Answer:
Step-by-step explanation:
y=f(x)=-5x
since x=3 just replace x with 3
y=f(x)=-5(3)
y=f(x)=-15
Answer:
Step-by-step explanation:
Given
Dimension of unpainted area:
--- Square
Required
Determine an expression to solve for x
First, calculate the area of the unpainted space;
The unpainted area, added to the painted area, equals the total area.
So, we have:
Hence, the expression is:
Answer:

Step-by-step explanation:
Answer:
4 in.
Step-by-step explanation:
The volume of the box is (8 in)(2 in)(4 in) = 64 in^3.
The formula for the volume of a cube is V = s^3, where s is the length of one side of the cube.
Setting V = s^3 = 64 in^3, we get s = 4 in.
The length of one side of the cube is 4 in.
Answer:
A. 96π in³
Step-by-step explanation:
The formula you can use to find the volume of a cone is ...
V = (π/3)r²·h . . . . where r is the radius and h is the height
Put the given numbers into the formula and do the arithmetic.
V = (π/3)(6 in)²(8 in) = 96π in³
