Answer:
Step-by-step explanation:
Midpoint formula: ( (x1+x2)/2, (y1+y2)/2)
where (x1, y1) and (x2, y2) are our points
Let (x1, y1) = (4, 5)
and (x2, y2) = (9, 17)
x1 = 4
x2 = 9
y1 = 5
y2 = 17
Then ( (4+9)/2, (5+17)/2 ) = (13/2, 22/2) = (13/2, 11)
Area of polygon
=n(base * apothem)/2
=5*9*8/2
=180 mm^2
Volume of prism
=cross-sectional area * height
=180*28
=5050 mm^3
<h3>Answer: (-1, -3)</h3>
===================================
How I got that answer:
- Step 1) Plot the point P = (-1,5)
- Step 2) Draw a horizontal line through 1 on the y axis to create the line y = 1.
- Step 3) Starting at point P, move down 4 spaces until you reach (-1,1) which is on the horizontal line. I'll call this point A.
- Step 4) Move another 4 spaces vertically downward until you arrive at (-1, -3). This is the location of P' and it is the final answer.
The distance from P' to A is the same as the distance from P to A. In other words, P'A = PA.
A diagram is provided below.
The hypotenuse is always the c value (the one that doesnt connect to the right angle). For a and b, it doesnt really matter.
Okay organize first and you get
60, 60, 66, 77
even witch means you have to add the middle numbers then divide
60+66=126 divide by two = 63
your answer is B. 63 acres
hope this helped!
