Answer:
5s^2 - 30st - 7t^2
Step-by-step explanation:
Answer:
velocity v(t) = -2cos(t)+t+2
position s(t) =
average of position from 2 to 5 = 17.666
Step-by-step explanation:
velocity is anti-derivative/integral of acceleration
= -2cos(t)+t+C
v(0) = 0
0 = -2cos(0)+0+C = -2 +C; C = 2
v(t) = -2cos(t)+t+2
position is anti-derivative of velocity
=
s(0) = 3
3 = -2sin(0) + 0 + 0+ C
3 = C
s(t) =
average value of a function of a domain [a, b] is given by the equation
average of position from t = 2 to t = 5
= 2cos(5)+125/6+25+15 - 2cos(2) - 8/6 -4 + 6
=52.999 (use a calculator)
52.999/3 = 17.666
It would be 41*10^2. I get the answer (when it's a short number) by multiplying 10 by10 and keep going on until I think I found the number and multiply it by that number. 10*10=100*41=4100
Hope this helps! :)
