Given line AB Use similar triangles to prove that the slope AB is the same between any two points on the line.
1. Create two similar, but not equal, right triangles using segments of line AB as the hypotenuse of each triangle. You may choose the given points, A(-5, -1) and B(4,3.5), as two of the points used to create the triangles. For each point used to create the triangles, name the point with a capital letter and coordinates,
2. For the pair of similar triangles created in Part 1, list three pair of corresponding angles that are equal and three sets of proportionate sides.
3. Use the pair of similar triangles created in Part 1 to demonstrate that the slope of line is the same between any two points on the line.
In your final answer, include a copy of your graph labeling original line AB, and all of Parts 1-3. Be sure to show the
vertical and horizontal lengths used for the rise and run of the slope. To submit your answers, use a word processing program or handwritten solutions.

Ace gained $ 176 by selling 32 meters cloth for $1496. Find his loss per meters he sold it for $1276
Answers
Answer:
Selling the total for $ 1276, Ace lost $ 1.37 for each meter.
Step-by-step explanation:
Given that Ace earned $ 176 selling 32 meters of cloth at $ 1496, to find out his loss for each meter if he sold the total for $ 1276, the following calculation must be performed:
1496 - 176 = 1320 (stock price)
1320/32 = 41.25 (price per meter)
1276/32 = 39.87
41.25 - 39.87 = 1.37
Thus, selling the total for $ 1276, Ace lost $ 1.37 for each meter.
Find the missing angles.

A person was modeling a declining population with a decay factor of 0.5 using pennies. They started with 100 pennies and flipped all 100 pennies. Any pennies that landed on tails were removed. Then, the remaining pennies are flipped again and again the ones landing on tails were removed. The process is repeated until no pennies are left. How many flips is the most reasonable expectation for when this model should reach 0 pennies?

Biking at 10 mph, it takes Kristen 1/2 hour to reach the train station to go to work. Kristen then takes the train to work, and it takes another 1/2 hour for her to get to work when the train travels 24 mph. How far does Kristen travel to work?
A.
65 miles
B.
27 miles
C.
17 miles
D.
16 miles
Answers
Answer:
speed = Distance /Time
10 mph = Distance / 0.5 hours
distance = 10 * 0.5
Distance = 5 miles
speed = Distance /Time
24 mph = Distance /0.5 hours
Distance = 24 * 0.5
Distance = 12 miles
Total distance = 5miles + 12miles
= 17miles

Using two or more complete sentences, describe how you can find a vector parallel to B = (-2,3) .
Answers
Answer:
To find a vector parallel to B, such vector must be a scalar multiple of B.
Step-by-step explanation:
Two non-zero vectors are parallel if they are scalar multiples of one another.
A vector parallel to B must be a scalar multiple of B.
let the vector parallel to B be A, then their scalar multiple is given as;
A = kB
A = k(-2, 3)
where;
k is scalar
Thus, to find a vector parallel to B, such vector must be a scalar multiple of B.
