Answer:
The midpoint is (-2,7)
Step-by-step explanation:
To find the x coordinate of the midpoint, take the x coordinates of the endpoints, add them and divide by 2
(-9+5)/2 = -4/2 =-2
To find the y coordinate of the midpoint, take the y coordinates of the endpoints, add them and divide by 2
(3+11)/2 = 14/2 = 7
The midpoint is (-2,7)
The remaining factor of x^2y - 2xy - 24y is (x - 6)(x + 4)
<h3>How to determine the remaining factor?</h3>
The expression is given as:
x^2y - 2xy - 24y
Factor out y from the expression
y(x^2 - 2x - 24)
Expand the equation
y(x^2 + 4x - 6x - 24)
Factorize
y(x - 6)(x + 4)
Hence, the remaining factor of x^2y - 2xy - 24y is (x - 6)(x + 4)

Answer:
160 millimeters
Step-by-step explanation:
Just do 400*0.4
Answer:
x=4
Step-by-step explanation:
what i did is try to make some whole number and the minimum i got was 4.
1/4 = 0.25 so then do 12+4=16. then do 16*0.25=4. now do 4-6=(-2) then 1/2=0.5. now do 0.5* -2= -1. now do 4-1=3. now when there's no answer x can equal anything
I think I know what it forms - a cone!!
I'm guessing that the angles at the end are 10 degrees so that would make angle CAB equal 5 degrees.
Line AB would be the radius of the "upper cone".
Line BC is 12/2 or 6
tangent (A) = BC / AB
tangent (5) = 6 / AB
AB = 6 / tan(5)
AB = 6 / 0.087489
AB =

68.58 which is the radius of the "upper cone".</span></span></span>
Cone Volume = (PI * radius^2 * height) / 3
Cone Volume = (PI * 68.58 * 68.58 * 6) / 3
Cone Volume =

29,551
That is just the "upper cone volume. So, we multiply </span></span></span><span><span>

29,551 * 2
and get 59,102 which is the volume of the entire solid.
