Answer:
Step-by-step explanation:
The figure is made up of a rectangle and two semicircles.
We find the area of the rectangle using the formula;
We find the area of one of the semicircles and multiply by 2;
The area of the semicircles
We substitute and to obtain;
The area of the figure is
To the nearest tenth we have;
The correct answer is A
Answer:
A. 15 mi/h; 20 mi/hr
Step-by-step explanation:
Every time that she stopped, the value of the speed is 0, the speed limit is the maximum represented in the graph and when she travels at this speed for a while the graph is a horizontal line.
So she starts at 0, then increases her speed until a limit then she drives at this speed for a while which is represented by a horizontal line. then, she has to slow to a stop, which means she goes back to 0, later increases her speed until the limit, drives a while until she finds a stop sign, represented by a horizontal line, and then goes to 0.
In conclusion, the graph that represents the journy is the fourth graph.
