Answer:
see explanation
Step-by-step explanation:
1
(x + 5)² = 4 ( take the square root of both sides )
x + 5 = ± = ± 2 ( subtract 5 from both sides )
x = - 5 ± 2, thus
x = - 5 - 2 = - 7
x = - 5 + 2 = - 3
--------------------------------------------
2
(x + 6)² = 7 ( take the square root of both sides )
x + 6 = ± ( subtract 6 from both sides )
x = - 6 ± , thus
x = - 6 -
x = - 6 +
------------------------------------------------
3
(x - 2)² = 18 ( take the square root of both sides )
x - 2 = ± = ± = ± 3 ( add 2 to both sides )
x = 2 ± 3, thus
x = 2 - 3
x = 2 + 3

Step-by-step explanation:
Incomplete question as the function is not given. So, I will give a general solution
Required
Determine the average rate of change from t = 2 to 4
Average rate of change is :
In this case: a = 2 and b = 4
So, we have:
Assume that the exponential function is:
f(4) and f(2) will be:
So:
Take LCM
<em>So, the average rate of change is a decrease of 4/81</em>
Answer:
<h2>m
6 = 68°</h2>
Step-by-step explanation:
From the question all the angles are on a a straight line which means the sum of their angles is 180 and one of the angles is 90°
So to find m 6 , add
m 5 and 90 and subtract the result from 180°
That's
m5 + m6 + 90 = 180
m6 = 180 - 90 - m5
m6 = 180 - 90 - 22
We have the final answer as
<h3>m
6 = 68°</h3>
Hope this helps you
Answer: (-2, 2) and (4, 8)
There are two solutions because the two functions cross each other twice.
