ANSWER

$h= 2 \cos(\pi(t + \frac{1}{2} )) + 5$

EXPLANATION

The given equation that models the height is

$h(x) = - 2 \sin(\pi(t + \frac{1}{2} )) + 5$

This is sine a sine function that is reflected in the x-axis.

This function will coincide with the cosine function with the same amplitude, period, phase shift and vertical translation.

The function that can also model this height is

$h= 2 \cos(\pi(t + \frac{1}{2} )) + 5$

The last choice is correct.

An oil tank has a capacity of 45 gallons. At the beginning of October it is 80% full. At the end of October it is 1/3 full. How

Yakvenalex [24]

Capacity of the tank = 45 gallon
At the beginning of Oct., amount of oil in the tank = 45*0.8 = 36 gallons
At the end of Oct., amount of oil in the tank = 45*1/3 = 15 gallons
So, amount of oil used during Oct = (36-15) = 21 gallons
