Quadrilateral ABCD rotates 180 degrees around point B,
New quadrilateral formed named LBMN
The corresponding angle after rotation of 180 degrees around B is equals to,
B remain at same position.
A rotates and point L take the position of A.
D rotates and point M take the position of D.
C rotates and point N take the position of C.
Corresponding angle to A is angle L.

ANSWER:
\(\begin{gathered} 4\cdot\frac{1}{2}\cdot(x-2)=(y-1)^2 \\ \text{ Focus }=(\frac{5}{2},1) \\ \text{ Vertex = }(2,1) \\ \text{ Directrix = }\frac{3}{2} \end{gathered}\)STEP-BY-STEP EXPLANATION:
We have the following function:
\(-2x+y^2-2y+5=0\)We convert it to its standard form as follows:
\(\begin{gathered} 2x=y^2-2y+5 \\ x=\frac{y^2}{2}-\frac{2y}{2}+\frac{5}{2} \\ x=\frac{1}{2}\cdot(y-1)^2+2 \\ 2\cdot(x-2)=(y-1)^2 \\ 4\cdot\frac{1}{2}\cdot(x-2)=(y-1)^2 \end{gathered}\)Now, starting from the standard form, we can define the focus, the vertex and the directrix:
\(\begin{gathered} \text{ Focus }=(\frac{5}{2},1) \\ \text{ Vertex = }(2,1) \\ \text{ Directrix = }\frac{3}{2} \end{gathered}\)Work out the length of x. Give your answer rounded to 3 significant figures. 13.3 mm 5.5 mm The diagram is not drawn accurately. X = 0 mm x
Step-by-step explanation:
Based on the information given, we have a diagram with two sides labeled as 13.3 mm and 5.5 mm, and another side labeled as X mm.
To find the length of X, we can use the fact that the sum of the lengths of the sides of a triangle is equal to the perimeter.
Perimeter = 13.3 mm + 5.5 mm + X mm
The perimeter is the total distance around the triangle. Since we have three sides, the perimeter is the sum of the lengths of those sides.
To find X, we can subtract the sum of the known sides from the perimeter:
X mm = Perimeter - (13.3 mm + 5.5 mm)
Since the value of X is not given, we cannot calculate it without the perimeter value. If you provide the perimeter value, I can help you find the length of X.

Let f(x) = -4x + 7 and g(x) = 2x - 6. Find. (gxf)(1)
Answer:
(gxf)(1) = - 12
Step-by-step explanation:
Let f(x) = -4x + 7 and g(x) = 2x - 6.
(gxf)(1) = g(1)xf(1)
but : f(1) = -4(1)+7 =7-4 = 3 and g(1)=2(1)-6 =2-6 = -4
so : (gxf)(1) = g(1)xf(1) = (-4)(3)=-12

Answer:
-14
Explanation:
3 x -3 - 5 = -14
Answer:
-14, -5, 4, and 13
Step-by-step explanation:
For each x value, substitute it for x in the equation.
For the first one where x = -3,
y = 3(-3) - 5
y = -9 - 5
y = -14
So the first one is -14. The next x value is 0
y = 3(0) - 5
y = 0 - 5
y = -5
Second one is -5. The next x value is 3
y = 3(3) - 5
y = 9 - 5
y = 4
Third is 4. The next x value is 6
y = 3(6) - 5
y = 18 - 5
y = 13
So the last one is 13.

find the perimeter of a triangle where one side is 2 inches, one side is 6 inches and another side is 10 inches.
(a) 2in.
(b) 9in.
(c) 36in.
(d) 18in.
Answer:
(d) 18 in.
Step-by-step explanation:
When we're given the three sides of a triangle, one formula we can use for perimeter of a triangle is:
P = s1 + s2 + s3, where
P is the perimeter,and s1, s2, and s3 are the three sides:P = 2 + 6 + 10
P = 8 + 10
P = 18
Thus, the perimeter of the triangle is 18 in.
The table shows a hot air balloon's height h , in feet, during a descent at various times t , in seconds.
Part A: Use the table's first two ordered pairs to find the hot air balloon's rate of change.
Part B: Is the rate of change constant? Explain.
Part C: What was the hot air balloon's height at the time the descent began?
Part D: Write , as a linear function of
.
Using a linear function, we have that:
A. The rate of change is of -12 feet per second.
B. The rate of change is constant.
C. The initial height is of 1210 feet.
D. The linear function is: h(t) = -12t + 1210.
What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.From the table, when x changes by 5 seconds, the height decreases by 60 feet, hence the slope is given by:
m = -60/5 = -12 feet per second.
Hence the function is:
h(t) = -12t + b.
When t = 5, h(t) = 1150, hence we use this to find the initial height.
h(t) = -12t + b.
1150 = -12(5) + b.
b = 1210.
Hence the linear function is:
h(t) = -12t + 1210.

"Our new
training room can seat 150
employees. If 6 tables consisting of 6
chairs are now taken, what
percentage of our new facility's
seating is full?"
Employee: "At this point, we have
used up
of our new seating
capacity."
The percentage of our new facility's seating is full will be 76%.
What is the percentage?The quantity of anything is stated as though it were a fraction of a hundred. A quarter of 100 can be used to express the ratio. Per 100 is what the term percent signifies. The symbol ‘%’ is used to symbolize it.
The percentage is given as,
Percentage (P) = [Initial value - Final value] / Initial value x 100
Our new training room can seat 150 employees.
If 6 tables consisting of 6 chairs are now taken.
Then the number of occupied seats by tables will be
⇒ 6 x 6
⇒ 36
Then the percentage of our new facility's seating is full will be
P = [(150 - 36) / 150] x 100
P = (114/150) x 100
P = 0.76 x 100
P = 76%
The percentage of our new facility's seating is full will be 76%.

Answer:
D: Observational Study
Step-by-step explanation:
edg2020
He did not go around asking people how many of them buy lunch, so it is not a survey. He did not create the settings and conditions or simulate possible examples, so its not B. He did not control or change any variables, so it is not an experiment. He simply walked around and Observed people to get information for his study. Thus it is D.
Mrs. Evans opens a bank account and starts to gain money at a constant rate of $6 per day. What is the total amount of money that she will gain after a week?
Answer:
$42
Step-by-step explanation:
I know this because a week is 7 days and if she is making $6 a day then you would do 7 times $6 which equals $42 so Mrs. Evans will gain a total of $42 after a week.
the diagonals of a rectangle ABCD meet at O if AO=(2x+3)cm and DO=(5x)cm find the length of its diagonals also find the perimeter of the rectangle if AB=8cm.
Step-by-step explanation:
AO = DO
2x+3 = 5x
3 = 5x-2x
3 = 3x
x = 1
DO = 5(1)=5cm
AC = 2×5 = 10cm
BC =√10²-8²
= √100-64
=√36
=6 cm
therefore, the perimeter of the rectangle
= 2×(8+6) = 2(14) = 28 cm

Turn the shape so the trapezoid is on the bottom/base
h=18 for overall shape
B = area of base, trapezoid
B = 1/2 (b₁ + b₂) h
b₁ = 11
b₂ = 25
h = 24 for trapezoid
B = 1/2 (11 + 25)(24)
B = 432
V = Bh
V = (432)(18)
V= 7776 in³
