You add up all the snowfall through the years, then divide it by 10 because of there being 10 numbers.
Answer:
Step-by-step explanation:
A quadratic function has the formula ax² + bx + c
- To determine if a graph will be narrow or wide, the leading coefficient, a, will be the factor that determines this
- The greater the coefficient, the narrower the parabola
- The lesser the coefficient, the wider the parabola
Here all of the functions are in the form ax²
- In
, our "a" term is 
- In y = -2x², our "a" term is -2
- In y = -3x², our "a" term is -3
- In
, our "a" term is 
We can eliminate the two functions with the negative coefficients because they are much smaller than the two functions with the fractions as coefficients, and will therefore open much wider.
We can now compare the two remaining functions, and 
- Giving the two fractions common denominators would turn them into
and 
- The equation with the larger fraction will be the parabola that is the narrowest. In this case, it is the .
- Therefore, will have the narrowest graph
The decimal place to the right of the tenths place is the hundredths place. The digit in that place is 9.
When the digit to the right of the place you're rounding to is more than 4, you increase the digit in the rounding place by 1.
Here, we have the hundredths digit is 9, which is more than 4, so we increase the tenths digit by 1. The rounded number is
... 56.4

Another way to get there is to add 5 in the hundredths place (the place to the right of the one you're rounding to). When you do that, you get 56.448. Now, throw away all the digits to the right of the one you're rounding to. This leaves
... 56.4

The reason I show this last method is to deal with cases like rounding 56.978. By the first rule, you're increasing the digit 9 by 1, which might be confusing. (it requires a carry into the next digit, making 57.0.) If you add .05 to this number, you get 56.978 +.05 = 57.028. Now when you throw away the digits to the right of the tenths digit, you have 57.0.

Answer- 7n-6/2
Step by step explanation-
solution,
here
Given,
g(n)=2n+6/7
Let g(n) be y
So,
Interchanging the position of n and y we get the reverse So,
n = 2y+6/7
or, 7n = 2y+6
or, 7n-6 = 2y
or, 7n-6/2 = y
Therefore the inverse function of g(n) is 7n-6/2
Thank you.
