You haven't shared all of the question, so I'll guess that you want to find "how fast is the area of the sphere increasing?"
Area of a sphere = 4*pi*r^2
Rate of change of area of a sphere with respect to radius r:
dA/dr = 8*pi*r*(dr/dt)
Here, that would come out to
dA/dr = 8*pi*r*(2 inches / sec)
If you meant, "how fast is the volume of the sphere increasing?" you'd need to use a different equation:
V = (4/3)*pi)*r^3
and go through a similar process.
G(x) = 2^x is an exponential function and it increases at a faster rate.
Answer:
1/7
Step-by-step explanation:
You have a 8 sided die and yo roll it you also have 7 other sides so its 1/7
Answer:
width = 6 and length = 8
Step-by-step explanation:
perimeter = 2*(length + width). (1)
and we have that length = 2 + width
in (1)
28 = 2 *(width + 2 + width)
14= 2*width +2
width =6
and so length will be 8
The variable “x” can be defined as the price of regular gas.
The equation is x = x - (.02)7
x = x - (.02)7
(.02)7 = .14
x = x - .14
X - X = nothing so it just leaves you with -.14
The answer is that the gas price changed by a total of - 14 cents or -0.14
