Answer:
Original equation:
y = a sin(b(θ -c)) + d
a = vertical dilation (stretch) of the amplitude
b = horizontal compression (shrink) of the period
c = horizontal shift (left/right)
d = vertical shift (up/down)
Your function is:
y = 3 sin(3θ + π) - 2
First, put it into the general from by factoring out the three in the argument of the sine:
y = 3 sin(3(θ + π/3)) - 2
a = vertical (amplitude) dilation = 3
b = horizontal (period) compression = 2π/period = 3
c = horizontal shift = π/3 to the left
d = vertical shift = -2
Answer:
24 GB
Step-by-step explanation:
Subtract the amount of money that was from the monthly plan:
75.99 - 59.99
= 16
Divide this by 4 to see how many extra GB were used:
16/4
= 4
This means that 4 GB were used beyond 20 GB.
This means 24 GB were used in total
3x-y-2=0 that’s the answer to this question
4*(1/2)^0 + 4*(1/2)^1 + 4*(1/2)^2 =
4 + 2 + 1 = 7
