Fynjy0 [20]

Answer:

6.69 cm

Step-by-step explanation:

Given data

Diameter= 12cm

Radius= 6cm

Volume= 757.36cm^3

The expression for the volume of a cylinder is

V= πr^2h

Substitute

757.36= 3.142*6^2*h

757.36=113.112h

h= 757.36/113.112

h= 6.69 cm

PLEASE HELP ME!!!

<h3>Answer:  15 years old</h3>

=============================================

Explanation:

m = Maggie's age (some positive whole number)

4m = four times her age

4m-7 = seven years younger than 4m = brother's age

Add up her age (m) and her brother's age (4m-7) to get a sum of 68.

m+(4m-7) = 68

5m-7 = 68

5m = 68+7

5m = 75

m = 75/5

m = 15

Maggie is currently 15 years old.

Her brother is currently 4m-7 = 4*15-7 = 60-7 = 53 years old.

Their current year ages add to: 15+53 = 68 which confirms the answer.

What is the graph of the function f(x) = the quantity of x plus 2, all over x minus 3
Andrej [43]

Answer:


Step-by-step explanation:

The given function is f(x)=\frac{x+2}{x-3} and we need to graph it.

In order to graph this function, we'll find below things:

Horizontal asymptote:

Since the degree of both numerator and denominator is same. Hence, the horizontal asymptote is the ratio of leading coefficient of numerator to the leading coefficient of  denominator.

Horizontal  asymptote is y = 1/1 = 1

Vertical asymptote:

Vertical asymptote occurs where the denominator is zero.

x-3=0\\x=3

x-intercepts:

For x-intercept, y = 0

\frac{x+2}{x-3}=0\\\\x+2=0\\x=-2

y-intercepts:

For y-intercept, x= 0

y=\frac{0+2}{0-3}=0\\\\y=-\frac{2}{3}

Using these, we can draw the graph of the rational expression.
