Mathematics
1 answer:

Answer:

Hi, your answer is y=-\frac{1}{2} x-3

Step-by-step explanation:

We will use the slope-intercept formula which is

\frac{y2-y1}{x2-x1}

We will use two points in this case I'll use

(-2,-2) and (-8,1)

\frac{1-(-2)}{-8-(-2)}=-\frac{3}{6} which can be simplified as -\frac{1}{2}

Your Y will be -3

which your final answer will be y=-1/2x-3

Hope this helps :)

Charlie is trying to cover the shape shown with paper. He will NOT be covering the top and the bottom. How much paper will he ne
DENIUS [597]

You need to determine how much paper you need to cover the lateral side of the cylinder shown in the picture. For this, you have to calculate the surface area of the cylinder, which you can do using the following formula:

A=2\pi rh

Where

A is the area

π is the number pi, for the calculations we usually use up to the first two decimal values of this number, 3.14

r is the radius

h is the height of the cylinder

The given cylinder has a height of h=15m and a diameter of d=6m

To calculate the lateral area you need to use the radius. The diameter is twice the radius, so to determine the radius of the cylinder you have to divide the diameter by 2

\begin{gathered} r=\frac{d}{2} \\ r=\frac{6}{2} \\ r=3 \end{gathered}

Now you can calculate the lateral area as follows:

\begin{gathered} A=2\pi rh \\ A=2\cdot3.14\cdot3\cdot15 \\ A=282.6m^2 \end{gathered}

Charlie will need 282.6 m² to cover the lateral side of the cylinder.

(-4,5) and (4,0) find the distance between each pair of points
aleksklad [387]

Answer:

9.4339 units

Step-by-step explanation:

Here we are given with two coordinates and asked to determine the distance between them.

Here we are going to use the distance formula, which is given as under

D=\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}

Where

(x_1,y_1) = (-4,5)

(x_2,y_2) = (4,0)

Replacing these values in the distance formula

D =\sqrt{(-4-4))^2+(5-0)^2}

D =\sqrt{(-8)^2+(5)^2}

D =\sqrt{64+25}

D =\sqrt{89}

D= 9.4339

Hence the distance is 9.4339 units
