Answer:
Step-by-step explanation:
To calculate the distance between the star that is 13.4 light years away from the earth, you just have to multiply 13.4 by 5,880,000,000,000, which is how many miles there are in a light year.
So you´d get:
To convert this into scientific notation, you just have to count how many numbers are there after the first numeric value, in this case how many numbers are there after the first seven.
There are 13 numbers after the first seven now you just add a decimal point after the seven and add a , the X is the number of numeric values after the decimal point, since in this case there are 13 numeric values after the decimal point we added, we just add the 13 instead of the X:
And the number in scientific notation would be:

Answer:
the multiplicity is 4
Step-by-step explanation:
The graph shows a root at x = -2 that has a multiplicity of 2. You know the multiplicity is even, because the graph does not cross the x-axis. The multiplicity is 2 because the general shape of the graph in that area matches that of a quadratic (parabola).
The multiplicity of the root at x=4 is also an even number, because the x-axis is not crossed. However, the graph is significantly flatter at that point (than at x=-2), meaning the multiplicity is greater than 2. It is at least 4.
When we draw a graph with a multiplicity of 6 at x=4, we find the ratio of the peaks near x=-4 and x=0 to be different from that shown here. The suggests that the multiplicity of the root at x=4 is exactly 4.
