CD is the perpendicular bisector AB. G is the midpoint of AB. points E and F lie on CD. which pair of line segments must be cong
ruent?
2 answers:
Answer:
AE and BE
Step-by-step explanation:
Please refer to the image attached with this.
Here in we have made a diagram a per the conditions given in the question. If we observe ΔABE, We see
AG=GE ( CD is perpendicular bisector of AB , Hence G is mid point)
∠AGE = ∠BGE = 90°
GE = GE
Hence
ΔAGE ≅ ΔBGE
Therefore the theorem of congruent triangles ,
AE ≅ BE

Answer:
Step-by-step explanation:
We know that:
Where "d" is distance, "r" is rate and "t" is time.
Solved for the time "t":
The first step is to convert the distance from miles to feet.
Since , we get:
Knowing that:
We can substitute values into in order to find the time in seconds:
Since:
The time in minutes is:
The question is incomplete. The complete question is :
Davison Electronics manufactures two LCD television monitors, identified as model A and model B. Each model has its lowest possible production cost when produced on Davison’s new production line. However, the new production line does not have the capacity to handle the total production of both models. As a result, at least some of the production must be routed to a higher-cost, old production line. The following table shows the minimum production requirements for next month, the production line capacities in units per month, and the production cost per unit for each production line:
Production per unit Minimum production
Model New Line Old Line requirements
A $30 $50 50,000
B $25 $40 70,000
Production 80000 60000
line capacity.
Let
AN- Units of model A produced on the new production line
AO Units of model A produced on the old production line
BN Units of model B produced on the new production line
BO Units of model B produced on the old production line
Davison's objective is to determine the minimum cost production plan. The computer solution is shown in Figure 3.21.
a. Formulate the linear programming model for this problem using the following four constraints:
Constraint 1: Minimum production for model A
Constraint 2: Minimum production for model B
Constraint 3: Capacity of the new production line
Constraint 4: Capacity of the old production line
Solution :
<u>Linear programming model</u>:
Linear programming is defined as a mathematical model where the linear function is either minimize or maximize when they are subjected to some constraints.
The linear programming model is determined as follows :
Minimum : 30 AN + 50 AO + 25 BN + 40 BO
This is subject to the constraints as :
