Answer:

The midpoint is (-1,1)

Equation: y = -x -2

Step-by-step explanation:

Midpoint:

([tex]\frac{-5+3}{2}[/tex], [tex]\frac{-5 + 3 }{2}[/tex])  You are taking the averages of the x values and the y values.

([tex]\frac{-2}{2}[/tex],[tex]\frac{-2}{2}[/tex])  

(-1,-1)

Equation:

The slope of the 2 points given is

[tex]\frac{3 - -5}{3- - 5}[/tex] = [tex]\frac{8}{8}[/tex] = 1  The slope is the change of y over the change in x.  Points are given in the form (x,y)  So, I subtracted the y values on top and the x values on  the bottom of the fraction.

The equation that is created is perpendicular to the original line, so it slope is the negative reciprocal.

1 as a fraction is [tex]\frac{1}{1}[/tex].  negative reciprocal means turn the fraction upside down and take the opposite  value.  If I flip [tex]\frac{1}{1}[/tex] upside down, I get the same fraction which is equal to 1.  Now I will take the opposite sign.  Since it is positive, the new slope will be negative

slope  -1

x = -1

y = -1  

I am using the point that will be on the new line. This is the midpoint that we just found (-1,-1)  I am going to plug in the number that I know and solve for b or the y=intercept.

y =  mx + b

- 1 = -1(-1) + b

-1 = 1 + b  Subtract 1 from both sides of the equation

-2 = b

y = mx + b

y = -1x -2

or

y = -x -2

The composition of the function, (g o h)(0) = 0.

To find the composition of a function, first, find the value of the inner function by plugging in the given value of x. The output of the inner function would now be used as the input to evaluate the outer function.

We are given the following:

g(x) = 5x

h(x) = √x

To find the composition of the function, (g o h)(0), first, find h(0). To find h(0), substitute x = 0 into the inner function, h(x) = √x:

h(0) = √0

h(0) = 0

Find (g o h)(0) by substituting x = 0 into g(x) = 5x:

(g o h)(0) = 5(0)

(g o h)(0) = 0

In order to determine what is the correct statement, calculate the amount of money Elsie can spend per month, based on her earnings per year.

Divide 45,000 by 12:

45,000/12 = 3,750

You can notice that the amount of money Elsie can spend per month is lower than the total expenses shown in the table.

Hence, the correct statement is:

C. No, because she will only make $3750 per month before taxes are taken out.

a. Median for name brands is greater than the median for store brands data values in the boxplots given.

b. Approximately 75% of the data values of name brands is greater than the median of the data values of store brands.

A boxplot displays the distribution of a data such that the median is represented by the vertical line that divides the rectangular box.

25% of a data distribution is represented by the beginning of the edge of the box, while 50% is represented by the median, and 75% is represented by the point at the end of the edge of the box in the boxplot.

Therefore:

a. The median of name brands peanut butter is approximately 82-83.

The median of store brands is approximately less than 80.

Thus, we can conclude that, the median for name brands is greater than the median for store brands.

b. The median for store brands is approximately below 25% of the data values for name brands. Therefore, we would conclude that, approximately 75% of name brands data value are greater, compared to the median of the store brands data value.

y² = -8(x - 4),  which is the required equation of the parabola.

All points in a plane that are equally spaced out from a given point and a given line make up a parabola.

The line is known as the directrix, and the point is known as the parabola's focus.

A parabola's axis of symmetry is perpendicular to the directrix, which does not touch the parabola.

The focus of the parabola is F(-6,0) and its directrix is the line x=−2 i.e., x+2=0

Let P(x,y) be any point in the plane of directrix and focus, and MP be the perpendicular distance from P to the directrix,then P lies on parabola if FP=MP

ANSWER:

Given:

radius of Ferris wheel = 40 ft

height of a car = 5 ft

height of a tent = 20 ft

no. of passenger cars = 20

time to load all cars = 12 minutes

time for 1 rotation = 2 minutes

time for all rotations = 8 minutes

What we want to know is how many degrees the car will have to travel along the circle before it reaches a height of 20 ft.

We can draw a triangle to represent the unknown and find the angle.

The total height from the ground to the center of the Ferris wheel is 45 ft (5ft car height + 40 ft radius). We deduct the 20ft height of the tent so we get the side of the right triangle we're using to solve for the missing angle. That height is 25 ft.

The radius also serves as the hypotenuse of the triangle.

We can then use the following to solve for the angle theta:

Now we know that the car must travel 51.3 degrees along the circle before it gets to a height where it can see above the tents. If one rotation is 360 degrees and it takes 2 minutes to complete one round, then to find the time it will take to travel 51.3 degrees, we use the following equation:

It will take them 17.1 to be able to start looking for their house.

Now every time the car goes around the path of the Ferris wheel, for 17.1 going up and another 17.1 seconds going down, they will not be able to look for their house.

17.1 seconds x 2 x 4 turns = 136.8 seconds

8 minutes - 136.8 seconds = 480 - 136.8 = 343.2 seconds or 5 minutes and 43.2 seconds

Firstly, let us define natural numbers.

Natural numbers are simply positive intergers, that is integers that are greater than zero e.g 1,2,3,4...

Secondly, when is a set said to be closed under a particular operation?

A set is said to be closed under an operation if and only if the operation on any two elements of the set produces another element of the same set. for example when you perform an operation (like addition) on a set of number (like natural numbers) it must give you a number from that same set.

E.g

let's check whether natural numbers are closed under the operation of adddition.

taking two numbers 3 and 5.

since the operation gives us 8, which is a natural number, it means natural numbers are closed under the operation of addition.

Back to the main question, which is to check whether natural numbers are closed under the operation of subtraction.

taking two cases.

case 1; taking numbers 3 and 5

case 2: taking numbers 7 and 2

From the two cases, case 2 gave us a natural number while case 1 does not give us a natural number.

This means that Natural numbers are not Closed under subtraction.

Because subtraction operation on natural numbers does not necessarily produce another natural number.

On a general note;

Natural numbers are closed under Addition and Multiplication operations

while They are not closed under subtraction and division operation

Answer: Number of children = 112, number of adult = 140

Let the number of children = x

Let the number of adult =

According to the question, 252 people entered the park

Mathematically, the number of adult and children that entered the park sum up to 252

x + y = 252 ------- equation 1

$1.5 is charged for children for the admission fee into the park

$4 is charged for adult for the admission fee into the park

A totaled of $728 was realized from both children and adult that were admitted into the park

This implies that the total amount realized is equal to the number of children and adults inside the park per amount charged respectively

1.5* x + 4 * y = 728

1.5x + 4y = 728 -------- equation 2

Equation 1 and 2 can be solve simultaneously using substitution method

x + y = 252 ----- 1

1.5x + 4y = 728 ------ 2

Make x the subject of the formula in equation 1

x + y = 252

x = 252 - y ----- equation 3

Substitute equation 3 into equation 2

1.5(252 - y ) + 4y = 728

Open the parenthesis

1.5 x 252 - 1.5 x y + 4y = 728

378 - 1.5y + 4y = 728

Collect the like terms

-1.5y + 4y = 728 - 378

2.5y = 350

Divide both sides by 2.5

y = 350/2.5

y = 140

To find x, put the value of y into equation 1

x + y = 252

x = 252 - y

x = 252 - 140

x = 112

The number of children = 112

The number of adults = 140
