Answer:

You can make one triangle with these lengths

Step-by-step explanation:

we know that

The <u>Triangle Inequality Theorem</u> states that the sum of any 2 sides of a triangle must be greater than the measure of the third side

Verify if the lengths satisfy the triangle inequality theorem

1) 2+1 > 2

3 > 2 ------> is true

2)2+2 > 1

4 > 1 -----> is true

The lengths satisfy the triangle inequality theorem

therefore

You can make one triangle with these lengths

Some periodic motions, also known as armonic motions, with which much of us are familiar with are:

- The motion of the swinger when a kid is balancing forward and backward

- The motion of a pendulum

- The motion of the needles of a watch.

- The motion of a satelite around a planet.

- The spinning of the wheel of a stationary bycicle.

- A rocking chair

All the motions in which the object passes once and other times through the same point are periodic motions.

Both scientists and businesses are interested in tracking periodic motions using equations because they appear in many situations in nature and in daily life. The cycles are examples of periodic motion. By tracking this type of motion you can make models that permit you to explain the phenomena and predict cycles. This is predict facts that repeast with a certain period.

Find the value of x. If necessary, write your answer in simplest radical form.<br> x=?

Pythagoras’ theorem

a^2 + b^2 = c^2

Where a and b are two sides on a triangle and c is the hypotenuse.

Rearrange to find one to the sides that isn’t the hypotenuse.

a^2 = c^2 - b^2
a^2 = 25^2 - 10^2
a^2 = 625 - 100
a^2 = 525

(square root)

a = √525

= 5√21

need this answered asap Which function has a minimum and is transformed to the right and down from the parent function, f(x) = x

torisob [31]

The function that has a minimum and is transformed to the right and down from the parent function is; g(x) = 8(x² - 3²) - 5

<h3>How to Interpret Functions?</h3>

By inspection, only Functions B) and D) have a minimum.

For the first function in option B, we have:

g(x) = 4(x²- 6x + 9) + 1

This can be simplified to;

g(x) = 4( x - 3 )² + 1

Thus, we can say that this first function is transformed to the right and up from the parent function.

For the second function in option D, we have;

g(x) = 8(x² - 6x + 9 ) - 5

The function can be simplified to get;

g(x) = 8( x - 3 )² - 5

Thus, we can say that it is transformed to the right and down.

The function that has a minimum and is transformed to the right and down from the parent function is D
