Use the function below:

trig graph with points at 0, 2 and pi over 2, 5 and pi, 2 and 3 pi over 2, negative 1 and 2 pi, 2

what are the amplitude and midline?

amplitude: 2; midline: y = 3
amplitude: 1; midline: y = 3
amplitude: 2; midline: y = 1
amplitude: 3; midline: y = 2

answer: 180

step-by-step explanation:

12-2=10

20-2=18

10x18=180

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
