Answer:
b.)
Step-by-step explanation:
I think the first one is correct. Since “three less than z squared” insinuate that the value is 3 units less than the value z^2
Answer:
-2pi/3
Step-by-step explanation:
y = 2 cos 3(x + 2π∕3) +1
y = A sin(B(x + C)) + D
amplitude is A
period is 2π/B
phase shift is C (positive is to the left)
vertical shift is D
We have a shift to the left of 2 pi /3
Suppose the length is 7x, the width is then 3x
7x*3x=525
21x²=525
x²=25
x=5
so the length is 7*5=35, and the width is 3*5=15
Answer:
0
Step-by-step explanation:
It may say combine, but it`s subtraction soooo it`s 0.
