study the equations:
f(x)=11x-5
g(x)=-2x-4
what is h(x)= f(x) g(x)?
a) h(x)=-22x^2+34x+20
b) h(x)=-22x^2+10x-24
c) h(x)=22x^2-54x+20
d) h(x)=-22x^2-34x+20

D.

Step-by-step explanation:

h(x)=f(x)g(x) means multiply the expression for f to the expression for g.

That is the problem is just asking you to do (11x-5)(-2x-4).

Let's use foil.

First:  11x(-2x)=-22x^2

Outer: 11x(-4)=-44x

Inner: -5(-2x)=10x

Last: -5(-4)=20

Add together!

-22x^2-34x+20

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30
