Answer:
.4625
Step-by-step explanation:
To find the mean, add up all the numbers, then divide by the number of terms
(0.2 +0.4+ 1+ 0.25) /4
1.85/4
.4625
see screenshot
general formula is
r² = (x - x-center)² + (y - y-center)²
note that I choose a radius of 6 arbitrarily. you didn't provide the information about the radius, but just put in yours
Answer:
x = 20
Step-by-step explanation:
4x and 5x are same- side interior angles and sum to 180° , then
4x + 5x = 180
9x = 180 ( divide both sides by 9 )
x = 20
Answer:
, domain: all real numbers
Step-by-step explanation:
The two functions that we have in this problem are:

and

Here we have to calculate
(f+g)(x)
Which is equivalent to:

Taking the two functions and substituting into this expression, we find:

We also have to find the domain of the new function. However, we notice that there are no restrictions on the value of x, since this is a second-order function with no denominators, logarithms or roots: therefore, the domain is all real numbers.
