Answer 1

Answer:

The triangles are similar (proof of that is a different question), so the ratio of horizontal side to long side is the same for each.

$(5200\,ft)/(5600\,ft)=\frac{\text{??}}{7000\,ft+5600\,ft}\n\n(12600\,ft)\cdot(52)/(56)=\text{??}=11700\,ft$

The distance from A to E is 11,700 feet.

Answer 2

Answer:

First prove that triangles ABD and ACE are similar (AA).

Then using corresponding sides of similar triangles are proportional, we can form the proportionality equation

AE/AC = AD/AB

=> AE/(7000+5600) = 5200/5600

Cross multiply,

AE=5200/5600*(12600)

=11700 feet

Point A is located at (0, -2) and is rotated 180°. What are the coordinates of point A'?(2, 0)

Answers

(0,2)

Here are a few tricks:
rotated 180 degrees= (X,Y) ----- (-X, -Y)
rotated 90 degrees= (X,Y) ------(-Y,X)
rotated 270 degrees= (X,Y)-----(Y,-X)

the arrival rate is 9 / hour and the service rate is 14 / hour. the arrival and service distributions are not known so we can't use the m/m/1 formulas. if the average waiting time in the line is 24 minutes, then what is the length of the line?

Answers

The length of the line is approximately 5 people.

To find the length of the line given the arrival rate, service rate, and average waiting time, you can use the following formula:

Length of the line = (Arrival rate × Average waiting time) + (Arrival rate / Service rate)

First, convert the average waiting time from minutes to hours:

24 minutes = 24/60 = 0.4 hours

Now, plug in the given values into the formula:

Length of the line = (9 arrivals/hour × 0.4 hours) + (9 arrivals/hour / 14 services/hour)

Length of the line = (3.6 arrivals) + (0.6429 arrivals)

Length of the line ≈ 4.24 arrivals

Since you can't have a fraction of a person in the line, round up to the nearest whole number:

Length of the line ≈ 5 arrivals

So, the length of the line is approximately 5 people.
