Answer:
f(3) = 3
Step-by-step explanation:
f(1) = 1
f(2) = 2
f(n) = f(n − 2) + f(n − 1)
f(3) = f(3 - 2) + f(3 - 1)
= f(1) + f(2) = 1 + 2 = 3
Special Note: Have you heard of the Fibonacci sequence?
The formula f(n) = f(n − 2) + f(n − 1) is used to find the terms of the of the Fibonacci sequence
The given quadratic expression; 5b² -6b -2 is prime because the discriminant is not a perfect square.
<h3>
What is the discriminant of the expression?</h3>
According to the task content; it is required to identify if the expression is prime.
On this note, it follows that the discriminant of the expression can be evaluated as follows;
= 36 -(4× 5 × -2)
= 76.
Hence, the expression is prime since 76 is not a perfect square.

Answer:
$18360
Step-by-step explanation:
Since, the value decreased by 40%, the price is (100-40)% of 34000
= 60% of 34000
= 60/100 * 34000
= 60 * 340
= 20400 --- (Price after first year)
Since, the value decreased by 10%, the price (100-10)% of 20400
= 90% of 20400
= 90/100 * 20400
= 90 * 204
= $18360
