The volume of a _________ is equal to ___ the volume of a cylinder that has the same base and height. The formula for the volume

of a cone is ___________________. ___ stands for the area of the _____ and ___ is the __________ of the cone. Knowing this, we could quickly find the volume of a cone that has the _______ base and height as a cylinder with a volume of 9 cubic cm. Since the volume of a cone is ____ the volume of a cylinder (with the same base and height), we would multiply 9*__ to obtain a volume of ____ cubic cm.

Answer:

cone, \frac{1}{3} , \frac{1}{3} \pi r^{2}h , \pi r^{2}, base, h, height, same, \frac{1}{3} , \frac{1}{3} , 3

Step-by-step explanation:

The volume of a cone is equal to \frac{1}{3} the volume of a cylinder that has the same base and height. The formula for the volume of a cone is \frac{1}{3}\pi  r^{2}h.  stands for the area of the base and h is the height of the cone. Knowing this, we could quickly find the volume of a cone that has the same base and height as a cylinder with a volume of 9 cubic cm. Since the volume of a cone is \frac{1}{3} the volume of a cylinder (with the same base and height), we would multiply 9*\frac{1}{3} to obtain a volume of 3 cubic cm.

Solve the following logarithmic equations.<br> log[(x^2 + 2x − 3)^4] = 0
saw5 [17]

Answer:

The solutions are x = 1.24 and x = -3.24

Step-by-step explanation:

Hi there!

First, let´s write the equation:

log[(x² + 2x -3)⁴] = 0

Apply the logarithm property: log(xᵃ) = a log(x)

4 log[(x² + 2x -3)⁴] = 0

Divide by 4 both sides

log(x² + 2x -3) = 0

if log(x² + 2x -3) = 0, then  x² + 2x -3 = 1 because only log 1 = 0

x² + 2x -3 = 1

Subtract 1 at both sides of the equation

x² + 2x -4 = 0

Using the quadratic formula let´s solve this quadratic equation:

a = 1

b = 2

c = -4

x = [-b± √(b² - 4ac)]/2a

x =  [-2 + √(4 - 4(-4)·1)]/2 = 1.24

and

x = [-2 - √(4 - 4(-4)·1)]/2 = -3.24

The solutions are x = 1.24 and x = -3.24

Have a nice day!
