A strobe light is located at the center of a square dance room. the rotating light is 40 feet from each of the square walls and
Effectus [21]

The equation of the rotating light is an illustration of a secant function

The equation that represents the distance between the center of the circle and the light source is d(t) = 40\sec(\frac{\pi}{3}t)

<h3>How to determine the equation</h3>

The equation is a secant function represented by

y =A\sec(Bt)

Where:

A represents the amplitude

So, we have:

A = 40 --- the distance of the light from each square wall

B represents the period, and it is calculated as:

B = \frac{2\pi}{T}

The light completes its full rotation every 6 seconds.

This means that,

T = 6

So, we have:

B = \frac{2\pi}{6}

Simplify

B = \frac{\pi}{3}

Substitute values for A and B in y =A\sec(Bt)

y = 40\sec(\frac{\pi}{3}t)

Rewrite as a function

d(t) = 40\sec(\frac{\pi}{3}t)

Hence, the equation that represents the distance between the center of the circle and the light source is d(t) = 40\sec(\frac{\pi}{3}t)

An item that originally costs $320 is on sale for 22% off. What is the sale price? Show your work. PLZ SHOW UR WORK!
Mnenie [13.5K]

<u>Answer:</u>

The answer is $249.60

<u>Step-by-step explanation:</u>

This is a simple question. Firstly you will take the total cost and multiply it by 0.22. The answer to this is 70.4. Take that and subtract it from the total cost because 70 is the discount price. Once subtracted you will get 249.6. In conclusion, the sale price of the item is $249.60.

P.S. I hope this answer helped you in some way or another. If you have any questions you can ask them to me and I will be happy to help you out. I also wanted to add that I have a channel called The Game Rater or soon to be Nitro Studios (based on when you see this). I would really appreciate it if you could check out my channel. If not, I hope this answer helped you and I still appreciate you reading this side note. Thank you.
