Answer:
Step-by-step explanation:
Area of sector = (∅/360°) x πr²
Area of sector = 48cm²
radius = 4cm
π = 3.14
48 = (∅/360°) x 3.14 x 4 x4
48 = (∅/360°) x 50.24
48/50.24 =(∅/360°)
0.9554 = (∅/360°)
∅ = 0.9554 x 360 = 343.949≈343.95° ( these is when the angle is in degrees)
if it is radians
area of sector = 1/2r²∅
area of sector = 48
r = radius = 4
area of sector = 1/2r²∅
48 = 1/2 x 4 x4 x∅
48 = 2x4 x∅
48 = 8∅
∅ = 48/8 = 6 radians
the central angle in radians is 6
The answer is x bc when you decreasing the interval f(x) it will equal (-2)
Answer:
$500
Step-by-step explanation:
You hand him 100%
He pays back 140%(original amount plus 40%)= 700
Original amount =x
700/140 = x/100
140x=700*100
140x = 70,000
x=500
200 is the 40% of 500
500+200= 700
