Surface area = 4 pi r^2
where
pi : 3.14 a constant
r : raduis
surface area is the change of volume with respect to raduis
volume = 4/3 pi r^3
dvolume/dr = 4 pi r^2
you can prove the identity with double integration in spherical coordinates or volumes of revolutions and polar coordinates
First you'll use the slop formula to find the slope.
Slope =

Slope =

Slope =

Slope =

Now we write the equation.
y = mx + b
y = -3x + 9
In this equation -3 is the slope and 9 is the y-intercept.
Hope this helps :)
Answer:
700 x 0.0675 x t = 16,300
47.25t = 16,300
t = 16,300 / 47.25
t = 344.97 years
answer
344.97 years
Step-by-step explanation:
-3 because 4 times -3 = -12 -7=-19
2 y = - x - 12 y = x + 5
- x - 1 = x + 5- 2 x = 5 + 1- 2 x = 6x = - 6 : 2x = - 32 y = - 3 + 52 y = 2y = 1The solution is ( - 3 , 1 ).Answer: x = - 3.
