Answer:</h3>
![\frac{1}{9}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B9%7D)
<h3>
Step-by-step explanation:</h3>
We know that
, so substitute that into the equation. ![y=3^{-2}](https://tex.z-dn.net/?f=y%3D3%5E%7B-2%7D)
With negative powers, instead of making the result negative, you divide one by it. Mathematically speaking,
. This makes our equation: ![y=\frac{1}{3^2}](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B1%7D%7B3%5E2%7D)
Finally, simplify the exponent. ![y=\frac{1}{9}](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B1%7D%7B9%7D)
Answer:
12.5
Step-by-step explanation:
(3+8)/2 = 5.5
5.5 + 7 = 12.5
Answer:
A)6, 2, -2,-6
Step-by-step explanation:
a(n) = a +(n-1)d
a(n) = a +dn-d
a(n) = a-d + dn
a(n) = 10 - 4n
So d=-4
to get a: (a-d)=10
a=10-4=6
The first four terms:
a(1) = 6 +(1-1)-4=6
a(2) = 6 +(2-1)-4=2
a(3) = 6 +(3-1)-4=-2
a(4) = 6 +(4-1)-4=-6
it will be A

Answer:
it takes about 2.79 seconds for the object to hit the ground
Step-by-step explanation:
t√h/4
h=125 feet
t=√125/4=√25×√5/4
t=5√5/4=11.18/4
t=2.79 secs
it takes the object 2.79 seconds to
hit theground
