Answer:
The answer is B) y = Sin(3x)
Step-by-step explanation:
In order to find this, you need to look for how long it takes the period to repeat. This means other than the origin, we need to find the next place that the graph hits y = 0. In this case, it is at 2/3. Since Sin2
= 0, we need what is inside of the parenthesis to equal 2
.
The only thing that you could multiply 2/3 by to get 2
m is 3. Therefore, we must have 3x in the original equation.
Answer:
1) These linear functions must not describe a pair of parallel lines.
2) Any intersection of two lines determines a point.
Step-by-step explanation:
Hi there!
Well, since no further details were given. Let's call the linear function that represents the number of animals adopted from the shelter . And
the hours the volunteers work at the shelter each week
1) These linear functions must not describe a pair of parallel lines.
If these lines intersect, then their slope must be different.
Equal slopes, parallel lines. Parallel lines, no intersection.
Different slopes, then there is an intersection at some point.
2) Any intersection of two lines determines a point. Let's find it.
So to find one common point equalize the two functions, then find the value for the x-coordinate. Plug it in one of the functions, e.g.
At the common point, both functions after inserted the same value in the Domain (x) return the same result for their respective Range set.
