What is the frequency of d=9cos(pi/2 t)

1 answer:

5 0

The period is equal to 2pi/n, where n is the coefficient of t. In this case pi/2. Therefore the period in this example is 4. Frequency is equal to 1/period. Hence the frequency for this problem is 1/4

Answer:

$x = 2\sqrt{2}, -2\sqrt{2}$

Step-by-step explanation:

Given

$x^2 - 8 = 0$

Required

Solve

We have:

$x^2 - 8 = 0$

Add 8 to both sides

$x^2 = 8$

Take square roots of both sides

$x = \±\sqrt{8}$

Expand

$x = \±\sqrt{4*2}$

This gives:

$x = \±2\sqrt{2}$

Split

$x = 2\sqrt{2}, -2\sqrt{2}$

the value of y varies directly with X. Which function represents the relationship between X and Y if y equals 15/6 when x equals

Maru [420]

Answer:

y = (1/8)x

Step-by-step explanation:

The relevant basic formula is y = kx, where k is the constant of proportionality.

We must find k. To do this, let y = 15/6 and x = 20 in the above formula:

15/6 = k(20)

We solve for k by dividing both sides by 20: 15/(6*20) = k = 1/8

Then the specific formula for this situation is y = (1/8)x
