A ball is thrown upward and outward from a height of 7 feet. The height of the ball, f(x), in feet, can be modeled by f(x)= -0.2x^2 + 1.2x + 7 where x is the ball's horizontal distance, in feet, from where it was thrown. Use this model to solve parts (a) through (c)

-14

step-by-step explanation:

2x2 – 2(x+4)

=2x2-2（5+4）

=4-2×9

=4-18

=-14

y=3n + 1

step-by-step explanation:

this is wrong because it says the second number is one less and i added one instead

they charge the same amount at 20 minutes.

step-by-step explanation:

option b  

step-by-step explanation:

we know that

the distance from point n to lm in the figure is equal to the distance of the perpendicular line to lm that passes through the point n

so

the distance is equal to the segment no

> given problem

therefore

the distance from point n to lm is equal to
