Answer:
Step-by-step explanation:
<u>Given line:</u>
It has a slope of 2/3.
<u>Perpendicular lines have negative-reciprocal slopes, so the perpendicular slope is:</u>
<u>Find its equation provided it passes through the point (4, - 2):</u>
- y - (-2) = - 3/2(x - 4)
- y + 2 = - 3/2(x - 4)
Answer:
with what do u need help with?
You would take out a 4x out of both terms because this is a common factor
4x^3-36x
4x(x^2-9)
and then you would notice that (x^2-9) is a difference of squares, so that factors out too
4x(x-3)(x+3)
that is all you can factor! hope this helps
Answer:
10.8
Step-by-step explanation:
to so the mean you add up all of the numbers and divide by the amount you have. so add up all the numbers to get 54, the divide 54 by 5 because there are numbers.
The endpoints of a diameter of a circle are (4,-2) and (3,6). The area of the circle in terms of pi is 65pi
First, is to get the length of the diameter by getting the distance of the two points: (4, -2) and (3, 6)
dis = sqrt( (x2-x1)^2 + (y2-y1)^2)
dis = sqrt( (3-4)^2 + (6--2)^2 )
dis = sqrt( 1 + 64 )
dis = sqrt(65)
Next, is to find the area of the circle:
A = pi * r^2
A = pi * (sqrt(65))^2
A = 204.20 square units
