First we need to calculate lenght of each side of triangle.
we use formula for finding distance between 2 points in xy coordinate system.
AB = √13
BC = √13
AC = √26
In order for triangle to be equilateral it must have all 3 sides equal lenght which in this case isn't correct. In order for it to be right it has to suit pythagoras theorem.
AC^2 = AB^2 + BC^2
expressing values of AC, AB and BC we can see that condition for right triangle is fulfilled.
Answer is RIGHT.
Please give you books and lemme study for you, so I can take do your homework and take all your tests, and at the end you will graduate without put anything in you brain cells. I hope this is helpful hopefully you learn something. And please give 5 stars rating and if you want to brake it down step by step please don’t hesitate to ask me.
Answer:
Step-by-step explanation:
The domain of this function is "all real numbers," provided that the graph continues downward, and in this case the range is (-∞, 1].
If, however, the graph is cut off at the line y =1, then the domain is [-3, 3] and the range is [-8, 1].
If they are equivalent that means they’re the same length and so BM is half the total length. Half of 36 is 18
Answer:
Step-by-step explanation:
Hello!
Using the variables:
Y: Sales of all branches of a major international corporation.
X: Advertising of all branches of a major international corporation.
The following regression model was estimated:
^Y= 5000 + 7.25Xi
You have to predict a certain value of Y given a value of X:
^Y/X=$ 30000
To do so all you have to do is replace the value in the formula of the regression line:
^Y= 5000 + 7.25*30000
^Y= $ 222500
With a budget difference of $30000 for advertising, the estimated sales difference is $2225000.
I hope it helps!
