Mathematics

7 0

Answer:

32 yd^2

Step-by-step explanation:

Ignore rounded approximations (i.e. 2.66, 1.33). For all calculations, use fractions and EXACT values.

This prism has 6 surfaces:

  1. Front: 3 x 2.66 = 8
  2. Back: 3 x 2.66 = 8
  3. Top: 3 x 1.33 = 4
  4. Bottom: 3 x 1.33 = 4
  5. Side: 1.33 x 2.66 = 4
  6. Side: 1.33 x 2.66 = 4

Total SA: 8(2) + 4(4) = <u>32 yd^2</u>

  • Interest rate r = 1.5% or r = 0.015
  • Time t = 4 years
  • Number of compounds per year n = 1

<u>Find the future amount:</u>

1. How many ways are there to make an octagon with 19 different sticks when order DOESN’T matter?
mart [117]

Answer:

1. 19C8 = 75582

2. 19P8= 3047466240

Step-by-step explanation:

First, find the number of ways to get 8 sticks from 19. At first, you have 19 choices, then 18, then 17, all the way to 12. Giving you 19*18*17*...*13*12, or 19!/11!.

Combination:

When order doesn't matter, you have to divide 19!/11! by the number of ways to order 8 sides, or 19!/11!/8!=19C8=75582

Permutation:

When order doesn't matter, you don't have to divide 19!/11! by the number of ways to order 8 sides, since you count each of these, and 19!/11!=19P8=3047466240.
