Here are the steps.
In order to get the answer, first we need to get the x and y value of the center of the circle by using the equation of a circle (x^2 + y^2 = r^2)
<span>The center is (-9, -4)</span>
Once you get the center point, find the equation of the line (in a form of a radius) from the center point to point (2, -1). Get the slope.
The slope from center to point (2, -1) is 11/3
Finally, get the negative reciprocal of the slope from the previous step and form the equation using slope-intercept form ( y=mx + b). Then, that's the equation of the tangent line.
The slope of the tangent line is -3/11
The equation is y = -3/11x - 5/11
Answer:
![\frac{2}{11}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B11%7D)
Step-by-step explanation:
First, find the probability of him pulling out a book.
There are 11 objects in total, and there are 4 books.
So, the probability of pulling out a book is ![\frac{4}{11}](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B11%7D)
Next, find the probability of him pulling out a DVD after.
Since a book was taken out, there are only 10 objects left. There are 5 DVDs.
So, the probability of pulling out a DVD is
, or simplified to ![\frac{1}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D)
To find the probability that this happens in order, multiply the probabilities:
x ![\frac{1}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D)
= ![\frac{2}{11}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B11%7D)
So, the probability is ![\frac{2}{11}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B11%7D)
Answer:
y=11
Step-by-step explanation:
your slope when you use y2-y1
---------
x2-x1
will become -12/0 so the equation will be y=11
May you add the statements so I can identify which one is true
