Answer:
the answer to #9 is (½, 1½)
Step-by-step explanation:
to find the midpoint, you need to use the midpoint formula
the midpoint formula is (x₁ + x₂ / 2 , y₁ + y₂ / 2)
for #9 you have to plug in the appropriate numbers in the formula
(-4 + 5 / 2 , 4 - 1 / 2)
(½ , 1½)
The area of a rectangular prism is found with the formula
2(wl+hl+hw)
where w is width, h is height, and l is length
The area is sqrt 664
I think pencil and paper would be the best method
Answer:
(-1.92, 1.08)
Step-by-step explanation:
The <em>incenter</em> is the center of the largest circle that can be inscribed in the triangle. That circle is called the <em>incircle</em>. The incenter is at the point of intersection of the angle bisectors. For a right triangle, the <em>inradius</em> (the radius of the incircle), is found from a simple formula:
r = (a + b - c)/2 . . . . . where c is the hypotenuse, and a and b are the legs
In your triangle, the inradius is ...
r = (5 + 3 -√(5² +3²))/2 = 4 -√8.5 ≈ 1.08452
Among other things, this means the coordinates of the incenter are about (1.08, 1.08) from the right angle vertex, so are about ...
incenter ≈ (-1.92, 1.08)
Is it supposed to be equal to something, maybe "0"? You wouldn't be able to solve this without that.
