Answer:
for the last question, there is a slope calculator on the internet that could help with that
Answer:
So we know the formula to calculate the area of the circular sector:
S=(r^2*π*a)/306°=
(5^2*3.14*40°)/360°= (1000*3.14) /360=8.72cm^2 so the right alternative should be the first one ,A.
Step-by-step explanation:
r - radius of the circle
a - corner of the circular sector
S - surface
Answer:
pretty sure it's A. (4, -4)
15 = 0.25x
1500 = 25x
60 = x
The original price was $60.
