Answer

(f ο g)(2)= 1/17 =0.058 and (f+g)(2)= 17.5

Step-by-step explanation:

f(x)=1/x ; f(2)=1/2

g(x)=4x+9 ; g(2)=4(2)+9

As,

1. (f ο g)(x)=f(g(x)) (Composite Function)

(f ο g)(2)=f(g(2))=f(4(2)+9)=f(8+9)=f(17)=1/17

=0.058 (in decimal)

2. (f+g)(x)= f(x)+g(x) (Sum of Functions)

(f+g)(2)=f(2)+g(2)=1/2 +(4(2)+9)=1/2+(8+9)=1/2+17 (taking L.C.M)

=[1+17(2)]/2=(1+34)/2=35/2

=17.5 (in decimal)

Answer:

maximum: (x, y) = (12.4n+3.2, 186.322)
minimum: (x, y) = (12.4n+9.4, 163.498)

Step-by-step explanation:

You know that cos(α) is a maximum at α=0, 2π, 4π, and all even multiples of π. You know cos(α) is a minimum for α=π, 3π, 5π, and all odd multiples of π.

You can find your value of x at which y will be a maximum by setting the argument of the cosine function equal to zero (and/or 2nπ). If we use α=2nπ, then we have ...

α = (5π/31)(x -3.2) = 2nπ

(x -3.2) = (31/5)(2n) = 12.4n

Tidal maxima will occur at ...

x = 12.4n +3.2 . . . . . for integer values of n

Without bothering to go through the solution for α being odd multiples of π, we can see from this that the period is 12.4 hours. We know the tidal minimum will be half a period later, or 6.2 hours later than this.

Tidal minima will occur at ...

x = 12.4n +9.4 . . . . for integers n

Of course, cos(α) has extremes of ±1, so your tidal maximum will be ...

y = 11.412 +174.91 = 186.322

and your tidal minimum will be ...

y = -11.412 +174.91 = 163.498
