Step-by-step explanation:

h(t) = -16t² + 64t + 32

When h(t) = 80, -16t² + 64t + 32 = 80.

=> 16t² - 64t + 48 = 0

=> t² - 4t + 3 = 0

=> (t - 1)(t - 3) = 0

=> t = 1 or t = 3.

Hence the difference between the times is 2 seconds. (B)

Tyler used 1 1/4 gallons of paint to paint 5/7 of a fence. How many gallons will it take to paint the whole fence? Explain or sh
mina [271]

For this case we have missing \frac {2} {7}of fence to be painted.

To paint \frac {5} {7} of fence we used:

1 \frac {1} {4} = \frac {4 * 1 + 1} {4} = \frac {5} {4}gallons of paint. So, we make a rule of three:

\frac {5} {4} ------------> \frac {5} {7}\\x --------------------------> \frac {2} {7}

Where the variable "x" represents the gallons of paint needed to paint the missing fence

x = \frac {\frac {2} {7} * \frac {5} {4}} {\frac {5} {7}}\\x = \frac {70} {140} = \frac {1} {2} = 0.5

Thus, 0.5 gallons of paint is missing for the missing fence.

Answer

0.5 gallons
