Answer:

x = -5 or x = 5 (-1)^(1/3) or x = -5 (-1)^(2/3)

Step-by-step explanation:

Solve for x:

x^3 = -125

Taking cube roots gives 5 (-1)^(1/3) times the third roots of unity:

Answer: x = -5 or x = 5 (-1)^(1/3) or x = -5 (-1)^(2/3)

Is sin(x) even or odd ? prove with examples ?

zloy xaker [14]

Answer:

$\text{sin}(x)$ is an odd function.

Step-by-step explanation:

We are asked to prove whether $\text{sin}(x)$ is even or odd.

We know that a function $f(x)$ is even if $f(x)=f(-x)$ and a function $f(x)$ is odd, when $f(-x)=-f(x)$ .

We also know that an even function is symmetric with respect to y-axis and an odd function is symmetric about the origin.

Upon looking at our attachment, we can see that $\text{sin}(x)$ is symmetric with respect to origin, therefore, $\text{sin}(x)$ is an odd function.

In the context of relationships between variables, increases in the values of one variable are accompanied by increases in the v

TiliK225 [7]

Answer: Directly proportional.

Step-by-step explanation:

The increase of one variable which causes the other variable to increase points to a directly proportional relationship between the two variables. Similarly, the decrease of one variable will cause a decrease in the other variable.

One variable can also be the constant multiple of the other. This means that if one changes, the other one will change in PROPORTION to it.
