Find the distance traveled in 35 seconds by an object traveling at a velocity of v(t) = 20 + 5cos(t) feet per second

1 answer:

8 0

$s(t)= \int\limits^{35}_0 {v(t)} \, dt \\ =\int\limits^{35}_0 {(20+5cos(t))} \, dt \\ =[20t+5sin(t)]^{35}_0 \\ =(20(35)+5sin(35))-(20(0)+5sin(0)) \\ =700+2.868=702.868 \, feet$

I need the answers with a explanation how you got it

AfilCa [17]

In the question, we are given the table of values below.

Using the graph plotter,

The slope(m) and the intercept(c) is given as (nearest tenth)

$m=14.0\text{ and c =}478.7$

This can be inserted into the equation of best fit below

$y=14.0x+478.7$

Also, the correlation coefficient is given as

$r=1.0$

The relationship is also strong and positive
