In the given triangle , Coordinates of A (-1,3) , B (-5,-1), C (3,-1).
Let's find the slope of AB and AC .
Formula of slope is
For AB, slope is,
And slope of AC is
Product of the slopes of AB and AC is
Since the product of the two slopes is -1, so AB and AC are perpendicular.
And if they are perpendicular, angle BAC is 90 degree, so the triangle is right triangle .
Now we check the length of the sides of the triangle, and for that we use distance formula , which is
So for AB,
For AC,
For BC,
And since two sides are equal, so the triangle is isosceles triangle .
The hundreths place of 0.44 is the second 4, aka 0.4(4) <-- this digit.
The digit in the tenths place is 0.(4)4 <--- the one circled by the brackets.
So the value of the digit in the hundreths place is 0.04, while the value of that in the tenths place is 0.4~
You should be able to get to the answer from here, if not, I'll be here to answer/follow through~ :)
we need a picture so we can help you

If
you want to express the vertex form of an equation you have to know
that the vertex form of a parabola’s equation can be expressed as:
y = a(x - h)</span>²<span> + k. The way you know how the parabola will look like
is:
If
a is positive then the parabola opens upwards like a U.
If
a is a negative number, then the graph will open downwards like an
upside down U.
