Answer:
x = 8.5
Step-by-step explanation:
You have all three angles already, so it's easy: 90°, (4x - 8)°, (6x + 13)°
The sum of all angles is 180°
90 + (4x - 8) + (6x + 13) = 180
10x + 95 = 180
- 95 -95
10x = 85
x = 8.5

Describe two different ways you could find measure of CFD. What is the measure of
this angle?
Answer:
∠CFD = 60°
Step-by-step explanation:
Along line CE:
∠AFE + ∠AFB + ∠BFC = 180° (sum of angles on a straight line)
(7x + 4) + (8x + 6) + (6x + 2) = 180
collecting alike terms:
7x + 8x + 6x + 4 + 6 + 2 = 180
21x + 12 = 180
21x = 168
x = 8°
We could find the measure of CFD using:
a) Along line AD:
∠AFB + ∠BFC + ∠CFD = 180° (sum of angles on a straight line).
(8x + 6) + (6x + 2) + ∠CFD = 180
14x + 8 + ∠CFD = 180
∠CFD = `180 - (14x + 8)
∠CFD = 172 - 14x
b) ∠CFD = ∠AFE (vertical opposite angles are equal)
∠CFD = 7x + 4
To find value of ∠CFD, substitute x = 8
∠CFD = 7(8) + 4
∠CFD = 60°
Owen is planning surgery to repair the torn ligament in his knee. The total cost of the surgery is expected to be about $7,000. Owen has a $1,000 deductible and then a 20 per- cent co-pay for this procedure. How much will Owen pay for his part of the surgery?
Answer:
$2200
Step-by-step explanation:
Given that Owen has $7000 to pay, with a $1000 deductible. This means that he has, left to pay, $6000.
Again, we're told that he has 20% Co pay for the procedure. Taking 20% of $6000, we have
20/100 * 6000 = $1200. This means be has $1200 to co pay for the procedure.
Adding this newly calculated $1200 with the previously set aside $1000, we have a total of $2200. This is the price Owen will pay from his part, as part of the surgery

Write a function to represent each series of transformations:
• rotation of 90 degrees counterclockwise about the origin, point O, then a reflection across the x-axis
• reflection across the y-axis, then a translation a units to the right and b units up
• translation a units to the right and b units up, then a rotation of 180 degrees counterclockwise about the origin, then a reflection across the y-axis
Answer:
Step-by-step explanation:
For the first one, I believe you would need to use a rotation matrix; to rotate 90º counterclockwise, the matrices would look like ; you would then multiply those out. A reflection across the x-axis would be changing the sign of f(x) (from negative to positive or positive to negative), a reflection across the y-axis would be changing the sign of x, translation a units to the right would be subtracting a from x, translation b units up would be adding b to x. Rotation of 180º about the origin would be the same format as the first matrix, except it would be cos180 and cos0 on the top and sin180 sin0 on the bottom. Reflection across the y-axis would be changing the sign of x again.
OR
1. We know that, 'Translation shifts the figure in any direction'.
As, the function f(x) is translated 'a' units to the right, the new form of function is f(x-a).
Again, the function is translated 'b' units up, the final form of the function is f(x-a)+b.
2 and 3. We know that, ' Reflection flips the image over a line'.
As the function g(x) is reflected over y-axis, the new form of the function is g(-x).
As the function h(x) is reflected over x-axis, the new form of the function is -h(x).
4 , 5 and 6. We know that, 'Rotation turns the image around a point to a certain degree'.
Let us assume the function to be a point (x,y).
As the function is rotated by 90° counterclockwise about the origin, the new function becomes ( y,-x ) i.e. R_{90}R
90
(x,y) = ( -y,x ).
As the function is rotated by 180° counterclockwise about the origin, the new function becomes ( y,-x ) i.e. R_{180}R
180
(x,y) = ( -x,-y ).
As the function is rotated by 2700° counterclockwise about the origin, the new function becomes ( y,-x ) i.e. R_{270}R
270

The scale drawing of a porch is 8 inches wide by 12 inches long. If the actual porch is 12 feet wide, find the length of the porch. (Draw and label polygons then solve.)
Answer: The length of porch is 18 feet.
Step-by-step explanation:
Given: The scale drawing of a porch is 8 inches wide by 12 inches long.
The actual porch is 12 feet wide.
Actual porch and the drawing are similar, then
[tex]\dfrac{\text{Actual length}}{\text{Actual width}}=\dfrac{\text{ length in drawing}}{\text{Width in drawing}}[/tex]
[tex]\Rightarrow\ \dfrac{\text{Actual length}}{12}=\dfrac{12}{8}\\\\\Rightarrow\ \text{Actual length}= \dfrac{12}{8}\times12\\\\\Rightarrow\ \text{Actual length}= 18[/tex]
Hence, the length of porch is 18 feet.
Given that the corresponding sides of similar shapes are proportional, the length of the porch would be calculated as: 18 inches.
What are Similar Shapes?Shapes that are similar have corresponding sides that are proportional to each other.
Thus:
Length of scale drawing = 12 inchesActual length of porch = xWidth of scale drawing = 8 inchesActual width of porch = 12 ftTherefore:
x/12 = 12/8
Cross multiply
8x = (12)(12)
x = 18 inches.
Therefore, given that the corresponding sides of similar shapes are proportional, the length of the porch would be calculated as: 18 inches.

Answer:
w= - 5/3 + 1/120y, y eR
Step-by-step explanation:
y=120w + 200
Move the terms
-120w=200-y
Divide both sides
w= - 5/3 + 1/120y
Write in parametric form
w= - 5/3 + 1/120y, y eR
Find the gradient of each of these functions at the point indicated.
a) y = x^2 at (3,9)
b) y = - 4x^3 at (1,-4)
c) y = 2x^4 at (-1,2)
d) y = 6x at (2, 12)
Answer:
Remember that the gradient is equivalent o the derivative evaluated in one point.
And remember that if we have a function like:
f(x) a*x^n
The derivative is:
f'(x) = n*a*x^(n - 1)
Then knowing this, let's start:
a) y = x^2
the derivative is:
y' = 2*x
And we want to evaluate this in the point (3, 9), then we just need to replace x by 3.
y'(3) = 2*3 = 6
The gradient of y = x^2 at (3, 9) is 6.
b) y = -4*x^3
The derivative is:
y' = 3*(-4*x^2) = -12*x^2
And we want to evaluate this on (1, -4), then we need to replace x by 1.
y'(1) = -12*1^2 = -12
The gradient of y = -4*x^3 at (1, -4) is -12.
c) y = 2*x^4
The derivative is:
y' = 4*2*(x^3) = 8*x^3
And we want to evaluate this on (-1, 2), then we need to replace x by -1.
y'(-1) = 8*(-1)^3 = -8
The gradient of y = 2*x^4 at the point (-1, 2) is -8
d) y = 6*x
The derivative is:
y' = 6
We can see that here we do not have any dependence on x, so the gradient will be the same for all values of x, this means that the gradient at the point (2, 12) is 6.
If P is the incenter of triangle JKL, find the measure of JKP.
Answer:
m∠JKP = 31.5°
Step-by-step explanation:
Incenter of a triangle is the point where all the bisectors of interior angles intersect each other.
JN is the angle bisector of ∠KJL.
Therefore, m∠KJN = m∠LJN
(7x - 6) = (5x + 4)
7x - 5x = 6 + 4
2x = 10
x = 5
m∠KJN = (7x - 6)
= 7(5) - 6
= 35 - 6
= 29°
In ΔKJN,
m∠JKN + m∠KNJ + m∠NJK = 180°
m∠JKN + 90° + 29° = 180°
m∠JKN = 180°- 119° = 61°
Since KO is the angle bisector of ∠JKN,
m∠JKP = [tex]\frac{1}{2}(\angle JKN)[/tex]
= [tex]\frac{1}{2}(61)[/tex]
= 30.5°

-2x + 6y = 6
y = 2x + 11
Answer:
(x, y) = (-6, -1)
Step-by-step explanation:
-2x + 6y = 6
y = 2x+11
By substituting the value of y (second equation) into the first equation, we get
-2x + 6(2x+11) = 6
-2x+12x+66 = 6
10x = -60
x = -6
So, y = -1
