The answer is 7 3/4 inches.
I noticed the word "train" in the problem and I knew I had to help you! :)
There’s only one solution. Solution is the same as x or x intercepts so it would be one at (2,0)
Since the only places where an x-ordinate exist are the closed circles, the domain will simply be:
D: { -5, -4, -3, 1, 2, 5 }
It is (7x)
^(2/3). If we look at our exponent laws (SEE ATTACHMENT), we can see that we can express our equation as so.
Answer:
5.2 x 10^-2
Step-by-step explanation:
Scientific notation is used to simplify very large or very small numbers.
The formula for scientific notation is (a x 10^ n)
(a) is a number that is both greater than 1 and less than 10
(n) is the number of places the decimal place moves. This number can be positive or negative depending on the number you are converting. If the original number is greater than 1 (n) will be positive, and if the number is less than 1 (n) will be negative.
First you should write out the number.
0.052
Then, you should determine the number places the decimal point must move, and create a number greater than 1 and less than 10. (You should also pay attention to the direction the decimal point moves)
For this problem you will move the decimal place 2 places to the right to create the number 5.2.
Last, substitute the values into the formula. For this problem (a)= 5.2 and (n)= -2. This gives us the expression 5.2 x 10^-2.
