100 lbs = 1 lb of melon 99 lb water
Let "x" be weight of water:
percentage = weight of water / (1 lb melon + water)
.98 = x / (1 lb melon + x)
.98 = x / 1 +x
.98 + .98x = x
.98 = .02x
x = 49
49 lbs of water
1 lb melon + 49 lbs water = 50 lbs total
49 / 50 = 98%
Therefore, 50 POUNDS of water evaporated
9a. The answer is 1.07% because the function shows an exponential growth in the exponential function.
9b. The first population was about 2622 because it shows that the first year is the domain to find the range of the function when x is equal to 1.
X=10
Because X=10 and x=10
Answer: 
==================================================
Explanation:
We simply add the expressions we are given, though we cannot combine the terms (as they aren't like terms). There's not much to show in terms of steps, though I guess you could have the following:

Adding 4 onto 2^x means we shift the 2^x curve up four units.
Answer:
No, since it is na exponent
Step-by-step explanation:
If it was to the 2nd power, then the problem would simplify to 36x^2(9x^2)(16)
