Since the order matters, it's a permutation of 7 letters, but mind you in 
MOROCCO. you have 3 O's and 2 C's, Hence the arrangements are:

⁷P₇ /(3!2!) = 7!/(3!2!) = 5040/(3!2!) = 420 arrangements

Astronomers measure large distances in light-years. One light-year is the distance that light can travel in one year, or approxi
Semenov [28]

Answer:

Option B - =8.4672\times 10^{13}

Step-by-step explanation:

Given : Astronomers measure large distances in light-years. One light-year is the distance that light can travel in one year, or approximately 5,880,000,000,000 miles.Suppose a star is 14.4 light years from earth.

To find : In scientific notation, how many miles away a star is from earth?

Solution :

One light-year is the distance that light can travel in one year is = 5,880,000,000,000 miles.

In scientific notation, 5.88\times 10^{12} miles.

In 14.4 lights year the distance is  =14.4\times5.88\times 10^{12}

In 14.4 lights year the distance is  =84.672\times 10^{12}

                                                  or  =8.4672\times 10^{13}

Therefore, Option B is correct.

What does it mean if the x-coordinate in an ordered pair is zero? What if the y-coordinate is zero? Both? Explain.
Harman [31]
If the x-axis ordered pair is (0,0) and the y-axis ordered pair is (0,0), it is just where the lines intersect or also known as the origin. Both x and y can have a (0) in it.

for example let's say that you have an ordered pair on the X-axis of (5,0) and a ordered pair on the y-axis of (-3,0) it would look like that^^

or if it was just (0,0) it would be a dot in the middle


Don't know if it helped much, but there ya go
