What is the length of arc S shown below?
2 answers:
Answer:
s = 2
Step-by-step explanation:
The length of the arc s is calculated using
s = circumference × fraction of circle
= 2πr × ( cancel 2π )
= 5 × 0.4 = 2
Answer:
Length of arc S = 2 units
Step-by-step explanation:
Circumference of the circle = 2πr
Here r = radius of the circle
Now length of the intercepted arc by the sector will be
S = Length of Circumference ×
S = [Angle inscribed by the sector is 0.4 radians]
= 0.4r
= 5 × 0.4
= 2.0 units
Therefore, length of arc S is 2 units.

Sum of the roots of the polynomial
<u>Solution:</u>
The general form of cubic polynomial is ---- (1)
If we have any cubic polynomial having roots
Sum of roots =
---(2)
From question given that,
--- (3)
On comparing equation (1) and (3), we get a = 1, b = 2, c = -11 and d = -12
Hence the sum of roots using eqn 2 is given as,
=
= -2
Hence the sum of the roots of the polynomial
