Step-by-step explanation:

Formula

c^2 = a^2 + b^2

Givens

Solution

c^2 = 3^2 + 8^2                 Substitute givens

c^2 = 9 + 64                       Combine

c^2 = 73                             Take the square root of both sides

√c^2 = √73  

c = √73                        \

Exact answer

c = √73                                73 is prime. It will break down no further

Approximate answer

c = 8.54400                         Both zeros must be entered

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

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

Step-by-step explanation:

The answer to this question is choice C

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

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

Full Question

Determine any data values that are missing from the table, assuming that the data represent a linear function.

the sides of a 30 60 90 triangle are x, 2x, and [tex]x\sqrt{3}[/tex], with [tex]x\sqrt{3}[/tex] being opposite to the 60 degree angle, and x being adjacent to the 60 degree angle. If [tex]x\sqrt{3}[/tex] = 15 (as given from the image), you can calculate x to be [tex]5\sqrt{3}[/tex].

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]

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]

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.

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.

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

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:

Hence:

[tex]x^2 + 4^2 = 12^2[/tex]

[tex]x = \sqrt{12^2 - 4^2}[/tex]

x = 11.3 inches.

The attached graph represents a histogram that has a range of 55

The range is given as:

Range = 55

The range is calculated as:

Range = Maximum - Minimum

So, we have:

Maximum - Minimum = 55

Rewrite as:

Maximum = Minimum + 55

Let the minimum be 10.

So, we have:

Maximum = 10 + 55

Evaluate

Maximum = 65

The following dataset can be used to create the histogram
