(b) |BD|

(c) |BC|

Step-by-step explanation:

An adapted diagram of this question is attached. You can vary the labelled letters as required.

<u>Definition</u>

A <u>radius </u>is a line drawn from the center of a circle to its circumference.
A <u>segment </u>is a line that connects two points.
A <u>diameter</u> is a chord which passes through the center of the circle.
A <u>chord</u> is any line joining two points on the circles' circumference.

By these definitions:

(a)Segments that are radii of this circle.

We have: |MA|, |MB| and |MC|

(b)Segment that is a diameter of this circle.

|BD|

(c)A chord of this circle that is not a diameter.

|BC|

Answer:

c. $2a^3x^4-3a^3x^3+a^4x^2$

d. $63x^5y^3-30x^2y^4-7x^3y^2$

Step-by-step explanation:

For this exercise you need to remember the following:

1. The multiplication of signs:

$(+)(+)=+\\(-)(-)=+\\(-)(+)=-$

2. The Product of powers property, which states that:

$(a^m)(a^n)=a^{(m+n)}$

3. The Distributive property:

$a(b\±c)=ab\±ac$

Knowing that, you can solve the multiplication of the polynomials:

c. $(-2ax^2+3ax-a^2)(-a^2x^2)=\\\\=(-2ax^2)(-a^2x^2)+(3ax)(-a^2x^2)+(-a^2)(-a^2x^2)=2a^3x^4-3a^3x^3+a^4x^2$

d. $(6.3x^3y-3y^2-0.7x)(10x^2y^2)=\\\\=(6.3x^3y)(10x^2y^2)+(-3y^2)(10x^2y^2)+(-0.7x)(10x^2y^2)=63x^5y^3-30x^2y^4-7x^3y^2$
