Answer:
Ф = s/r
Step-by-step explanation:
The arc length formula is s = rФ, where r is the radius and Ф is the central angle. We want to find a formula for the angle Ф in terms of s and r. To do this, start with s = rФ and divide both sides by r:
s rФ
-- = ----
r r
Then Ф = s/r
Answer:
Solution answer is 24
Step-by-step explanation:
=8 x 4 + 9 - 9 + 8
using D M A S rule
=32 + 9 - 9 +8
=41 - 17
=24

Answer:
There are 1680 different ways four letters can be arranged.
Since you are using the permutation formula, plug in the values and solve.
P(n,r) = P(8,4)
= 8! / (8−4)!
= 1680
Spelling out LION is only one of the 1680 possible outcomes. Therefore the fraction 1/1680 would represent this probability.
P(LION) = 1/1680
