A ball is shot from a cannon into the air with an upward velocity of 65 ft/sec. The equation that gives the height (h) of 2
the ball at any time (t) is: h(t)= -14t +65t+1.75.
You must show your work.
● Find the maximum height attained by the ball.
● What time was the maximum height achieved?.
● How high was the ball off of the ground when it was shot? ● How far did the ball travel before it hit the ground?
● Graph this quadratic

6, 10

9, -13

12, -21

18, -23

step-by-step explanation:

you just add 6 to the x-coordinate and subtract 10 from the y-coordinate.

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.

i believe your answer is 99.7% of 7-year-old children are between 46.6 inches and 49.5 inches tall.

i believe it's a.

i'm not sure on this one, most likely correct.
