Answer:
B
Step-by-step explanation:
The scientific notation is symbol or the shorten way to rewrite the number that is too small or too large to write the full number. The scientific notation of a number has the form as the formula below:
<em>c x 10^n </em>
Based on this formula, it can be seen that answer C and D are not the correct answer.
Furthermore, in this formula, <em>c </em>can be any number ranging from 1 to 10 but not including 10 and <em>n </em>has to be an integer number.
So that in answer A, <em>c = 56 > 10 </em><em>is inappropriate.</em>
In answer B, <em>1< c = 5.6 < 10</em> and <em>n = 6 </em>
=> B is the correct answer
Really
just calculate the slope
slope is (y2-y1)/(x2-x1)
for x=0, y=1
for x=1, y=3
slope=(y1-y1)/(x-x1)=(3-1)/(1-0)=2/1=2
answer is 2
3.9 is your answer hope it helps
You multiply the area by the scale factor twice. Here is an example: if we have a rectangle that has a length 3 and a height of 4 and the scale drawing with a scale factor of 2, how many times bigger is the scale drawings area? The original shape is 3 by 4 so we multiply those to find the area of 12 square units.
