If f(x)=3(x+5)+4/x, what is f(a+2)?

3(a + 7) + 4/(a + 2)

Step-by-step explanation:

f(x) = 3(x + 5) + 4/x

Substitute:

x = a + 2

f(a + 2) = 3(a + 2 + 5) + 4/(a + 2)

= 3(a + 7) + 4/(a + 2)

step-by-step explanation:

arc length = 6.63311 ft.

step-by-step explanation:

the formula the arc measure is:

arc length s=2πr(c)/360

where:

c   is the central angle of the arc in degrees

r   is the radius of the arc

π   is pi, approximately 3.142

using the above formula we get

s =

thus we find that arc length of an arc for a circle of radius 20 feet and central angle 19 degrees is

6.63311 feet
