Remember that the velocity as a function of time is the derivative of the position as a function of time.
To solve this we are going to take the derivative of our position function $s=24t+3t^2-t^3$ . To do that er are going to apply the power rule of calculus: $\frac{dy}{dx} x^n=nx^{n-1}$

$\frac{dy}{dx} 24t+\frac{dy}{dx}3t^2-\frac{dy}{dx}t^3$
$24+2(3)t-3t^2$
$v=24+6t-3t^2$

We can conclude that the correct answer is: <span>B. V = 24 + 6t - 3t2</span>

marianne buys 16 bags of potting soil that comes in 5/8 lb. bags. how many pounds of potting soil foes she has.

andriy [413]

One bag of soil is 5/8 pounds.
you have 16 of them.
just multiply 16 by 5/8.
you could just type it into your calculator, or you could do it the long way:
$16 * \frac{5}{8} \\ \frac{16*5}{8} \\ \frac{8*2*5}{8} \\ 2*5\\10$

she has 10 pounds of potting soil.
