Step-by-step explanation:
Given:
Donald Duck's car travels in 1 gallon gas = 30 miles
Cost of 1 gallon = $ 2.19
Question asked:
Distance travel in 9.2 gallons = ?
Cost of 9.2 gallons of gas = ?
Solution:
By applying unitary method:
His car travels in 1 gallon = 30 miles
His car will travel in 9.2 gallons =
= 276 miles
Cost of 1 gallon = $ 2.19
Cost of 9.2 gallons =
= $ 20.148
Answer:
Step-by-step explanation:
we have
we know that
The equation of a vertical parabola into vertex form is equal to
where
(h,k) is the vertex of the parabola
and the axis of symmetry is equal to
In this problem we have the axis of symmetry
so
the x-coordinate of the vertex is equal to
therefore
For -----> one unit to the right of the vertex
Find the value of
For -----> one unit to the left of the vertex
Find the value of
Remember that
------> the x-coordinates are at the same distance from the axis of symmetry
so
------> solve for b
