Answer:

f(g(5)) = 5

g(f(4)) = 0

f(f(6))=1

g(g(9)) = 0

Step-by-step explanation:

Given

The attached table of values

Solving (a): f(g(5))

First, we solve for g(5)

g(5) = 7

So:

f(g(5)) = f(7)

Next, we solve for f(7).

From the table

f(7) = 5

So:

f(g(5)) = 5

Solving (b): g(f(4))

First, we solve for f(4)

f(4) = 6

So:

g(f(4)) = g(6)

Next, we solve for g(6).

From the table

g(6) = 0

So:

g(f(4)) = 0

Solving (c): f(f(6))

First, we solve for f(6)

f(6) = 8

So:

f(f(6)) = f(8)

Next, we solve for f(8).

From the table

f(8) = 1

So:

f(f(6))=1

Solving (d): g(g(9))

First, we solve for g(9)

g(9) = 6

So:

g(g(9)) = g(6)

Next, we solve for g(6).

From the table

g(6) = 0

So:

g(g(9)) = 0

3. Find the area of the shaded region. Leave your answer in terms of pi. (1 point)
anygoal [31]

ANSWER

B.

(4 - \pi) {ft}^{2}

EXPLANATION

The area of the square is

{l}^{2}

The length of the square is

l = 2ft

The area of the square is

=  {2}^{2}  = 4 {ft}^{2}

Area of the circle is

= \pi \:  {r}^{2}

The radius of the circle is

r =  \frac{2}{2}  = 1ft

Area of circle is

= \pi \:  \times  {1}^{2}  = \pi {ft}^{2}

The area of the shaded region is

= (4 - \pi) {ft}^{2}

For the right triangles below, find the exact values of the side lengths b and d.
Ivanshal [37]

Answer:

Step-by-step explanation:

The question lacks the required diagram. Find the diagram attached below;

According to the first triangle, taking 30° as the reference angle, the opposite side of the triangle will be 5 and the adjacent will be the unknown side "b"

According to SOH, CAH, TOA;

tanθ = opposite/adjacent (using TOA)

Given;

θ = 30°, opposite = 5 and adjacent = b

tan30° = 5/b

b = 5/tan30°

b = 5/(1/√3)

b = 5*√3/1

b = 5√3

According to the 45° triangle, the opposite side of the triangle will be d and the hypotenuse will be 7

Using SOH;

sinθ = opposite/hypotenuse

Given;

θ = 45°, opposite = d and adjacent = 7

sin45° = d/7

d = 7sin45°

d = 7(1/√2)

d = 7/√2

Rationalize 7/√2

= 7/√2*√2/√2

=7√2/2

Hence the value of d is 7√2/2

I will give you extra point and mark you braniest if you give me an explanation on how to find the answer.
EastWind [94]

Answer:

Step-by-step explanation:

The surface area of a cylinder is 2pi *rh + 2pir^2, where r and h are radius and height, respectively. (If you want me to explain this, comment down below). Anyways, we can simply plug in 11 and 8 in the formula, so 2* 8*11*pi + 2* pi * 8^2=304pi. Thus, we do 304 * 3.14=954.56.

A number is multiplied by 20, and that product is added to 5. The sum is equal to the product of 5 and 13.
liubo4ka [24]

Answer:

x = 3

Step-by-step explanation:

First, you will pick the first equation :

(x*20)

Then the next,

(x*20) + 5

Then the last equation,

(x*20) + 5 = 5*13

Then you solve

20x + 5 = 65

20x = 65 - 5

20x = 60

20x/20 = 60/20

x = 3
