Answer: 336

Step-by-step explanation:

Given : The total number of runners = 8

The number of positions = 3

Since for awarding prize, the order of winners matters.

So by permutations ,the number of possible ways to award 3 prizes will be

^8P_3=\dfrac{8!}{(8-3)!}=8\times7\times6=336

Therefore , the total number of ways by which runners finish in first, second, and third place is 336.

a cone with a radius 3 units is shown below. it’s volume is 57 cubic units. find the height of the cone
ipn [44]

<u>Given</u>:

Given that the radius of the cone is 3 units.

The volume of the cone is 57 cubic units.

We need to determine the height of the cone.

<u>Height of the cone:</u>

The height of the cone can be determined using the formula,

V=\frac{1}{3} \pi r^2 h

Substituting the values, r = 3 and V = 57, we get;

57=\frac{1}{3} (3.14) (3)^2 h

Simplifying the terms, we get;

57=\frac{1}{3} (3.14) (9) h

Multiplying both sides of the equation by 3, we get;

171= (3.14) (9) h

171=28.26 h

Dividing both sides of the equation by 28.26, we get;

6.05=h

Thus, the height of the cone is 6.05 units.

Effectus [21]

Answer:

1. -8x² - 16x - 6      a = -8, b = -16, c = -6

1. 4x² - 1                  a = 4, b = 0, c = -1

Step-by-step explanation:

use the 'foil' method:

(4x + 2)(-2x - 3)

F: -8x²     O: -12x       I: -4x       L: -6

-8x² - 16x - 6

(2x + 1)(2x - 1)

F: 4x²     O: -2x       I: 2x       L: -1

4x² - 1
