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
Hello.
A scale factor is a term that defines the multiplicative/divisive measurement difference between the two same shapes. The way we can find our scale factor is by dividing our new measurement by the old measurement.
681 / 3 = 227
Our scale factor is 1/227, as 3 is 1/227 of 681 - and we are looking for the scale factor to find what multiplied by 681 would give us 3.
I hope this helps!

Considering a six-sided spinner, it is found that the probability of spinning a 1 and tossing a head is of
.
<h3>What is a probability?</h3>
A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
In this problem:
- For the spinner, one is one out of six possible outcomes.
- For the coin, a head is one out of two possible outcomes.
Since the events are independent, the probability of spinning a 1 and tossing a head is given by:
.
