Angle = 36 degrees =
=
now, radius = 10 cm
so arc = radius x angle = 10 x pi/5 = 2pi = 6.28 cm
1) 4 meters = 400 centimeters
2) 8 centimeters = 80 centimeters
3) 9 meters = 9,000 millimeter
Your answer is: 400; 80; 9,000
Have an amazing day and stay hopeful!
Answer:
x = i sqrt(14/19) or x = -i sqrt(14/19)
Step-by-step explanation:
Solve for x:
(-38 x^2 - 28)/(x^2 - 5 x - 2) = 0
Multiply both sides by x^2 - 5 x - 2:
-38 x^2 - 28 = 0
Add 28 to both sides:
-38 x^2 = 28
Divide both sides by -38:
x^2 = -14/19
Take the square root of both sides:
Answer: x = i sqrt(14/19) or x = -i sqrt(14/19)
161/4=40.25 so none of those choices match
It’s the last one, -2 and 1/3
