65 is the answer. Solve the first equation and then plug in.
Let's start with our parent function:
f(x) = sin x
One cycle on this graph occurs between 0 and 2π. Therefore, our b-value is one.
There is no vertical shift up. The sinusoidal axis is along y = 0.
The wave is not inverted, it starts at the origin and rises on both the y and x axis. Thus there is no negative value before the function.
The amplitude of the wave is 3. A normal sine wave rises to a maximum of 1, but this is multiplied by 3.
f(x) = 3 sin x
There are an infinite amount of equations that could be used to represent this graph, but this is perhaps the most intuitive.
Answer:
2 < x <_ 3.5
Step-by-step explanation:
First, find the value of x by writing it as an equation. Then, use 0 as x to determine the correct inequality.
It would be 2 because 2 divide 2 is 1
Answer:
(-3,-10)
Step-by-step explanation:
Given part a, you seem to know the midpoint formula. We can easily edit that to figure out what an endpoint is. Say that a variable "a" represents the x coordinate of D, and b the y coordinate. As the x coordinate of M is 0.5, and the x coordinate of C is 2, we can use the midpoint formula to say that 
. Multiplying both side by 2, we get that a+2=-1, and subtracting both sides by 2, a=-3. Similarly, 
, b+7=-3, and b=-10, making our answer (-3, -10). Let me know if you have any questions.
