Answer:

r = A/(Pt) -1

Step-by-step explanation:

To solve for r, we undo the operations done to it. r is ...

  • added to 1
  • and the sum multiplied by Pt

We undo these operations in reverse order, so we first divide by Pt:

... A/(Pt) = 1 + r

Then, we subtract 1:

... A/(Pt) -1 = r

Draw a quadratic function below with zeros at -3 and 5 that is also concave up.
tia_tia [17]

Hello from MrBillDoesMath!

Answer:

x^2 - 2 x - 15

Discussion:

( x - (-3)) * ( x- 5) =

(x +3) (x-5) =

x^2 - 2 x - 15

It is a concave upward curve (looks like a "u") as the x^2 term causes the function to grow larger as x approaches +\- infinity.

Thank you,

MrB
