For what value of c is the function one-to-one? {(1, 2), (2, 3), (3, 5), (4, 7), (5, 11), (6, c)}

5   1/4   miles per hour

step-by-step explanation:

15   3/4 / 3 = 5   1/4

3 is greater then both of those numbers

$54.99

step-by-step explanation:

$54.99 includes 500 min. if she does not exceed 500 min then her bill is $54.99

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus
