A = P(1+r)^t where P is the principal (starting) amount, r is the rate of interest, and t is time. Knowing this, plug in your values:

A = 3,000(1+0.025)^4 < this is what your equation should look like. Once you enter this into a calculator, you should get an answer of $3,311.438672. Round, and you'll be finished.

Answer: The final balance on the account will be $3,311.44

Valerie is taking a road trip over spring break. At 4:30 p.m. she looks down at her speedometer and notices that she is going 45

hammer [34]

Answer:

b. 4:35 p.m

Step-by-step explanation:

Her speed in t minutes after 4:30 p.m. is modeled by the following equation:

$v(t) = v(0) + at$

In which v(0) is her speed at 4:30 pm and a is the acceleration.

At 4:30 p.m. she looks down at her speedometer and notices that she is going 45 mph.

This means that $v(0) = 45$

Ten minutes later she looks down at the speedometer again and notices that she is going 55 mph.

This means that $v(10) = 55$

$v(t) = v(0) + at$

$55 = 45 + 10a$

$10a = 10$

$a = 1$

$v(t) = 45 + t$

When was she moving exactly 50 mph?

This is t minutes after 4:30 p.m.

t is found when v(t) = 50. So

$v(t) = 45 + t$

$50 = 45 + t$

$t = 5$

5 minutes after 4:30 p.m. is 4:35 p.m.

So the correct answer is:

b. 4:35 p.m
