Answer: A
Step-by-step explanation:
ok, so amplitude is the A term, basically the first thing in the equation (1/2) but can’t be negative. the phase shift is in the parentheses, it’s that pi/2, (or 1/2 pi). the period is 1/2 pi since the formula is 2pi/4. (i think that’s right i’m not 100 percent sure

Answer:
C. 72 sorry if its wrong
Step-by-step explanation:
trapezoid formula : A= 1/2h(B+b)
plug in:
A= 1/2×6(10+14)
A= 3(24)
A= 72
As i said before put the center instead of (h,k) in the general formula and put r=1
so (x-(-2))^2 + (y-(-5)^2 = 1
(x+2)^2 + (y+5)^2 = 1
A= -6(-2) < -10
12 < -10
NOT TRUE
B= -2(-2) > -3
4 > -3
TRUE
C= -2/4 < 0
-1/2 < 0
TRUE
D= -4 < (-2)-5
-4 < -7
TRUE
So the answer is A
