The voltage of the alternating current coming through an electrical outlet can be modeled by the function V(t) = 167 sin(110πt), where t is measured in seconds and V in volts. Find all times at which the voltage is at its maximum. (Let k be any integer.

for k =0, 1,2,3............

Step-by-step explanation:

From the function

For ,

...................(1)

That is, = 1...............(2)

Comparing equations (1) and (2)

For all positive integer values of k, i.e. k = 0, 1, 2, ........

d is correct

step-by-step explanation:

-4

step-by-step explanation:

do 6-10=

if u need it to be negative.
