Answer:
Rate of change of the diameter is equal to 0.053cm/min
Step-by-step explanation:
A snowball is of the shape of a sphere
Surface area of Sphere (S)=
Rate of change of surface area
dS/dt = -4
the negative sign indicates the surface area is decreasing.
Radius = d/2 where d represents diameter
using this is the surface area equation
S =
=
dS/dt = 2*pi*d*d(d)/dt
4 = 2*pi*d*(d)/dt
d(d)/dt = 2/12*pi= cm/min
so the rate of change of the diameter is equal to 0.053cm/min
Answer:
Option C is correct.
The y-intercept of the graphed function is;
Explanation:
To find the y-intercept of the graphed function:
The point where the graph crosses the y-axis is call y-intercept.
You can also find the y-intercept by looking at the given graph and seeing which point crosses the y-axis also this point will always have an x-coordinate of 0.
End behavior of a polynomial function is the behavior of the graph of function as x approaches or
Also, the degree and the leading coefficient of a polynomial function determine the end behavior of the graphed function.
therefore, the y-intercept of the graphed function is; (0, -9)
