Answer:
D(V) = 100,48 cm³
Step-by-step explanation:
The volume of a sphere is:
V(s) = 4/3 π*r³
Where r is the radius of the sphere
If we take derivative of V respect r
D(V)/ dr = 4/3*3*π*r² ⇒ D(V)/ dr = 4*π*r² ⇒ D(V) = 4*π*r²*dr
We know:
r = 20 cm and dr = 0,02 ( at most)
Then
D(V) = 4*π*(20)²*0.02 cm³
D(V) = 32*π
D(V) = 100,48 cm³
Answer: he collected 22 quarters and 8 fifty-cent pieces
Step-by-step explanation:
Given;
The total amount of money he is to collect is;
A = 20 - 10.50 = $9.50
Let x represent the number of quarter he collected.
Then the number of fifty-cent pieces he collected will be; 30-x
Therefore we can represent it with the equation below;
0.25x + 0.50(30-x) = 9.50
0.25x + 15 - 0.50x = 9.50
0.25x = 15-9.50
x = (15-9.50)/0.25
x = 5.50/0.25
x = 22
The number of fifty-cent is equal to;
30-x = 30-22 = 8
Therefore, he collected 22 quarters and 8 fifty-cent pieces
Answer:it’s b
Step-by-step explanation:
Answer: 
or ![y=\sqrt[3]{8x} -1](https://tex.z-dn.net/?f=y%3D%5Csqrt%5B3%5D%7B8x%7D%20-1)
Step-by-step explanation:
To find the inverse, you switch y with x and x with y. Then, you solve for y.
[switch y with x and x with y]
[multiply both sides by 8]
[cube both sides]
![\sqrt[3]{8x} =y+1](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B8x%7D%20%3Dy%2B1)
[subtract both sides by 1]
