What is a right angles triangle?A right angled triangle is a triangle that has 3 sides and angle with one of its angles to be 90 degrees.
From the given triangle, the measure of the x-coordinate point of G and H will be equal.
Since the line GH intersects the x-axis and the point where the line intersects the x-axis is where y = 0, hence the coordinate H is (a, 0) and the measure of G is (a, +y)
The y-value of G can be any positive value on the y-axis

u=u=
u = - 4w + 9 is the rearranged equation so that w is the independent variable given that the equation is u - 5= - 4(w - 1). This can be obtained by simplifying the equation and taking w to one side of the equation with other constants.
Find the rearranged equation:Simplifying an equation can be done by using the following steps:
Add/subtract the terms from the equation on both sides Multiply/divide the coefficients of the variable in order to isolate the variable Solve for the variable Substitute the variable in the original equation for finding other variables (if any)Here it is given that the equation is,
⇒ u - 5= - 4(w - 1)
We have to find an equation in which w is taken to one side of the equation with other constants.
First by adding both side of the equation with 5 we get,
⇒ u - 5 + 5 = - 4(w - 1) + 5
By opening the bracket we get,
⇒ u = - 4w + 4 + 5
Finally by adding the constants we get,
⇒ u = - 4w + 9
Hence u = - 4w + 9 is the rearranged equation so that w is the independent variable given that the equation is u - 5= - 4(w - 1).

Ray needs help creating the second part of the coaster. Create a unique parabola in the pattern f(x) = ax2 + bx + c. Describe the direction of the parabola and determine the y-intercept and zeros.
The direction of the parabola is determined by the leading coefficient of the polynomial (a > 0 - Upwards, a < 0 - Downwards). The y-intercept of the polynomial is c and the two zeros of the polynomial are x = - b / (2 · a) ± [1 / (2 · a)] · √(b² - 4 · a · c).
What are the characteristics of quadratic equations?
Herein we have a quadratic equation of the form f(x) = a · x² + b · x + c. To determine the direction of the parabola, we must transform this expression into its vertex form and looking for the sign of the vertex constant:
f(x) = a · x² + b · x + c
f(x) = a · [x² + (b / a) · x + (c / a)]
f(x) + b² / (4 · a) - c = a · [x² + (b / a) · x + b² / (4 · a²)]
f(x) + b² / (4 · a) - c = a · [x + b / (2 · a)]²
If a > 0, then the direction of the parabola is upwards, but if a < 0, then the direction of the parabola is downwards.
The y-intercept is found by evaluating the quadratic equation at x = 0:
f(0) = a · 0² + b · 0 + c
f(0) = c
And the zeros are determined by the quadratic formula:
x = - b / (2 · a) ± [1 / (2 · a)] · √(b² - 4 · a · c)
The direction of the parabola is determined by the leading coefficient of the polynomial (a > 0 - Upwards, a < 0 - Downwards). The y-intercept of the polynomial is c and the two zeros of the polynomial are x = - b / (2 · a) ± [1 / (2 · a)] · √(b² - 4 · a · c).

14. Suppose the diameter of circle B were 18 inches instead of 8 inches. What is the
total cost of the glass for your window now?
The total cost of the glass for your window now $174.8
How to determine the total cost of the glass for your window now?The complete question is added as an attachment
From the attached figure, we have the following parameters:
Square of side length 24 inchesCircle B of diameter 20 inchesCircle A of diameter 18 inchesThe area of region 1 is calculated using:
Region 1 = Area of square - Area of circle B
This is calculated as
Region 1 = L^2 - π(d/2)^2
So, we have:
Region 1 = 24^2 - 3.14 * (20/2)^2
Evaluate the quotient
Region 1 = 24^2 - 3.14 * 10^2
Evaluate the exponent
Region 1 = 576 - 3.14 * 100
Evaluate the product
Region 1 = 576 - 314
Evaluate the difference
Region 1 = 262
The cost per square inch of this region is $0.10.
So, we have:
Total cost of region 1 = 262 * $0.10
Total cost of region 1 = $26.10
The area of region 2 is calculated using:
Region 2 = Area of circle B - Area of circle A
This is calculated as
Region 2 = π(D/2)^2 - π(d/2)^2
So, we have:
Region 2 = 3.14 * (20/2)^2 - 3.14 * (18/2)^2
Evaluate the quotient
Region 2 = 3.14 * 10^2 - 3.14 * 9^2
Evaluate the exponent
Region 2 = 3.14 * 100 - 3.14 * 81
Evaluate the product
Region 2 = 314 - 254.34
Evaluate the difference
Region 2 = $59.66
The cost per square inch of this region is $0.15.
So, we have:
Total cost of region 2 = 59.66 * $0.15
Total cost of region 2 = $8.949
The circle B is divided into sectors.
And the angles of the sectors are 90 and 270 degrees
The area of each sector is
Area = ∅/360 * π(d/2)^2
So, we have:
Circle B = ∅/360 * π(d/2)^2 + ⊕/360 * π(d/2)^2
So, we have:
Circle B = 90/360 * 3.14 * (18/2)^2 + 270/360 * 3.14 * (18/2)^2
Evaluate the quotient
Circle B = 0.25 * 3.14 * 9^2 + 0.75 * 3.14 * 9^2
Evaluate the exponent
Circle B = 0.25 * 3.14 * 81 + 0.75 * 3.14 * 81
Evaluate the product
Circle B = 63.585 + 190.755
The cost per square inch of this region is $0.80 for 1 sector and $0.20 for the rest
So, we have:
Total cost of circle B = 63.585 * 0.80 + 190.755 * 0.20
Total cost of circle B = 89.019
Add the total costs
Total cost of the glass for your window = Region 1 + Region 2 + Circle B
Total cost of the glass for your window = $26.10 + $59.66 + $89.019
Evaluate the sum
Total cost of the glass for your window = $174.779
Approximate
Total cost of the glass for your window = $174.8
Hence, the total cost of the glass for your window now $174.8

Part C: What are the steps you would use to graph f(x)? Justify that you can use the answers
obtained in Part A and Part B to draw the graph. (5 points)
(10 points)
Part A
[tex]4x^2 -7x-15=0\\\\(4x+5)(x-3)=0\\\\x=-\frac{5}{4}, 3[/tex]
So, the x-intercepts are [tex]\boxed{\left(-\frac{5}{4}, 0 \right), (3,0)}[/tex]
Part B
The vertex will be a minimum because the coefficient of [tex]x^2[/tex] is positive.
The x-coordinate of the vertex is [tex]x=-\frac{-7}{2(4)}=\frac{7}{8}[/tex]
Substituting this back into the function, we get [tex]f\left(\frac{7}{8} \right)=4\left(\frac{7}{8} \right)^2 -7\left(\frac{7}{8} \right)^2 -15=-\frac{289}{16}[/tex]
So, the coordinates of the vertex are [tex]\boxed{\left(\frac{7}{8}, -\frac{289}{16} \right)}[/tex]
Part C
Plot the vertex and the x-intercepts and draw a parabola that passes through these three points.
The graph is shown in the attached image.

The prices for different lengths of ribbon sold at a fabric store are shown in the table.
Which statement best justifies whether or not the relationship between the length and price represents a function?
the correct option is the last option, the table represents a function because no length of ribbon has more than one price.
What is a function?
A function is a relationship that maps elements from a set, the domain (set of the inputs), into elements from another set, the range (set of the outputs).
Such that each element of the domain can be mapped into only one element of the range.
If we look at the table, we can see that each input (length of ribbon) is mapped into only one output (price). Then we conclude that this table represents a function.
Then the correct option is the last option, the table represents a function because no length of ribbon has more than one price.

Which answer choice has the set of numbers ordered correctly from least to greatest
Its 1.71, 1 3/4, pie, 16/9
Answer: 1.71, 1 3/4, 16/9, pie
Step-by-step explanation: We convert all the numbers to improper fractions. 1.71 = 171/100. 1 3/4 = 175/100 because 3/4 is 0.75. pi is 3.14... which is larger than all of the other numbers. So, pi is the largest. For 16/9, we can just divide to find the solution. Once you divide, you will notice that the answer is 1.77777777... This means that it is larger than 1.71 and 1.75 so 16/9 is the second largest. 1.71 is smaller than 1.75 so the order is 1.71, 1 3/4, pie, 16/9

Answer: Y = 4x + 2
(It would be either the third or fourth choice since they are the same, one of them must be mistaken)
Step-by-step explanation:
Given information
(x₁, y₁) = (1, 6)
(x₂, y₂) = (0, 2)
Find the slope through the formula
[tex]Slope~=~\frac{y_2~-~y_1}{x_2~-~x_1}[/tex]

[tex]\Large Slope~=~\frac{-4}{-1}[/tex]
[tex]\Large Slope~=~4[/tex]
Substitute values into the linear form
Equation: y = mx + b
Point (0, 2)
y = mx + b
(2) = (4) (0) + b
2 = 0 + b
b = 2 - 0
b = 2
Therefore, the equation is [tex]\Large\boxed{y=4x+2}[/tex]
Hope this helps!! :)
Please let me know if you have any questions
Answer:
y = 4x+2
Step-by-step explanation:
The first step is to find the slope
m = ( y2-y1)/(x2-x1)
m = ( 2-6)/(0-1)
= -4/-1
= 4
The slope intercept form of the equation is
y = mx+b where m is the slope and b is the y intercept
y = 4x+b
The y intercept is where x is equal to 0
The y intercept is 2
y = 4x+2
