A textbook company keeps track of its daily cost for printing whole textbooks to different schools, but can only print up to 500
seraphim [82]
Part A: Chose some value for x, that means any amount of books to print for example 100 books, so x=100
Replace x=100 in C(x) and solve:
C(100)=3.5*100+1200=1550
Part B: Replace C(x) by 1900 and solve for x from the given equation:
1900=3.5x+1200
3.5x=1900-1200
x=700/3.5= 200
Part C: the statement C(20)=1270 means that 1270 is the cost for printing 20 books.
Part E: C(40.5)=1341.75 I think this statement is incorrect given the context because x means number of books to print so this value must be an integer number.

How many numbers can you make with four digits
Natasha_Volkova [10]
Well, first consider how many digits there are. You have 1, 2, 3, 4, 5, 6, 7, 8, 9, and 0, depending on how you use it, that are all digits.
If you count 0 as a digit other than a place holder (0000, 0001, etc.), you would end up with ten thousand (10,000) numbers with four digits, starting with 0000, and ending with 9999. If you count 0 as nothing other than a place holder (1000, 1001, etc.), you would have nine thousand (9,000) numbers with four digits, starting with 1000.
So, depending on how you view 0, you can make up to 10,000 different numbers that contain four digits.

Hi there!

First, scientific notation is when you take a number like 15,000 or 0.0015 and turn it into a number that is less than 10 and greater than 1. What you do to make it that is you move that decimal point over to the left or right as needed. So for example, 15,000 would be 1.5 × 10^{4} and 0.0015 is 1.5 × 10^{-3}.

So if one light year is 5.88 × 10^{12} mi. that is just the scientific notation for 5880000000000 mi.

So if you take 5880000000000 mi. and multiply it by 11 then you get 64680000000000

5880000000000 × 11 = 64680000000000 or 6.468 × 10^{13}

So the answer would be \boxed{64680000000000} or \boxed{6.468*10^{13} }
