Answer:
Step-by-step explanation:
-0.59x+0.29=7.2
-0.59x+0.29-0.29=7.2-0.29
-0.59x=7.2
divide both sides by -0.59
x=−
11.7118644
that can be rounded to x= -11.7

Answer: 5 cos x
<u>Step-by-step explanation:</u>
y = sin x is y = cos x shifted to the right π/2 units.
y = 5 sin (x + π/2) is a shift to the left π/2 units (which results in cos x) and . an amplitude of 5.
--> y = 5 cos x
