X^2+y^2=1 yes or no relation represents a function or not

We are asked to decide if the expression:

x^2 + y^2 = 1 represents a function.

We recall that in order to have a function, we need for a given value of x to have a SINGLE value of y associated with it.

So in this case, when x is 0 for example, we have the following:

0^2 + y^2 = 1

then y^2 = 1

and we realize that there are TWO values of y whose square form gives 1 (one is 1 and the other -1) Therefore, this relationship is NOT a function, since for example when x = 0 there are TWO values of y to which that x is associated (y = 1 and y = -1).

So please select that this is NOT a function for your answer.

Bee humming birds weigh only 0.0056 ounces. They haev t eat half their body weight every day to survive. How much food does a be

Advocard [28]

Answer:

The Humming bee need to eat 0.0028 ounces of food each day.

Step-by-step explanation:

Given:

Weight of the humming bee = 0.0056 ounces

We need to find amount of food humming bee should eat each day to survive.

Solution:

Now given that:

They have to eat half their body weight every day to survive.

So we can say that;

Amount of food humming bee needs to eat is half of the weight of the humming bee.

framing in equation form we get;

Amount of food humming bee needs to eat = $\frac{1}{2}\times 0.0056 = 0.0028\ ounces$

Hence The Humming bee need to eat 0.0028 ounces of food each day.

Answer:

The length of side x is $x = \sqrt{6}$

Step-by-step explanation:

Pythagorean Theorem:

In a right triangle, with sides a and b, and hypothenuse h, we have that:

$a^2 + b^2 = h^2$

In this question:

The vertical line on the sides means that both are equal, that is, measuring x, so $a = b = x$ .

Hypothenuse is the square root of 12. So $h = \sqrt{12}$

$x^2 + x^2 = (\sqrt{12})^2$

$2x^2 = 12$

$x^2 = \frac{12}{2}$

$x^2 = 6$

$x = \sqrt{6}$

The length of side x is $x = \sqrt{6}$
