Answer:

Exponential function

Step-by-step explanation:

It is better if the situation on ground is represented by an exponential equation.

This is because, since we have the number of teams reducing by exactly half at every playoff round, this means that we have a base of 2 which can be raised to a negative power since we are talking about a decrease.

We can then place the number of rounds as an adjoining power to what the two is raised and this easily will get us the number of teams which is eventually decreased at every point of the playoffs

|6x|+3=21 solve for X (absolute value)

Fudgin [204]

Answer:

$x=3\text{ or } x=-3$

Step-by-step explanation:

So we have the equation:

$|6x|+3=21$

First, subtract 3 from both sides:

$|6x|=18$

Definition of absolute value:

$6x=18\text{ or } 6x=-18$

Divide both sides by 6 for both equations:

$x=3\text{ or } x=-3$

And we're done!

A cone has a height of 2.5 in. and a radius of 5 in. What is the volume of the cone? (Use 3.14 for Pi. Round the answer to two d

Stells [14]

Answer:

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

And replacing we got:

$V = \frac{1}{3} (3.14) (5in)^2 (2.5in) = 65.42 in^3$

And the best option would be:

65.42 Inches cubed

Step-by-step explanation:

For this case we have the following info given:

$h =2.5 in$ represent the height of the cone

$r = 5 in$ represent the radius

And the volume of the cone is given by;

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

And replacing we got:

$V = \frac{1}{3} (3.14) (5in)^2 (2.5in) = 65.42 in^3$

And the best option would be:

65.42 Inches cubed
