Answer:
m = rise / run = 1/7
Step-by-step explanation:
Recall that the slope of a line is m = rise / run.
Here we look at x first (to calculate the run): x begins at -7 and ends at 0. Thus, the run is 0 - (-7), or 7.
Now look at how y behaves (find the rise): y begins at 0 and ends at 1. Thus, the rise is 1.
Therefore the slope of the line connecting the two poings given is
m = rise / run = 1/7
Answer:
a)
<u>The angle formed by intersecting chords is half of the sum of the intercepted arcs:</u>
- 1/2(mST + mPR) = m∠PUR
- 1.2(74° + mPR) = 77°
- 74° + mPR = 2*77°
- mPR = 154° - 74°
- mPR = 80°
b)
<u>The angle formed by two tangents is the half of the difference of the intercepted arcs:</u>
- m∠PSR = 1/2(mPTR - mPR)
- m∠PSR = 1/2(247° - (360° - 247°))
- m∠PSR = 247° - 180°
- m∠PSR = 67°
Well you have to make the powers line up so we know r^4 is the highest and you work your way down so
0r^4-5r^3-4r^2-3r
R^4+0r^3-4r^2+3r
So now that they are lined up by power we solve (keep in mind that the 0r's are place holders and have no value)
R^4-5r^3-8r^2
That's your answer

Step-by-step explanation:
Answer: 1500 readers
explanation: all readers take up 100%
100/50=2
100% / 50 = 2%
2% x 50 = 100%
30 x 50 = 1500 readers
