(f\circ g)(x)=f(g(x))=4(x^2-5)+1=4x^2-19

(f\circ g)(4)=4\cdot4^2-19=64-19=\boxed{45}

Hope this helps.

How much interest is earned on $1470 at 4% for six months
Elenna [48]

Answer:

$29.4

Step-by-step explanation:

I assume the question is based on simple interest since you didn't specify

Using simple interest

Simple interest=P×R×T

Where,

P=principal=$1470

R=interest rate=4%=0.04

T=time=6 months=0.5 year

Simple interest=P×R×T

=1470×0.04×0.5

=29.4

Interest earned=$29.4

Solve for x<br> And show work
klemol [59]

Answer:

x = -8

Step-by-step explanation:

1. Because the line the angles x + 96 and 100 + x are on is straight, it's a straight angle that results in 180°.

2. Given the above information, that means x + 96 + 100 + x = 180.

3. (Solving for equation above)

Step 1: Simplify both sides of the equation.

  • (x+x) + (96+100)=180
  • 2x + 196 = 180

Step 2: Subtract 196 from both sides.

  • 2x + 196 - 196 = 180 - 196
  • 2x = -16

Step 3: Divide both sides by 2.

  • \frac{2x}{2} = \frac{-16}{2}
  • x = -8

Step 4: Check if solution is correct.

  • -8 + 96 + 100 - 8 = 180
  • 88 + 100 - 8 = 180
  • 188-8=180
  • 180=180

Therefore, x = -8.

Given f(x) and g(x) = f(x) + k, use the graph to determine the value of k.
zalisa [80]
<h3>Answer: C) 4</h3>

All points on the blue curve f(x) are shifted up 4 units to get corresponding points on the red curve g(x). For example, the point (0,-3) moves up 4 units to (0,1).

g(x) = f(x)+k

g(x) = f(x)+4

The volume of a boys' basketball is 434 cubic inches. Dan would like to get a ball
Nataly_w [17]

Answer:

The correct answer is A. 9.4 inches.

Step-by-step explanation:

Given that the volume of a boys' basketball is 434 cubic inches, and Dan would like to get a ball with half the volume for his son, to determine what is the diameter of the ball that Dan will buy for his son, the following calculation has to be done, knowing that the volume of a sphere is four thirds multiplied by pi multiplied by the radius cubed:

4/3 x 3.14 x X ^ 3 = 434

4.186 x X ^ 3 = 434

X ^ 3 = 434 / 4.186

X = 3√ 103.662

X = 4.7

In turn, since the radius of a sphere is equal to half its diameter, the diameter of the basketball is 9.4 inches (4.7 x 2).
