Ecursive formula f (n + 1) = f(n) – 2. If f(1) = 18, what is f(5)?

marishachu [46]

Answer:

$f(5) = 10$

Step-by-step explanation:

$f(n+1) = f(n)-2\\\\f(1) = 18\\\\f(1+1) =f(2)= f(1) -2 = 18 -2 = 16~~~~~~~~~~~~;[n=1]\\\\f(2+1) =f(3) = f(2) -2 = 16-2 = 14~~~~~~~~~~~~;[n=2]\\\\f(3+1) = f(4)= f(3) -2 = 14-2 = 12~~~~~~~~~~~~~;[n=3]\\\\f(4+1) = f(5) = f(4) -2 = 12 -2 = 10~~~~~~~~~~~~~~;[n=4]\\\\\text{Hence,}~ f(5) =10.$

What is the value of x

LenKa [72]

Answer: x= 98°

Step-by-step explanation:

Concept:

Here, we need to know the concept of the "Exterior Angle theorem"

The exterior angle theorem states that the measure of an exterior angle is equal to the sum of the measures of the two opposite angles of the triangle.

If you are still confused, you may refer to the attachment below for a graphical explanation.

Solve:

x = 53 + 45 = 98°

Hope this helps!! :)
