Answer:
y=9sin(theta)
Step-by-step explanation:
I'm assuming it's in degrees. The amplitude of the graph is 9, and so you multiply the base sine equation y=sin(theta) by nine. I don't see any shifts and the period remains at 2pi (360 degrees) so I don't think anything else is really needed.

Step-by-step explanation:
Answer:
63 students said yes.
Step-by-step explanation:
105/5= 21
21*3= 63
8x + 3y = 20.50
-
4x+5y=22.50
=
4x-2y=-2, so you have to divide each number by 2, then
2x-y=-1, so
-y=-1-2x /-1, y=1+2x, then replace it with one original equation like the first one for instance:
8x+3(1+2x)=20.50, then
8x+3+6x=20.50, then
14x=20.50-3
14x=17.5
x=1.25, then solve y:\
y=1+2*(1.25)
y=1+2.5
y=3.5,
So answer is x=1.25, and y=3.5
Answer:
130
Step-by-step explanation:
We need to keep adding 13 together until we have done this 10 times :)
10%: 13
20%: 26
30%: 39
40%: 52
50%: 65
60%: 78
70%: 91
80%: 104
90%: 117
100%: 130
