I NEED HELP!!! has endpoints X(7, 10) and Y(5, –8). Find the coordinates of the midpoint of .

Firlakuza [10]

The formula of a midpoint between X and Y:

$M_{XY}\left(\dfrac{x_X+x_Y}{2},\ \dfrac{y_X+y_Y}{2}\right)$

We have the points X(7, 10) and Y(5, -8). Substitute:

$\dfrac{7+5}{2}=\dfrac{12}{2}=6\\\\\dfrac{10+(-8)}{2}=\dfrac{2}{2}=1$

Answer:

2x -7

2x 4x² -14x

-1 -2x +7

Step-by-step explanation:

4x²-16x+7 factors as

(2x-7)(2x-1)

So the grid would be:

2x -7

2x 4x² -14x

-1 -2x +7

The part of a cylindrical soup can that is covered by the label is 8.5 cm tall and has a diameter of 6.5 cm. What is the area of

julia-pushkina [17]

Answer:

$180.4~cm^2$

Step-by-step explanation:

<u>Surface Area</u>

The surface area of a cylinder of height h and radius r is given by:

$A=2\pi rh$

It only covers the lateral side of the cylinder. If both the top and the bottom sides are to be included, then:

$A=2\pi rh+2\pi r^2$

The label will cover only the lateral side of the soup can that has a height of h=8.5 cm and a diameter of 6.5 cm. We need to calculate the radius which is half of the diameter r=6.5 cm / 2 = 3.25 cm.

Now we calculate the side area of the can:

$A=2\pi (3.25)(8.5)$

$A=173.6~cm^2$

We need to add the 0.8 cm overlap to the total area already calculated. This overlap has 0.8 cm of width and 8.5 cm of height, so this overlap area is:

$A_o= 0.8*8.5=6.8~cm^2$

The total area of the label is:

$A=173.6~cm^2+6.8~cm^2=180.4~cm^2$

The area of the label is $\mathbf{180.4~cm^2}$
