Answer:

B. The slope of the line is 2. This means that Jan runs 2 laps every minute.

Step-by-step explanation:

This is a proportional relationship as the line passes through the origin.

<u>Therefore you can use one point to determine the slope, (2, 4):</u>

m = y/x = 4/2 = 2

The slope is 2. It is a 2 laps per minute.

On a clear day you can see about 25.2 miles from the upper observation platform of the Eiffel tower in Paris. Using the formula

Answer:

D. 914 feet

Step-by-step explanation:

We are given the distance that a person can see on a clear day from the upper observation platform of the Eiffel tower in Paris. We are then required to estimate the height of the upper observation platform using the formula;

$d=\frac{5}{6}\sqrt{h}$

Where d is the distance and h the height of the upper observation platform. The first step would be to solve for h, that is make h the subject of the formula in the above equation;

We multiply both sides of the equation by the reciprocal of 5/6 which is 6/5;

$\sqrt{h}=\frac{6}{5}d$
