Answer:

g(-x)=-55x-3x\\-g(x)=-55x-3x\\-g(-x)=55x+3x\\hence\\g(x)=-g(-x)\\g(-x)=-g(x)

Step-by-step explanation:

g(-x)=55(-x)+3(-x)=-55x-3x \\\\-g(x)=-[55x+3x]=-55x-3x=g(-x)\\\\-g(-x)=-[-55x-3x]=55x+3x=g(x)

The average of four different positive integers is 9. What is the greatest value for one of the integers?
saul85 [17]

From the given information; Let the unknown different positive integers be (a, b, c and d).

An integer is a set of element that are infinite and numeric in nature, these numbers do not contain fractions.

Suppose we make an assumption that (a) should be the greatest value of this integer.

Then, the other three positive integers (b, c and d) can be 1, 2 and 3 respectively in order to make (a) the greatest value of the integer.

Therefore, the average of this integers = 9

Mathematically;

\mathbf{\dfrac{(a+b+c+d)}{4} =9}

\mathbf{\dfrac{(a+1+2+3)}{4} =9}

\mathbf{\dfrac{(6+a)}{4} =9}

By cross multiplying;

6+a = 9 × 4

6+a = 36

a = 36 - 6

a = 30

Therefore, we can conclude that from the average of four positive integers which is equal to 9, the greatest value for one of the selected integers is equal to 30.

Find the length of side x in simplest radical form with a rational denominator.
zloy xaker [14]

Answer: 10

Step-by-step explanation:

a 30° - 60° - 90° triangle has a side ratio of 1:√3: 2, meaning the side length across from the 30° is 1, the side length across from 60° is √3, and the side length across from 90° is 2

if you multiple the 1 * 5 = 5 (the 5 side length in the diagram), then also multiple (5 * √3 = 5√3) and (2 * 5 = 10)

since you're looking for the hypotenuse (the length across the 90°), the answer would be 10 (2 * 5 = 10)

*this method can work for any 30° - 60° - 90° triangle

you can also use trig:

sin (30°) = \frac{5}{x} (now just solve for x)

x * sin (30°) = 5

x = \frac{5}{sin(30)}

x = \frac{5}{1/2} ( because sin (30°) = 1/2 )

x = 5 * \frac{2}{1} = 10

*either method works!
