Answer:
a
Step-by-step explanation:
The equation you use to find this is A=P(1+r/n)^nt
P is your initial amount
r is the rate in a decimal
n is the number of times compounded per year
T is the number of years
We can plug all of these things into the equation to get A=4500(1+.13/1)^1(7)
this simplifies down to A=4500(1.13)^7. If you put this into your calculator, you get 10586.724662
since it is in dollars, round to the nearest cent to get $10,586.72
Answer:
(a) 4 seconds
Step-by-step explanation:
The given point (4, 0) on the parabola tells you the answer to the question: the coin was in the air 4 seconds before its height is 0. It is no longer in the air at that point.

<em>Additional comment</em>
In order to match the rest of the problem statement, the first given x-intercept must be (-2, 0).
<span>(300 ft/2.92 sec)(1 mi/ 5280 ft)(3600 sec/1 hour)
= {300 x 1 x 3600 miles)/(2.92 x 5280 x 1 hour)
</span><span>= 91080000 miles/15417.6 hours
= 70.05 mph </span>
the answer is 52°
use the laws of trig
its a right triangle, so cotan 9/7 is 52°
