Answer:
...so cos t = cot t can only happen when cos t is 0 or sin t is 1. (But sin t = 1 only happens when cos t = 0, so cos t = 0 is enough.)
arccos(0) is pi/2, plus or minus any multiple of pi.
Step-by-step explanation:
cotθ = cosθ
cosθ/sinθ = cosθ
sinθ = 1
θ = π/2
pi also = to 3.14 etc.
Answer: C
Step-by-step explanation:
You have to multiply the x by 75 to get the y value
1 x 75 = 75
2 x 75 = 150
3 x 75 = 225
And so on...
So we know that the answer is 5.1 because the 77.0 you could add and get 22
Dividing is the opposite of Multiplying.
If you multiply 9 * 1 = 9.
So if you Divide N by 9 the answer would be 1.
I hope this helped. ^_^
