Measure of each of the angles formed between ZAOB is 71° using angle bisector theorem.

In geometry, an angle bisector is a line that divides an angle into two equal angles. The term "bisector" refers to a device that divides an object or a shape into two equal halves. An angle bisector is a ray that divides an angle into two identical segments of the same length.

m(ZAOB)=142°

OX will bisect ZAOB in equal angel both side.

So m(ZAOX) is 71°

And also, m(ZAOB) is 71°

Analyze the different intervals at which the function takes the values provided by the graph. Pay special attention on the circles, whether they are filled up or not.

From the graph, notice that the function takes the value of 3 when x is equal to -4, -2 or any number between them. Therefore, the condition is:

If x is greater (but not equal) than -2 and lower or equal to 3, the function takes the value of 5. Therefore:

Finally, the function takes the value of -3 whenever x is greater (but not equal) to 3 and less than or equal to 5. Then:

In the equation y = 4x + 62, the increasing rate is 4

If the actual rate decreases at the rate they were expected to increase, then it is -4 instead of 4.

Then, the equation of the line is:

B) y = - 4x + 62

By solving the equation 5x + 12 = -2, the value of x in is -2.8

Solution

5x = -2-12

5x = -14

We get -14

x = -14 ÷ 5

x = -2.8

Hence, by solving the equation 5x + 12 = -2, the value of x in is -2.8

The amount for social security for all 3 months will $930 and the contribution for Medicare will be $217.5.

Given that the salary exists paid in US dollars, we can consider that Renae Walters falls under the social security and Medicare tax rates for the United States. These rates, as of 2020, fall at 6.2% for social security and 1.45% for Medicare.

Social security contribution = Social security tax rate × Income earned

January for example Social Security = 0.062 × $15,000 = $930    

Medicare contribution = Medicare tax rate × Income earned

January for example Medicare = 0.0145 × $15,000= $217.5

The required equation has the same solution as 2.3p – 10.1 = 6.5p – 4 – 0.01p is 230p – 1010 = 650p – 400 – p.

Equivalent expressions are even though they appear to be distinct, their expressions are the same. when the values are substituted into the expression, both expressions produce the same result and are referred to be equivalent expressions.

We have the given expression below:

⇒ 2.3p – 10.1 = 6.5p – 4 – 0.01p

Convert the decimal into a fraction to get

⇒ (23/10)p – (101/10) = (65/10)p – 4 – (1/100)p

⇒ (23p – 101)/10 = (650p – 400 – p) /100

⇒ 230p – 1010 = 650p – 400 – p

As a result, the equation that has the same answer as 230p – 1010 = 650p – 400 – p.

To determine the equation of the line you need to determine its slope first.

You know that the line 6y=x-12 is perpendicular to the line you have to determine, two lines that are perpendicular, their slopes are opposite reciprocals. For example, let "m" represent the slope of one of the lines and "n" represent the slope of the perpendicular line, you can express their relationship as follows:

To determine the slope of the given line, you have to write it in slope-intercept form:

Where

m represents the slope

b represents the y-intercept

Given the line:

-Divide both sides by 6

The slope of this line is the coefficient of the x-term, n=-1/6

Its opposite reciprocal is:

The slope of the line you have to determine is m=6

Now that you have the slope of the line, using the point-slope form, you can determine the equation of the line:

Where

m represents the slope of the line

(x₁,y₁) represent the coordinates of one point of the line

Replace the formula with m=6 and (x₁,y₁)=(4,-7)

The next step is to write the equation in slope-intercept form:

-Distribute the multiplication on the parentheses term:

-Pass "+7" to the right side of the equation by applying the opposite operation "-7" to both sides of it:

Finally, write the equation of the line using function notation:

First, we need to find out how many possible combinations of pizza toppings there would be.

To do this, we will use the formula for Combination.

Combination is all the possible arrangements of things in which order does not matter. In our example, this would mean that a pizza topped with spicy Italian sausage, banana pepper, and beef is the same as a pizza topped with banana pepper, beef, and Italian sausage.

The formula for combination is

From our given, n would be 17, since there are a total of 17 toppings (including spicy Italian sausage, banana peppers, and beef) and r would be 3 since there are three toppings that you chose.

Substituting it in the formula,

Now, since we know that there are a total of 680 combinations of pizza toppings, we can now solve the probability of the first winner selecting a pizza topped with Italian sausage, banana peppers, and beef.
