GRADE 11 MATH
Romashka-Z-Leto [24]

The amount that was invested 17 years ago is $2064.25.

The interest earned is  $7935.75.

<h3>What is the amount invested 17 years ago?</h3>

The formula that would used to determine the amount that was invested 17 years ago is:

P = FV / (1 + r)^nm

Where:

  • FV = Future value = 10,000
  • P = Present value
  • R = interest rate = 9.5 / 2 = 4.75%
  • m = number of compounding = 2
  • N = number of years = 17

10,000 / (1.0475)^(17 x 2) = $2064.25

Interest earned = 10,000 - 2064.25 = $7935.75

Can ratios have decimals in them or do all the numbers have to be integers? E.g. is 7.8:1.3:6.5 a valid ratio?
nadezda [96]
What you have is a valid ratio in theory, but it might be easier to understand if it were simplified to integers:

78:13:65

It also depends on what your teacher is asking of you.

I need help with this my brain cant comprehend
Rom4ik [11]
The function is symmetric in the line that goes trough the top. The top is on t=2.5 seconds. If you want to know on which time the height is equal to 15 feet, you draw a line on that height in the graph and see where it crosses. That is at t=1.25 and t=3.75
