Which formula gives the x-coordinates of the maximum values for y = cos(x)?

ks for any integer k
kr fork-0,+2 +4
2
for any positive integer k
2 for k=0,12,14...

the answer is d. 75%

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!

the answer is a) y= 2 csc [0.5 (x+pi/2)]-1
