A jet ski can go 50 miles using one gallon of gas. About how many gallons of gas will be used to go 150 kilometers?
vichka [17]

Answer: 1.86 gallons

Step-by-step explanation:

A jet ski can go 50 miles using one gallon of gas. To find the number of gallons needed for 150 kilometers, first convert kilometers to miles:

1 mile = 1.60934 kilometers

150 kilometers will be:

= 150 / 1.60934

= 93.2059 miles

If a jet ski can go 50 miles on one gallon, the number of gallons required for the above is:

= 93.2059 / 50

= 1.86 gallons

What is the range of the function y = x^2?
user100 [1]

Answer:

The range is y≥0

Step-by-step explanation:

The shape of this graph is a parabola

You may see this by using the Desmos calculator and typing y=x^2 if you would like to visualize.

(a) The function y = x^2 simply takes whatever number you feed it (x) and outputs x squared.

For example

y = (2)^2=4

y = (3)^2 = 9

(b) To graph x^2 simply make a table of values and plug in 0 -> however high you would like to go ( usually to 5 or so is fine but you could go to infinity).

Example

      y = x^2

                 Y    |     X

                ________

                 2      |   4  

                 3     |   9

                 4    |    16

In this case the function's range is y≥0 because all y values will be greater than or equal to 0.

If you are wanting to learn how to specifically graph this you can look up (Graphing y = x²) if my quick graphing explanation back at mark (b) does not help.
