Answer:
58.74 cubic meters
Step-by-step explanation:
The function is actually 
Here x is the number of days and the corresponding value of "f(x)" would be the water REMAINING after x days.
Since, we want to figure out how much water (from 60 m^3) is remaining after 7 days, we simply have to plug in x = 7 into the function. Whatever number we get, is the AMOUNT OF WATER REMAINING AFTER 7 DAYS.
So,

Thus, the amount of water remaining in the pool after 7 days is 58.74 cubic meters
Answer:
260 ok
Step-by-step explanation:
Hi there!
The answer is

In this formula d represents the diameter.
We know that 2 times the radius equals the diameter, hence

Therefore we can replace the 2r in the original formula by d, and then we get the following:
<span>The first quartile (Q1) is defined as the middle number between the smallest number and the median of the data set.</span>
X^2-6x+y^2+2y-39=0 =(x-3)^2 -9 + (y+1)^2 -1-39=0 so (x-3)^2 + (y+1)^2 = 49 . The center is at (3,-1) and the radius is 7 units.
