Square root 7 equals 2.6 to the nearest tenths
The answer is 5/6.
The yellow (including the overlap) covers 5 columns of the 6 columns.
That makes 5/6.
Answer:
When we have a function g(x) such that:
g(x) = y.
Then the inverse, h(x), must be such that:
h(y) = x.
This means that:
g( h(x) ) = x
h( g(x) ) = x.
In this case, g(x) = 41*x^3 + a.
Then:
g( h(x)) = x = 41*h(x)^3 + a.
Now we can solve it for h(x).
x - a = 41*h(x)^3
(x - a)/41 = h(x)^3
∛( (x -a)/41 ) = h(x)
h(x) is the inverse function of g(x).

Answer:
<em>Josh would need to purchase 20 gallons of gas for the cost to be the same at each car wash</em>
Step-by-step explanation:
We need to model both car wash's costs. The Quik-Clean Car Wash charges $15 for a car wash plus $2.50 per gallon for unleaded gasoline. If x is the number of gallons of unleaded gasoline. the total charges of this store are:
C1=15+2.5*x
The Mighty Clean Car Wash charges $10 for a carwash plus $2.75 per gallon for unleaded gasoline. Following the same procedure, their costs are:
C2=10+2.75*x
Josh wants to know how many gallons of gas will make both businesses charge the same. Equating both equations:
15+2.5*x=10+2.75*x
Simplifying:
-0.25x=-5
Solving:
x=-5/(-0.25)=20
Josh would need to purchase 20 gallons of gas for the cost to be the same at each car wash
