Answer:

Q = x^ b / x^c
Q = x^(b-c)
1 = x^ (b-c)
x^0 = x^ (b-c)
0 = b - c
b = c

Step-by-step explanation:

if the same base are in division then the powers are subtracted
x^0 = 1
if there is same base in an equation then the power of the base can be the equation

under a dilation, the point (2,6) is moved to (6,18) what is the scale factor of the dilation? enter your answer in the box

Anestetic [448]

Step-by-step explanation:

The equation of line passing through the two points is $\frac{y-y_{1} }{x-x_{1} }=\frac{y_{2} -y_{1}}{x_{2} -x_{1}}$

When substituted,the equation becomes $\frac{y-6}{x-2}=\frac{18-6}{6-2}$

which when simplified is $y=3\times x$

The line clearly passes through origin.

The distance between two points is $\sqrt{(y_{1}-y_{2} )^{2}+(x_{1}- x_{2} )^{2}}$

Distance between origin and $(2,6)$ is $\sqrt{40}$ .

Distance between origin and $(6,18)$ is $\sqrt{360}$

Scale factor is $\frac{distance\text{ }of\text{ }p_{2}\text{ from origin}}{distance \text{ } of \text{ } p_{1}\text{ from origin}}$

So,scale factor is $\frac{\sqrt{360} }{\sqrt{40} }$

which when simplified becomes 3.

A bag contains 6 red marbles, 4 black marbles, 10 green marbles, and 2 blue marbles. Marbles are taken at random from the bag, o

Inga [223]

Answer:

Step-by-step explanation:

First you will add them all up

6+4+10+2=22

Second find the black and green amount and add them together

4+10=14

Thirdly turn this into a fraction

14/22

Lastly simplify

14/11 / 2 = 7/11

An angle whose measure is 405° is in standard position. In what quadrant does the terminal side of the angle fall?

ohaa [14]

Quadrant I

405=360+45 405-360=45

405 is one complete counterclockwise rotation plus one half of an angle measuring 90 degrees counterclockwise rotation (=45)
