Answer:
7)no
Step-by-step explanation:
When you plug in the numbers
3(2)-0=-6
6-0=6
6 does not = -6
Answer:
3/π Hz
Step-by-step explanation:
Recall that for a cos function in the form
y = A cos Bx
period = 2π / B
frequency = 1/period = B/2π
Given y = -5 cos 6x
A = -5 and B = 6
frequency,
= B / 2π
= 6 / 2π
= 3/π
Step-by-step explanation:
Given
Radius (r) = 3 inch
Circumference
= 2πr
= 2 * 3.14 * 3
= 18.84 inch
Now
Area
= π r²
= 3.14 * 3 ²
= 3.14 * 9
= 28.26 inch²
