Answer:
You get an perpendicular line through given point.
Step-by-step explanation:
In this method of drawing perpendicular line through given point,
you will draw an arc from given point R, so as to cut given line at A and B.
now ,length RA will be equal to length RB (radius of circle)
now, with length RA you will place compass at A and B to cut the arcs at point P (let) on other side of given line.Now, join PA and PB.
The closed RAPB makes a rhombus and diagonal bisect perpendicularly in rhombus.
so you get an perpendicular line through given point.
Answer:
D. 14
Step-by-step explanation:
4a+ b - 5
4(4) + 3- 5
16+ 3 - 5
19-5 +14
we
know that if we have a polynomial with real coefients and one root is
a+bi, another root is a-bi
so
some
roots are
3,-4,6+5i,
6-5i
for
roots, r1 and r2
teh
factors are
(x-r1)(x-r2)
so
we
can put them in and
(x-3)(x+4)(x-6-5i)(x-6+5i)
(x^2+x-12)(2x^2-12x+61)
x^4-11x^3+37x^2+205x-732
to
keep the same coefients, we multiply whole thing by c
c(x^4-11x^3+37x^2+205x-732)
we
don't know what c is
we
know that
f(1)=250
f(1)=c(x^4-11x^3+37x^2+205x-732)
find
c
f(1)=c(1^4-11(1^3)+37(1^2)+205(1)-732)=250
f(1)=c(-500)=250
-500c=250
divide
both sides by -500
c=-1/2
the
polynomial (factored with real coefients) is
f(x)=-0.5(x-3)(x+4)(2x^2-12x+61)
