Answer:
Standard form of a quadratic equation is;
ax^2+bx+c=0
According to the above equations, all of them are in standard form.
Step-by-step explanation:
The picture in the attached figure
we know that
The angle bisectors of a triangle intersect in a point (
incenter) that is equidistant from the three sides of the triangle
so
ZA=YA=XA-----> <span>are the radii of the inscribed circle
XA=3 cm
therefore
ZA=3 cm
the answer isZA=3 cm</span>
we know that
The volume of a cylinder is given by the formula
where
r is the radius of the cylinder
h is the height of the cylinder
in this problem

Substitute the values in the formula above


therefore
<u>the answer is</u>
The volume of the can is equal to

I hope this helps you
(5,-7) x'=5 y'= -7
(-7,1) x"= -7 y"=1
slope. (x'-x")=y'-y"
slope. (5-(-7))= -7-1
slope. 12= -8
slope =-8/12
slope = -2/3
