Answer:

y² = x² - z²

Step-by-step explanation:

x² - y² = z²

Transpose y the other side

x² - z² = y²

or

y² = x² - z²

Answer:

y= ± \sqrt{x^2-z^2}

Step-by-step explanation:

Given

x² - y² = z² ( isolate y² by subtracting x² from both sides )

-y² = z² - x² ( multiply through by - 1 )

y² = x² - z² ( take the square root of both sides )

y = ± \sqrt{x^2-z^2}

What is the length of the hypotenuse of a right triangle if each of the two legs is 7 units?
Katyanochek1 [597]

To find the hypotenuse of a right triangle you can use the Pythagorean theorem. (a² + b² = c²) Using the measurements provided we can solve like this.


Both a² & b² = 7²


7 x 7 = 49


49 + 49 = 98


Now we need to find the square root of 98 (c²) to get our answer.


9.9 x 9.9 = 98.01 or about 98


The measurements for the tirangle are 7 units, 7 units, and 9.9 units.


Hope this helps!

Davis Electronics manufactures a certain type of radio that requires 18 working resistors per radio. If one out of 22 resistors
REY [17]

Since One Radio in Davis Electronics requires 18 working resistors, then 2,145 radios will require 18\times2145=38610 resistors.

Now we know that one out of 22 resistors is defective. This means that the number of non defective or perfect resistors in a set of 22 resistors is 21.

So, obviously, if we pick a set of 40,370 resistors then the set of working resistors we will get is 40370\times \frac{21}{22} =38535.

As can be clearly seen from the above calculations the required amount of working resistors is 38610 and the amount of working calculators available to us is 38535.

Thus, since the required amount of working resistors is greater than the amount of working resistors available, 40,370 resistors are not enough to assemble 2,145 radios.

Answer if you only know
salantis [7]
⇒ Based on the given rules of "Fire-Water-Sponge," outcomes 1<span>, </span>5<span>, and </span>8 are outcomes where you lose.

<span>Therefore, </span><span>1,5, and 8</span><span> are the subset of outcomes where you lose, and we now can say that the statements "The subset consists of all of the outcomes where your friend wins" and "The subset consists of all of the outcomes where you do not win, and there is not a tie" accurately describe the subset.

</span>
Furthermore, because every subset outcome involves you losing, the statements "The subset consists of all of the outcomes where you win" and "The subset consists of all of the outcomes where there is a tie" do not accurately describe the subset.


\star The statements that accurately describe the given subset of the sample space are:

\star <span>The subset consists of all of the outcomes where your friend wins.

</span><span>\star </span>The subset consists of all of the outcomes where you do not win and there is not a tie.
