It
is a linear function because the rate of change is constant: for each
increase of 1 unit in x, there is a decrease of 4 units in y: ⇒ slope = - 4
Remember to include the two points
of intersection in your table. Analyze the two functions; they are there (0,36) and (4, 20)
Answer the
following reflection questions in complete sentences. What is the domain
and range of the rainbow?
Explain what the domain and range represent.
Do all of the values make sense in this situation? Why or why not? What
are the x- and y-intercepts of the rainbow? Explain what each intercept
represents.
The domain is all the real values of x between - 6 and 6: - 6 ≤ x ≤ 6
The range is all the values between 0 and 36: 0 ≤ y ≤ 36
The domain represents the horizontal distance between the extremes of the rainbow at the ground.
The range represents: the altitude of the rainbow from the ground (y = 0). The height is at x = 0, y = 36.
The x-intercepts are - 6 and 6, that is the opening of the rainbow at the ground level.
The y-intercept is when x = 0, it is y = 36, and is the height of the rainbow.
Is the linear function you created positive or negative?
Explain. What are the solutions or solution to the system of equations
created? Explain what it or they represent.
The linear function is positive and decreasing. It is positive because it goes above the x-axis, this is y ≥ 0.
The solutions where already signaled: (0,6) and (4, 20). They are the points at which the drone intercepts the rainbow.
Answer:
360°
Step-by-step explanation:
It would be the same thing as finding the sum of a rectangle where all 4 angles add up to 360° or think of it as a circle where circles = to 360° (I hope this makes sense)
C
im pretty sure...
that's the only one that makes sense because X has to be less than any of the other answers. from what i see from the diagram
