Yes it is a linear function because there is a slope and a y-intercept. For every input there is an output

A right triangle has a hypotenuse length of 13 units. One leg has a length of 12 units. Which equation can be used to determine

viktelen [127]

a = √(13² - 12²) units

<h3>Further explanation</h3>

<u>Given:</u>

A right triangle has a hypotenuse length of 13 units.
One leg has a length of 12 units

<u>Question:</u>

Which equation can be used to determine the length of the other leg?

<u>The Process:</u>

We will solve a problem regarding right triangles. In the process, there is a relationship between the Pythagorean Theorem with Exponent and Square Root.

Let us find out the equation to determine the length of the other leg. Let the length of the leg as "a".

The Phytagorean Theorem:

$\boxed{ \ (leg)^2 + (leg)^2 = (hypotenuse)^2 \ }$

$\boxed{ \ a^2 + 12^2 = 13^2 \ }$

Subtract by 12² on both sides.

$\boxed{ \ a^2 = 13^2 - 12^2 \ }$

To take the square root on both sides.

So here's the equation that can be used to determine the length of the other leg: $\boxed{\boxed{ \ a = \sqrt{13^2 - 12^2} \ }}$

- - - - - - - - - -

Notes

If we continue working on the above, the results will be as follows:

$\boxed{ \ a = \sqrt{13^2 - 12^2} \ }$

$\boxed{ \ a = \sqrt{169 - 144} \ }$

$\boxed{ \ a = \sqrt{25} \ }$

Hence the length of the other leg equal to a = 5 cm.

Of course, we agree with the use of the right intuition, which is to remember Pythagorean Triples, i.e., $\boxed{ \ 5-12-13 \ }.$ This method is very convenient when working on multiple-choice tests in a limited amount of time.

What is the probability that a patient shows improvement

Alexeev081 [22]

Answer:

.3375

Explanation:

Total people who were given drug: 800

Total people who showed improvement: 270

Probability:

$\boxed{ \sf \dfrac{favorable \ outcomes }{total \ possible \ outcomes}}$

<em>insert values</em>

$\rightarrow \sf \dfrac{270}{800}$

<em>simplify</em>

<em /> $\rightarrow \sf \dfrac{27}{80}$

<em>in decimals</em>

$\rightarrow \sf 0.3375$

-<br> (<br> -<br> 7.4–1.1)–(2.1–8.1)

SashulF [63]

Answer:

0.3

Step-by-step explanation:

(7.4-1.1) - (2.1-8.1)

Lets start with (7.4-1.1)

Step 1:

(7.4-1.1) =6.3 (All you do is subtract 7.4-1.1 and it gives you 6.3)

Step 2: Lets do (2.1-8.1)

(2.1-8.1)= -6 (2.1 minus 8.1 gives you -6 because 2.1 is smaller than 8.1 so it will give you a negative)

Step 3: Subtract

6.3-6

So your answer would be 0.3

Hope that helped :)
