In a fibonacci sequence the fourth term is 30 and the fifth is 49 what is the first term
scoundrel [369]

8 is the first.

Reasoning:

So we know what the Fibonacci sequence is. To get the next number, you add the number behind it, by the number behind that.

For example, these are the first 5 Fibonacci numbers.

1, 1, 2, 3, 5.

1 + 0 = 1.

So 1 is the second number.

1 + 1 is 2.

So 2 is the third number.

2 + 1 = 3.

So 3 is the fourth number.

3 + 2 = 5.

So 5 is the fourth number.

The problem:

If the fifth term is 49, and the fourth term is 30. We can subtract 49 by 30, to find the third number, and so on.

49 - 30 = 19.

So 19 is the third number.

30 - 19 = 11.

11 is the second.

19 - 11 = 8.

8 is the first.

Answer: second option y = 2(x + 7/2)^2 + 1/2

Explanation:

1) given:

y = (x + 3)^2 + (x + 4)^2

2) expand the binomials:

y = x^2 + 6x + 9 + x^2 + 8x + 16

3) add like terms:

y = 2x^2 + 14x + 25

4) take common factor 2 of the first two terms:

y = 2 (x^2 + 7x) + 25

5) complete squares for x^2 + 7x

x^2 + 7x = [x +(7/2)x ]^2 - 49/4

6) substitue x^2 + 7x = (x + 7/2)^2 - 49/4 in the equation for y:

y = 2 [ (x + 7/2)^2  - 49/4] + 25

7) take -49/4 out of the square brackets.

y = 2 (x + 7/2)^2 - 49/2 + 25

8) add like terms:

y = 2(x + 7/2)^2 + 1/2

And that is the vertex for of the given expression.

What is the answer to the problem i am very confused...
musickatia [10]
The time of takeoff of this hovercraft would be 0 seconds, as if you were starting a timer. So, if you plug in 0 for x (unit for seconds) in your equation, it will look like this:

h(0) = -3(0 - 3)² + 108
Parenthesis first
h(0) = -3(-3)² + 108
Exponents next
h(0) = -3(9) + 108
Multiplication
h(0) = -27 + 108
Combine like terms

h(0) = 81: The height of the hovercraft at the time of takeoff is 81 meters!
Hope this helps :)
