Describe the transformation required to obtain the graph of the given function from the basic trigonometric graph.

mamaluj [8]

Answer:

Option c. Reflection across the x-axis and vertical stretch by a factor of 7

Step-by-step explanation:

If the graph of the function $y = cf(x)$ 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 a.

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

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

In this problem we have the function $y = -7secx$ and our paretn function is $y = secx$

therefore it is true that

$c = -7\\\\|-7|> 1\\\\-7$ .

Therefore the graph of $y = secx$ is stretched vertically by a factor of 7 and is reflected on the x-axis

Finally the answer is Option c

For your friend's birthday, you have 3 presents to wrap. Find the combined surface area of these 3 gifts so you know how much wr

omeli [17]

The answer is: 5,614 square inches.

The explanation is shown below:

1. The gift on the bottom is a rectangular prism. To calculate its surface area, you must apply the following formula:

$SA=2[(l)(w)+(l)(h)+(h)(w)]$

Where $l$ is the length (20 inches), $w$ is the width (42 inches) and $h$ is the heigth (16 inches).

2. Substitute values:

$SA1=2[(20in)(42in)+(20in)(16in)+(16in)(42in)]=3,664in^{2$

3. The surface area of the other gifts can be calculated with the formula for calculate the surface area of a cube:

$SA=6s^{2}$

Where $s$ is the side.

4. The surface area of the bigger cube is:

$SA2=6(15in^{2})=1,350in^{2}$

5. The surface area of the smaller cube is:

$SA3=6(10in^{2})=600in^{2}$

6. The total surface area (the combined surface area of the three gifts) is:

$SAt=SA1+SA2+SA3\\SAt=3,664in^{2}+1,350in^{2}+600in^{2}\\SAt=5,614in^{2}$
