The cost of frozen yogurt without any toppings is $2.25. The cost of each individual topping is $0.25. The amount of toppings is represented by x.

The total cost of a frozen yogurt would be given by the following function:

y = 2.25 + 0.25x

What is the equation of the midline for the function y = 3cos(x - π ) - 4?
andrezito [222]

<u>Answer:</u>

The correct answer option is y = -4.

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

We are to find the equation of the mid-line for the following function:

y=3cos(x-\pi)-4

3 cos((x - \pi ) - 4 = 3 cos(x) - 4 because cos(x-\pi) = cos(x)

-1 \leq cos(x) \leq 1

-3 \leq 3cos(x) \leq 3

-3-4 \leq 3 cos(x)-4 \leq 3-4

-7 \leq 3 cos(x)\leq-1

The range is -7 to -1 so the midpoint is \frac{-7-1}{2} =-4

Therefore, the equation of the mid-line for the given function is y = -4.

Answer:

-1

Step-by-step explanation:

Note that i+i^2+i^3+i^4 = i-1-i+1 = 0, and this means that every 4 terms, the terms cancel to 0. Therefore, by taking modulo 4, we only need to find i^{257}+i^{258}+i^{259} = i-1-i = -1 since $i$ has a cycle of 4.
