Step-by-step explanation:
To dilate is to make something bigger. It says in the question that you dilate by a factor of 2, so multiply the length of the side by 2. This will get you 68.
As far as angles are concerned, angles do not change when the object is scaled bigger. So for the angle of A, the answer is still 28 degrees.
This leaves us with our final answer, which is B.

Point A is 4 units away from the origin along the x-axis, and is 7 units away along the y-axis. Which of the following could be the coordinates of Point A?
A. (7, 4)
B. (4, 11)
C. (4, 7)
D. (11, 4)
Answers
Points are labeled as (x,y)
If the unknown point is 4 units away from the origin on the x axis, x will be 4
If the unknown point is 7 units away from the origin on the y axis, y will be 7
Therefore (4,7)
because the x axis is always first of coronates and the y axis is second

15. Consider any eight points such that no three are collinear.
How many lines are determined?
Answers
28
EXPLANATION
there are 8 points of Vishnu three of them are collinear how many lines to the point determine so basically the question mean firstly understand what collinearity mean it means that the points lie in a line so if there are three point if they are collinear it means that they will and makeup one straight line is that no three of them are collinear which means that only two points are collinear not 2.52 be collinear the call through any two points I will it take any two points makes it take this and their straight line is meant to pass through them a straight line always passes through two points at least so we just have to find the total number of the combination of two points which would be taken out from the
combination of eight lines which are there 8.40 so basically we have to find a 32 bit to means the total combination of the two points which are there from the 8.2 it will be 8 factorial upon to factorial in Two States factorial which would give us 56 / to which will be 28586 / to which comes out to be 28 always remember at a point passes through at least two point 1 arbitrarily any two points and a line in is definitely passing through them this is the concept of line and so see which is the option 28 becomes our answer

A bacteria that starts with 3 cells increases by 15% every hour.
Write an exponential growth equation that models the situation
How many bacteria cells will there be in 13 hours?
Answers
Answer:
Step-by-step explanation:
In order to determine the equation, consider that any exponential growth equation can be written as follow:
[tex]f(t)=A(1+r)^t[/tex]
where,
f(t): amount of bacteria after t hours
A: initial amount of bacteria = 3
r: growth rate in decimal form = 0.15 (15%)
t: time in hours
By replacing the previous values into the expression for f(t) you get;
[tex]f(t)=3(1+0.15)^t\\f(t)=3(1.15)^t[/tex]
Hence, the answer is f(t) = 3(1.15)^t
Now, replace t = 13 to determine the amount of bacteria after 13 hours:
[tex]f(13)=3(1.15)^13\\f(13)=18.46[/tex]
Hence, after 13 hours there are approximately 18 bacteria

In the game 'rock, paper, scissors', both players make a fist with one hand. On the count of three, the players make either a rock (by keeping their hand in a fist), a sheet of paper (by holding their hand out flat), or a pair of scissors (by sticking out their first two fingers).
If both players make the same thing, it's a tie. If a rock and scissors are played, the rock wins. If scissors and paper are played, the scissors win. If paper and a rock are played, the paper wins.
a) Play at least 20 games of 'rock, paper, scissors' with a friend. Record the results as you go - write down who won, and what with.
b) After you've finished playing, organise your results into a table and use this to estimate some probabilities. Who was most likely to win? Were either of you more likely to play a certain object each time? Could you use this information to help you win more games next time?

Cindy's house and Jenny's house are 1.33 miles distant from each other.
What is speed?Speed is defined as the rate at which an object is moving (covering a particular distance). It is a scalar quantity as it defines only the magnitude and not direction.
The SI derived unit for speed is meter per second (m/s).
Given,
Cindy leaves house at 9 am and reaches to jenny house at 10 am
Let the distance between Cindy and Jenny house is x
First, Cindy walks half way to jenny house = x/2
then Cindy take U-turn and walks half way to home = x/4
again Cindy take U-turn and reaches jenny house = 3x/4
Total distance walked by Cindy = x/2 + x/4+ 3x/4
= x/2 + x
= 3x/2
Speed of jenny is 2 miles per hour
She walks 3x/2 distance and reaches Jenny house in one hour
⇒ 3x/2 = 2
⇒ 3x = 4
⇒ x = 4/3
⇒ x = 1.33 miles
Hence, distance between Cindy's and jenny's house is 1.33 miles.
