Answer:
30 days (do correct me if I'm wrong haha)
Step-by-step explanation:
5 gallons = 2 days
75 gallons = 30 days
75÷5=15 15×2=30
We'll use the notation
for the principal value and
for all the values:

Part I


Part II. In our range we can write


Part III.

Part IV.


Answer:

Step-by-step explanation:
The standard equation for circle is

where point (a,b) is coordinate of center of circle and r is the radius.
______________________________________________________
Given
center of circle =((-2,3)
let r be the radius of circle
Plugging in this value of center in standard equation for circle given above we have

Given that point (1,2 ) passes through circle. Hence this point will satisfy the above equation of circle.
Plugging in the point (1,2 ) in equation 1 we have

now we have value of r^2 = 10, substituting this in equation 1 we have
Thus complete equation of circle is 
Answer:
378
Step-by-step explanation:
9*6=54 then 54/2=27. fnally 27*14=378
The general form of an equation is

. Solving for (5+X)(5-X)=7 by multiplying the factors and subtratcting 7 on both sides gives the equation

, so
A = 1
B = 0
C = -18
