Mathematics
1 answer:
zysi [14]3 years ago
5 0

Answer:

a = 3, -3

Step-by-step explanation:

Multiply (a+3)/(a+3) to 2/(a-3) and multiply (a-3)/(a-3) to 2/(a+3) to get:

2(a+3)/(a-3) and 2(a-3)/(a+3) which equals (2a+6)/(a^2-9) and (2a-6)/(a^2-9)

add those two together to get (4a)/(a^2-9) which is equal to a/(a^2-9) on the other side. Cross multiply to get 4a^3 - 36a = a^3 - 9a, add/subtract like terms and you get a = 3 or -3

13 is the answer. You would first list the numbers from least to greatest. Then you would find which number is in the middle. But since it would be between 12 and 14, since there is no even middle, you would find the middle of 12 and 14. And 13 is between 12 and 14. Sooooooo....

13 is the answer.

A rock is released from rest and freely falls 70 m to the ground. What is its velocity just before impact? A. 1.2 m/s B. 7.0 m/s
Yuri [45]

Answer:

37.04 m/s

Step-by-step explanation:

we can use the equation x = x0 + v0t + 1/2at^2

a = -9.8 m/s^2, the acceleration due to gravity

x0 = 70 m, the starting point of x

v0 = 0 m/s

x = 0

this will allow us to solve for time

0 = 70 + 0 +-4.9t^2

t = 3.779

now we can use the equation v = v0 + at

v = 0 + 9.8(3.77)

v = 37.04 m/s
