If (7^0)^x = 1, what are the possible values of x?

1 answer:

5 0

(7^0)^x = 1

7 power zero is 1.

(1^x) = 1

So x can be any value.

x could be, -2, -3, 1, 0, 3, 5, 1.8, -1.5,

x could be any number positive or negative or even zero.

The height of a cylinder is twice the radius of its base.

Ber [7]

Let x represent radius of circle.

We have been given that the height of a cylinder is twice the radius of its base. So height of cylinder would be $2x$ .

Now we will use volume of cylinder formula to our given problem.

$V=\pi r^2h$ , where,

r = Radius of base of cylinder,

h = Height of cylinder.

Upon substituting our given values, we will get:

$V=\pi\cdot x^2\cdot 2x$

$V=2x^3\pi$

Therefore, our required volume expression would be $2x^3\pi$ .

George is throwing a party for his son's 9th birthday he orders for sandwiches to the party if each person will eat 2/3 of a san

ddd [48]

Answer:

George can feed 6 people.

Step-by-step explanation:

Given:

Number of sandwiches = 4

Each person eats two-third of a sandwich.

Therefore, number of persons eating 4 sandwich is given as:

$\textrm{Number of persons} =\frac{\textrm{Total sandwiches eaten}}{\textrm{Total sandwiches eaten by 1 person}}$

Therefore,

$\textrm{Number of persons} = \frac{4}{\frac{2}{3}}\\\\\textrm{Number of persons} =4\times \frac{3}{2}=6$

|3x-7|-7=x solve the equation for all values of x

romanna [79]

The solutions to the given equation containing absolute value term |3x-7| - 7 = x are 0 and 7.

<h3>What are the solutions to the given equation?</h3>

Given the equation in question;

|3x-7| - 7 = x

First, add 7 to both sides.

|3x-7| - 7 + 7 = x + 7

|3x-7| = x + 7

Next, remove the absolute value term, this creates a ± on the right side of the question.

|3x-7| = x + 7

3x-7 = ±( x + 7 )

The complete solution is the result of both the negative and positive portions of the solution.

For the first solution, use the positive of ±.

3x-7 = ( x + 7 )

3x - 7 = x + 7

3x - x = 7 + 7

2x = 14

x - 14/2

x = 7

For the second solution, use the negative of ±.

3x-7 = -( x + 7 )

3x-7 = -x - 7

3x + x = -7 + 7

4x = 0

x = 0/4

x = 0

Therefore, the solutions to the given equation containing absolute value term |3x-7| - 7 = x are 0 and 7.
