Answer:
The arc length is 87.5 inches.
Step-by-step explanation:
Given that,
Arc length = S = ?
Angle = theta = 100°
Radius = r = 50 inches
The relation between the arc length (S), angle (theta) and radius (r) is calculated using 
However, the angle should be in radian.
To convert degrees into radian, we use: 
=> 
=> 1.75 radian
By putting values in the above relation, we get
Therefore, the arc length is 87.5 inches.
2(3x - 1) ≥ 4x - 6 | Starting equation
6x - 2 ≥ 4x - 6 | Distribute the 2
2x - 2 ≥ -6 | Subtract 4x from each side
2x ≥ -4 | Add -2 to each side
x ≥ -2 | Divide both sides by 2
So, x must be greater or equal to -2 to be in the solution set.
Tap on it and that's the answer.
Answer:
x=4+√5 or x=4−√5
Step-by-step explanation:
Multiply both sides by x-4.
x2−8x+16=5
x2−8x+16−5=5−5(Subtract 5 from both sides)
x2−8x+11=0
For this equation: a=1, b=-8, c=11
1x2+−8x+11=0
x=
−b±√b2−4ac
2a
(Use quadratic formula with a=1, b=-8, c=11)
x=
−(−8)±√(−8)2−4(1)(11)
2(1)
x=
8±√20
2
x=4+√5 or x=4−√5
