If the function is:
y=a cos( bx+c), or y=a sin(x+c)
then the period is T= 2π/b and if T=2:
2=2π/b
b=2π/2=π
Answer: B) y=3 cos πx
Answer:
arc VW = 66°
Step-by-step explanation:
The inscribed angle WXY is half the measure of its intercepted arc WY, so
WY = 2 × 57° = 114°
Arc YX = 180° ( semi- circle ) , then
VW = YX - WY = 180° - 114° = 66°
Answer:
C
Explanation:
A: 2 in. by 2 in. by 1 in. = 4 cubic inches
B: 1 in. by 1 in. by 1 in. = 1 cubic inches
C: 2 in. by 1.5 in. by 0.5 in. = 1.5 cubic inches
D: 3 in. by 0.5 in. by 1.5 in. = 2.25 cubic inches
Therefore, the answer is C.
Answer:
true
