There are many steps to find the coordinates of the vertices of triangle ABC.
The slope formula is y2 - y1 / x2 - x1
There would be three equation associated with this problem.
The first equation can be found by taking the x and y's from A and B
First Equation: 2 - 3 / 1 - (-1)
Answer: -.5
The second equation can be found by taking the x and y's from B and C
Second Equation: -1 - 2 / -3 - 1
Answer: 12
The third equation can be found by taking the x and y's from C and A
Third Equation: 3 - (-1) / -1 - (-3)
Answer: 2
These are not equal measurements so, it isn't right angle.
Answer:
We know it's at -1260 feet and descends 5 per minute
The expression of this would be: -1260 - 5x, where x would be the time in minutes, as from -1260 feets it descends 5 per min.
Then, if we need to calculate it when it passes 12 minutes, we can replace the x by 12, and get the distance it would be
-1260 -5*12 = -1320 feet
And the answer would be -1320 feets
Since we are given that y is directly proportional to x and that when y = 11, x equals 6, we can set up a proportion. Before doing that however, we need to note that the question is asking for the value of y when x = 9. Here is the equation:
Now, just cross multiply and solve for y to get a value of 16.5. Therefore, the value of y when x = 9 is
16.5. Hope this helped and have a phenomenal day!

That's because bananas and pears are two different fruits
Answer:
The maximal margin of error associated with a 95% confidence interval for the true population mean is 2.238.
Step-by-step explanation:
We have given,
The sample size n=42
The sample mean
The population standard deviation
Let be the level of significance = 0.05
Using the z-distribution table,
The critical value at 5% level of significance and two tailed z-distribution is
The value of margin of error is
The maximal margin of error associated with a 95% confidence interval for the true population mean is 2.238.
