Answer: pi (3.14)

Step-by-step explanation:

The circumference formula is pi*radius squared. Radius is half the diameter so radius is 1.

1 squared is still 1.

The answer is 3.14 or pi

Answer:

300 [tex]m^{2}[/tex]

Step-by-step explanation:

The spread has a rate of 25 [tex]m^{2}[/tex] per every 1/6 hour.  That can be expressed as   25 [tex]m^{2}[/tex] per every 1/6 hour:

25 [tex]m^{2}[/tex]/ (1/6 hour), or

150 [tex]m^{2}[/tex]/hour

After 2 hours, the spread would be (150 [tex]m^{2}[/tex]/hour)*(2 hours) = 300 [tex]m^{2}[/tex]

Answer:

Answer: the answer to your question is 8.0

Step-by-step explanation:

Sin theta = opposite /hypotenuse sin 53 = x/10

Multiply each side by 10

10 sin 53 = x

To the nearest tenth

x = 8.0

Answer:

SO this equation is y={4-3x}

This is an absolute value so the domain is all real numbers

For this equation, we are shifting left 3 and up 4

The vertex is (1,1) Turning point

Points:
(-1,7)

(0,4)

(1,1)

(2,2)

(3,5)

(4,8)

It will make a v shape

(if u were too do this on the ti-84, hit y=, then hit 2nd catalog and hit abs, plug in the equation; then hit 2nd graph to get the table. You will need to find the vertex by finding the number at which they are not the same)

|3x−4|<6x

Let's find the critical points of the inequality.

|3x−4|=6x

We know either3x−4=6xor3x−4=−6x

3x−4=6x(Possibility 1)

3x−4−6x=6x−6x(Subtract 6x from both sides)

−3x−4=0

−3x−4+4=0+4(Add 4 to both sides)

If the function is translated 4.5 units to the left to createe the graph of function g(x), hence the resuting function will be g(x) = (x + 4.5)^2

Given the function expressed as
f(x) = x^2

If the function is translated 4.5 units to the left to createe the graph of function g(x), hence the resuting function will be:

g(x) = (x + 4.5)^2

Note that translation to the left means addition of the factor

Answer:39 hours

Step-by-step explanation:First, let's find the rate of money per hour:$554.30 / 23 hour= $24.1 / 1 hourDaniel earns $24.10 every hour he works.To find the hours that Daniel has to work to earn $939.90, divide it by 24.10:$939.90 / 24.10= 39Now, we can check:$24.10 * 39= $939.90

The cost would be the same for Justin and Bella if 500 checks are sold, costing about $200.

An equation is an expression that shows the relationship between two or more variables and numbers.

Given the equation for Bella:

c = 0.1n + 150

Where C is the monthly cost for n checks.

For Justin:

1.2 = 3k

k = 0.4

C = 0.4n

To have the same cost:

0.1n + 150 = 0.4n

n = 500

c = 0.4(500) = 200

The cost would be the same for Justin and Bella if 500 checks are sold, costing about $200.

The correct answer is the inverse matrix: [ 1 -3 2]

                                                                      [ 2 -5 3]

                                                                      [-1 3 -2]

To find the inverse matrix that can be used to solve the given system of equations, we need to represent the system in matrix form as AX = B, where A is the coefficient matrix, X is the column matrix of variables, and B is the column matrix of constants.

The given system of equations can be written as:

[1 -1 -1] [x] [ 4]

[-1 2 3] * [y] = [-2]

[ 1 1 4] [z] [10]

To find the inverse matrix, we'll set up the augmented matrix [A | I], where I represents the identity matrix:

[1 -1 -1 | 1 0 0]

[-1 2 3 | 0 1 0]

[1 1 4 | 0 0 1]

Using Gaussian elimination, we'll perform row operations to transform the left side into the identity matrix, while applying the same operations to the right side. The resulting matrix on the right side will be the inverse matrix.

After performing the row operations, the augmented matrix becomes:

[1 0 0 | 1 -3 2]

[0 1 0 | 2 -5 3]

[0 0 1 | -1 3 -2]

Therefore, the inverse matrix is:

[ 1 -3 2]

[ 2 -5 3]

[-1 3 -2]

Hence, the correct answer is the inverse matrix:

[ 1 -3 2]

[ 2 -5 3]

[-1 3 -2]

Answer:

3080

Step-by-step explanation:

Let us set up some variables:

Now let us set up some equations based on the facts:

Equations:

   L = 4W     -- equation 1

   2L + 2W = 80 -- equation 2

   Plug the value of L from equation 1 into equation 2

    2(4W) + 2W = 80

     8W + 2W = 80

        10W = 80

           W = 8 -- equation 3

   Plug the value of W from equation 3 into equation 1:

    L = 4W = 4 * 8 = 32

Therefore the length is 32 and the width is 8.
