Write 7,520,000,000,000 in scientific notation. a. 75.02 × 1012 b. 7.52 × 10–12 c. 7.52 × 1012 d. 0.752 × 1013

The correct answer is C) 7.52 x 10^12

Step-by-step explanation:

To find any number in scientific notation, you have to move the decimal place until the number is in between 1 and 10. Then, count the amount of places that it moves and use that as the exponent. If it moves to the left it is positive. If it moves to the right it's negative.

So, since we move this to the left 12 times, then we make it positive 12.

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
