snow_lady [41]

Answer:

The correct answer is 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89.

Step-by-step explanation:

In a study of the progeny of rabbits, Fibonacci encountered the sequence now bearing his name.

The sequence is defined recursively as:

a_{n+2} = a_{n} + a_{n+1}, where a1 = 1 and a2 = 1 where n is a natural number.

For n = 0 ; a2 = a0 + a1

⇒ a0 = 0.

For n = 1 ; a3 = a1 + a2 = 1+1

⇒ a3 = 2.

For n = 2 ; a4 = a2 + a3 = 1+2

⇒ a4 = 3.

For n = 3 ; a5 = a3 + a4 = 2+3

⇒ a3 = 5.

For n = 4 ; a6 = a4 + a5 = 3+5

⇒ a6 = 8.

For n = 5 ; a7 = a5 + a6 = 5+8

⇒ a7 = 13.

For n = 6 ; a8 = a6 + a7 = 8+13

⇒ a8 = 21.

For n = 7 ; a9 = a7 + a8 = 21+13

⇒ a9 = 34.

For n = 8 ; a10 = a8 + a9 = 21+34

⇒ a10 = 55.

For n = 9 ; a11 = a9 + a10 = 55+34

⇒ a11 = 89.

Thus the first 12 terms of fibonacci sequence is 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89.

An equilateral triangle has an apothem of 5 cm. Find the perimeter of the triangle to the nearest centimeter.
Dennis_Churaev [7]
The apothem is the distance from which the altitudes of the triangle to one of its sides. It can be calculated through the equation below,
                             tan 30° = apothem / 0.5(length of side)
Substituting the known values,
                             tan 30° = 5 / 0.5x
The value of x from the equation above is 17.32. Multiplying this value by 3 (because a triangle has 3 sides), we get an answer of 51.96 cm or approximately equal to 52. Thus, the answer is letter B.

Help me on this please

Answer:

  • sin(θ) = 4/5
  • cos(θ) = 3/5
  • tan(θ) = 4/3

Step-by-step explanation:

The mnemonic SOH CAH TOA was created to help you remember the relevant trig relationships. It is intended to remind you ...

  Sin = Opposite/Hypotenuse

  sin(θ) = 4/5

  Cos = Adjacent/Hypotenuse

  cos(θ) = 3/5

  Tan = Opposite/Adjacent

  tan(θ) = 4/3

__

In a right triangle, the opposite side (PQ) is the one that is not part of the angle (∠R = θ). The adjacent side (QR) is the shorter side that makes up the acute angle. The longest side (PR) is the hypotenuse.
