Answer:
[tex]4x² + 2y² + x²y² + 8 \\arranging \: them \\ 4 {x}^{2} + {x}^{2} {y}^{2} + 2 {y}^{2} + 8 \\ {x}^{2} (4 + {y}^{2} ) + 2(y^{2} + 4) \\ ({x}^{2} + 2)(y^{2} + 4)[/tex]
Answer:
(4 + y^2) ( x^2 + 2)
Step-by-step explanation:
irst rearrange the terms
4x^2 + x^2 y^2 + 2y^2 + 8
then factorise
x2 ( 4 + y^2) + 2 ( y^2 + 4)
group like terms together and insert the remaining terms into a bracket

Graph g(x)=5|x -6|+2g(x)=5∣x−6∣+2g, left parenthesis, x, right parenthesis, equals, 5, vertical bar, x, minus, 6, vertical bar, plus, 2.
The graph of the absolute value function can be seen at the end of the answer. There we see a translated and dilated parent function.
How to graph the absolute value function?Here we want to graph:
g(x) = 5*|x - 6| + 2
First, remember that the minimum of the absolute value part |f(x)| is 0, so the minimum of the above function is 2, and that happens when x = 6. That will be the vertex of our function.
From that point, we will have two lines, one that goes to the right with a slope of 5, and the other that goes to the left with slope of -5 (the coefficient that multiplies the absolute value part of the function).
The graph of the function can be seen below.

Sam is paying off his eight-year, $15,360 loan in semiannual installments. the loan has an interest rate of 9.58%, compounded semiannually, and a service charge of $1,294.64. once the loan has been fully paid off, what percentage of the total finance charge will the service charge be? round all dollar values to the nearest cent. a. 5.48% b. 8.43% c. 18.55% d. 15.65% please select the best answer from the choices provided a b c d
The percentage of the total finance charge will the service charge is 15.65%. Then the correct option is D.
What is the percentage?The amount of something is expressed as if it is a part of the total which is a hundred. The ratio can be expressed as a fraction of 100. The word percent means per 100. It is represented by the symbol ‘%’.
Sam is paying off his eight-year, $15,360 loan in semiannual installments.
The loan has an interest rate of 9.58%, compounded semiannually, and a service charge of $1,294.64. Once the loan has been fully paid off.
A = $15360
r = 0.0958/2 = 0.0479
n = 8 × 2 = 16
The periodic payment is given as
[tex]\rm A = P (\dfrac{1-(1+r)^{-n}}{r})[/tex]
Where P is Periodic payment
r = rate per period
n = number of period
Then we have
[tex]\rm 15360 = P(\dfrac{1-(1+0.0479)^{-16}}{0.0479})\\\\\\ P = 1396.16[/tex]
Then Sam will pay a total of 1396.16 × 16 = $22,338.56
Interest charge = 22338.56 – 15360 = $6978.56
Total finance charge = 6978.56 + 1294.64 = $8273.20
Then the percentage of the total finance charge will the service charge will be
[tex]\rm Percentage = \dfrac{1294.64}{8273.20}*100\\\\Percentage = 15.65 \%[/tex]

Find the missing variables
Answer:
x = y = 102.5°
Step-by-step explanation:
x and y are congruent.
the sum of the 4 angles in a kite = 360°
subtract the 2 given angles from 360°
360° - 95° - 60° = 360° - 155° = 205° , then
x = y = 205° ÷ 2 = 102.5°

An engineer is tasked with doubling the length and width of a city park. The engineer draws the park on a coordinate plane and labels it ABCD. Find the area of the park before and after the expansion. A coordinate plane with Square A B C D plotted. Point A is at zero comma three. Point B is at thee comma three. Point C is at three comma zero, Point D is at zero comma zero. A photo of a park with a caption that says, dimensions of park are being doubled. What is the area of the park before the expansion?
The vertex coordinates of the park the engineer draws, A(0, 3), B(3, 3),
C(3, 0), D(0, 0) give the area of the park before expansion as 9 unit².
How can the area of the park be found?
The shape of the park = A square
The vertices of the park = ABCD
The coordinates of the point are; A(0, 3), B(3, 3), C(3, 0), D(0, 0)
The length of side AB = 3 - 0 = 3
Length of side BC = 3 - 0 = 3
Length of side CD = 3 - 0 = 3
Length of side AD = 3 - 0 = 3
Therefore, the park is a square with side length, s = 3 units
The area of a square, A = Side × Side = s²
The area of the park before expansion, A = 3 unit × 3 unit = 9 unit²

Answer:
m = 5
Step-by-step explanation:
[tex] \frac{10}{m - 5} = \frac{8}{m - 5} \\ \\ 10(m - 5) = 8(m - 5) \\ \\ 10m - 50 = 8m - 40 \\ \\ 10m - 8m = 50 - 40 \\ \\ 2m = 10 \\ \\ m = \frac{10}{2} \\ \\ m = 5[/tex]
Answer:
m = 5
Step-by-step explanation:
Cross product to get: 10(m-5) = 8(m-5)
Solve for m:
10m-50 = 8m-40
10m - 8m = -40 + 50
2m = 10
m = 10/2
m = 5
find the length of the diameter of circle 0
Answer:
Diameter = 19.33
Step-by-step explanation:
Imaging a radius line from O to the endpoints of the 7. call this line R.
Label the part of the vertical line from O to the 90 degree intersection y.
Now you have a right triangle.
Using the Pythagorean theorem:
R² = 7² + y²
also
y = R - 3
substitute for y:
R² = 49 + (R-3)²
R² = 49 + R² - 6R + 9
simplify:
0 = 58 - 6R
6R = 58
R = 9.6667
Diameter = 2(9.6667) = 19.33
find the area of this figure. round your answer to the nearest hundredth. use 3.14 to approximate pi
Answer:
51.63 m²
Step-by-step explanation:
[tex]\textsf{Area of a semicircle} =\dfrac12\pi r^2[/tex]
Given:
[tex]\pi =3.14[/tex][tex]\textsf{diameter}=6 \textsf{ m}\implies \textsf{radius}=3 \textsf{ m}[/tex][tex]\implies \textsf{area}=\dfrac12 \times 3.14 \times 3^2=14.13[/tex]
[tex]\textsf{Area of a triangle} =\dfrac12 \times \textsf{base} \times \textsf{height}[/tex]
Given:
base = 3 mheight = 5 m[tex]\implies \textsf{area}=\dfrac12 \times 3 \times 5=7.5[/tex]
[tex]\textsf{Area of a rectangle} =\textsf{width} \times \textsf{length}[/tex]
Given:
width = 5 mlength = 6 m[tex]\implies \textsf{area}=5 \times 6=30[/tex]
Total area = area of semicircle + area of triangle + area of rectangle
= 14.13 + 7.5 + 30
= 51.63 m²
Solution:
Step-1: Find the area of the triangle.
[tex]\text{Area of triangle} = \dfrac{1}{2} \times \text{Base} \times \text{Height}[/tex]
[tex]\text{Area of triangle} = \dfrac{1}{2} \times 3 \times 5[/tex]
[tex]\text{Area of triangle} = 3 \times 2.5[/tex]
[tex]\text{Area of triangle} = 7.5 \ \text{m}^{2}[/tex]
Step-2: Find the area of the rectangle.
[tex]\text{Area of rectangle} = \text{LB}[/tex]
[tex]\text{Area of rectangle} = (6)(5)[/tex]
[tex]\text{Area of rectangle} = 30 \ \text{m}^{2}[/tex]
Step-3: Find the radius of the semi-circle.
[tex]\text{Diameter = 2(Radius)}[/tex]
[tex]6 \ \text{m = 2(Radius)}[/tex]
[tex]\dfrac{6}{2} \ \text{m} = \dfrac{2\text{(Radius)}}{2}[/tex]
[tex]3 \ \text{m} = \text{Radius}[/tex]
Step-4: Find the area of the semi-circle.
[tex]\text{Area of semi-circle} = \dfrac{\pi r^{2} }{2}[/tex]
[tex]\text{Area of semi-circle} = \dfrac{(3.14)( 3^{2} )}{2}[/tex]
[tex]\text{Area of semi-circle} = \dfrac{(3.14)(9 )}{2}[/tex]
[tex]\text{Area of semi-circle} = (3.14)(4.5 )[/tex]
[tex]\text{Area of semi-circle} = 14.13 \ \text{m}^{2}[/tex]
Step-5: Find the area of the figure.
[tex]\text{Area of figure = Area of triangle + Area of rectangle + Area of semicircle}[/tex]
[tex]\text{Area of figure = 7.5 + 30 + 14.13}[/tex]
[tex]\boxed{\text{Area of figure = 51.63 m}^{2}}[/tex]

How do the slopes and y–intercepts of the two equations compare?.
The two equations with slope and y-intercept are compared as the lines may be intersecting, parallel, and coincident.
What is the linear system?A Linear system is a system in which the degree of the variable in the equation is one. It may contain one, two, or more than two variables.
Let the two equations in the form of slope and y-intercept.
[tex]\rm L_1: y = m_1x +c_1\\\\L_2: y = m_2x +c_2[/tex]
There are three cases are as follows;
Case 1 - If lines are intersecting then the slope of both equations will be different.
Case 2 - If lines are parallel then the slope of lines are same but the intercept will be different.
Case 3 - If lines are coincident their slope and the intercept will be the same.
