Answer:

s(t) = \frac{t^4}{12} - \frac{4t^3}{3} + \frac{7t^2}{2} + v_0t + s_0

Step-by-step explanation:

We can first integrate the acceleration to find the velocity with respect to time

v(t) = \int {a(t)} \, dt= \int {t^2 - 8t + 7} \, dt = \frac{t^3}{3} - 4t^2 + 7t +v_0

Then we can integrate the velocity to find the position of the particle with respect to time:

s(t) = \int {v(t)} \, dt = \int {(\frac{t^3}{3} - 4t^2 +7t + v_0)} \, dt = \frac{t^4}{12} - \frac{4t^3}{3} + \frac{7t^2}{2} + v_0t + s_0

How does f(x) = 9x change over the interval from x = 4 to x = 5?
mr_godi [17]

Answer: A

put x = 3 into f(x)=6x and you get f(x) = 18

Put x = 4 into f(x) and you get f(x) = 24

Subtract those two. 24 - 18 = 6

Also, f(x) = 6x it will always be 6 away from the next x you put into the equasion.

Or better said, it will be 6 more from 6x, because you are changing the x to X+1, hence,

6(x+1) = 6x + 6.

+6, it increases.

In angle ABC, ray BX is in the interior of the angle, the measure of angle ABX is 12 more than 4 times the measure of angle CBX,
Alex73 [517]
To start you should represent CBX as x. so, an equation would be                       92 = x + 4x + 12. This is the equation so, 92 is the total angle, and the 12x + 4 is the ABX part. So, once you solve the problem you should get CBX=76 and ABX=16
