Step-by-step explanation:

In rational functions, the discontinuities are caused by the denominator terms. Since the denominator of a fraction is non-zero, any term multiplied by the denominator is also non-zero.

To find the discontinuities, we need to factor the polynomial below. Once we have the two binomials, we set each to 0. This way, you can find the value that produces 0 in the denominator.

If x = -2 then (x^2) + 4 is 0.

So, the discontinuities are shown as x = -2

Write an equation of the line with the given slope and y -intercept. Use slope-intercept form. Then rewrite the equation in standard form. m=3, b=-7

How to write the equation in slope-intercept form?

Given:

m=3(slope)

b=-7(y -intercept)

The slope-intercept form is given by,

y=mx+b

y=3x-7

Thus, y=3x-7 is the slope-intercept form.

How to rewrite the equation in standard form?

Standard form is given by,

Ax+By=C

Since, slope-intercept form is y=3x-7

⇒3x-y=7

Thus,3x-y = 7  is the standard form.

Step-by-step explanation:

Wayne bought 72 ounces of blueberries.

A fraction is a non-integer that is made up of a numerator that is divided by a line from the denominator. An example of a fraction is 1/2. 1 is the numerator and 2 is the denominator.

The first step is to determine the total fraction of blueberries that was used.

[tex]\frac{3}{8} + \frac{1}{6} + \frac{5}{12}[/tex]

[tex]\frac{27 + 12 + 30}{72}[/tex] =  [tex]\frac{69}{72}[/tex]

Ounces of blueberries he bought = (ounces used ÷  fraction of blueberries used)

69 ÷  [tex]\frac{69}{72}[/tex]

69 x 72/69 = 72 ounces

According to the question, every morning Sally takes same bus and she has to wait to arrive with the used method called as uniform distribution.

And the range of the interval is as: min = 0 and max = 10.

For the calculation of the uniform distribution, the height some be constant.

Now, using standard uniform distribution formula:

Mathematically, the function  f(x) can be written as:

f(x) = 1/(b - a)

where, 'a' and 'b' are defined intervals. Here, a = 0; b = 10.

Now, to calculate the percentage form the area as a rectangular grid which means:

f(x) = 1/10(5.3 - 2.5) = 2.8/10 = 0.28 = 28 percent.

Now, to know the percentile using above data:

f(x) = 1/(b - a) = 7/10 = 0.7 = 70 percent.

The values for the variables 'x' and 'y' are (3,7).

According to the question, to calculate the value of 'x' and 'y' then equate both the equations.

The given expressions are:

Equation (1): x + (1/7)y = 4 ⇒ 7x + y = 28

Equation (2): y = 3x - 2

Solving equation (1) and equation (2) by substituting the value of the 'y':

Therefore, 7x + 3x - 2 = 28 ⇒ 10x = 30 ⇒ x = 3

Now: y = 3(3) - 2 = 7

Hence, the values are: x = 3 and y = 7.

The ratio of the volumes of the Spaceship Earth to a golf ball = 1926949795 : 1

We need to find the volumes of the Spaceship Earth and a golf ball.

Spaceship Earth

Radius, R = 165/2 ft = 82.5 ft

Volume of the Spaceship Earth = [tex]\frac{4\pi R^3}{3}[/tex] = (4 x 3.14 x 561515.625)/3

                                                    = 2350878.75 cubic ft.

A golf ball

Radius = 1.5/2 inches = 0.75 inches

1 ft = 12 inches

So 0.75 inches = 0.75/12 = 0.0625 ft.

So radius, r = 0.0625 ft

Volume of a golf ball =  [tex]\frac{4\pi r^3}{3}[/tex] = (4 x 3.14 x [tex]0.0625^3[/tex])/3

                                   = 0.00122 cubic ft.

Ratio of the volumes of Spaceship Earth to a golf ball

                    = 2350878.75:0.00122

                    = 1926949795 : 1

  Rationalization is a mathematical operation that allows us to determine or eliminate a root of the denominator of a fraction, so that it can be expressed in linear form, either decimal or integer, by the product of a root.

  As defined above, we must perform a mathematical operation to eliminate the root of the denominator without altering the value.

Using Pythagorean theorem, the student walked 53.58 meters more compared to the total displacement from the starting point.

If a student walks 100 meters north, then 100 meters west, then the path he travels resembles the sides of a right triangle (see attached photo).

Using Pythagorean theorem, we can solve for the total displacement from the starting point to the end point.

c^2 = a^2 + b^2

where c is the total displacement from the starting point to the end point

a is the distance he walks up north

b is the distance he walks to the west

c^2 = 100^2 + 100^2

c^2 = 10,000 + 10,000

c^2 = 20,000

c = 141.42 meters

Comparing the total distance the student walked and the total displacement from the starting point to the end point by subtraction.

100 meters + 100 meters - 141.42 meters = 53.58 meters

If Mohammad leaves home walks 5 blocks to the library and he then walks 2 blocks toward home to meet up with his friend and then together, he and his friend walk to the library together, then Mohammad walked for 9 blocks.

To calculate how far Mohammad walked we use addition.

Total blocks Mohammad walked = blocks to the library + blocks towards home to meet up with friend + blocks back to the library together

blocks to the library = 5

blocks towards the home to meet up with friend = 2

blocks back to the library together = 2 (As he walked 2 blocks towards home from the library, he will walk the same number of blocks again to reach the library)

Therefore,

total blocks Mohammad walked = 5 + 2 + 2

total blocks Mohammad walked = 9

Hence, the number of blocks Mohammad walked for is calculated to be 9.

Vertically Stretching and Compressing

Multiplying a function by positive constant yields a function whose graph is vertically stretched or compressed relative to the original function's graph. If the constant is greater than 1, it will stretch vertically. If the constant is between 0 and 1, vertical compression is done. You get vertical compression.

Vertical compression occurs when you multiply the function by a rational scaling factor. The base of the function graph remains the same even when the graph is compressed vertically. Only initial values ​​are affected.
