Help me please I am completely lost
Irina-Kira [14]
Okay, your answer is 182. You really do not need to look at the crazy stuff on the paper about the crazy numbers. Look at the graph. It is counting up by 20's on the left side. But on the right side, the whole time it is counting up by 13's. Your answer is 182.

Find the coordinates of the midpoint M of the segment with the given endpoints. Then find the distance between the two points. R
Mrac [35]

Answer:

Midpoint (-2,4)

distance nearest tenth = 8.9

The approximate distance = 9

Step-by-step explanation:

Formulas

PQ midpoint = (x2 + x1)/2, (y2 + y1)/2

distance d = sqrt( (x2 - x1)^2 + (y2 - y1)^2 )

Givens

x2 = -4

x1 = 0

y2 = 1

y1 = 7

Solution

M(PQ) = (-4+0)/2, (1 + 7)/2

M(PQ) = -2, 4

The midpoint is -2,4

The distance = sqrt( (4 - 0)^2 + (1 + 7)^2 )

The distance = sqrt(16 + 64)

The distance = sqrt(80)

The distance = 4√5           exactly

The distance = 8.94    

The distance = 8.9            To the nearest tenth

Question 2

The distance is rounded to the nearest whole number which is 9.

Find the area of an equilateral triangle (regular 3-gon) with the given measurement. 6-inch radius A = sq. in.
katovenus [111]
\bf \textit{area of an equilateral triangle}\\\\&#10;A=\cfrac{s^2\sqrt{3}}{4}\qquad &#10;\begin{cases}&#10;s=length~of\\&#10;\qquad a~side\\&#10;-------\\&#10;s=6&#10;\end{cases}\implies A=\cfrac{6^2\sqrt{3}}{4}\implies A=\cfrac{36\sqrt{3}}{4}&#10;\\\\\\&#10;A=9\sqrt{3}
