Can I Get Some Help On This Please?Options 1: Reflection Accross The Y-axis, 90 Degree Counterclockwise

Answers

Answer 1

Answer:

The sequence of transformation that can be performed on quadrilateral ABCD to show that it is congruent to quadrilateral GHIJ is a 90 degrees counterclockwise rotation about point A followed by reflection across the y-axis and a translation of 20 units down.

Explanation:

The sequence of transformations are described in the following figure:

Therefore, the first transformation is a rotation of 90 degrees counterclockwise about point A. After that transformation, we get the figure A'B'C'D'

Then, we reflect the figure across the y axis, so we get A''B''C''D''

Finally, we translate the figure 20 units down to get GHIJ

So, the answers are:

The sequence of transformation that can be performed on quadrilateral ABCD to show that it is congruent to quadrilateral GHIJ is a 90 degrees counterclockwise rotation about point A followed by reflection across the y-axis and a translation of 20 units down.

What is perimeter?

For geometry, the perimeter of the shape is defined as the total length of the boundary. The perimeter is determined by adding all the sides and side lengths that enclose the shape. It is measured in units such as centimeters, meters, feet and inches,

For the given question:

JK = [tex]\sqrt{(-3-(-3))^{2}+(-9-7)^{2} }[/tex]

JK = [tex]\sqrt{0^{2} +16^{2} }[/tex]

JK = 16

JL = [tex]\sqrt{(-3-x)^{2} +(-9-(-1))^{2} }[/tex]

JL = [tex]\sqrt{(-3-x)^{2} + 8^{2} }[/tex]

JL = [tex]\sqrt{(-3-x)^{2} + 64}[/tex]

KL = [tex]\sqrt{(-3-x)^{2} + (7-(-1))^{2} }[/tex]

KL = [tex]\sqrt{(-3-x)^{2} + 8^{2} }[/tex]

KL = [tex]\sqrt{(-3-x)^{2} + 64}[/tex]

Since, JK + JL+ KL = 36 [Perimeter of triangle]

As we have already calculated, JK = 16

So, 16 + JL+ KL = 36

JL+ KL = 36 - 16

JL+ KL = 20

Since  JKL is an isosceles triangle, JL= KL

So, let's replace KL by JK in the above equation:

JL+ JL = 20

2JL = 20

JL = 10

Now, substitute the value of JL in following equation:

JL = [tex]\sqrt{(-3-x)^{2} + 64}[/tex]

16 =  [tex]\sqrt{(-3-x)^{2} + 64}[/tex]

Now square both sides,

256 = (-3-x)² + 64

256-64 = (-3-x)²

192 = (-3-x)²

13.85 =  -3-x

x = -3 ± 13.85

x = (-3 -  13.85) (-3 + 13.85)

On the prior screen, you sketched `ΔMJN` on the graph with vertices `M(16,-8)`, `J(16,2)`, and `N(4,0)`. What is the area of `ΔMJN`?

Answers

The triangle has an area of 60 square units.

How to determine the area of the triangle based on the location of its vertices

Herein we find the case of a triangle whose vertices are set on a Cartesian plane and whose area can be determined by means of the Heron's formula:

A = √[s · (s - MJ) · (s - JN) · (s - MN)]

s = (MJ + JN + MN) / 2

Where MJ, JN and MN are the side lengths of the triangle and s is the semiperimeter of the triangle.

First, determine the side lengths:

MJ = √[(16 - 16)² + [2 - (- 8)]²]

MJ = 10

JN = √[(4 - 16)² + (0 - 2)²]

JN = √[(- 12)² + (- 2)²]

JN = 2√37

MN = √[(4 - 16)² + [0 - (- 8)]²]

MN = √[(- 12)² + 8²]

MN = 4√13

Second, determine the semiperimeter:

s = (1 / 2) · (10 + 2√37 + 4√13)

s ≈ 18.294

Third, calculate the area of the circle:

A = √[18.294 · (18.294 - 10) · (18.294 - 2√37) · (18.294 - 4√13)]

A ≈ 60.002

The area of the triangle is approximately equal to 60 square units.

Cole scored 18 points in his team's last game. That was 36% of the team's total points for the
game. How many total points did the team score?

Answers

The team's total points for the game was 50.

According to the question,

We have the following information:

Cole scored 18 points in his team's last game. That was 36% of the team's total points for the game.

Now, let's take the score points of the team in the game to be x points.

So, we have the following expression:

36% of x = 18

36x/100 = 18

Multiplying by 100 on both sides of the equation:

36x = 1800

Dividing by 36 on both sides of the equation:

x = 1800/36

x = 50

Write an equation that represents the cost (in dollars) of the posters of the number (in hundreds) of posters ordered (in slope- intercept form).

Answers

The equation that represents the total cost as a function of the number (in hundreds) of posters ordered, x is f(y) = 109.95 + 65x

let

y = total cost

x = numbers in hundreds

cost of first hundred = $109.95

Cost of additional hundred = $65

f(y) = 109.95 + 65x

The total cost of 1000 posters

1000 - first hundred = 900

additional hundreds = 900/100= 9

So,

f(y) = 109.95 + 65x

= 109.95 + 65(9)

= 109.95 + 585

= 694.95

f(y) = $694.95

Therefore, the total cost of 1000 posters is f(y) = $694.95

Mr. Jones' age is 3 years more than 4 times Mahelet's age. If the sum of their ages is 73, how old is Mahelet?

Answers

Mahelet's age is found to be 14 years by solving the simultaneous equations using the given data.

What exactly is a simultaneous equation?

A collection of two or more equations, each having two or more variables, whose values can concurrently fulfil one, more, or all of the equations in the collection, with the number of variables being equal to or fewer than the collection's equations.

Given: Mahelet is four times older than Mr. Jones, who is three years older than Mahelet. The total of their ages is 73.

Let, x =  Mahelet's age

      y =  Mr. Jones's age

We know that,

y = 4x +3

x + y = 73

Solving these equations simultaneously we get,

y = 4(73-y) +3

y = 292 - 4y + 3

5y = 295

y = 59

x = 73 - y = 73 - 59 = 14

The most general form of equation of line in slope intercept form is given by y = mx + c

Where m is the slope of the line and c is the y intercept of the line.

Slope of a line is the tangent of the angle that the line makes with the positive direction of x axis.

If  [tex]\theta[/tex] is the angle that the line makes with the positive direction of x axis, then slope (m) is given by

m =  [tex]tan\theta[/tex]

The distance from the origin to the point where the line cuts the x axis is the x intercept of the line.

The distance from the origin to the point where the line cuts the y axis is the y intercept of the line.

[tex]y - 7 = \frac{7}{4}(x - 2)[/tex]

y = 1.75x - 3.5+7

y = 1.75x  + 3.5

For line g

The line passes through (-3, 4) and (-2, 0)

Slope =

[tex]\frac{0-4}{-2-(-3))}\\-4[/tex]

Equation of line =

y - 4 = -4(x - (-3))

y - 4 = -4x-12\\

y =-4x-12+4\\

y = -4x-8

The first option is correct

which exponential function has an x- intercept?(picture of functions below )

Answers

Question: which exponential function has an x-intercept?

Explanation:

Let the function:

[tex]f(x)=100^{x\text{ -5 }}\text{ - 1}[/tex]

An x-intercept or zero of the function is when y= f(x)=0. In this case, notice that this occurs when x=5, since:

[tex]f(5)=100^{5\text{ -5 }}\text{ - 1= 100}^0\text{ - 1 = 1-1 =0}[/tex]

thus, this function must cross the x-axis at the point x= 5. On the other hand, this function has a horizontal asymptote at y=-1, so the range of this function would be all y > -1. This fact further evidences that this function crosses the x-axis.

Answer: we can conclude that the correct answer is:

[tex]f(x)=100^{x\text{ -5 }}\text{ - 1}[/tex]

Biologists notice an alarming trend in the walleye population in Lake Erie. Despite efforts, the population is decreasing by 15% each year. They estimate the walleye population was 26 million at the beginning of the current year. Write a sequence that lists the population for the first 4 years using 26 million as the first term.

Answers

Given:

The initial population is p = 26 million.

The decreasing percentage is r = 15% each year = 0.15.

The objective is to write the sequence of population after 4 years.

Explanation:

The general formula of population decrease is,

[tex]A=P(1-r)^t\text{ . . . . .(1)}[/tex]

The population in the 1st-year can be calculated by substituting t=1 in equation (1).

[tex]\begin{gathered} A_1=26(1-1.15)^1 \\ =26(0.85) \\ =22.1\text{million} \end{gathered}[/tex]

The population in the 2nd year can be calculated by substituting t=2 in equation (1).

[tex]\begin{gathered} A_2=26(1-0.15)^2 \\ =26(0.85)^2 \\ =18.785million \end{gathered}[/tex]

The population in the 3rd year can be calculated by substituting t=3 in equation (1).

[tex]\begin{gathered} A_3=26(1-0.15)^3 \\ =26(0.85)^3 \\ =15.967255million \end{gathered}[/tex]

Hence, the population for the first 4 years will be,

26million,

22.1million,

18.785million,

15.967255million.
