Answer:

The frequency of the tuning fork is 1760 Hz.

Step-by-step explanation:

Suppose we have a sine function in the following format:

y = A\sin{Bx + C}

The period is:

T = \frac{2\pi}{B}{/tex]The frequency, in Hz, is:[tex]F = \frac{1}{T}

In this question:

d = 0.6\sin{3520\pi t}

So

B = 3520\pi, T = \frac{2\pi}{3520} = \frac{2}{3520}, F = \frac{1}{T} = \frac{1}{\frac{2}{3520}} = \frac{3520}{2} = 1760

The frequency of the tuning fork is 1760 Hz.

Inscribed Angles - Find the value of x - WILL GIVE BRAINLIEST!
Gwar [14]

Answer:

137

Step-by-step explanation:

The degrees of the inscribed arc of 43 is 43 * 2 = 86

Since the total degrees in a circle is 360, x is equal to

(360-86)/2 = 137

Write the equation in y=(your answer) y is the y axis in coordinate plane.
Vitek1552 [10]

Answer:

y = 4

Step-by-step explanation:

Given the equation of the line, y = 6, passing through point (3, 4):

By definition, parallel lines have the <u>same slope</u>.

The linear equation, y = 6 is a horizontal line with a zero slope. Therefore, the parallel line must also have the same slope = 0.

Plug the given values from the point (3, 4) into the slope-intercept form:

y = mx + b

where:  y = 4, m = 0, and x = 3. We need to solve for the y-intercept, b:

y = mx + b

4 = 0(3) + b

4 = 0 + b

4 = b  

Therefore, the y-intercept is (0, 4).

For horizontal lines, the y-coordinate = 4 stays the same, while having different x-coordinates.

Therefore, the equation that is parallel to y = 6 is y = 4.

Which Trig. Function do you use to find X?
zvonat [6]

Answer:

Cosine

Step-by-step explanation:

Cosine = \frac{adjacent}{hypothenuse}

Cos 70 = \frac{x}{8}

0.633 = \frac{x}{8}

0.633 x 8 = \frac{x}{8} x 8

5.064 = x
