As, cosecx, secx and cotx are just the reciprocals of sinx, cosx and tanx, when you multiply each corresponding pair you just get 1. This results in 1*1*1 giving a final answer of 1.
Answer:
7 to 8 hours
Step-by-step explanation:
1 * 4 = 4
5 / 6 * 4 = 20 / 6 = 3 2/6 or 3 1/3
4 + 3 1/3 = 7 1/3
Answer:
A.
Step-by-step explanation:
Answer:
D. v=<20, 52>
Step-by-step explanation:
Vector u can be written in component form by subtracting its initial point from its terminal point:
u = (5, -4) -(15, 22) = <-10, -26>
We are told that v = -2u, so ...
v = -2<-10, -26> = <20, 52>
_____
Multiplying a vector by -1 reverses its direction; multiplying it by some factor k changes its magnitude by a factor of k. To reverse the direction and double the magnitude, we can multiply u by -2.
