What is the frequency of the function f(x)?

Mathematics
1 answer:
Alex73 [517]3 years ago
8 0

Answer:

  frequency = 1/(2π)

Step-by-step explanation:

The frequency of the function is found by comparing the argument of the cosine function to (2πfx), where f is the freuqency.

  2πfx = x . . . . the argument of the cosine is x in f(x)=2cos(x) -4

  2πf = 1 . . . . . . divide by x

  f = 1/(2π) . . . . . the frequency of the function f(x)

Which Exponential equation is equivalent to the logarithmic equation below? <br> C= in 3
Bess [88]

Answer

e^c = 3

Step by step explanation

The general exponential equation is y = a^x, where "a" is the base and "x" is the exponent.

We are given c = ln 3

Here the base is "e"

e^c = e^ln 3

e^c = 3             [base "e" and "ln" get cancelled because they are inverse]

Therefore, the answer is e^c = 3

Hope you will understand the concept.

Thank you.

A group of hikers walked 2 1/4 km in 3/4 hour.The distance here varies directly with time. What is the constant of variation?
telo118 [61]

The distance depends on the time.

So now we need to find the constant of variation or the constant of proportionality.

To do so we must find y(the dependent variable) and x(the independent variable).

To find the constant(k) we must find y/x

Since y/x=k

Then 2.25/.75=k

k=3

Find two consecutive even integers such that the square of the second, decreased by twice the first is 52
Fiesta28 [93]

Let the first integer be x. So, the next even number is x+2

Let's translate the formula: the square of the second is (x+2)^2, twice the first is 2x. So, the equation is

(x+2)^2 - 2x = 52

Expand the square to get

x^2+4x+4-2x = 52 \iff x^2+2x+4 = 52 \iff x^2+2x - 48 = 0

The solutions to this equations are

x = -8,\quad x = 6

So, the possible consecutive even numbers are

-8\text{ and } -6\quad\text{or}\quad 6\text{ and } 8
