Answer:7.5π
Step-by-step explanation:
Φ=360-90
Φ=270
Radius=r=5
Length of arc=Φ/360 x 2 x π x 5
Length of arc=270/360 x 2 x π x 5
Length of arc=0.75 x 2 x π x 5
Length of arc=7.5π
The domain of a function is the set of input or argument values for in which the function is real and defined. This is the definition of Domain. The function,y=x2+4x, has no undefined points or domain constraints. Therefore, the domain is - ∞ < x < ∞. (∞=infinity symbol)

86-49=37
LCM stands for least common multiple. We are being asked to find the lowest multiple that 6 and 15 have in common.
Multiples of a number (n) are integers that are the product of n and another number. Let's list the multiples of both 6 and 15:
6: 6, 12, 18, 24, 30, 36
15: 15, 30, 45, 60, 75, 90
The LCM of 6 and 15 is 30.
