Answer:

(C) 3 feet

Step-by-step explanation:

We have a function of f(x) here. When Sarina throws the ball, it has been 0 seconds since she threw it.

Since x represents the amount of seconds, we can find the height of the ball (f(x)) by substituting x in as 0.

-0^2 - 0 + 3

0 squared is 0, 0 minus zero is 0, and 0+3 = 3, so

f(x) = 3

Meaning that when Sarina threw the ball, it's height was 3 feet.

Hope this helped!

What is the solution to the inequality 0.8x+20<1.2x−40?
LuckyWell [14K]

Answer:x=150

Step-by-step explanation:

Step 1: Subtract 1.2x from both sides.

0.8x+20−1.2x=1.2x−40−1.2x

−0.4x+20=−40

Step 2: Subtract 20 from both sides.

−0.4x+20−20=−40−20

−0.4x=−60

Step 3: Divide both sides by -0.4.

−0.4x

−0.4

=

−60

−0.4

A carousel is an amusement ride consisting of a rotating...
Whitepunk [10]
To answer this question you will use the formula for circumference of a circle to find how far around one revolution is.

C = pi x d
     3.14 x 32
C = 100.48 feet

Multiply the distance around one time by 4.3 to get the distance traveled in one revolution and then multiply it by 3 for the 3 minutes.

100.48 x 4.3 x 3 = 1296.19 feet
This is approximate and is closest to answer choice D.
