A body is moving along a straight line with a velocity which varies according to the equation v = 9 t2 + 2t, where v is in feet

kaheart [24]

V(t) = 9t² + 2t
To find a function for distance as a function of time:

Using Calculus:
Take the integral of V(t)
This means find the anti-derivative (if v(t) is the derivative of d(t), what must d(t) be?)
d (t) = (1/3)*9* t ²⁺¹ + (1/2) * 2 * t¹⁺¹
d(t) = 3t³ + t² + C

Answer is B) 3t³ + t² + C.

Why did we add C at the end? The velocity function doesn't tell us anything about our initial distance, so we add C to account for wherever we started at t=0. This is also known as our Constant of Integration

Nolan Walker decided to buy a used snowmobile since his credit union was offering such low interest rates. He borrowed $2,700 at

stealth61 [152]

Using the formula for simple interest, it is found that he paid $119.87 in interest.

The<u> simple interest formula</u> is given by:

$E = PIt$

E is the amount of interest earned.
P is the principal(the amount of money invested).
I is the interest rate(yearly, as a decimal).
t is the time, in years.

In this problem:

Borrowed $2,700, thus $P = 2700$
Interest rate of 3.5%, thus $I = 0.035$
From December 26, 2019 to February 21, 2021, there were 423 days, thus the time in years is $t = \frac{423}{365} = 1.2685$
