RST is not a right triangle.

<h3>What is a Triangle ?</h3>

A Triangle is a polygon with three sides , three angles and three vertices.

It is given in the question that

triangle RST with coordinates R(2, 3), S(4, 4), and T(5, 0)

It has to be determined that if the triangle is a right angled triangle ,

If we plot the triangle on the coordinate plane , it can be easily seen that the triangle is not a right angled triangle ,

It can also be proved by measuring the length of the sides that if the sum of the squares of the sides is equal to the square of the largest side , then it will be a right triangle or not .

Note: Since you missed to add the image, so after a little research, I was able to find the image related to this question, which hopefully serves the purpose to clear your concept. The image is attached below.

Step-by-step explanation:

Part 1) What is the slope for section "d" of Mrs. Washington's commute

Calculating the slope for section "d" of Mrs. Washington's commute:

Slope of the section d $=\frac{y_{2} - y_{1}}{x_{2} - x_{1}}$

$\frac{6 - 0}{32 - 20}=\frac{1}{2}=0.5$

Part 2) What does it mean that the slope is negative in context of the problem?

The slope is being negative as it is moving downward from the left. In negative slop, the value of x increase, while the vale of y decreases. In positive slop, the value of both x and y increases.

Part 3) Why are the slopes different over different intervals?

Slopes are different at different intervals as the distance covered in time taken for each part of the given journey are different, also the speed is not the same for each interval.

As the speed can be calculated as

$Speed\:=\:\frac{distance}{time}\:$

Distance = $y_{2} -y_{1}$ = $20 - 15 = 5$

Time = $x_{2} -x_{1}$ = $8 - 0 = 8$

Speed = $\frac{5}{8}=0.625$

Therefore, the speed in the part 1 is $0.625$ $ms^{-1}$

Part 4) How long does it take Mrs. Washington to get home? How did you know this?

It is clear from the graph that does take 32 minutes to her to get home.

We can observe it from the graph that it represents the total time taken across the entire journey.

Tyler took 33 photos while on a class field trip this is three times as many photos as Kayla took which equation can be used to

prisoha [69]

33 divided by 3= 11, so Kayla took 11 photos.

Give two points with integer coordinates that have a slope of 10/7 between them

Fittoniya [83]

Answer:

(0,0) and (7,10)

Step-by-step explanation:

recall that the slope - intercept form of a linear equation can be given as

y = mx + b

where m = slope and b = y intercept

in our case, we are given that slope, m = 10/7, hence our equation becomes

y = (10/7) x + b

since we are not given any information about the y-intercept, we can simply pick a value for b that is most convenient for us.

We pick b = 0, hence the equation simplifies to:

y = (10/7) x ----- eq 1

we can see immediately that if x = 0, y must also = 0

proof if x = 0:

y = (10/7)(0) =0

since 0 is an integer, then (0,0) must be the first point.

we can also observe that for y to be an integer, we must get rid of the denominator 7. We can do this by multiply the right side by 7. Hence we let x = 7:

y = (10/7) x 7

y = 10

hence (7,10) is the second point.

Help Please! Thanks so much if u do

Sati [7]

Answer:

$65

Step-by-step explanation:

Let's add up the flat rate and the cost of four tires:

flat rate + 4($122.57/tire) = $555.28

We are to solve for "flat rate." First, multiply out 4($122.57/tire), obtaining a tire cost of $490.28 total. Subtracting this tire cost from the $555.28 Janette paid the shop, we get "flat rate" = $555.28 - $490.28, or $65.

Thus, the installation charge ("flat rate") must have been $65.
