Answer:
385.875 cm^3
Step-by-step explanation:
3.5/2 = 1.75
3.5^2 - 1.75^2 = 9.1875
3.5 * 9.1875/2 = 16.078
16.078 * 6 * 4 = 385.875
Step-by-step explanation:
4x + 8y = 40
4x + (8×0.8) = 40
4x + 6.4 = 40
4x = 33.6
4x÷4 = 33.6 ÷ 4
x = 8.4
Find the center, which is the midpoint of the two endpoints given.
(x1 +x2)/2 , (y1 +y2)/2
(4-2)/2 , (-3+5)/2
2/2 , 2/2
Midpoint = (1,1)
Find the radius, which is the distance from the center to an end point.
√(x2-x1)^2 +(y2-y1)^2
√(4-1)^2 + (-3-1)^2
√(3^2 + -4^2)
√9+16
√25
r = 5
The equation for a circle is written as (x-h)^2 + (y-k)^2 = r^2
h and k are the center points.
Replace the letters with their values to get:
(x-1)^2 + (y-1)^2 =25
Since lines with the same slope are parallel all u have to change about the original equation is the y intercept(b), so u just plug in the point into their variable and solve for b.
Answer: y=2x+2
