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
7.6 grams of saturated fat times 4 Ounces
is 7.6x4, or 30.4
Y= 19.25x / which is the 3rd one
Subtract the tips from total earned:
400-253 = 147
Now Divide by hours worked:
147/28 = 5.25
Hourly rate is $5.25
u have to bacsically divide for all of them
