The tangent of an angle is the ratio of the opposite side to the adjacent side.
... tan(45°) = (height above eye level)/(20 m)
... height above eye level = (20 m)·tan(45°) = (20 m)·1 = 20 m
_____
Eye level is 1.7 m above ground, so the height of the flagpole above ground is
... height of pole = height above eye level + height of eye level
... height of pole = 20 m + 1.7 m = 21.7 m
Well, a linear function is proportional, a straight line (on a graph). And the numbers must not have the same answer. For instance, if the X input is 5, and the Y output is 7. And then another X input is 5, and the Y output is 8, that's non-linear.
So, the Answer would be the third graph. This is because the X values are steadily increasing, and so are the Y values.
For the X and Y values, for each time X increases by 1, Y increases by -8. This is, linear because both sides are constantly and evenly increasing.
Answer:
0
Step-by-step explanation:
the answer is 0
because it neither rises nor fall
Answer:
15
Step-by-step explanation:
y=mx+b
b is the intercept
in this equation "m", the slope, would be one. the y-intercept, or "b" would be 15

The formatting was a bit confusing, so please do let me know if this isn't the correct equation for the sequence.
The first term is given, which is

Now, use the equation for the next terms:



Thus, the first 4 terms are -9, -8, -6, and -3. Let me know if you need any clarifications, thanks!
