Alex73 [517]3 years ago
6 0
Part A:  Charlie's answer is incorrect
In step 2 of Charlie's answer he subtracted 5 from each side.  Since 5x is multiplication, he must DIVIDE each side by 5 to get x by itself.  The problem should have worked out like this...

Step 1:  5x = 30
Step 2:  x = 30/5
Step 3:  x = 6

Part B:  There is only 1 solution for this problem.

What are the period and amplitude of the function?
lianna [129]

ANSWER

Period: 2π , amplitude: 4

EXPLANATION

The graphed function is

y =  4\cos(x)

The amplitude of this function is

|4|  = 4

The period is 2π because there is no phase shift hence the period is still equal to the parent function.

Period: 2π , amplitude: 4
