Answer: 45 minutes
Step-by-step explanation:
the first pump takes care of 300 gallons so we need to worry about the remaining 900 gallons. the second pump removes 20 gallons per minute so all u have to do to find how many minutes it would take is divide 900 gallons by 20 gallons a minute which gives you 45
it will take 45 minutes to completely drain the pool
The inverse function is:
And g(2) = 212.
<h3>
How to get the inverse function?</h3>
We need to find g(x) such that:
g(h(x)) = x.
We know that:
![h(x) = \frac{\sqrt[3]{x + 4} }{3}](https://tex.z-dn.net/?f=h%28x%29%20%3D%20%5Cfrac%7B%5Csqrt%5B3%5D%7Bx%20%2B%204%7D%20%7D%7B3%7D)
Then our function must be a cubic, multiplied by 3^3 = 27, and then subtracts 4, it is:
As you can see, if you evaluate in h(x), the outcome is x.
Now we can evaluate this in x = 2, we get:
The correct option is C.

Answer:
Step-by-step explanation:
5/9m=15
9/5x5/9 cross that out and you have to do 15/1x9/5 which is 3/1x9/1 which is 27 muffins.
multiple 9/5 by 5/9 because of the recipricol which evens out that number because it becomes whole. then do the same thing to the 15 and you simplify both the fractions then multiply which creates 27, or just look at 5/9 and 15/x 15 divided by 5 is 3 and 3 times 9 is 27 tada!!
your x value is your slope so the slope is 6 and your y intercept is the y value so your intercept is 3
hope this helps
