One of the legs of the right triangle measure 12 cm and it’s hypotenuse measure 8 cm

Answer:

Step-by-step explanation:

To find g(4), we substitute x = 4 into the expression for g(x):

g(4) = -3(4) - 4 = -12 - 4 = -16

To find g(4) + 8, we add 8 to the value we just found for g(4):

g(4) + 8 = -16 + 8 = -8

Therefore, g(4) + 8 = -8.

Step-by-step explanation:

In order to find an equation that is parallel, it must have the same slope. This means the y intercept could literally be anything.

By equation of the line, we can write it in point slope form

[tex]y-y1=m(x-x1)[/tex]

where y1 and x1 are points on the coordinate plane and m is the slope.

We are already given the slope, so we just plug in the numbers.

Approximately 95% of scores lie between -1.96 and 1.96 z-scores. This is because the area under the standard normal distribution curve between these two values is approximately 0.95.

To calculate this, first calculate the area under the standard normal distribution curve between -1.96 and 1.96. This can be done by using a Z-score table, which provides the area under the curve to the left of a given value. To calculate the area between -1.96 and 1.96, subtract the area to the left of -1.96 from the area to the left of 1.96. This is approximately 0.95.

Since the total area under the curve is 1, this implies that approximately 95% of scores lie between -1.96 and 1.96 z-scores. This is commonly known as the "95% Rule," and it is a useful way to quickly estimate the amount of scores that are within a certain range.

It is important to note that this calculation is only an approximation, as the exact value depends on the actual values that are used. Therefore, it is important to use a Z-score table with more accurate values if more precision is needed.

Answer:

a) The perimeter of the room is the sum of the lengths of all four sides. The length of two opposite sides is 4x + 3, and the length of the other two opposite sides is 3x. Therefore, the perimeter is:

P = 2(4x + 3) + 2(3x) = 14x + 6

b) The area of the room is the product of the length, width, and height. The length is 4x + 3, the width is 3x, and the height is 3x. Therefore, the area is:

A = (4x + 3)(3x)(3x) = 27x^2 + 12x

c) If both the length and width are doubled, the new dimensions are 2(4x + 3) = 8x + 6 for the length and 2(3x) = 6x for the width.

a) The new perimeter is the sum of the lengths of all four sides:

P' = 2(8x + 6) + 2(6x) = 28x + 12

b) The new area is the product of the length, width, and height:

A' = (8x + 6)(6x)(3x) = 144x^2 + 72x

d) The new perimeter is not twice the original perimeter because:

P' = 28x + 12

2P = 28x + 12 + 28x + 12 = 56x + 24

Therefore, 2P is not equal to P', so doubling the length and width does not double the perimeter.

e) The new area is not twice the original area because:

A' = 144x^2 + 72x

2A = 2(27x^2 + 12x) = 54x^2 + 24x

Therefore, 2A is not equal to A', so doubling the length and width does not double the area.

The answer of the given question based on the supplementary angle is  the two angles are 58° degrees and 122° degrees.

An angle is a geometric figure that is formed by two rays or lines that share a common endpoint, called the vertex. The rays or lines are called  sides or arms of  angle. Angles are typically measured in the degrees or the radians.

The measure of an angle is determined by the amount of rotation needed to bring one of its sides into coincidence with the other side. A full rotation is 360° degrees, so an angle that is half of a full rotation is 180 degrees, an angle that is a quarter of a full rotation is 90° degrees, and so on.

Let's call the two angles "x" and "y". We know that they are supplementary, which means that their sum is 180° degrees:

x + y = 180

We also know that one angle (let's say "x") is two times the sum of the other angle (y) and 3:

x = 2(y + 3)

Now we can substitute the second equation into the first equation to eliminate "x":

(2(y + 3)) + y = 180

Simplifying the equation, we get:

3y + 6 = 180

Subtracting 6 from both sides, we get:

3y = 174

Dividing both sides by 3, we get:

y = 58

Now that we know "y", we can substitute it back into the equation for "x" to find its value:

x = 2(y + 3) = 2(58 + 3) = 122

Therefore, the two angles are 58° degrees and 122° degrees.

Using coordinate geometry,

The problem provides two pieces of information about Hannah's jogging routine: she started with 3 41 miles and added 1/21 miles every week. We can use this information to create a linear equation that represents the number of miles Hannah jogged as a function of the number of weeks she has been jogging.

To create this equation, we first identify the starting value, which is 3 41 miles. This is also the y-intercept of the line. Next, we determine the slope of the line, which is the rate at which the number of miles increases each week. The slope is equal to the change in y (miles) divided by the change in x (weeks), which in this case is (1/21 - 3/41)/1 = -2/1 = -2. Therefore, the slope of the line is -2.

Putting these two pieces of information together, we get the equation y = -2x + 3 41, where y is the number of miles jogging and x is the number of weeks of jogging. This is a linear equation in slope-intercept form, where the slope is -2 and the y-intercept is 3 41.

6. f(x)g(x)+h(x) = 20x3-4x. This answer is arrived at by using the rules of algebra and the values of the given functions.

7. f(x)g(x) = -15x2 - 18x - 15

Polynomials are algebraic expressions consisting of variables and coefficients that are combined through addition, subtraction, multiplication and division operations. For example, the polynomial 4x² + 3x - 5 can be written as the sum of 4x², 3x and -5.

6. In order to calculate f(x) g(x)+h(x), it is necessary to first multiply f(x) and g(x). Since f(x)=4x and g(x) = 5x2-4, it follows that f(x)g(x)=20x3-4x. Next, it is necessary to add h(x) to this product. Since h(x) = 9x, it follows that f(x)g(x)+h(x) = 20x3-4x+9x = 20x3-4x. Since each coefficient is correctly represented in the answer, it follows that the correct answer is 20x3-4x.

Multiplying f(x) and g(x) gives the product of 20x3-4x, and adding h(x) to this product gives the sum of 20x3-4x. As each coefficient is correctly represented in the answer, the correct answer is 20x3-4x.

7. The product of two polynomials is found by multiplying each term of one polynomial by each term of the other polynomial. This is known as the FOIL method (First, Outer, Inner, Last).

The first term is the product of the first terms of each polynomial, which is 3x x 4x = 12x2.

The second term is the product of the outer terms, which is 3x x -5x = -15x2.

The third term is the product of the inner terms, which is 5 x -5x = -25x.

Finally, the fourth term is the product of the last terms of each polynomial, which is 5 x -3 = -15.

We can now combine the terms to get the product of the two polynomials, which is:

f(x)g(x) = -15x2 - 18x - 15.

Therefore, the correct coefficient for each term is -15x2 for the first term, -18x for the second term, and -15 for the third term.

The probability that a randomly chosen college student will spend between $300 and $400 on clothing in a year is approximately 0.6645 or 66.45%.

To solve this problem, we need to standardize the given range of values using the z-score formula:

z = (x - μ) / σ

where x is the value of interest, μ is the mean, and σ is the standard deviation. For x = 300:

z = (300 - 310) / 50 = -0.2

For x = 400:

z = (400 - 310) / 50 = 1.8

Using a standard normal distribution table or calculator, we can find the probability of the z-score being between -0.2 and 1.8:

passenger on the train spends approximately 4.65 seconds in the tunnel.

First, we need to convert the speed of the train from km/h to m/s (meters per second) since the length of the tunnel is given in meters. We can do this by dividing the speed in km/h by 3.6, which is the conversion factor from km/h to m/s:

Speed of the train = 120 km/h = (120/3.6) m/s = 33.33 m/s

Next, we can use the formula for time:

time = distance ÷ speed

where distance is the length of the tunnel, and speed is the speed of the train.

Plugging in the given values, we get:

time = 155 m ÷ 33.33 m/s ≈ 4.65 s
