<span>The distance from Charlotte to Cincinnati is 365 miles and then from Cincinnati to Chicago is 247 miles.
So 365+247= 583
so it's 583 miles.</span>
Answer:
23.9
Step-by-step explanation:
His route from school to Rhianna's house to his house forms a triangle in which the sides are 7 miles and the hypotenuse is unknown. Solving using the Pythagorean theorem, we find the route from Rhianna's house back home is 7^2+7^2=x^2.
Rounding to the nearest tenth, we now know this route is 9.9 miles. Adding the total distances from each location, we get an answer of 7 + 7 + 9.9 = 23.9.
A rectangle with sides 15 and w has perimeter

We want this quantity to be at most 50, so it must be less than or equal to 50:

For the record, this implies that

So, the width can be at most 10.
Answer:

Step-by-step explanation:
We want an exponential function that goes through the two points (0, 8) and (2, 200).
Since a point is (0, 8), this means that y = 8 when x = 0. Therefore:

Simplify:

So we now have:

Likewise, the point (2, 200) tells us that y = 200 when x = 2. Therefore:

Solve for b. Dividing both sides by 8 yields:

Thus:

Hence, our exponential function is:
