Answer:
9 feet
Step-by-step explanation:
The height of the ball in feet is given by the polynomial:
where t is the time in seconds.
After 3 seconds, t = 3:
The height of the ball after 3 seconds is 9 feet.
Answer:
Domain={-2,2,3,5}
Range={-3,1,7,12}
Step-by-step explanation:
The given ordered pairs are (5,12)(3,-3),(-2,7)(2,12)(5,1).
The domain refers to the set of all the first coordinates(x-values).
Domain={-2,2,3,5}
The range refers to the set of all the second coordinates (y-values).
Range={-3,1,7,12}
Note that, we do not repeat elements in a set.
Do not list the 5 in the domain twice.
The same applies to the 12 in the range
9(7 + 8) = (9 x 7) + (9 x 8) = 63 + 72 = 135
