If BD bisects AC and AC bisects BD, is ABE ≅ CDE? Explain.
A. Yes; the triangles are congruent by AAS.
B. Yes; the triangles are congruent by ASA.
C. Yes; the triangles are congruent by SAS.
D. No; the triangles are not congruent.
Answer:
C. Yes; the triangles are congruent by SAS.
Step-by-step explanation:
From the question, we understand that:
AC and BD bisects one another
The bisection is better illustrated with a diagram. (See attachment).
From this point, I'll use the attachment as a point of reference.
From the attachment:
[tex]AE = CE[/tex] --- Side
and
[tex]BE = DE[/tex] --- Side
When both lines bisect one another, they form a pair of vertical angles [tex]\angle AEB[/tex] and [tex]\angle CED[/tex]
When we apply the theorem of vertical angles to this, we have that:
[tex]\angle AEB[/tex] [tex]=[/tex] [tex]\angle CED[/tex] --- Angle
At this point, we have established:
Two sides of ABE and CDE are congruent
and
One angle in each of ABE and CDE are also congruent
Hence, the triangles are congruent by SAS.

Answer:
Tan(F) = x/y
Step-by-step explanation:
Tan(F) = opposite Side / Adjacent side. The hypotenuse is not involved.
The opposite side is the side that you hit when drawing a line inside F to DE
The Adjacent side is one of the lines forming angle F.
Opposite side = x
Adjacent side = y
Tan(F) = x/y

Which statement describes an advantage to using diagrams or graphs?
A. They make it!possible to do complicated calculations.
B. They can give you a visual sense of unknown quantities.
C. They make difficult problems easy to solve.
Answer:
b
Step-by-step explanation:
One of the advantages of graphs is they can give you a visual sense of unknown quantities.
What is graphical representation?Graphical Representation is a way of analysing numerical data. It exhibits the relation between data, ideas, information and concepts in a diagram. It is easy to understand and it is one of the most important learning strategies. It always depends on the type of information in a particular domain.
Advantages of graphs :-
It allows us to relate and compare data for different time periods. It is used in statistics to determine the mean, mode, and median of different data. It saves a lot of time as it covers most of the information in facts and figures. This in turn compacts the information.
Hence, the advantages can be they can give you a visual sense of unknown quantities.

List the key features of the quadratic equation y = x2 + 6x - 16.
A. x-intercepts: (-8,0) and (2,0), y-intercept: (0,–16), vertex: (-3,-25).
B. X-intercepts: (-8,0) and (2,0), y-intercept: (0,–6), vertex (-3,-25).
C. X-intercepts: (8,0) and (-2,0), y-intercept: (0.-16), vertex: (-3,-25).
D. x-intercepts: (-8,0) and (2,0), y-intercept: (0,16), vertex: (-3,-25).
Answer:
Correct choice is A
Step-by-step explanation:
Quadratic Function
The vertex form of the quadratic function has the following equation:
[tex]y=a(x-h)^2+k[/tex]
Where (h, k) is the vertex of the parabola that results when plotting the function, and a is a coefficient different from zero.
The x-intercepts are the points where the graph of the function crosses the x-axis, they are also called zeros or roots. They can be found by solving the equation y=0,
The y-intercepts are the points where the graph of the function crosses the y-axis. They can be found by setting x=0.
We are given the function:
[tex]y = f(x)=x^2+6x-16[/tex]
Find the y-intercept. x=0:
[tex]f(0)=0^2+6*0-16=-16[/tex]
y-intercept: (0,-16)
Find the x-intercepts, y=0. Solve the equation
[tex]x^2+6x-16=0[/tex]
Factoring:
[tex](x-2)(x+8)=0[/tex]
Which gives x=2, x=-8.
X-intercepts (2,0) (-8,0)
This leaves us only choice A as correct. But we'll compute the vertex also.
Completing squares:
[tex]y=x^2+6x-16=x^2+6x+9-16-9=(x+3)^2-25[/tex]
Comparing with the vertex form of the function, we have: h=-3, k=-25, thus the vertex is located at (-3,-25)
This confirms that the correct choice is A

The hanger image below represents a balanced equation
Answer:
9.1 = a + 4
Step-by-step explanation:
Equations
If the hanger image represents a balanced equation, then the left and the right 'weights' on the hanger must be equal.
On the left side, there is a weight of 9.1, and on the right side, the weight is a+4. Balancing the hanger, we obtain the required equation:
9.1 = a + 4

Need someone who’s really good at math to help me please!! Suppose you buy 3500 worth of furniture for a new house. The furniture store is offering a fixed installment loan with three year financing with no money down at 11.96% annual interest. What is the monthly payment? Round to nearest cent.
Answer:
monthly payment $132.11
Step-by-step explanation:
Interest = Principal x Rate x Time
I = 3500(.1196)(3)
I = 1255.80
Amount = Principal + Interest
A = 3500 + 1255.80
A = 4755.80
Monthly payment = 4755.80 / 36 months = $132.11 monthly
The formula for the volume of a right cylinder is V = (pi)r^2h. Find the rate of change of the volume when r = 2 inches if dr/dt = 1/8 in./min and h = 5r. Show all your work.
Answer:
The volume is increasing at a rate of 15π/2 squared inches per minute.
Step-by-step explanation:
The formula for the volume of a right cylinder is:
[tex]V=\pi r^2h[/tex]
We want to find dV/dt when r = 2, dr/dt = 1/8 in/min, and h = 5r.
Since h = 5r:
[tex]V=\pi(r)^2(5r)=5\pi r^3[/tex]
Differentiate both sides with respect to t:
[tex]\displaystyle \frac{dV}{dt}=15\pi r^2\frac{dr}{dt}[/tex]
Since r = 2 and dr/dt = 1/8:
[tex]\displaystyle \frac{dV}{dt}=15\pi(2)^2\Big(\frac{1}{8}\Big)=\frac{15\pi}{2}[/tex]
So, the volume is increasing at a rate of 15π/2 squared inches per minute.

What is the length of BG and LB need help will mark Brainliest
we get x by setting up a proportion.
[tex]\frac{12}{2x+2}[/tex] = [tex]\frac{21}{5x-1}[/tex]
then we cross multiply.
12(5x−1) = 21(2x+2)
60x − 12 = 42x + 42
18x − 12 = 42
18x = 54
x = 3.
plug in 3 for x for LB, which is 2x + 2.
LB = 2(3) + 2 = 8
plug in 3 for x for BG, which is 5x - 1.
