Find the coordinates of the midpoint of the segment whose endpoints are H(5, 13) and K(7, 5). (12, 18) (9, 7) (2, 8) (6, 9)

____ [38]

Answer: D. (6, 9)

<u>Step-by-step explanation:</u>

Midpoint is the "average" of the x's and y's:

Given: (5, 13) and (7, 5)

Midpoint: $(\dfrac{5+7}{2},\dfrac{13+5}{2})$

= $(\dfrac{12}{2},\dfrac{18}{2})$

= (6, 9)

Explain how to find the surface area of a can of fruit with a height of 80 mm and a diameter of 60 mm. Give the area in your exp

8_murik_8 [283]

Answer:

$S=6600\pi \text{ mm}^2$

$S\approx 20724 \text{ mm}^2$

Step-by-step explanation:

A can of fruit is geometrically a cylinder.

We are talking about the <u>surface area of a cylinder</u>:

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

$\pi \approx 3.14$

$r: \text{radius}$

$h: \text{height}$

Factoring, we have:

$S=2\pi r (h+r)$

Calculating the surface area of the can of fruit:

$S=2\pi (30) (80+30)$

$S=2\pi (30) (110)$

$S=6600\pi$

$S\approx 20724 \text{ mm}^2$

Rotate 90 clockwise around the origin (-6,-2) (-3,1) (-1,1) (2,-4) please help me!

N76 [4]

The rule for a 90 clockwise rotation is basically an 180 degree rotation counterclockwise so (x,y) to (y,-x) so
(-6,-2) to (-2,6)
(-3,1) to (1,3)
(-1,1) to (1,1)
(2,-4) to (-4,-2)
