Replace cos^2(θ) with 1-sin^2(θ), and cot(θ) with cos(θ)/sin(θ).
cos^2(θ)cot^2(θ) = cot^2(θ) - cos^2(θ)
(1 -sin^2(θ))cot^2(θ) = . . . . . replace cos^2 with 1-sin^2
cot^2(θ) -sin^2(θ)·cos^2(θ)/sin^2(θ) = . . . . . replace cot with cos/sin
cot^2(θ) -cos^2(θ) = cot^2(θ) -cos^2(θ) . . . as desired
Answer:
The slope is 2.
Step-by-step explanation:
In order to find the slope of the line, we need to start by using the points in the slope formula.
m(slope) = (y2 - y1)/(x2 - x1)
m = (20 - 10)/(6 - 1)
m = 10/5
m = 2
So the slope of this line would be 2
Answer: The estimated value for population mean rating based on these ten sampled ratings is 7.3 .
Step-by-step explanation:
Given : A random sample of size ten produced the following ratings in the computer games rating example in the last lesson:
12, 5, 2, 4, 1, 4, 18, 10, 1, 16.
Let x denotes any value in the above data.

We know that the sample mean
is the best estimate to the population mean
.
Sample mean=
Here , n= 10


Therefore , the estimated value for population mean rating based on these ten sampled ratings= 7.3
Answer:
i think b, because when an ucharged object touches/combines with another object that's uncharged.. the uncharged object will become charged. so by bringing a charged object into contact with an uncharged object, some electrons will migrate to even out the charge on both objects.
Step-by-step explanation:
hope this helps!
