Hello,
if f(x)=y=x+3
x=y+3==>y=x-3
f^(-1) (x)=x-3 is the inverse function of f(x).
Answer:
5
Step-by-step explanation:
We cannot repeat an x value for the relation to be a function
Since x=3 ,4, 7 are already used
We must let x=5
The correct answer is the second answer choice. It is the one that starts with (0,-2).
Answer:
The approximate volume of the tube is 1,005 cm³
Step-by-step explanation:
To find the volume of the tube, we will follow the steps below:
First, write the formula for calculating the volume of a cylinder
volume of a cylinder = πr²h
where r is the radius and h is the height of the cylindrical cardboard tube
from the question given, height is equal to 20 centimeters and diameter = 8 centimeters but diameter = 2r, this implies that r = d/2 hence radius r =8/2 = 4 centimeters
π is a constant and is ≈ 3.14
we can now proceed to insert the values into the formula
volume of a cylinder = πr²h
≈ 3.14 × 4²× 20
=3.14 × 16× 20
≈1,005 cm³ to the nearest whole cubic centimeter.
The approximate volume of the tube is 1,005 cm³
