(a) Find the height of the ball (in feet) above the ground 2 s after its released.
That's just h(2)
h(2) = -16(2²) + 80(2) + 4 = -64 + 160 + 4 = 100
Answer: 100 feet
(b) Find the height of the ball (in feet) above the ground 4 s after its released.
That's just h(4)
h(4) = -16(4²) + 80(4) + 4 = -256 + 320 + 4 = 68
Answer: 68 feet
We know that 17 over 25 is a fraction. To convert to decimal we have to do - <span>Numerator / Denominator.
</span>
Numerator: We call the top number the Numerator, it is the number at the top of the fraction you have.
Denominator: We call the bottom number the Denominator, it is the whole number that is at the bottom, it is the number that is divided into.
<span>
To solve this problem we have to set up long division.
17 / 25 = 0.68
0.68 is a terminating decimal. </span>
<span>For this case we have the following expression:
</span>
<span> We are going to make the following change of variables:
</span>
<span>Rewriting the expression we have:
</span>
<span>Factoring the expression we have:
</span>
<span>Canceling similar terms we have:
</span>
<span>Returning the change we have:
</span>
<span> The resctrictions of the function are those that make the denominator equal to zero.
We have then:
</span>

The restrictions are: </span>
Answer:
p=2
Step-by-step explanation:
-7p = -3p - 8
Add 3p to each side
-7p+3p = -3p+3p - 8
-4p = -8
Divide each side by -4
-4p/-4 = -8/-4
p = 2
