(02.03 MC) Triangle DOG was rotated to create triangle D'O'G''. Describe the transformation using details and degrees. (10 points) Triangles DOG and D prime, O prime, and G prime are shown. D is at negative 2, 1. O is at negative 3, 3. G is at 1, 1. D prime
Answers
Answer and Step-by-step explanation: Rotation is a "movement" of a geometric figure in order to transform one in another. In rotation, the shape and size of the figure is the same, so they are congruent.
A geometric figure can be rotated clockwise or counterclockwise and by different angles.
One way to recognized the angle of rotation is comparing the points of the figure and its rotated image.
On the figure below, triangle DOG has coordinates:
D (-2,1)
O (-3,3)
G (1,1)
And its image:
D' (2,-1)
O' (3,-3)
G' (-1,-1)
Comparing both set of coordinates, we observe:
D (-2,1) → D' (2,-1)
O (-3,3) → O' (3,-3)
G (1,1) → G' (-1,-1)
that the coordinates for ΔDOG and ΔD'O'G' are opposite to each other, i.e.:
(x, y) → (-x,-y)
rotating counterclockwise.
Since coordinates are opposite and rotation is counterclockwise, ΔD'O'G' is rotated by 180° related to ΔDOG.

The congruence theorem that is used to prove two triangles are:
ASA = angle side angle
SSS = side side side
SAS = side angle side
∠ACB and ∠DCE are vertical angles.
∠B ≅ ∠E
This means that angles B and C are congruent.
BC ≅ EC
This means that sides BC and EC are congruent.
From the given conditions we see that,
∠ACB and ∠DCE are vertical angles
This is an angle condition.
∠B ≅ ∠E
This is an angle condition.
BC ≅ EC

had to pay $172.44 when he returned the truck. For how many miles did he drive the truck?
Answers
Answer: 134 miles
Step-by-step explanation:
f(m) = 16.95 + 0.92m
140.23 = 16.95 + 0.92m
0.92m = 140.23 - 16.95
0.92m = 123.28
m = 123.28/0.92
m = 134 miles

What are the ratio and proportion?The ratio is the division of the two numbers.
For example, a/b, where a will be the numerator and b will be the denominator.
Proportion is the relation of a variable with another. It could be direct or inverse.
Given that,
It took Kim 2 hours 34 minutes to type an 11 page
1 hour = 60 minutes
1 minute = 1/60 hour
34 minutes = 34/60 hour = 0.567 hour
Total hour = 2.567
Now,
Average speed = Number of pages / Number of hour
Average speed = 11/2.567
Average speed = 4.2857 pages per hour.
Hence "The average speed of Kim is 4.2857 pages per hour".

What is proportion?In general, the term "proportion" refers to a part, share, or amount that is compared to a total. According to the concept of proportion, two ratios are in proportion when they are equal.
A mathematical comparison of two numbers is called a proportion. According to proportion, two sets of provided numbers are said to be directly proportional to one another if they increase or decrease in the same ratio. "::" or "=" are symbols used to indicate proportions.
Given:
Number of Tickets Cost
2 $17.00

4 $34.00
5 $42.50
As, y=rx
r= y/x
r= 17/2
r= 8.5
again, r= 34/4
r= 8.5

So the question is how many times do you need to go up/down to get to the next plot on the graph? (Reminder up is positive while down is negative)
So, you go down 5 times which means the top of the slope is -5

Tyson and Ariana each invested $2,500 in separate accounts. Tyson’s interest rate is 5.75% and is compounded annually. Ariana’s simple interest rate is 5.75%. Neither will make any additional deposits or withdrawals. At the end of 6 years, how much more has Tyson earned? Round your answer to the nearest cent.
Answers
Answer:
Tyson's account will have $ 133.90 more than Ariana's account.
Step-by-step explanation:
In Tyson's case, he invests $ 2,500 in an account whose interest rate is 5.75% and is compounded annually. In turn, Ariana invests the same amount and for the same interest, but this is not compounded.
Thus, Ariana, at the end of her 6 years, will have a total amount in her account of $ 3,362.5 (((2,500 x 5.75 / 100) x 6) + 2,500), of which $ 862.5 will correspond to the interest generated.
Instead, Tyson's investment interests will be consolidated annually. Thus, in 6 years, this investment will evolve as follows:
-Year 1 --- 2,500 x 1.0575 = 2,643.75
-Year 2 --- 2,643.75 x 1.0575 = 2,795.76
-Year 3 --- 2,795.76 x 1.0575 = 2,956.52
-Year 4 --- 2,956.52 x 1.0575 = 3,126.52
-Year 5 --- 3,126.52 x 1.0575 = 3,306.29
-Year 6 --- 3,306.29 x 1.0575 = 3,496.40
Thus, at the end of the 6 years, Tyson will have $ 3,496.40 in his account. Thus, Tyson's account will have $ 133.90 more than Ariana's account.
