Answer:

Exponential model best fits this situation.

Step-by-step explanation:

Given : Karl has $400 in a savings account. The interest rate is 10%, compounded annually.

We have to determine which type of model best fits this situation.

Since, interest is calculated compounded

Using formula for compounded  interest , we have,

A=P(1+r)^n

Where P is principal amount

n is time period

r is interest rate

We are given P = $ 400

and r = 10 % = 0.10

Substitute, we have,

A=400(1+0.10)^n

A=400(1.10)^n

Now this is an equation of the form a^x which is exponential function.

So, exponential model best fits this situation.

dimaraw [331]

Answer:

  • <u>14.4 mile</u>²

Explanation:

1. By driving 6 miles each, the cars will be 6 miles + 6 miles = 12 miles appart.

2. When one car stops and the other car makes a 90° left-hand turn and drive 8 miles, you can model the situation with a right triangle, where one leg is 12 miles, the other leg is 8 miles, and the hypotenuse is the distance that separates the cars.

Hence, you must use Pythagoras to find that distance.

3. Pythagoras

  • hypotenuse² = leg₁² + leg₂²

  • hypotenuse = (12 mile)² + (8 mile)² = 144 mile² + 64 mile² = 208 mile²

  • hypotenuse=\sqrt{208mile^2}=14.4mile^2, which is rounded to the neartest tenth of a mile.
