Answer: 5^7 x 3^7
You could also write 15^7
Answer:
1
Step-by-step explanation:
1 1/3 = 4/3
4/3 - 1/3
drop the bottom 3 since it is a common denominator
4 - 1 = 3
bring the 3 back
3/3 = 1
If the eqn of the parabola is f(x) = (x-4)(x+2), we need to mult. this out to find the coordinates of the vertex.
Then f(x) = x^2 + 2x - 4x - 8, and f(x) = x^2 - 2x - 8.
One way in which you can find the vertex is to calculate x = -b / (2a). Here, that comes to
-(-2)
x = ---------- = 1. f(1) = 1^2 - 2(1) - 8 = - 9. Vertex is at (1, -9).
2(1)
Find another point on the curve: Let x=0, for which y=-8. Then (0, -8) is on the curve. Plot the vertex and this point and draw a smooth parabola thru both.
<em>The question has missing details. However, general questions that could be asked is as follows:</em>
<em>(1) The number of miles traveled after using (say) 5 gallons</em>
<em>(2) The number of gallons used after traveling for (say) 36 miles</em>

Step-by-step explanation:
Given

A linear equation is represented as:

Where
and

c, in this question represents the initial capacity of the tank.
So, the initial capacity is 120 liters
Solving (a): r = 5




<em>60 miles traveled</em>
Solving (b): s = 36


Collect like terms


Solve for r

<em>42 gallons used</em>
