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 is 4/7
You divide the length of C'D' over the length of CD
C'D'/CD = 8/14 = 4/7
The scale factor is smaller than 1, so C'D' is shorter than CD
Answer:
Decimal: 0.33
Percent: 33.33
Step-by-step explanation:
First 3/1 =0.33333333333 and so on
so put first to numbers 0.33
Second move decimal to right 2 places.
0.33 -> 03.3-> 33.0 or 33
There you go
Answer:
b. 4,264,650
Step-by-step explanation:
(9 * 9 * 9 * 9) * (26 * 25)
Efficiency = (output)/(input).
This could also be written as
efficiency= output/(output+losses)
or
eff=(input-losses)/input
