Carlos operates a helicopter. carlos decides to measure the rotational velocity of the helicopter blades. what would be an appropriate unit for carlos's purpose? a.) meters/secondb.) degrees/square secondc.) degrees/secondd.) meters/square second

(C) degrees/second

Explanation:

The rotational velocity must be a rate of units of rotation per unit of time. Rotations can be measured in "revolutions", "cycles", or "angle of rotation in degrees "

The only choice appropriately matching the above thought is (C) where the angle in degrees represents to the rotation count, per unit of time, i.e., 1 second.

-10i^2-4i

step-by-step explanation:

evaluate for p=2,q=5i

(2−4)(2+5i)i

(2−4)(2+5i)i

=−10i2−4i

correct answer:

b.(19,-2)
