Answer:
2 19/21, 61/21
Step-by-step explanation:
First, lets make the denimonators, "3 and 7" common. 3 and 7 are prime numbers, so the common denonminator is "21".
For 7/3, multiply by "7/7" and for 4/7 multiply by "3/3".
49/21 + 12/21
Add.
61/21
61 is a prime number so this answer will be your final answer.
(unless you have to put it as a mixed number which would be 2 19/21)

Step-by-step explanation:
Answer:
- maximum height: 498 ft
- distance from point of release: 70 ft
Step-by-step explanation:
A graphing calculator can show the answers to these questions.
___
For quadratic ax²+bx+c, the x-value of the vertex is ...
x = -b/(2a)
For the given expression, the vertex is ...
x = -14/(2(-0.1)) = 70
The distance from the point of release to the point of maximum height is 70 feet.
__
The height of the ball at that point is ...
f(70) = (-0.1·70 +14)70 +8 = 7·70 +8 = 498 . . . . feet
The maximum height is 498 feet.
