Which of the following equations is of a parabola with a vertex at (1, 2)? O y = (x - 1) 2 - 2
Oy= (x - 1)2 + 2
O y = (x + 1)2 - 2
O y = (x + 1)2 + 2

the second option: (x-1)squared +2

Explanation:

The x value of the vertex can be found in the parenthesis after the x. However, you have to do the opposite value of it. So, since the paranthesis has (x-1) then that means that the vertex's x-value has to be 1.

For the y-value of the vertex, that can be found after the paranthesis. This value will not be used as the opposite like with the x-value. So, we know that in (x-1)^2 +2 the "+2" indicates the y-value to be 2.

22733.28$(This is a rounded approximate answer)

Step-by-step explanation:

The equation for exponential growth is A = P(1 + r)^n where A is the total money(interest), P is the principal, r is the rate(compound interest rate) and n is the amount of time. If you look closely and read carefully, you will find out that the principle is $15000. The rate is 0.0325(converted into decimal) and the time is 13 years. If you plug in all of this, you should get A = 15000(1.0325)^13, and A will equal approximately 22733.28$.
