Answer:

Angle 6 is 78 degrees Angle 7 is 102 degrees

Step-by-step explanation:

Since both lines are parallel, you can assume that Angle 6 plus Angle 7 are a linear pair. Angle 1 corresponds to Angle 5 by the corresponding parts. Angle 5 is congruent to Angle 7 by Vertical angles so therefore Angle 7 is 102. Since Angle 6 + Angle 7 equal 180 degrees, you can put the equation like this,

[tex]Angle 6 + 102 = 108. Angle 6 = 78.[/tex]

Step-by-step explanation:

The x-intercept and y-intercept of the equation will be (-1, 0) and (0, 2). The graph is given below.

A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.

The linear equation is given as,

x/a + y/b = 1

Where 'a' is the x-intercept of the line and ‘b’ is the y-intercept of the line.

The linear equation is given below.

y = 2x + 2

Convert the equation into intercept form, then we have

y = 2x + 2

Dr. Ellison's equation that f(2) = 5/3 is wrong

From the question, we have the following equation that can be used in our computation:

y = -3x + 7

This equation can be expressed as a function

So, we have

f(x) = -3x + 7

In Dr. Ellison's equation, we have

f(2) = 5/3

This means that

x = 2

So, we have

f(2) = -3 * 2 + 7

Evaluate

f(2) = 1

The calculated value is different from Dr. Ellison's equation

Hence, the solution is wrong

There are 33 numbers that are less than 200 and divisible 4 but not divisible 12. this can be solved with the help of simplification.

What is simplification?

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Main body:

Given that,

To determine how many natural numbers less than 200 are divisible by 4, but not divisible by 12.

Here,

Let the largest number divisible by 4 less than 200 is 198

The total numbers divisible by 4 and less than 200 is,

= 198 / 4 = 49

Similarly

The total number divisible by 12 and less than 200 is,

= 192/ 12 = 16

So the numbers that are less than 200 but divisible 4 not by 12 is,

= 49 - 16

= 33

Hence, there are 33 numbers that are less than 200 and divisible 4 but not divisible 12.

For the given fees charged by two fitness clubs , number of months required by two fitness clubs to pay the same total amount is equal to      10 months.

As given in the question,

Number of fitness club  = 2

Let 'x' represents the number of months

Charges for a month membership charged by Mike's Fitness center is equal to $30.

Charges for a month membership charged by All-Day Fitness club is equal to $22 plus $80 initiation fee.

Required equation when two clubs have same amount of charges is given by:

30x = 22x + 80

⇒ 30x -22x = 80

⇒ 8x = 80

⇒ x = 10 months

Therefore, number of months required by two fitness clubs to pay the same total amount is equal to 10 months.

The complete question is:

Mikes fitness center charges $30 per month for a membership. All-Day fitness club charges $22 per month plus an $80 initiation fee for a membership. After how many months will the total amount paid to the two fitness clubs be the same?

Watkins family should install a chlorine pool because it is more cost effective because the y-value at 10 years is less on graph B than it is on graph A.

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

If the family plans to move to their retirement home in 10 years, We need to find which pool would be more cost effective to install.

As in the given graph, the x-axis denotes the year while the y-axis denotes the cost of maintaining the pool in that year.

When we compare the two of the given graph we will find the cost of maintaining a chlorine pool is less as compared to a salt water pool at x=10, therefore, after 10 years.

Hence, the Watkins family should install a chlorine pool because it is more cost effective because the y-value at 10 years is less on graph B than it is on graph A.

A. The equation that can be used to determine the number of weeks is $999=225+42w

B. The number of weeks it will take Hannah to repay is 18weeks

An equation is a mathematical statement, which has an equal sign (=) between the algebraic expression. Linear equations are the equations of degree 1. It is the equation for the straight line. The solutions of linear equations will generate values, which when substituted for the unknown values, make the equation true. In the case of one variable, there is only one solution. For example, the equation x + 3 = 0 has only one solution as x = -2.

the total amount of money Hannah repaid is $225+$43×w, where w is the number of weeks to repay $43.

therefore $999= $225+$43w

$43w=$ (999+225)

$43w= $1224

divide both side by $43

w= $1224/$43

w= 18 weeks

therefore it will take Hannah 18weeks to repay the money.

The ball hits the ground after x = 6 seconds.

Two or more expressions with an equal sign are defined as an equation.

The given equation is h(x) = -2x² + 8x + 24.

(a) when the ball is thrown, the time is t = 0 sec.

Therefore, the height of the ball when it is thrown is,

h(0) = -2(0)² +8(0) +24

h(0) = 24

(b) The derivative of the function is,

h'(x) = -4x + 8

Substitute h'(x) = 0 into the above equation,

0 = -4x +8

4x = 8

x = 2

The second derivative of the function is,

h''(x) = -4

Since the second derivative of the function is negative, the function is maximum at x = 2.

(c) The maximum height of the ball is,

h(2) = -2(2)² + 8(2) +24

h(2) = -8 +16 +24

h(2) = 32

(d) The ball hits the ground when h(x)= 0, therefore,

0 = -2x² +8x +24

0 = -2x² +12x - 4x + 24

0 = -2x(x - 6) - 4(x - 6)

0 = (x - 6)(-2x - 4)

(x - 6) = 0 or (-2x-4) = 0

x = 6 or x = -2

Since time cannot be negative, it follows, x = 6 seconds.

Hence, the ball hits the ground after x = 6 seconds.

The linear model that represents the total cost of recording is f(x) = 75x + 50.

The initial fee is $50 for recording an album.

There is an additional cost per hour i.e. $75.

number of hours = x

Now based on the above information, the linear model should be f(x)=75x+50

Here 50 represent the initial fee i.e. equivalent to y-intercept

And, 75 represent the slope

Therefore we can conclude that the linear model that represents the total cost of recording is f(x) = 75x + 50.
