(04.04 MC) Which is the equation of the parabola?
1 answer:
Answer:
Option (2)
Step-by-step explanation:
Let the equation of the parabola represented by the curve in the graph is,
y = a(x - h)² + k
Where (h, k) is the vertex of the parabola and 'a' is the coefficients of highest degree term of the parabola.
From the graph,
Vertex of the parabola is (-3, 0) and a point (-13, -5) exactly lies on the curve.
vertex form of the parabola will be,
y = a(x + 3)² + 0
y = a(x + 3)²
Since (-13, -5) lies on this graph,
-5 = a(-13 + 3)²
-5 = 100a
a =
a =
So the equation of the parabola will be,
Option (2) will be the answer.

Answer:
Avery needs to pay $14.84
Step-by-step explanation:
When there's a tax we need to sum the original value of the product with the tax's value. To find the amount of money Avery needs to pay in taxes we can apply a rule of three as shown below:
Where "x" is the tax value, and $14 represents 100%, since it's the value used to calculate the tax. We have:
The value to be paid is the product value plus the tax, therefore:
Avery needs to pay $14.84
The final amount in the account after 25 years is $24670.42.
<h3>How do you calculate the final Amount after 25 Years?</h3>Given that 3400 dollars are placed in an account with an annual interest rate of 8.25% for 25 years.
The final amount in the account is calculated by the formula given below.
Where A is the final amount, P is the initial principal balance, R is the interest rate, T is the time period.
The final amount is given below.
Hence we can conclude that the final amount in the account after 25 years is $24670.42.
