shi ion even know
Step-by-step explanation:
good luck tho
If 52 ft. is one of your answers i would say 52, sorry if im wrong
Answer: ![\bold{y=7cos\bigg(\dfrac{2\pi}{7}x\bigg)}](https://tex.z-dn.net/?f=%5Cbold%7By%3D7cos%5Cbigg%28%5Cdfrac%7B2%5Cpi%7D%7B7%7Dx%5Cbigg%29%7D)
<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)](https://tex.z-dn.net/?f=y%3D7%5Ccos%5Cbigg%28%5Cdfrac%7B2%5Cpi%7D%7B7%7Dx-0%5Cbigg%29%2B0%5C%5C%5C%5C%5C%5C%5Ctext%7BSimplify%7D%3A%5C%5Cy%3D7%5Ccos%5Cbigg%28%5Cdfrac%7B2%5Cpi%7D%7B7%7Dx%5Cbigg%29)
D. You start out with $500, it does not use a variable, knocking out a and b. Also, you need at least the needed amount of money, so b or c cannot be the answer. This only leaves d.
Answer:
C is false
Step-by-step explanation:
Example 3 is odd but 6 is equal.
3•6 is 18
18 is even
