An open shape is made up of line segments. In this type of shape there is at least one line segment that is not connected to anything at one of its endpoints, so the shape is not a closed figure. So, I am going to provide four graphs for this problem.
1. Parable
This is given by the curve:

See figure 1.
2. Cubic function.
This function is given by:

see figure 2
3. Quartic function
This curve is given by:

see figure 3
4. Cosine functionThis function is given by this equation:

See figure 4.
All these curves are open shapes. So, we can find a new open shape as the sum of all these curves as follows:

See figure 5.
X is -2 I think if you’re solving for x if not 3^4 is 81
Answer:
5/2
Step-by-step explanation:
5/6 * 3
Reduce the numbers with the greatest common divisor which is 3 since it goes in to both 6 and 3
6/3=2
5/2
Answer:

Step-by-step explanation:
In training for an Olympic bike race, Ped Al Moore trained by riding 216 miles in 12 hours, for an average of 18 miles per hour.
Speed is inversely proportional to the time taken

speed is 18 miles per hour and distance is 216 miles

Let 's' be the speed and 't' be the different time


Replace distance by 216
