Answer:

  y = 1 · 5^x

Step-by-step explanation:

Use the given values in the given formula and solve for 'a' and 'b'.

  y = a·b^x

  5 = a·b^1 . . . . . . for (x, y) = (1, 5)

  125 = a·b^3 . . . . for (x, y) = (3, 125)

Divide the second equation by the first:

  125/5 = (a·b^3)/(a·b^1)

  25 = b^2 . . .  simplify

  5 = b . . . . . . . take the square root

Substituting into the first equation, we can find 'a':

  5 = a·5

  1 = a . . . . . . . divide by 5

Written in the given form, the equation is ...

  y = 1 · 5^x

Pending Review Question 7
vitfil [10]

Answer:

$ 2,200 for 8%, $ 1,300 for 12%

Step-by-step explanation:

I=PRT

Let Bank 1 be <em>x</em>

332= x (8%) + (3,500-x) 12%

332= x (0.08) + (3,500-x) 0.12   change the percent to decimal

332= 0.08x + 420 - 0.12x

0.04x= 420-332

x= \frac{88}{0.04}

x= 2,200 (Bank 1)

Bank 2= 3,500-Bank 1

Bank 2= 3,500- 2,200

Bank 2= 1,300
