V(t) = dy/dt = 40 - 32t
ai). average velocity = (v(0.5) - v(0))/(0.5 - 0) = ((40 - 32(0.5)) - (40 - 32(0)))/0.5 = (40 - 16 - 40)/0.5 = -16/0.5 = -32m / s
ii). average velocity = (v(0.1) - v(0))/(0.1 - 0) = ((40 - 32(0.1)) - (40 - 32(0)))/0.1 = (40 - 3.2 - 40)/0.1 = -3.2/0.1 = -32m / s
iii). average velocity = (v(0.05) - v(0))/(0.05 - 0) = ((40 - 32(0.05)) - (40 - 32(0)))/0.05 = (40 - 1.6 - 40)/0.05 = -1.6/0.05 = -32m / s
Answer:
TV #3
Step-by-step explanation:
The others cost more.
Answer:
its A
Step-by-step explanation:
i did it on khan academy and it's the table in the questions
Lets factor 8x^2 - 10x - 25
= 8x^2 -20x + 10x - 25
= 4x(2x - 5) + 5(2x - 5) 2x-5 is common to both parts so factors are:-
= (4x + 5)(2x - 5)
So its C
