What is the final elevation if a butterfly starts at 20 m and changes negative 16 m
iVinArrow [24]

Answer:

4 meters

Step-by-step explanation:

Given that :

Initial elevation of butterfly = 20 meter

Change in elevation from initial height = negative 16 m = - 16 meter

Final elevation can be obtained by taking the sum of initial elevation and the change in elevation

(20 m + (- 16 m))

(20 m - 16 m)

= 4 meters

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.
