For the given functions f and g find f•g and state it’s domain

f(x) = 3x - 6; g(x) = 8x +4

Answers

The function is (c) (f.g)(x) = 24x^2 - 36x - 24; domain of all set of real numbers

How to determine the composite functions?

The given parameters are:

f(x) = 3x - 6; g(x) = 8x +4

The composite function is calculated as:

(f.g)(x) = f(x) * g(x)

This gives

(f.g)(x) = (3x - 6) * (8x + 4)

Expand

(f.g)(x) = 24x^2 + 12x - 48x - 24

Evaluate the difference

(f.g)(x) = 24x^2 - 36x - 24

The above function is a quadratic function;

Quadratic functions have a domain of all set of real numbers

Hence, the function is (c) (f.g)(x) = 24x^2 - 36x - 24; domain of all set of real numbers

Find the height of the triangle by applying formulas for the area of a triangle and your knowledge about triangles.
This is a triangle. side a has a length of 12 inches. side b has a length of 12 inches. side c has a length of 8 inches. The altitude to side c has a length of X inches.

Answers

Using the Pythagorean Theorem, the altitude to side c has a length of 11.3 inches.

What is the Pythagorean Theorem?

The Pythagorean Theorem relates the length of the legs [tex]l_1[/tex] and [tex]l_2[/tex] of a right triangle with the length of the hypotenuse h, according to the following equation:

[tex]h^2 = l_1^2 + l_2^2[/tex]

To find the altitude relative to side c, we bisect this side, which cuts it's length into half(now of 4 inches), forming a right triangle in which:

The altitude is the other leg.The side of 12 inches is the hypotenuse.

Volume and surface area

Answer:

The 1st one is 540π

The 2nd one is 1696.46

Step-by-step explanation:

To find the volume of a cylinder, you do the following:

[tex](r)^2\pi \times h[/tex]

Where r represents the radius of the circle and h represents the height. Because it's multiplication, we can change it to:

[tex]r^2\times h \times \pi[/tex]

So since the radius is 6, 6^2 is 36. Then we multiply by 15, to get 540. Then now since we don't need to multiply the pi, you just leave it as 540π.

For the second one, multiply 540 by pi to get the answer, then round it to the nearest hudredth to get 1696.46.

The swimming pool at Spring Valley High School is a rectangle with a width of 70 meters and a length of 30 meters. Around the perimeter of the pool is a tiled floor that extends w meters from the pool on all sides. Find an expression for the area of the tiled floor.

Answers

The expression that can be used to find the area of the tiled floor is 4w² + 200w

Area of rectangle

Original rectangle:

Length = 70 Meters

Width = 30 meters

Area = length × width

= 70 × 30

= 2100

New rectangle(including tiled floor):

Length = 70 + 2w meters

Width = 30 + 2w meters

Area = length × width

= (70+2w) (30+2w)

= 2100 + 140w + 60w + 4w²

= 4w² + 200w + 2100

Area of the tiled floor = Area of new rectangle - area of old rectangle

= (4w² + 200w + 2100) - 2100

= 4w² + 200w + 2100 - 2100

This exercise is about Linear Functions. From the values given, we can state that:

The value of missing x = 6The value of missing y = 21 (Option D)

What is the explanation for the above?

Given that the table represents a  linear function, so the function is a straight line.

Taking two points

(-12, 17)

(-10, 19)

To determine the slope between (-12, 17) and (-10, 19), we need to use the formula:

Slope = (y2-y1)/(x2 - x1)

Recall that:

(x1, y1) = (-12, 17); and

(x2, y2) = (-10, 19)

m = 19 -17/-10 -17

m = 1

Leveraging the point-slope to create the linear equation, we have:

y-y1 = m(x-x1)

where m is the slope of the line and (x₁, y₁) is the point substituting the values m = 1 and the point (-12, 17). Hence, we have:

y-y1 = m(x-x1)

→ y-17 = 1 (x-(-12))

→ y - 17 = x +12

y = x + 12 + 17

y = x + 29 ..................................Linear Equation

Next, we substitute x = -8 into the Linear Equation

y = (-8) + 29
y = 21

Hence, the missing y = 21; and

The missing x = -8

If we substitute y = 23 into the equation, we have:

y = x + 29
23 = x + 29
x = 29 - 23

x = 6

Thus, when the value of y = 23, the missing x is = 6

Conclusively,

The value of missing x = 6

The value of missing y = 21

(a) The square

For all rectangles, the area is the length multiplied by the height. For squares (a special type of rectangle), the length and height are the same, so you just use [tex]s^2[/tex], where [tex]s[/tex] is the side length.

[tex]A=s^2=16^2=\boxed{256}[/tex]

(b) The circle

The formula for the area of the circle is [tex]\pi r^2[/tex], where [tex]\pi[/tex] is pi, a constant, and [tex]r[/tex] is the radius of the circle, or the length from the center point to the edge.

We're given the side length of the square, which is the same as the diameter of the circle (length from edge to edge going through the center point). Divide the diameter by [tex]2[/tex] to get the radius of [tex]8[/tex] kilometers.

[tex]A=\pi r^2=\pi8^2=\boxed{64\pi}\approx201.1[/tex]

(c) The blue section

The area of the blue section is simply the area of the square minus the area of the circle since we just want what's left over.

[tex]A=\boxed{256-64\pi}\approx54.9[/tex]

You can keep the answer exact (the boxed expression) or use the approximate value of 54.9, depending on the instructions for the assignment.
