Please help...(will report spam) What is the graph of one cycle of a sine curve with amplitude 5, period pi, and a>0?

What is an equation for the sine curve in the form y=asinb0?

a. y=2sin50
b. y=5sinpi0
c. y=5sin20
d. y=5sin1/2 0

step-by-step explanation:

what grade level is this? need to know so i can look in my old textbooks!

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°

can you make your screen more see able?

then i might be able to .
