Answer 3

can you show me your steps .@Lena772

Answer 4

@Lena772

Answer 5

yes i have (20+7cos(t))dt

Answer 6

ok

Answer 7

then

Answer 8

then v(t)=ds/dt

Answer 9

yes correct

Answer 10

then 20+7cost=[20t+7sint]
(t=15)

Answer 11

s(15)=20(15)+7sin15

Answer 12

very good

Answer 13

s(15)=300+7(0.2589)

Answer 14

s(15)=300+1.81

Answer 15

s(15)=301.81ft?
