Answer:
A & B
Step-by-step explanation:
A) V = pi×r²×h
= 3.142 × 8² × 5 = 1005.44 cm³
B) V = ⅓ × 18×16 × 12 = 1152 cm³
C) V = ½×5×3 × 7 = 52.5 cm³
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.
