For a polygon inscribed in a circle, the circle passes through all of the vertices of the polygon.

The sphere also touches all of the vertices of the polyhedron, except this is done in 3 dimensions, not limited to just 2 dimension.

QUESTION POSTED AT 18/01/2020 - 01:07 AM

### A skier has decided that on each trip down a slope, she will do 3 more jumps than before. On her first trip she did 5 jumps. Derive the sigma notation that shows how many total jumps she attempts from her third trip down the hill through her tenth trip. Then solve for the number of total jumps from her third to tenth trips.

Since we are already given the amount of jumps from the first trial, and how much it should be increased by on each succeeding trial, we can already solve for the amount of jumps from the first through tenth trials. Starting from 5 and adding 3 each time, we get: 5 8 (11) 14 17 20 23 26 29 32, with 11 being the third trial.

Having been provided 2 different sigma notations, which I assume are choices to the question, we can substitute the initial value to see if it does match the result of the 3rd trial which we obtained by manual adding.

Let us try it below:

Sigma notation 1:

10
Σ (2i + 3)
i = 3

@ i = 3

2(3) + 3
12

The first sigma notation does not have the same result, so we move on to the next.

10
Σ (3i + 2)
i = 3

When i = 3; 3(3) + 2 = 11. (OK)

Since the 3rd trial is a match, we test it with the other values for the 4th through 10th trials.

When i = 4; 3(4) + 2 = 14. (OK)
When i = 5; 3(5) + 2 = 17. (OK)
When i = 6; 3(6) + 2 = 20. (OK)
When i = 7; 3(7) + 2 = 23. (OK)
When i = 8; 3(8) + 2 = 26. (OK)
When i = 9; 3(9) + 2 = 29. (OK)
When i = 10; 3(10) + 2 = 32. (OK)

Adding the results from her 3rd through 10th trials:
11 + 14 + 17 + 20 + 23 + 26 + 29 + 32 = 172.

Therefore, the total jumps she had made from her third to tenth trips is 172.

### What is 0.000000028 in scientific notation Step-by-step explanation:

In order to determine the answer, we have to know about scientific notation.

In general the scientific notation is: where:

a= rational number such that its absolute value has to satisfy: b= the power of 10 required so that the scientific notation is mathematically equivalent to the original number.

We have to follow the next steps to determine the scientific notation of any number:

• Move the decimal point in your number until there is only one non-zero digit to the left of the decimal point. The resulting decimal number is "a".
• Count how many places you moved the decimal point. This number is "b".
• If you moved the decimal to the left, "b" is positive. If you moved the decimal to the right, "b" is negative. If you did not need to move the decimal, "b" = 0.
• Remove trailing 0's only if they were originally to the left of the decimal point.

Finally, the number 0.000000028 written in scientific notation is:  ANSWERED AT 17/01/2020 - 02:02 AM
