Answer:
y = 5 cos ((2π/3)x - 2) + 2
Step-by-step explanation:
Cosine function takes a general form of y = A cos (Bx + C) + D
Where
A is the amplitude
2π/B is the period
C is the phase shift ( if -C, then phase shift right, if +C phase shift left)
D is the vertical displacement (+D is above and -D is below)
Given the conditions of the function to build and the general form, we can write:
** Note: period needs to be 3, so 2π/B = 3, hence B = 2π/3
Now we can write:
y = 5 cos ((2π/3)x - 2) + 2
first answer choice is right.
Answer: 480. Hope it helps! :)
Step-by-step explanation:first, you times 10 times 8, you get 80. then, you times it by six. Your answer is 480.
The equation would be .05x+50=100 Then you would solve for x

Answer:
D m = ![-\frac{3}{8}](https://tex.z-dn.net/?f=-%5Cfrac%7B3%7D%7B8%7D)
Step-by-step explanation:
factor the expressions in the denominator and the numerator to simplify the expression:
=> ![\frac{2(-2m + 1)(2m - 1)}{2(2m - 1)(8m + 3)}](https://tex.z-dn.net/?f=%5Cfrac%7B2%28-2m%20%2B%201%29%282m%20-%201%29%7D%7B2%282m%20-%201%29%288m%20%2B%203%29%7D)
=> ![-\frac{2m + 1}{8m + 3}](https://tex.z-dn.net/?f=-%5Cfrac%7B2m%20%2B%201%7D%7B8m%20%2B%203%7D)
to make a fraction undefined, the numerator should be 0, thus, we substitute the values of m from the options into the denominator to make the denominator equals to 0:
=>
=
= ![-\frac{2m + 1}{0}](https://tex.z-dn.net/?f=-%5Cfrac%7B2m%20%2B%201%7D%7B0%7D)
in this case, the values of m from option D make the denominator of the fraction equals 0.
