Find an equation of cosine function with maximum of 7, minimum of -7 and period of 7
Galina-37 [17]

Answer:   \bold{y=7cos\bigg(\dfrac{2\pi}{7}x\bigg)}

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

y = A cos (Bx - C) + D

  • A = amplitude (vertical stretch)
  • Period = 2π/B
  • C/B = phase shift
  • D = vertical shift

The minimum is -7 and the max is 7 so A = 7 and D = 0

Period is 7.  Since P = 2π/B then 7 = 2π/B --> B = 2π/7

Nothing was stated about a phase shift so you can use any value for C. I chose C = 0.

Now, input A = 7, B = 2π/7, C = 0, & D = 0 into the equation

y=7\cos\bigg(\dfrac{2\pi}{7}x-0\bigg)+0\\\\\\\text{Simplify}:\\y=7\cos\bigg(\dfrac{2\pi}{7}x\bigg)

If a rectangle or prism has a volume of 432 in.³ and the height of the prism is 9 inches what are the dimensions of the base
Deffense [45]
You first do 432 divided by 9 which is 48. However, there could be multiple dimensions for the base because 48 is a composite number. One example could be 6 by 8
