To find the whole area of an irregular polygon, you must first break it into polygons that are findable. For this figure, we can break it up into two figures, a triangles and a rectangle. To find the triangle, we must first find the height of it. To get that, we take the length of the blue line (the height of the entire figure), and subtract the height of the rectangle (9.6 cm) to get a height of 5.7 cm for the triangle. the area formula for a triangle is 1/2 of the base multiplied by the height. To get the base of the triangle, we add the base of the rectangle to the parts of the triangle that hang past it (6.2 cm in total). 6.2 + 12.8 gives us 19 cm. Now we have (19 x 9.6) divided by 2 to give us 91.2 cm². The area formula for a quadrilateral is just the base (12.8 cm) multiplied by the height (9.6 cm), to give us 122.88 cm². Add the area of the rectangle to the area of the triangle to get our answer, 214 cm².

Part C
How many more boxes of stickers does Mrs. Kim need if she wants each of her students to get
12
12 stickers? Enter the number below.
more boxes of stickers
Answers
Answer:
2
Step-by-step explanation:
first, she would need to get at least 384 stickers in total since 32 (the number of students) x 12 = 384
Each box contains 64 stickers, so 384/64=6
She would need 6 boxes, but the question is asking how many MORE boxes, and she already has 4 boxes so she would need to get 2 more boxes
Divide is the basic multiplication method to distribute the whole of a things into more parts.The total number of stickers Mrs. Kim bought at the store are 256, the number of stickers that each student will get is 8 and the number of boxes of stickers Mrs. Kim need if she wants each of her students to get 12 stickers is 6.
Given-
Total number of boxes are 4.
The number of sticker each box contained is 64.
What is dividing method?Divide is the basic multiplication method to distribute the whole of a things into more parts.
A) Total number of stickers Mrs. Kim bought at the store.
Let Mrs. Kim bought the n number of stickers from the store.
It is given that the each box contained 64 stickers and there are total 4 boxes. Thus the total number of stickers are,
[tex]n=4\times64[/tex]
[tex]n=256[/tex]
Thus the total number of stickers Mrs. Kim bought at the store are 256.
B) The number of stickers that each student will get.
Total number of students in her class is 32.
Total number of sticker is 256.
Let each students will get x number of the sticker. Thus,
[tex]x=\dfrac{256}{32}[/tex]
[tex]x=8[/tex]
Thus the number of stickers that each student will get is 8.
C) The number of boxes of stickers Mrs. Kim need if she wants each of her students to get 12 stickers.
Total number of students in her class is 32.
The number of stickers that each student will get is 12.
Let for 32 students the total number of sticker required is a.Thus,
[tex]a=12\times32[/tex]
[tex]a=384[/tex]
She needs total 384 sticker to distribute 12 stickers to each students. As each box contain 64 stickers. Let b umber of boxes of stickers Mrs. Kim need if she wants each of her students to get 12 stickers.
[tex]b=\dfrac{384}{64}[/tex]
[tex]b=6[/tex]
Thus the number of boxes of stickers Mrs. Kim need if she wants each of her students to get 12 stickers is 6.
Hence the total number of stickers Mrs. Kim bought at the store are 256, the number of stickers that each student will get is 8 and the number of boxes of stickers Mrs. Kim need if she wants each of her students to get 12 stickers is 6.

Gerald is testing a computer graphics program. He needs to insert a parabolic shape by transforming the quadratic parent function, f(x) = x2. Gerald needs the parabolic shape to open downward, stretch vertically by a factor of 2, shift right by 3 units, and shift down by 4 units. Which transformed function should Gerald enter into the computer graphics program to achieve this result?
g(x) = –2(x – 3)2 – 4
g(x) = 2(x – 3)2 – 4
g(x) = –2(x + 3)2 – 4
g(x) = 2(x + 3)2 – 4
Answers
Function, Gerald should enter to the computer is g(x) = -2(x + 3)² - 4
Correct option is C.
What is transformation?Transformations are changes done in the shapes on a coordinate plane by rotation or reflection or translation.
Given,
Parent function f(x) = x²
g(x) = ?
Parabolic shape to be downward, meaning reflection over x- axisfor reflection over x - axis,
g(x) = -f(x)
g(x) = -x²
Stretch vertically by factor 2.For vertical stretch of factor a.
g(x) = a f(x)
g(x) = -2x²
Shift right by 3 unitsFor right shift by a
g(x) = f(x + a)
g(x) = -2(x + 3)²
Shift down by 4 unitsShift down by b units
g(x) = f(x) - b
g(x) = -2(x + 3)² - 4
Hence, g(x) = -2(x + 3)² - 4 is the function, Gerald should enter.

How do you find the equation of each function? Function A is f(x)=3x^2 and Function C is f(x)=18x-16. How do you get those? And then how do you get the equation for Function B? Thanks!
Answers
Answer:
[tex]f(x) = 3^x[/tex] --- Function A
[tex]f(x) = x^2 - 5[/tex] --- Function B
[tex]f(x) = 18x -6[/tex] --- Function C
Step-by-step explanation:
Solving (a): Equation of Function A
An exponential equation is represented as:
[tex]y = ab^x[/tex]
From the graph of function A,
[tex]x = 0\ when\ y = 1[/tex]
[tex]x = 1\ when\ y = 3[/tex]
For: [tex]x = 0\ when\ y = 1[/tex]
[tex]y = ab^x[/tex] becomes
[tex]1 = ab^0[/tex]
[tex]1 = a[/tex]
[tex]a =1[/tex]
For: [tex]x = 1\ when\ y = 3[/tex]
[tex]y = ab^x[/tex] becomes
[tex]3 = a*b^1[/tex]
[tex]3 = a*b[/tex]
Substitute 1 for a
[tex]3 = 1*b[/tex]
[tex]3 = b[/tex]
[tex]b = 3[/tex]
[tex]y = ab^x[/tex] becomes
[tex]y = 1*3^x[/tex]
[tex]y = 3^x[/tex]
Replace y with f(x)
[tex]f(x) = 3^x[/tex]
Solving (b): Equation of Function B
A quadratic equation is represented as:
[tex]y = ax^2 + bx + c[/tex]
From the table of function B,
[tex]x = 3\ when\ y =4[/tex]
[tex]x = 5\ when\ y =20[/tex]
[tex]x = 6\ when\ y =31[/tex]
For: [tex]x = 3\ when\ y =4[/tex]
[tex]y = ax^2 + bx + c[/tex] becomes
[tex]4 = a*3^2 + b*3 + c[/tex]
[tex]4 = a*9 + 3b + c[/tex]
[tex]4 = 9a + 3b + c[/tex]
For [tex]x = 5\ when\ y =20[/tex]
[tex]y = ax^2 + bx + c[/tex] becomes
[tex]20 = a*5^2 + b*5 + c[/tex]
[tex]20 = a*25 + b*5 + c[/tex]
[tex]20 = 25a + 5b + c[/tex]
For [tex]x = 6\ when\ y =31[/tex]
[tex]y = ax^2 + bx + c[/tex] becomes
[tex]31 = a*6^2 + b*6 + c[/tex]
[tex]31 = a*36 + b*6 + c[/tex]
[tex]31 = 36a + 6b + c[/tex]
So, we solve for a, b and c in:
[tex]4 = 9a + 3b + c[/tex]
[tex]20 = 25a + 5b + c[/tex]
[tex]31 = 36a + 6b + c[/tex]
Make c the subject in [tex]4 = 9a + 3b + c[/tex]
[tex]c = 4 - 9a - 3b[/tex]
Substitute [tex]c = 4 - 9a - 3b[/tex] in [tex]20 = 25a + 5b + c[/tex] and [tex]31 = 36a + 6b + c[/tex]
[tex]20 = 25a + 5b + c[/tex] becomes
[tex]20 = 25a + 5b + 4-9a-3b[/tex]
Collect Like Terms
[tex]-4+20 = 25a -9a+ 5b -3b[/tex]
[tex]16 = 16a+ 2b[/tex]
Divide through by 2
[tex]8 = 8a + b[/tex]
[tex]c = 4 - 9a - 3b[/tex]
[tex]31 = 36a + 6b + c[/tex] becomes
[tex]31 = 36a + 6b + 4 - 9a - 3b[/tex]
Collect Like Terms
[tex]-4+31 = 36a - 9a+ 6b - 3b[/tex]
[tex]27 = 27a+ 3b[/tex]
Divide through by 3
[tex]9 = 9a + b[/tex]
Solve for a and b in: [tex]8 = 8a + b[/tex] and [tex]9 = 9a + b[/tex]
Subtract both equations:
[tex]8 - 9 = 8a - 9a + b - b[/tex]
[tex]8 - 9 = 8a - 9a[/tex]
[tex]-1 = -a[/tex]
Divide both sides by -1
[tex]1 = a[/tex]
[tex]a = 1[/tex]
Substitute 1 for a in [tex]9 = 9a + b[/tex]
[tex]9 = 9*1 + b[/tex]
[tex]9 = 9 +b[/tex]
Subtract 9 from both sides
[tex]9-9=9-9+b[/tex]
[tex]0=b[/tex]
[tex]b = 0[/tex]
Substitute [tex]b = 0[/tex] and [tex]a = 1[/tex] in [tex]c = 4 - 9a - 3b[/tex]
[tex]c = 4 - 9*1-3*0[/tex]
[tex]c = 4 - 9-0[/tex]
[tex]c = -5[/tex]
So, the equation is:
[tex]y = ax^2 + bx + c[/tex]
[tex]y=1*x^2 +0*x-5[/tex]
[tex]y=x^2 -5[/tex]
Replace y with f(x)
[tex]f(x) = x^2 - 5[/tex]
Solving (c): Equation of Function C
This is calculated using:
[tex]f(x) =a + (x -1)d[/tex]
Where
[tex]a = 12[/tex] -- the first term
d = the difference between successive terms
[tex]d = 30 -12 = 48-30 = 66 -48[/tex]
[tex]d =18[/tex]
So, we have:
[tex]f(x) =a + (x -1)d[/tex]
[tex]f(x) = 12 + (x - 1)*18[/tex]
Open bracket
[tex]f(x) = 12 + 18x - 18[/tex]
Collect Like Terms
[tex]f(x) = 18x - 18+12[/tex]
[tex]f(x) = 18x -6[/tex]

⇒ 9x
⇒ 9 × 6
⇒ 54
Here, Airport Auto Leasing has a ratio of cars to trucks that is 5 to 3.
Hence, Number of trucks in Airport Auto Leasing is,
⇒ 3x = 24
⇒ x = 8

Answer:
C.7 weeks
Step-by-step explanation:
Subtract 60 on both sides then you get: 30w=210, then divide both sides and you get w=7, so it'll take 7 weeks
Answer:
C. 7 weeks
Step-by-step explanation:
30w + 60 = 270
- 60 -60
subtract 60 from both sides of the equal sign.
30w = 210
We need to isolate the variable, which is (w), so divide both sides by 30.
w = 7
