Answer:
cos(x)+1 or cos x + 1
Step-by-step explanation:
The wave starts at y=2 this means it is a cosine function, then the first positive x-intercept is at about (pi, 0) which is about 3, this leads to cos x + 1 as the answer.
Lets say she cuts squares of x by x in length.
Area of bottom will be (20 - 2x)(11 - 2x) = 80 inches squared
220 - 40x - 22x + 4x^2 = 80
4x^2 - 62x + 140 = 0
x^2 - 15.5x + 35 = 0
Using quadratic equation;
you get x = 2.743753901 0r 12.7562461 inches
The length of the square cannot be more than 11 inches
So the only squares you can cut are:
2.743753901 inches by 2.743753901 inches squares.
That "equation" has an infinite number of "solutions", because
no matter what 'r' is, it's always a true statement.
The statement is equivalent to saying "I am I." or "You are you."
150 + 30 = 180, right? We need to find 180 on the other side.
180 - 2 = 178
178 / 4 = 44.5
The answer is most likely 44.5. Let me know if I am wrong,
