The process of writing repeating decimals or repeating pattern of digits by using a bar is called Bar NotationBar notation can be put with single or multi-digit repeating numbers or repeating patterns of decimals. For a single-digit repeating decimal, the repeating number is written once and a bar is put over it.

Rewrite 8.24 × 10'6 in standard notation. 8,240,000,000 824,000 8,240,000 82,400,000

Answer:

Option 3 - 8.24\times 10^6=8,240,000

Step-by-step explanation:

Given : Number - 8.24\times 10^6

To find : Re-write the number into standard notation?

Solution :                  

Standard notation in the expansion of scientific notation.

Scientific notation 8.24\times 10^6

10^6 means 10 with 6 zeros i.e. 1000000

So,  =8.24\times 1000000

Removing decimal,

=\frac{824}{100}\times 1000000

=824\times 10000

=8240000

Therefore,  8.24\times 10^6=8,240,000

So, Option 3 is correct.

Rewrite 105,000 in scientific notation. 1.5 × 10'3 1.05 × 10'5 1.5 × 10'4 1.05 × 10'3

Answer:

1.05* 10^{5}.

Step-by-step explanation:

Given  : 105,000

To find : Rewrite 105,000 in scientific notation.

Solution : We have given  105,000 .

Steps to write in scientific notation :

Step 1 : If a number has n digit we move decimal point ( n-1) place to left  and to balance , multiply by 10^{n-1}.

We can see there are n = 6 in 105,000

So, we move decimal point 5 place to the left .  

Then  1.05* 10^{5}.

Therefore,  1.05* 10^{5}.

Use the definition of a polygon inscribed in a circle to help you develop a definition for a polygon inscribed in a sphere.

For a polygon inscribed in a circle, the circle passes through all of the vertices of the polygon. Using this idea, a polyhedron (a 3-D polygon) inscribed in a sphere can be described in a similar way. The sphere also touches all of the vertices of the polyhedron, except this is done in 3 dimensions, not limited to just 2 dimension.

Consider the function represented by the equation 6c = 2p – 10. Write the equation in function notation, where c is the independent variable.

we have

 6c = 2p - 10

If c is the independent variable

then

p is the dependent variable

so

clear variable p

 6c = 2p - 10

Divide by  2 both sides

 3c = p - 5

Adds  5 both sides

 3c+5 = p - 5 +5

 p=3c+5

Write the equation in function notation

 f(c)=3c+5

therefore

the answer is

the equation in function notation is equal to  f(c)=3c+5

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.

QUESTION POSTED AT 17/01/2020 - 02:10 AM

What is 0.000000028 in scientific notation

Answer:

The answer is:

0.000000028=2.8*10^-^8

Step-by-step explanation:

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

In general the scientific notation is:

a*10^b

where:

a= rational number such that its absolute value has to satisfy:

1\leq |a|<10

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:

a=2.8\\b=-8\\\\a*10^b=2.8*10^-^8

0.000000028=2.8*10^-^8
