We will see that the cost of filling the tank is $38.88, and at the final of the trip she will have 4 gallons on the tank.
<h3>
How much costs to fill the tank?</h3>
a) The car holds 18 gallons, and it has 1/5 of the tank remaining.
Then in the tank there are:
(1/5)*18 = 3.6 gallons.
Then we need 18 gal - 3.6 gal = 14.4 gal
And each gallon costs $2.70, then to fill the tank, Miss Kito needs:
(14.4)*$2.70 = $38.88
b) Now we know that the car travels 26 miles per gallon, and she needs to travel a total distance of 364 miles.
Then she needs:
To travel that distance, and the car holds 18 gallons, so at the end of the trip, she will have 4 gallons of gasoline in her car.

Answer:
A(t) = 676π(t+1)
Correct question:
A rain drop hitting a lake makes a circular ripple. Suppose the radius, in inches, grows as a function of time in minutes according to r(t)=26√(t+1), and answer the following questions. Find a function, A(t), for the area of the ripple as a function of time.
Step-by-step explanation:
The area of a circle is expressed as;
A = πr^2
Where, A = Area
r = radius
From the case above.
The radius of the ripple is a function of time
r = r(t) = 26√(t+1)
So,
A(t) = π[r(t)]^2
Substituting r(t),
A(t) = π(26√(t+1))^2
A(t) = π(676(t+1))
A(t) = 676π(t+1)
