Answer:
9670 feet
Step-by-step explanation:
The height given (8219.5 ft) is 85% OF ORIGINAL, hence original is much higher. But how do we figure this out?
<em>we translate word problem to equation.</em>
<em />
<em>8219.5 IS 85% of TOTAL</em>
<em />
Firstly, 85% = 85/100 = 0.85
Remember, is means =
of means multiplication
So we have:
<em>8219.5 = 0.85 * Total</em>
<em>Hence, total = [let total be 7]</em>
<em>8219.5 = 0.85 * t</em>
<em>t = 8219.5/0.85 = </em><em>9670 feet</em>
Start with the parentheses first
4.6 -4.4+7.8 then calculate from left to right
= 0.2+7.8 = 8
Answer:
, x>=0
Step-by-step explanation:

To find the inverse function , replace f(x) by y

Replace x with y and y with x

Solve the equation for y
take square root on both sides

Now subtract 6 from both sides

replace y with g(x)

C the property for this states that the order may change but the the answer will remain the same
