Answer:

False

Step-by-step explanation:

Correct me if I'm wrong but this suppose to be a true or false question.

The measure of angle of B is going to be half the arc measure of AC so they don't have the same measurement. If they don't have the same measurement, then they can't be congruent.

Answer:

The resultant expression is $2x^{2}+5x^{2}-x-6$ .

Step-by-step explanation:

The distributive property of multiplication is:

$a\times (b+c)=(a\times b)+(a\times c)$

The two polynomials provided are:

$(2x+3)\\(x^{2}+x-2)$

Determine the final expression by multiplying the two polynomials as follows:

$(2x+3)\times (x^{2}+x-2)=[2x\times(x^{2}+x-2)]+[3\times(x^{2}+x-2)]$

$=[(2x\times x^{2})+(2x\times x)-(2x\times 2)]+[(3\times x^{2})+(3\times x)-(3\times 2)]\\\\=[2x^{3}+2x^{2}-4x]+[3x^{2}+3x-6]\\\\=2x^{3}+2x^{2}+3x^{2}-4x+3x-6\\\\=2x^{3}+5x^{2}-x-6$

Thus, the resultant expression is $2x^{2}+5x^{2}-x-6$ .

in a video game an object represented by the point is rotated counterclockwise 350 degrees about an origin. what are the new coo

If the point (3,2) is rotated counterclockwise 350 degrees about an origin, then the new coordinates if new point will be (3.28,1.44).

Given that the point is (3,2) and the point is rotated counterclockwise 350 degrees about an origin.

We are required to find the new coordinates.

Origin is a point where both the values of x and y are equal to zero.

a=arc tan (2/3)=33.7

r= $\sqrt{3^{2} +2^{2} }$

= $\sqrt{13}$

b=a+350

=33.7+350

=383.7 degrees

x=r cos b= $\sqrt{13}$ cos 383.7= $\sqrt{13}$ *0.91=3.28

y=r sin b= $\sqrt{13}$ sin 383.7= $\sqrt{13}$ 80.40=1.44

Hence if the point (3,2) is rotated counterclockwise 350 degrees about an origin, then the new coordinates if new point will be (3.28,1.44).
