They both have to be above the x axis, which makes B incorrect. B will be below the x axis. If you have a graphing calculator or know where there is one of the net, you can try it.
A and D are both wrong. The 1/2 does not become 2. What will happen is that 2 will make the graph wider.
There's only 1 answer left and that is
C <<<<<===== answer.
C reflects right across the y axis.
Answer: ∆V for r = 10.1 to 10ft
∆V = 40πft^3 = 125.7ft^3
Approximate the change in the volume of a sphere When r changes from 10 ft to 10.1 ft, ΔV=_________
[v(r)=4/3Ï€r^3].
Step-by-step explanation:
Volume of a sphere is given by;
V = 4/3πr^3
Where r is the radius.
Change in Volume with respect to change in radius of a sphere is given by;
dV/dr = 4πr^2
V'(r) = 4πr^2
V'(10) = 400π
V'(10.1) - V'(10) ~= 0.1(400π) = 40π
Therefore change in Volume from r = 10 to 10.1 is
= 40πft^3
Of by direct substitution
∆V = 4/3π(R^3 - r^3)
Where R = 10.1ft and r = 10ft
∆V = 4/3π(10.1^3 - 10^3)
∆V = 40.4π ~= 40πft^3
And for R = 30ft to r = 10.1ft
∆V = 4/3π(30^3 - 10.1^3)
∆V = 34626.3πft^3

Answer:
4665 approx
Step-by-step explanation:
Given data
Total number of crashes= 16,370 automobile crashes
Percentage caused by distraction =28.5%
Let us find the number of crashes caused by distraction
=28.5/100* 16,370
=0.285* 16,370
=4665.45
Hence the number of crashes caused by distraction is 4665 approx
