Answer: (-2,-1)
Step-by-step explanation:
A and B are the endpoints and we know that to find the midpoint, we need to find the average between the x and y values.
The x coordinate of A plus the x coordinate of B has to equal 0. We can represent that by the equation
now solve for x to find the x coordinate of B by first multiplying both sides by 2.
x + 2 = 0 Subtract 2 from both sides
-2 -2
x = -2
So the x coordinate is -2 now find the y coordinate using the same method.
Multiply both sides by 2
-5 +y = -6 Add -5 to both sides
+5 +5
y = -1
The y coordinate is -1
so the coordinates of B is (-2,-1)
Answer:
x = 0

Answer:
Do you know the cylinder volume formula?Answer is: V=Pi*r^2*h Let me explain what that means. So the Pi is a constant number equal to 3.14..... and continue and this doesn't effect the volume while radius and height are the ones who do that.The volume is more effected by the radius because if both of them are a same number the radius would be greater than the height.
If r= 2 and h=2 than V=Pi*2^2*2 V=3.14*4*2
Step-by-step explanation:
Let me solve the problem!
a) r=3 h=10 than V=Pi*3^2*10 V=Pi*9*10 V=90Pi
When we increase the raduis by 1
b)r=4 h=10
V=Pi*4^2*10 so V=Pi*16*10 so V=160Pi
c)r=3 h=11
V=Pi*3^2*11 so V=Pi*9*11 so V=99Pi
It meas that when the radius is increased by 1inc the volume is greater than when you increase the height by 1.
