What is the sum of all real numbers x that are not in the domain of the function f(x) = \frac{1}{x^2-7} + \frac{1}{x^3-8} + \frac{1}{x^4-9}~?

The sum of all real numbers x that are not in the domain of the function f(x) is 2.

Step-by-step explanation:

The given function is

The domain is the set of inputs. So, the domain of the given function is all real numbers except those numbers for which denominator values is equal to 0.

It means is not included in domain.

It means 2 is not included in domain.

It means is not included in domain.

The sum of all real numbers x that are not in the domain of the function f(x) is

Therefore the sum of all real numbers x that are not in the domain of the function f(x) is 2.

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.

it would be 6xy and -16xy.
