Answer:
Step-by-step explanation:
if (x,y) is any point on unit circle then
x²+y²=1²
x²+y²=1
(3/4)²+y²=1
9/16+y²=1
y²=1-9/16=(16-9)/16=7/16
y=±√7/16
Answer:
f(1) = 81
Step-by-step explanation:
given is f(n + 1) = 1/3f(n)
f(3) = 9
ayou need to find f(0) before you can answer what is f(1).
Just start by applying for...
n=0
f(0+1) = 1/3 * f(0)
f(1) = 1/3 * f(0)
n=1
f(1+1) = 1/3 * 1/3*f(0)
f(2) = 1/9 * f(0)
n=2
f(2+1) = 1/3 * 1/9* f(0)
f(3) = 1/27 * f(0)
But it is given that f(3) = 9 so substitute this in the line above to calculate the value of f(0)....
9 = 1/27 * f(0)
Multiply left and right of the = sing by 27 gives
f(0) = 27 * 9
f(0) = 243
We already know this next line because we started with n=0
f(1) = 1/3 * f(0)
Substitute f(0) = 243 in the line above to finally calculate the value of f(1).
f(1) = 1/3 * 243
f(1) = 81
It is D.) 237 and 2/3... glad I was able to help!
This problem is basically asking what 960x3.25 is, since 6 hours is one fourth of a day.
960x3.25=3120 watt-hours.
3120 watt-hours is your answer.
