Choose the letter of the equation for the graph.
a. y = sin(x –T/2) + 1
b. y = cos(x +T/2) + 1
c. y = cos(x - 1/2) - 1
d. y = cos(x - 1) - 2
e. y = sin(x - 7) - 2
Kla

the answer is d) y = cos(x - Pi) - 2

Step-by-step explanation:

you can see that on the graph that os must be -2.. so you can move it for 2 up

than you have to take in count that (x - Pi) so you move your graph for Pi to the left

and than you have to recognize the function.. if it goes through 0 is sin if not is cos

hello from mrbilldoesmath!

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²
