Answer:
p=2
Step-by-step explanation:
(3+6i) and (4+pi) is (7+8i)
3+4 = 7
6i+pi = 8i
Subtract 6i from each side
pi = 8i-6i
pi = 2i
That means p = 2
Answer:
D.130°
Step-by-step explanation:
An arc measure ia an angle an arc makes with the circle's centre and is proportional to the angle it subtends to the circumference, arc length.
-Given that AC and BC are diameters, then
since they are alternate angles.

#Since angles on one side of a diameter sum up to 180°, mBC is calculated as:

Hence, mBC=130°
Answer:
0.488
Step-by-step explanation:
Add 0.2+0.16+0.128+0.512 which is 1
Then subtract 0.512 and you get 0.488
I know there is probably a simpler way but this is how I did it
Answer:
33
Step-by-step explanation:
396/x - 10 = -22
add 10 to each side
396/x = -12
multiply both sides by x
396 = 12x
divide both sides by 12
33 = x
