What are the amplitude, period, and midline of f(x) = -4 cos(2x - y) + 3 1) Amplitude: -4; period: pie/2 ; midline: y = -4

2) Amplitude: -4; period: pie; midline: y = -4

3) Amplitude: 4; period: pie; midline: y = 3

4)
Amplitude: 4; period: pie/2 ; midline: y = 3

d) the triangle is a right triangle 60 squared +144 squared= 156 squared

step-by-step explanation:

156 squared is the hypothenuse

so 156= c

12r - 8 - 12

you have to combine like terms. below i have bolded the like terms:

12r - 8 - 12

together it combines to:

12r - 20

hope this !
