Answer:
the first one should be 5.28x10^-2 and the second one should be 3.2x10^6
Step-by-step explanation:
because with 0.0528 you move the decimal right twice. which makes it negative.
with 3,200,000 you assume that the decimal is at the end and move it between the three and the two. making it have 6 moves. since it moves left its positive
Answer:
0.0528=5.28*10^-2
Step-by-step explanation:
Scientific notation is a simpler way to write very large or very small numbers. In this case, you want to write a small number in simpler form. To write in scientific notation, the number being multiplied always has to be between 1 and 10. Here, it is 5.28, so we aren't breaking the rule. You can see that we moved the decimal two places to the right, which is going to make the exponent negative (the opposite applies for larger numbers). To convert to scientific notation, move the decimal place to the right or left until you get a number between 1 and 10. Then, if you moved to the right, multiply the number that is between 1 and 10 by 10 the the negative [# of spaces that you moved the decimal] power. If you moved it left, do the same but a positive exponent. To convert from scientific notation, write the number that is being multipied by 10 on a sheet of paper. if the exponent is negative, you'll have to move the decimal left for every number that the exponent is. For example, if the exponent was -5, you would move the decimal to the left 5 times. If it was just 5, you would move the decimal to the right 5 times. Then, there's your number.

if you reflect any shape across the x-axis and then rotate it 90 degrees clockwise about the origin, do you get the same results as if you reflect it across the y-axis and then rotate it 90 degress counterclockwise about the origin? what does this mean?
Yes, a shape can be reflected across the x-axis and then rotated 90 degrees in a clockwise direction around the origin to achieve the same results as a shape reflected across the y-axis and rotated in a counterclockwise direction. This implies that these two transformational sequences are similar.
What is reflection in Mathematics?A reflection is referred to as a flip in geometry. A reflection is the shape's mirror image. A line, called the line of reflection, will allow an image to reflect through it. Every point in a figure is said to reflect the other figure when they are all equally spaced apart from one another.

Which graph represents y as a function of x ?
Answer:
The second one
Step-by-step explanation:
Simply put, in order to be a function the x can not repeat and that is the only graph where they x does not repeat.
Second one graph is represents y as a function of x.
Here four graph shown.
We have to check which graph shows y as a function of x.
What is function?
If for each value of x, there is only one possible value of y or As a graph, if we trace a vertical line; it cannot cross more than one point of the function; then it is called function.
To solve this question we use the definition of function,
In first graph, when we draw vertical line then it intercepts on graph in more than one point, so it does not represents y as a function of x
Similarly, in third and fourth graph we use vertical line test.
Hence, only in second one graph, the vertical line test will be fulfill.
So, Second one graph is represents y as a function of x.

Three salesmen working for the same company, selling the same product. And, although they are all paid on a weekly basis, each salesman earns his paycheck differently. Salesman A works strictly on commission. He earns $65 per sale, with a maximum weekly commission of $1,300. Salesman B earns a weekly base salary of $300, plus a commission of $40 per sale. There are no limits on the amount of commission he can earn. Salesman C does not earn any commission. His weekly salary is $900. The following table shows the number of sales each salesman had during the first three weeks of this month
1 2 3
Salesman A 11 14 16
Salesman B 14 15 13
Salesman C 16 12 11

2. 8.4 X 2.3 X 2.09 = 40.3788
3. $10.04 - $13.47
4. Your friend would be incorrect because their decimal is in the wrong place. Take the decimals out of it and think about it. Can 1 times 2 equal anything near 31? no, so it's not reasonable that your friend could multiply 1.2 X 2.6 and get anything near 31.2
5. It is more reasonable to say between 5 and 6 because even when you round both of the numbers up (3 X 2), you still only get 6.
