to determine which critical point corresponds to a maximum. The second derivative of the revenue function is:
d²R/dx² = 2
At x = 0, d²R/dx² = 2 > 0, so this critical point corresponds to a minimum.
At x = ±√840, d²R/dx² = 2 > 0, so these critical points correspond to a minimum.
Therefore, the value of x that maximizes revenue is x = √840 ≈ 28.99 (thousand items).
To find the maximum revenue, we substitute x = √840 into the revenue function:
R(√840) = (√840)² + 840 = 1680
So the maximum revenue is $1680 (thousand).

Event A' has a probability of 50% (25% for freshmen + 25% for seniors).
To determine Event A', we need to first identify what Event A represents. Event A is the probability that a student is a sophomore or junior. Since students have equal probabilities of being freshmen, sophomores, juniors, or seniors, the probability of Event A is 50% (25% for sophomores + 25% for juniors).
Event A' is the complement of Event A, which means it includes the other two grade levels not included in Event A, in this case, freshmen and seniors. Therefore, Event A' is the probability that a student is a freshman or a senior.

In Year 6 at Woodland Junior School, there are 90 children split into three classes of 14, 24, and 12 on the basis of there selection of sports. In 6M, 14 not chose hockey, and the rest of the class was split equally between football and netball. In 6P, 24 not chose netball, 16 chose football, and 8 choose hockey In 6T, the ratio of football to netball to hockey was 1:2:3. The completed table is shown.
To complete the table, we need to distribute the remaining children who did not choose their sport in each class. Here's how we can calculate it
In 6M, the number of children who did not choose hockey is 27 - 13 = 14.
Since the rest of the class was split equally between football and netball, each of these two sports will have 14/2 = 7 children.
In 6P, the number of children who did not choose netball is 33 - 9 = 24.
Since twice as many children chose football as chose hockey, we can write the number of footballers as 2x, and the number of hockey players as x. Then we have 2x + x + 9 = 33, which gives x = 8. Therefore, we have 16 children who chose football, and 8 children who chose hockey. The number of children who did not choose any of these two sports is 33 - 16 - 8 - 9 = 0.
In 6T, the ratio of children who chose football to netball to hockey was 1:2:3. Let's call the number of children who chose netball as 2x, and the number of children who chose hockey as 3x. Then we have x + 2x + 3x = 30, which gives x = 6. Therefore, we have 6 children who chose football, 12 children who chose netball, and 18 children who chose hockey.
Thus, the completed table is shown.

Find the derivative y = cos(sin(14x-13))
To find the derivative of y = cos(sin(14x-13)), we will use the chain rule.
Let's start by defining two functions:
u = sin(14x-13)
v = cos(u)
We can now apply the chain rule:
dy/dx = dv/du * du/dx
First, let's find dv/du:
dv/du = -sin(u)
Next, let's find du/dx:
du/dx = 14*cos(14x-13)
Now we can put it all together:
dy/dx = dv/du * du/dx
dy/dx = -sin(u) * 14*cos(14x-13)
But we still need to substitute u = sin(14x-13) back in:
dy/dx = -sin(sin(14x-13)) * 14*cos(14x-13)
So the derivative of y = cos(sin(14x-13)) is:
dy/dx = -14*sin(sin(14x-13)) * cos(14x-13)
To find the derivative of the function y = cos(sin(14x - 13)), we can use the chain rule. The chain rule states that the derivative of a composite function is the derivative of the outer function times the derivative of the inner function.
Let u = sin(14x - 13), so y = cos(u). Now we find the derivatives:
1. dy/du = -sin(u)
2. du/dx = 14cos(14x - 13)
Now, using the chain rule, we get:
dy/dx = dy/du × du/dx
dy/dx = -sin(u) × 14cos(14x - 13)
Since u = sin(14x - 13), we can substitute back in:
dy/dx = -sin(sin(14x - 13)) × 14cos(14x - 13)

what’s the coefficients of the polynomials?
The numbers preceding a variable
Step-by-step explanation:The coefficients are the number before the variable.
Finding Coefficients
All variables are multiplied by some coefficient. Sometimes those coefficients are one or another number. Take the variable 5x. The coefficient is 5. Since 5 is the number that comes before the variable, it is the coefficient. Additionally, the variable x has a coefficient of 1 because x is multiplied by 1.
Polynomial Example
Every variable within a polynomial can have a unique variable. For example, 3x⁶+5x³+2x². The first coefficient is 3, then 5, then 2. Coefficients are simply the constants that a variable is multiplied by. It does not matter what the variable is or the exponent.
Si al triple de la edad que tengo, se quita mi edad aumentada en 8 años, tendría 36 años. ¿Qué edad tengo?
damePor lo tanto, la edad que tienes es de aproximante 14.67 años.
Si al triple de la edad que tengo, se quita mi edad aumentada en 8 años, tendría 36 años. ¿
Podemos plantear este problema como una ecuación algebraica. Si llamamos "x" a la edad que tienes, la ecuación sería:
3x - 8 = 36
Ahora, despejamos la variable "x" para encontrar su valor:
3x = 36 + 8
3x = 44
x = 44/3
.Este resultado nos indica que nuestra edad actual es de aproximadamente 14.67 años. Es importante tener en cuenta que la solución no es un número entero, lo cual puede parecer inusual para una edad, pero es una respuesta matemáticamente correcta según la ecuación planteada en el problema.

Answer:
4x² - x + 2--------------------------
Let the equal sides be both marked as ?
Use the perimeter formula to determine one of the equal sides.
P = 2(?) + x(4x - 3)Substitute the expression for the perimeter and find the value of ?
12x² - 5x + 4 = 2(?) + x(4x - 3)12x² - 5x + 4 = 2(?) + 4x² - 3x2(?) = 12x² - 5x + 4 - 4x² + 3x2(?) = 8x² - 2x + 4? = 4x² - x + 2Hence the length of each of equal sides is 4x² - x + 2.
