Step-by-step explanation:</h2>
A function
from a set
to a set
is a relation that assigns to each element
in the set
exactly one element
in the set
. The set
is the domain (also called the set of inputs) of the function. From the figure, we can see that this set is the x-coordinate of each red point. So this set is {-6, -2, 5}
Hi!to calculate a square root without a calculator is to see if you can get to that whole number by squaring smaller numbers,or multiplying a smaller number by it self.
Exact form
-3/2
Decimal form
-1.5
Mixed number form
-1 1/2
Answer:
- sides: isosceles
- angles: right
Step-by-step explanation:
At first, lets find the distance from one point to the other.

The same way, you can find that:

Since the triangle has only its two sides equal to each other (AB = AC),
it's an isosceles one.
As long as the angles are concerned, we gotta "cheat". In other words, we see that:

By the inverse of pythagorean theorem, we know that if the above equation holds, then we have a right-angled triangle. That is to say that,
A = 90
Since its an isosceles triangle, AB = AC,
B = C = (180 - A)/2 = 45 degrees
