Answer:

Step-by-step explanation:

Volume of a cone = 1/3 πr^2h

r = diameter/2

V = 1/3 × 22/7 × 22/2 × 22/2 × 22

V = 1/3 × 22/7 × 11 × 11 × 22

V = 58564/21

V = 2788.76 yd

Digiron [165]

This system has one solution y=8x+9, y=x^2+4x+13. What is the y coordinate

y=8x+9<= y=8x+9 <== 8x+9: m=8

y=x^2+4x+13<= y <==x^2+4x+13: minimum (-2,9)

y=8x+9 and y.No solution

An NFL coach sometimes uses a defense that utilizes 3 defensive linemen, 4 linebackers, and 4 defensive backs. His roster (the p

Alexandra [31]

Answer:

68,600

Step-by-step explanation:

The order of the players is not important. For example, a defensive line of Shaq Lawson, Ed Oliver and Jerry Hughes is the same as a defensive line of Ed Oliver, Shaq Lawson and Jerry Hughes. So we use the combinations formula to solve this question.

Combinations formula:

$C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

Defensive Lineman:

3 from a set of 8. So

$C_{8,3} = \frac{8!}{3!5!} = 56$

56 combinations of defensive lineman

Linebackers:

4 from a set of 7. So

$C_{7,4} = \frac{7!}{4!3!} = 35$

35 combinations of linebackers

Defensive backs:

4 from a set of 7. So

$C_{7,4} = \frac{7!}{4!3!} = 35$

35 combinations of defensive backs

How many different ways can the coach pick the 11 players to implement this particular defense?

56*35*35 = 68,600

68,600 different ways can the coach pick the 11 players to implement this particular defense
