Answer:
item 30.
d. 1 ½ as we can see the difference between the each x value is 2 and y value is more of 1 and 2.
items 31.
a. ⅖ as similar to upper question the difference between each x value is 2 and y value is 5 so ⅖
Answer:
Arc BC = 117°
Step-by-step explanation:
Angle D is an inscribed angle that intercepts arc ABC. According to the Inscribed angle theorem of a circle, m<D = ½ of arc ABC.
Thus,
104° = ½(AB + BC)
104° = ½(91° + BC)
Multiply both sides by 2
104*2 = 91 + BC
208 = 91 + BC
Subtract both sides by 91
208 - 91 = BC
117 = BC
Arc BC = 117°

Step-by-step explanation:
The better way to obtain roots of a polynomial when is not easy to analytically factorize is to use software as Matlab or Python. Use the following code in Python
import numpy as np
pol=np.array([1,-0.2589, 0.02262,-0.001122])
roots=np.roots(pol)
print(roots)
