The figure shows two triangles on a coordinate grid:
A coordinate plane with two triangles is shown. Triangle RST has vertices R at 3 comma 4, S at 1 comma 1, and T at 5 comma 1. Triangle R prime S prime T prime has vertices R prime at 2 comma negative 3, S prime at negative 1 comma negative 1 and T prime at negative 1 comma negative 5.
What set of transformations is performed on triangle RST to form triangle R’S’T’?
A 90-degree counterclockwise rotation about the origin followed by a translation 2 units left
A 270-degree counterclockwise rotation about the origin followed by a translation 2
units to the right
A translation 2 units down followed by a 90-degree counterclockwise rotation about the origin
A translation 2 units down followed by a 270-degree counterclockwise rotation about the origin.
Please answer quickly I am in the middle of a test. (Will Give Brainliest.)
Answer:
D- A translation 2 units down followed by a 270-degree counterclockwise rotation about the origin.
Step-by-step explanation:
I'm sorry that it's late, I still posted it tho so you can give other person branliest.
Hope this helps for other readers :)
Explanation:
If you focus on one point, I'm doing R
if you first translate it down you will go from (3,4) to (3,2)
Then we have R' at (2, -3) which means we need (y, -x)
This can be found with 90 degree clockwise OR 270 degree counterclockwise.

Indicate in standard form the equation of the line passing through the given points.
E(-2, 2), F(5, 1)
Answer:
The equation of the line that passes through the given points is ;
7y = -x + 12
Step-by-step explanation:
Here, we want to get the equation of the line that passes through the given points
The general equation form
is;
y = mx + b
where m is the slope and b is the y-intercept
Now, let us substitute the x and y coordinate values of each of the points;
for (-2,2); we have
2 = -2m + b
b = 2m + 2 •••••(i)
for F;
1 = 5m + b
b = 1-5m ••••••(ii)
Equate both b
1-5m = 2m + 2
1-2 = 2m + 5m
7m = -1
m = -1/7
Recall;
b = 2m + 2
b = 2(-1/7) + 2
b = -2/7 + 2
b = (-2 + 14)/7 = 12/7
The equation of the line is thus;
y = -1/7x + 12/7
Multiply through by 7
7y = -x + 12

4. The 10 seventh graders on the school soccer team.
Step-by-step explanation:
I just submitted the form and these are the right answers :)
It might be not on time but still lol.
I AM SURE THOSE ARE RIGHT ANSWERS !!! :)))
The 20 students in a seventh grade math class, the seventh grade students participating in a science fair put on by the four middle schools in a school district and the 10 seventh graders on the school soccer team are the samples.
What is Statistics?Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.
The samples that are a part of the population of interest, which is seventh grade students at your school, are:
The 20 students in a seventh grade math class.
The seventh grade students participating in a science fair put on by the four middle schools in a school district (if the students are from your school).
The 10 seventh graders on the school soccer team (if they are from your school).
The samples that are not a part of the population of interest are:
The first 20 students to arrive at school on a particular day (as this may include students from different grades or schools).
The students on the school debate team (as this may include students from different grades or schools).
Hence, the 20 students in a seventh grade math class, the seventh grade students participating in a science fair put on by the four middle schools in a school district and the 10 seventh graders on the school soccer team are the samples

Approximately how long does it take a sample of francium-223 to decay by 50%?
A. 80 minutes
B. 100 minutes
C. 20 minutes
D. 40 minutes
By reading off the graph as shown in the question, we can see that the time that is required is 20 minutes.
What is the half life?The half life is the time that it taken for only half or 50% of the isotopes that were originally present in the sample to remain. We know that the half life does differ by the kind of sample that is used.
In this case, we want to determine how long does it take a sample of francium-223 to decay by 50%. This could easily be done from the graph of the decay as shown in the question.

A line that includes the points (-2, c) and (-1, 10) has a slope of 2. What is
the value of c?
Answer:
8
Step-by-step explanation:
m = (Y2-Y1) ÷ (X2- X1) 2 = (10-c) ÷ (-1-(-2)) 2 = (10-c) ÷( 1)2= 10-cc = 10-2c= 8(-2,c) and (-1,10)
10-c
-1--2
10-c
1
We need the fraction to be 2, or 2/1. The bottom number is 1, so we technically already have the answer. But we still need to plug in a number for c. To get 2, we need to subtract 8 from 10.
So c is 8.

Answer:
y=7, x=7
Step-by-step explanation:
They both equal y, so you can set the right part of the equations equal to each other
4x-21=2x-7
solve for x
2x-21=-7
2x=14
x=7
knowing x, we can now substitute back into one of the original equations to find y
y=4(7)-21=28-21=7
or
y=2(7)-7=14-7=7

The population standard deviation for the heights of dogs, in inches, in a city is 3.4 inches. If we want to be 90% confident that the sample mean is within 1 inch of the true population mean, what is the minimum sample size that can be taken?
Answer:
The minimize size that can be taken is - 31.28 or 31 .
Step-by-step explanation:
Lets calculate -
Population standard deviation, [tex]\sigma=3.4 inches[/tex]
Margin of error, E = 1
Critical value , [tex]z_0_._0_5 =1.645[/tex]
Now , the size of the sample , [tex]n=(\frac{z\times \sigma}{E} )^2[/tex]
Putting the given values ,
[tex]=(\frac{1.645\times 3.4}{1})^2[/tex]
= 31.28 or 31 .
The given table of the question has been attached here .
Hence , the answer is 31.

What happens to light when it strikes a smooth shiny surface?
Step-by-step explanation:
Light reflects from a smooth surface at the same angle as it hits the surface. For a smooth surface, reflected light rays travel in the same direction. This is called specular reflection. For a rough surface, reflected light rays scatter in all directions.Answer:
When light strikes an object, its rays can be either absorbed or reflected. A solid black object absorbs almost all light, while a shiny smooth surface, such as a mirror, reflects almost all light back. When reflected off a flat mirror, light bounces off at an angle equal to the angle it struck the object.

Shanna deposit 11,500 and leaves the funds in her account for 14 years how much will she have if the interest rate of the bank offered 4.9%
Hello!
This is a problem about interest rates.
Since we are not given the "[tex]n[/tex]" value, how many times this interest applies per time period, we can assume that we are most likely dealing with simple interest with an annual interest rate.
The simple interest formula is as follows,
[tex]A=P(1+rt)[/tex]
Where [tex]A[/tex] is the total amount, [tex]P[/tex] is the initial principal balance, [tex]r[/tex] is the annual interest rate, and [tex]t[/tex] is time in years.
Since we are given all this information, we can just solve after converting the interest rate of 4.9% to a decimal, which is 0.049.
[tex]A=11500(1+0.049*14)[/tex]
[tex]A=11500(1.686)[/tex]
[tex]A=19389[/tex]
So at the end of the 14th year, Shanna will have $19,389 in her account.
Hope this helps!
