What is the frequency of the function f(x)?
Readme [11.4K]

Answer:

The frequency = 5/2π

Step-by-step explanation:

* Lets revise some facts about the trigonometry function

- If the function is f(x) = A sin (B x + C) + D  

* A is the amplitude  

- The amplitude is the height from highest to lowest points and  

 divide the answer by 2  

* The period is 2π/B  

- The period is the distance from one peak to the next peak

- Period and Frequency are related where frequency = 1/period

* C is the horizontal shift  

- The horizontal shift is how far the function is shifted to left  

 (C is positive) or to right (C is negative) from the original position.  

* D is the vertical shift  

- The vertical shift is how far the function is shifted vertically up

  (D is positive) or down (D is negative) from the original position.  

* Lets solve the problem

∵ f(x) = 3 cos (5x) + 2

∵ f(x) = A sin (B x + C) + D  

∴ A = 3 , B = 5 , C = 0 , D = 2

∵ The period = 2π/B

∴ The period = 2π/5

∵ The frequency = 1/period

∴ The frequency = 1/(2π/5) ⇒ multiply up and down by 5

∴ The frequency = 5/2π

Evaluate 0.985 using the Binomial Theorem. Write 0.98 as a binomial: (1 -0.02 ) Enter the value for each variable. a
kati45 [8]

Using binomial theorem. The value of 0.98^5 is 0.9039207968.

|Using the binomial theorem, we get

0.985 Co(1)5 +5 Ci(1)'(-0.02)1 +5 Ca(1"(-0.02) +5 Ca(1)P(-0.02)3 +5

C(1)(-0.02)+5 Cs(1)°(-0.02)

0.98=(1) + 5(-0.02)'+ 10(-0.02)? + 10(-0.02)3 +5(-0.02) + 1(-0.02)5

0.98 (1)+(-0.1) + (0.004)+ (-0.00008) +0.0000008+ (-0.0000000032)

0.98-0.9039207968.

The binomial theorem, the statement that for any positive integer n, the sum of two numbers a and b raised to the power n can be expressed as the sum of n + 1 terms of the form Yoki's triangle. Key Person: al-Karajī Bernhard Bolzano Related Topics: Triangular binomial coefficients of Algebra Pascal.
