22. the time constant of an rc circuit where the capacitance
circuit where the capacitance is 3 f and the resistance is 10 ohms is:
a. 13.0 seconds
c. 3.0 seconds
b. 30.0 seconds
d. 3.3 seconds

Factor completely. 4p^2 + 36p + 81 express the answer in the form (ap + b)^2

Ijust need these 2 questions answered (the second pic is just confirmation i'm not confident in that answer)

One of the complementary angles is 4 degrees mor than the other. find the angles (recall that complementary angles are angles whose sum is 90 degrees.) which of the following can not be used to solve the problem if x represents one of the angles? a. 2x-4=90 b. 2x+4=90 c. x+4=90
