We can solve a quadratic equation by factoring only if always the equation is in the form "(quadratic expression) equals (zero)".

We need to use the following steps to solve the quadratic equation by factoring:

Step 1. Place the quadratic expression on one side of the "equals" sign, with zero on the other side.

Step 2. Factor the given quadratic expression into its two linear factors.

Step 3. Put each of these linear factors equal to zero, forming two linear equations.

Step 4. Solve the two linear equations.

For example, Solve (x − 2)(x − 4) = 0 by factoring.

x − 2 = 0   or   x − 4 = 0

x = 2   or   x = 4

x = 2, 4

Answer: The measure of an angle is the same as the measure of its reference angle in the first or fourth quadrant. Since, m∠884° is in the 8th quadrant, we can use the reference angle in the first quadrant, which is m∠4°.

So, m∠1 = m∠4°

To find the measure of the angle m∠3, we can use the fact that angles in different quadrants that share a terminal side have measures that add up to 180°.

m∠3 = 180° - m∠1

m∠3 = 180° - m∠4°

m∠3 = 180° - 4° = 176°

Therefore, m∠1 = m∠4° and m∠3 = 176°.

The volume of the picnic basket is 1920in^3.

If the prism is such that if we slice it horizontally at any height smaller or equal to its original height, the cross section is same as its base, then its volume is:

[tex]V = B \times h[/tex]

where h is the height of that prism and B is the area of the base of that prism.

Given;

The height of the basket is 8 inches

The bottom of the basket has an area of 240 square inches.

Now,

V=B x h

V= 8 x 240

V= 1920

We must calculate the ratio between two successive phrases in order to perform the ratio test:

The nth term is n / 3n.

The (n + 1)th term is (n + 1) / 3n + 1.

The ratio test:  lim |   [ (n + 1) / 3n + 1 ]  /  [  n / 3n ]   |

                =    lim |    [ (n + 1) / n ]  ·  [ 3n  / 3n + 1 ]   |

                =    lim |    [ (n + 1) / n ]  ·  [  1/3  ]   |

                =   (1/3) · lim |  (n + 1) / n  |

                =   (1/3) · lim |  ( n/n ) + (1/n)  |

The table that shows a proportional relationship is Table D.

Please find attached the graph of Table D created with MS Excel

The variables x and y in a set of ordered pair (x, y), are proportionally related, when the ratios of the x and y values for of all data points in the set are equivalent, such that a proportional relationship can be expressed in the form; y = k·x

Where;

k = The constant of proportionality

Therefore; k = y/x

The ratio of the y-values to the corresponding x-values in the table that shows a proportional relationship is therefore a constant.

Analyzing the Table C, we get;

The points are; (2, 1), (4, 3), (6, 5), (8, 7)
x/y for each data point is therefore;

1/2 ≠ 3/4 ≠ 5/6 ≠ 7/8

Table C does not show a proportional relationship

The coordinate points in Table D are; (2, 1), (6, 3), (8, 4), (10, 5)

The ratio, x/y at each point in the table are therefore;

1/2 = 3/6 = 4/8 = 5/10 = 1/2

The ratio, x/y at each point in the table is constant, therefore, Table D ahows a proportional relationship.

Answer:Equilateral triangle

Step-by-step explanation:The following are the important points that should be remembered while classifying the triangles. All triangles have two acute angles. The sum of internal angles is always 180 degrees. In an equilateral or equiangular triangle, each angle is 60 degrees. Identify the type of the triangle, if one of its angles is 100° based on the type of triangle.

So, the midpoint is at a ratio of 1/2 of the way from the first point to the second point on both x and y axis.

The ratio used to find the midpoint of a line segment is 1:1 or 1/2:1/2.

To find the midpoint of a line segment, we need to average the x-coordinates and the y-coordinates of the two given points.

The x-coordinate of the midpoint = (x1 + x2)/2

The y-coordinate of the midpoint = (y1 + y2)/2

So we can say that the midpoint is at a ratio of 1/2 of the way from the first point to the second point on both x and y axis.

The line with m as the slope, m and c as the y-intercept is the graph of the linear equation y = mx + c. The values of m and c are real integers in the slope-intercept form of the linear equation.

Using the slope and y-intercept, draw an equation as follows.

1. To solve for the y-intercept in the equation y = mx + b.

2. Draw the y-intercept on a graph. The purpose will be (0, b).

The value of w is 100

A linear equation only has one or two variables. No variable in a linear equation is raised to a power greater than 1 or used as the denominator of a fraction.

Example of linear equations are 5x +2 = 7. This is an example of linear equation with one variable. Example of linear equation with two variables is :

5x+2y = 3 and 7x+6y = 5.

Where x and y are the variables.

Similarly , 35 = 0.35w is an example of linear equation with one variable , here the variable is w. And to find the value if the variable we divide both sides by the coefficient of w.

Therefore, divide both sides by 0.35

35/0.35 = w

The most typical teaser in sports betting is a 6-point football teaser, which requires you to correctly predict the results of two games while also receiving six extra points on each spread.

It will pay about -120 depending on the book. Some bookies pay roughly 6-1 for a two-team, six-point pleaser. In order to break even, bettors must win each leg around 38% of the time.

Make sure your 6-point, two-team teasers pay -120 or greater. If you're not being treated fairly there, you most likely won't be on other teasers either.

Penelope would have to pay 11.80 for a mug with her own name on it. the fixed cost would be 5.40 and cost per letter would be 0.80.

Total cost = Fixed cost + (no. of letters*cost per letter)

let us take the fixed cost as x and cost per letter as y

so for alexander,

12.60 = x + 9y (eq 1)

for lucia,

9.40 = x + 5y (eq 2)

equating eq1 and eq 2

12.60 - 9y = 9.40 - 5y

12.60 - 9.40 = - 5y + 9y

4y = 3.20

y = 0.80

x = 9.40 - 5y

= 9.40 - 4 = 5.40

Total number of Attendants in a certain conference are 54

There are 24 psychiatrists and 30 psychologists

Total number of attendants = 24 + 30= 54.

Therefore total number of cases is 54

1 ) Since there are 30 psychologists, the number of favorable outcomes is 30.

So P ( 30 psychologists) =Number of favorable cases/ Total number of cases

An algebraic expression known as a polynomial requires that all of its exponents be whole numbers. Any polynomial must have variable exponents that are non-negative integers. Although a polynomial contains variables and constants, we are unable to divide a polynomial by a variable.

Properties of a right angle triangle:

One of its angles is equals to 90 degrees

The sides of the triangles can be calculated using Pythagoras theorem.

Therefore, let's find the height of the building and the radio antenna from the eye point.

Using trigonometric ratios,

tan 35° = opposite / adjacent

tan 35° = x / 28

where

x = the height of the building and the radio antenna from the eye point.

x = 28 tan 35

x = 28 × 0.700207

x = 19.60581 meters

Let's find the height of the building from his eye point.

tan 32° = y / 28

where

y = height of the building from his eye point

y = 28× tan 32°

y = 28 × 0.6248693

y = 17.496341 meters
