The slope is of $13, which means that each new sign costs $13.
-----------------
A linear function has the following format:
In which
- m is the slope, which is the rate of change, that is, how much y changes when x changes by 1.
- b is the y-intercept.
-----------------
- In the linear function in this problem, we have two points (x,y): (5,72) and (15,202).
- The slope is given by the <u>change in y divided by the change in x</u>, thus:
- The slope is of $13, which means that each new sign costs $13.

Answer:
yes 61.5 is correct
Step-by-step explanation:
Answer:
Step-by-step explanation:
This situation can be considered as a piecewise function. First, you take xo as the time in which the drone goes upward. Before this time the height of the drone is constant with a value of 5 m. Next, you take into account that during 1.9 s after xo the drone accelerates. Finally, the drone flies again with a constant height of 5.9m. Hence, this function has three parts:
For the first part you have:
y = 5 for x < xo
For the second part you first calculate vertical speed (which means the slope of the linear function) by using the following kinematic equation:
Then you have:
y = 0.47x for xo < x < xo + 1.9s
And for the third part:
y = 5.9 for x > xo + 1.9s
Summarizing you obtain:
