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.

HELLP PLSS<br><br><br>(-2 and 1/9) - (-4 and 1/3) = x<br><br><br>Find the value of x
dedylja [7]

Answer:

x = 20/9

Step-by-step explanation:

We want to write out all of the mixed fractions into improper fraction form. So -2 and 1/9 becomes -19/9 and -4 and 1/3 becomes -13/3. Then we get (-19/9) - (-13/3). The two minus signs together means a positive/plus sign, so we get -19/9 + 13/3. In order to add, we want the denominator to be the same. A common denominator could be 9, so -19/9 + 13(3)/3(3) = -19/9 + 39/9 = 20/9, which is our final answer
