Find how far the car can travel on one gallon of gas, by dividing total miles by number of gallons:
105 miles / 7 gallons = 15 miles per gallon.
Now multiply that by the number of gallons to find total miles:
15 miles per gallon x 9 gallons = 135 total miles.
Part A
After dividing the first two terms by the coefficient of n², the coefficient of the linear term is -6, so we can complete the square by adding (and subtracting) the square of half that: (-6/2)² = 9.
... g(n) = n² -6n + 9 + 16 - 9
... g(n) = (n -3)² +7 . . . . . . . rewrite to vertex form
Part B
The generic vertex form is
... y = a(x -h)² +k . . . . . . for vertex (h, k) and vertical expansion factor "a"
Comparing this to g(n), we see a=1, h=3, k=7. When a > 0, the parabola opens upward, and the vertex is a minimum. Here, we have a > 0, so we can conclude ...
... the vertex (3, 7) is a minimum
Part C
The axis of symmetry is the vertical line through the vertex.
... x = 3
Answer:
B 8 n^18
Step-by-step explanation:
The area of a square is given by
A = s^2 where s is the side length of a square
64 n^36 = s^2
Take the square root of each side
sqrt(64 n^36 )= sqrt(s^2)
Sqrt(ab) = sqrt(a) sqrt(b)
sqrt(64) sqrt(n^36) = s
8 n^18 =s
Its 8, 14x-34=78 add 34 to 78 then divide by 14
