Answer:
The height of the football after 4 seconds is 80 feet.
Step-by-step explanation:
You know that the height (in feet) of punted football is a function of the time the ball is in the air and it is defined by:
h(t) = -7*t²+48*t
To calculate the height of the ball after 4 seconds, you must replace the time t by the time of 4 seconds:
h(4) = -7*4²+48*4
Solving, you get:
h(4) = -7*16+48*4
h(4) = -112+192
h(4)= 80
<u><em>The height of the football after 4 seconds is 80 feet.</em></u>
(4 - -2) / (9 - 5) = 6/4 or 3/2
Answer:
-1
Step-by-step explanation:
f of 3 is the same thing of f of x which is y. The questions is saying if x is equal to 3, then what is y. x is represented by domain and y is represented by range. If you find x which is 3 in the domain, then the arrow points to negative 1 in the range circle.
Answer:
Future Value= $5,886.13
Step-by-step explanation:
Giving the following information:
Initial investment (PV)= $5,425
Number of periods (n)= 1 year
Interest rate (i)= 8.5% = 0.085
<u>To calculate the future value after one year, we need to use the following formula:</u>
<u></u>
FV= PV*(1+i)^n
FV= 5,425*(1.085^1)
FV= $5,886.13
