So the formula for a volume of a sphere is 4/3 times pi times the radius cubed.
step one: 4/3 times 3.14 = 4.18666666667
Step two: then you cube 8.5 and get 592.45
the final answer is 2,480.3906
Answer:
y=-2x+15
Step-by-step explanation:
So first we can write it in point slope form.
That is y-y1=m(x-x1)
y1 is the y coordinate
m is the lope
x1 is the x coordinate
This means that the equation is:
y-7=-2(x-4)
We can then convert it to slope intercept form which is
y=mx+b
so
y-7=-2x+8
y=-2x+15
They are simple linear equations with one unknown, lets tackle them, one step at the time solving for the unknown:
4x - 2(x - 5) = x + 13
4x - 2x + 10 = x + 13
2x + 10 = x + 13
2x - x = 13 - 10
x = 3
that is the solution.
3(6 - x) - 4 = 5x + 2(7x + 3)
18 - 3x - 4 = 5x + 14x + 6
14 - 3x = 19x + 6
14 - 6 = 19x + 3x
8 = 22x
x = 8/22 = 4/11
It is rounded to the nearest 100,000th
5y-15x=-20
5y=15x-20
y=3x-20/3
Slope = 3
Slope Intercept Form
y-y1=m(x-x1)
Therefore y-(-6)=3(x-3)
y+6=3x-9
y=3x-15
