Answer:
Step-by-step explanation:
1. 3.8 x 10^5 + 5.5 x 10^5 = 930,000 or 9.3 x 10^5
You just have to solve the equation and shorten the answer. For number one the answer is 930,000, so you have to make it into a number with decimals since a scientific notation number can not be equal to 10 or be greater. So you have to round the number to 9.3 not 93. To "round" it to 9.3 you have to move the decimal at the end of 930,000 to be in between the numbers 9 and 3. How many times you move the decimal to the left or right, that is the exponent of 10. So for 930,000 you moved the decimal 5 times to the left so the exponent for 10 is positive 5.

Answer:
The Inverse variation states a relationship between the two variable in which the product is constant.
i.e 
then the equation is of the form: 
where k is the constant of variation.
As per the given information: It is given that x and y vary inversely and that y = 1/6 when x = 3.
then, by definition of inverse variation;
xy = k ......[1]
Substitute the given values we have;
Now, find the value of y when x = 10.
Substitute the given values of x=10 and k = 1/2, in [1] we have;
Divide both sides by 10 we get;
therefore, a function that models the inverse variation is; 
and value of when x = 10.
