<u>Given</u>:
The height of an object project upward is given by the polynomial
where t represents the time, in seconds.
We need to determine the height after t = 2.5 seconds.
<u>Height of an object:</u>
The height of an object after 2.5 seconds can be determined by substituting t=2.5 in the polynomial, we get;
Simplifying, we get;
Thus, the height of an object is 140 feet.
Answer:
-9
Step-by-step explanation:
2(n+6) -15 = 5n+18
2n + 12 - 15 = 5n + 18
2n - 3 = 5n + 18
2n = 5n + 21
-3n = 21
n = -9
Answer:
b
Step-by-step explanation:
4.75 rounds to 5 because the 7, 83 rounds to 80 because of the 3. 80*5=400
f(2.5) means x is equal to 2.5.
Replace x in the equation with 2.5 and solve:
6(2.5) + 1.5 = 15 + 1.5 = 16.5
f(2.5) = 16.5
