#2) A lifeguard is swimming to a drowning swimmer. The lifeguard's location is at
Ulleksa [173]

Answer:

<h3>9.43</h3>

Step-by-step explanation:

The formula for calculating the distance between two points is expressed as

D =√(x2-x1)²+(y2-y1)²

Given the coordinates (0,0) and (8,5)

D = √(5-0)²+(8-0)²

D = √5²+8²

D = √25 + 64

D = √89

<em>D = 9.43</em>

<em>Hence the distance between the life guard and the swimmer is 9.43</em>

This Stem-and-Leaf Plot shows the amount of rainfall received in centimeters in each month. What is the median of this data set?
WARRIOR [948]

Answer:

55.5 B

Step-by-step explanation:

We have the following points of data

48, 49, 50, 51, 54, 55, 56, 58, 60, 62, 63, 63

The median is the data point in the middle (when listed in order)

If we find the middle number we'll see that it's between 55 and 56. When this is the case you find the average of  the two numbers (add them and divide by 2)

(55+56)/2=55.5

Rearrange the formula V = 1 3 πr2h for h. A) h = 3V πr2 B) h = V 3πr2 C) h = 3πr2 V D) h = πr2 3V
stiks02 [169]

Answer:

Option a) h=\frac{3V}{\pi r^{2} }

Step-by-step explanation:

The given formula seems to represent the volume of right circular cone. The correct formula is:

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

We have to rearrange the formula for h. This means we have to move h on one side of the formula and all the other variables and constants on the other side of the equation. This can be done as shown below:

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