Answer:
The equation of the axis of symmetry for this parabola is x = 0.
Step-by-step explanation:
For parabola's, it's axis of symmetry always goes through the vertex of the parabola. In other words, the axis of symmetry is vertical line that goes through the x-coordinate of the vertex.
Now, the vertex is given as (0,3) which is at x = 0, y = 3.
Thus, the vertical line that goes through the x-coordinate of the vertex will be x = 0
Thus, the equation of the axis of symmetry for this parabola is x = 0.
OK so 2/3 is0.66666666666666666666666666 and that needs to be multiplied by 100 to vet percent so 2/3 is 66.6%
ANSWER
Find out the how many years can she keep the car.
To proof
As given
Daniela bought a car for $24,000
Each year the value of the car decreases by $1750.
let us assume that the number of years be x.
when daniela sells her car she wants to get at least 10,000 for it.
Than the inequality becomes in the form
24000 - 1750 x ≤ 10000
solve
1750x ≤ 14000
![x \leq \frac{14000}{1750}](https://tex.z-dn.net/?f=x%20%5Cleq%20%5Cfrac%7B14000%7D%7B1750%7D)
x ≤ 8 years
she keeps the cars 8 years .
Hence proved
First, find the total inflation over the past 37 years: 37 years * 3.7%/year = 136.9 %. Then just multiply the original cost by the inflation and add the original cost so: ($20,000 * 1.369) + $20,000 = $47,380.
Answer:
32w^3 + 16x^2 - 8
Step-by-step explanation:
Perimeter = 2L + 2W
L = 9W^3 + 8W^2, W = 7w^3-4
2(9w^3 + 8w^2) + 2(7w^3 - 4)
= 18w^3 + 16w^2 + 14w^3 - 8
Combine like terms
32w^3 + 16w^2 - 8
