Answer:

Transpose -5 to the other side so it becomes 45 + 5 which is equal to 50. Therefore, the value of y is 50.

If VW≅VY, WX = s + 69, and XY = 4s, what is the value of s?

valina [46]

<h2>Answer:</h2>

The value of s is 23°

<h2>Step-by-step explanation:</h2><h3>Known :</h3>

VW = VY
WX = s + 69
XY = 4s

<h3>Asked :</h3>

s = ?

<h3>Solution :</h3>

Since VW line and VY line has the same length, so the WX line and XY line should also have the same length.

4s = s + 69

4s - s = 69

3s = 69

s = 23°

<h3>Conclusion :</h3>

The value of s is 23°

Choose the equation that correctly uses the Pythagorean Theorem for the given right<br> triangle.

Zina [86]

3.8^2 + 6.8^2 = x^2 because the Pythagorean theorem is a^2 + b^2 = c^2 which c is the longest side or c in this case

What transformations are needed to change the parent cosine function to y=3cos(10(x-pi))?

LUCKY_DIMON [66]

Answer:

The graph of $y=cos(x)$ is:

*Stretched vertically by a factor of 3

*Compressed horizontally by a factor $\frac{1}{10}$ .

*Moves horizontally $\pi$ units to the rigth

The transformation is:

$y=3f(10(x-\pi))$

Step-by-step explanation:

If the function $y=cf(h(x+b))$ represents the transformations made to the graph of $y= f(x)$ then, by definition:

If $0$ then the graph is compressed vertically by a factor c.

If $|c| > 1$ then the graph is stretched vertically by a factor c

If $c$ then the graph is reflected on the x axis.

If $b> 0$ The graph moves horizontally b units to the left

If $b$ The graph moves horizontally b units to the rigth

If $0$ the graph is stretched horizontally by a factor $\frac{1}{h}$

If $h> 1$ the graph is compressed horizontally by a factor $\frac{1}{h}$

In this problem we have the function $y=3cos(10(x-pi))$ and our parent function is $y = cos(x)$

The transformation is:

$y=3f(10(x-\pi))$

Then $c =3>1$ and $b =-\pi < 0$ and $h=10 > 1$

Therefore the graph of $y=cos(x)$ is:

Stretched vertically by a factor of 3.

Also as $h=10$ the graph is compressed horizontally by a factor $\frac{1}{10}$ .

Also, as $b =-\pi < 0$ The graph moves horizontally $\pi$ units to the rigth
