A car uses 5 gallons of gasoline to travel 97.5 miles. At this rate, how many miles can the car travel using 13 gallons of gasoline?

Answers

Answer:

a

Step-by-step explanation:

Answer:

253.5 miles

Step-by-step explanation:

This problem can be solved by using the concept of "ratios" and "proportions."

Step 1: Check for the "known" and "unknown" variables.

The known variables are: 5 gallons, 97.5 miles and 13 gallons while the unknown variable is the "number of miles" the car can travel using 13 gallons.

Step 2: It's time to plug the values into the proportion.

5 gallons/ 97.5 miles = 13 gallons/ x miles

Step 3: Solve the proportion.

 5/97.5 = 13/x =   ⇒ 5x = 1,267.5 ⇒ x = 253.5 miles

Select the slope of the line

Answers

Answer:

Undefined.

Step-by-step explanation:

The line given on the graph is vertical.

All vertical lines have an undefined slope.

This is because that it has no horizontal (run) change.

If you used the slope formula for the points, the denominator of the fraction will be a zero, and and you cannot divide by zero.

Hope this helps!

A serval, an African wildcat, leaps high above the ground to pounce on its prey. The height of the serval above the ground in relation to the horizontal distance it travels, both measured in feet, is modeled by the given function.

What does the domain of the function represent in this situation?

A.
the horizontal distance the serval travels during its leap
B.
the height of the serval along the path of its leap
C.
the horizontal distance at which the serval reaches its maximum height above the ground
D.
the maximum height the serval reaches above the ground

Answers

Answer:

A. the horizontal distance the serval travels during its leap

Step-by-step explanation:

In this situation, the height along the path that the serval leaps is represented on the y-axis (range value), as against its corresponding horizontal distance on the y-axis (domain value) during the course of its leap.

Therefore, in this situation, the the horizontal distance the serval travels during its leap is the domain of the function.
