The slope of the line containing (4,2) and (4,-3) is Infinity.

The slope of a straight line can be written as follows,

m = [tex](y_{2} -y_{1} ) / (x_{2} -x_{1} )[/tex]                  equation1

The line is containing the points  (4,2) and (4,-3). So, we can write

[tex]y_{2}[/tex] = -3 , [tex]y_{1}[/tex] = 2 , [tex]x_{2}[/tex] = 4 , and [tex]x_{1}[/tex] = 4 .

On substituting the values of variables in equation1, we will get

m = ( (-3)-(2) ) / ( (4)-(4) ) = (-6/0) = Infinity

As the slope of a line is Infinity, so we can conclude that the given line is a straight line.

Here:

m = the slope of the line

( [tex]x_{1}[/tex] , [tex]y_{1}[/tex] ) are the first coordinates.

( [tex]x_{2}[/tex] , [tex]y_{2}[/tex] )are the second coordinates.

Answer: 70,464 people

Step-by-step explanation:

         We will write an equation to help us solve. Note that a percent divided by 100 becomes a decimal and that "of" means multiplication in mathematics. Let x be the number of people who will support the measure.

96% of 73,400 voters will support the local measure.

The eighth term of the given sequence 1/2, 1/4, 1/8, 1/16, 1/32 will be 1/256.

According to the give question.

We have a sequence 1/2, 1/4, 1/8, 1/6, 1/32

Since, the first term of the given sequence is 1/2.

The second term of the given sequence is 1/4.

The third term of the given sequence is 1/8.

Here, we can see that the numerator of each term is same i.e. 1. But the denominator is changing by power or 2. For the first term it is 2^1, for the second term it is 2^2, for the third term it is 2^3 and so on.

Therefore, the gneral formula for finding the nth term of the given sequence is given by

[tex]T_{n} = \frac{1}{2^{n} }[/tex]

So, the eighth term of the given sequence is 1/2^8 = 1/256.

Hence, the eighth term of the given sequence 1/2, 1/4, 1/8, 1/16, 1/32 will be 1/256.

When two sides are provided without an angle measurement, such as a = 13m and b = 17m , we can create an infinite number of obtuse triangles.

As an example:

How many different obtuse triangles can we make if our side lengths are 13m and 17m, and our angle value ranges from 90 to 360 degrees?

Make a triangle with sides of 13m and 17m metres, a 120 degree angle, and a third side that can be protractored to the length you desire. You've constructed a triangle.

We may create a whole different triangle that is identical to this one by altering the third side's length and angle.

You must always remember to select the side lengths and angles. It's hinted that you could choose another course of action. There are an infinite amount of distinct triangles that can be created by using the same angles.

Thus, we can make an infinite number of triangles by employing a single angle and a single side length.

The total change in the stock market from the beginning of the day to the end of the day is 89.75 points.

Here, we are given that the stock market goes down 30 1/2 points at the beginning of the day.

30 1/2 can be written as-

{(30*2) + 1}/2 = 61/2

Further it is given that the stock market goes up by 120 1/4 points at the end of the day.

120 1/4 can be written as-

{(120*4) + 1}/4 = 481/4

From 125 yards, a marksman hit 55.6 of the targets last year, which is equal to (55.6 × 100)% that is 5560%

A percentage (from Latin: per centum, "by a hundred") is a number or ratio stated as a fraction of 100 in mathematics. The abbreviations "pct.", "pct.", and occasionally "pc" are also used to indicate it, while the percent symbol, "%," is most frequently employed. A percentage is a dimensionless (pure) number; it does not have a unit of measurement.

A percentage is a fraction or a ratio in which the full number is always 100. For example, if Sam received 30% on his arithmetic test, he received 30 points out of a possible 100. It is written as 30/100 in fraction form and 30:100 in ratio form.

An equation that models the balance y after x​ months is; y = -130x + 1900

From the given parameters, we can form a table of values as;

Month    Balance

0              1900

3              1510

5              1250

Now, the formula for slope between two coordinates is;

m = (y2 - y1)/(x2 - x1)

At first coordinate, we have;

m = (1510 - 1900)/(3 - 0)

m = -390/3 = -130

At second coordinate;

m = (1250 - 1510)/(5 - 3)

m = -260/2

m = -130

The slope of the line passing through the pair of points, (0 , 0) and (5 , -3), is -3/5.

The slope, m, determines the steepness of a line. It can be measured by the vertical distance from one point to another divided by the horizontal distance of the same points. The formula for solving the slope is:

m = (y2 - y1)/(x2 - x1)

where m is the slope

x1 and y1 are the coordinates of one point

x2 and y2 are the coordinates of the 2nd point

Given two points in the line, (0 , 0) and (5 , -3), plug in the values to the formula for the slope.

m = (y2 - y1)/(x2 - x1)

m = (-3 - 0)/(5 - 0)

the bacterial cell is 6.25*10 times smaller than the amoeba cell.

To find how many times smaller is the bacterial cell than the amoeba cell, we need to take the quotient between the amoeba cell's length and the  bacterial cell's length

We know that:

bacterial cell's length = 4*10^(-6) m

amoebas cell's length. = 2.5*10^(-4) m

The quotient gives:

Q = ( 2.5*10^(-4) m)/(4*10^(-6) m) = (2.5/4)*(10^(-4)*10^6) = 0.625*10^(-4 + 6)

Q = 0.625*10^2

Now we want this in scientific notation, so we need to have a digit in the left fo the decimal point, so we can rewrite this as:

Q = 0.625*10^2 = 6.25*10^1 = 6.25*10

The solution of given rational equation [tex]\frac{2}{n} +\frac{n+2}{n+1}=\frac{-2}{n^2+n}[/tex] is n = -2

In this question,

We have been given a rational equation.

[tex]\frac{2}{n} +\frac{n+2}{n+1}=\frac{-2}{n^2+n}[/tex]

We need to find the solution of given rational equation.

First we simplify the LHS of given equation.

[tex]\frac{2}{n} +\frac{n+2}{n+1}\\\\=\frac{2(n+1)+n(n+2)}{n(n+1)} \\\\=\frac{2n+2+n^2+2n}{n^2+n}\\\\ =\frac{n^2+4n+2}{n^2+n}[/tex]

So, given equation would be,

[tex]\frac{n^2+4n+2}{n^2+n}=\frac{-2}{n^2+n}[/tex]

Here, the denominator is same on the both sides.

⇒ n² + 4n + 2 = -2

⇒ n² + 4n + 4 = 0

⇒ (n + 2)² = 0

⇒ n + 2 = 0

⇒ n = -2

We need to check above solution.

so, substitute n = -2 in LHS of given equation.

[tex]\frac{2}{-2} +\frac{-2+2}{-2+1}\\\\=-1+0\\\\=-1[/tex]

Now, substitute n = -2 in RHS of given equation.

[tex]\frac{-2}{-2^2-2}\\\\=\frac{-2}{4-2}\\\\= \frac{-2}{2} \\\\-1[/tex]

For n = -2, LHS = RHS

Therefore, the solution of given rational equation [tex]\frac{2}{n} +\frac{n+2}{n+1}=\frac{-2}{n^2+n}[/tex] is        n = -2

the two lines have the same slope and different y-intercept, which means that the lines are parallel.

Two linear equations:

y = a*x + b

y = c*x + d

Are parallel only if both have the same slope, which means that c = d, and the y-intercepts are different.

And are perpendicular if the slope of one of the lines is equal to the opposite of the inverse of the other slope, so:

a = -1/c

Now, our linear equations are:

3x + 2y = 6

y = (-3/2)*x + 5

We can write both of these in the slope intercept form:

3x + 2y = 6

2y = 6 - 3x

y = (6 - 3x)/2 = 3 - (3/2)*x

y = -(3/2)*x + 3

Explanation:

x = length of the red and purple lunch box

y = length of the blue lunch box

volume = length*width*height

The volume expression for the red and purple lunch box is x*7.5*4 = 30x

Set this equal to the stated volume 300 cubic inches, and solve for x.

30x = 300

x = 300/30

x = 10

The red and purple lunch box has length of 10 inches.

-----------------

The blue lunch box has volume of

length*width*height = y*8*3 = 24y

Set this equal to 300 and solve for y

24y = 300

y = 300/24

y = 12.5

The blue lunch box has length of 12.5 inches

Therefore the blue lunch box is longer and is longer by 12.5-10 = 2.5 inches.
