Step-by-step explanation:

√((1 + sin x) / (1 − sin x)) + √((1 − sin x) / (1 + sin x))

Square and take the square root.

√[√((1 + sin x) / (1 − sin x)) + √((1 − sin x) / (1 + sin x))]²

√[(1 + sin x) / (1 − sin x) + 2 + (1 − sin x) / (1 + sin x)]

Add the fractions using least common denominator.

√[((1 + sin x)² + (1 − sin x)²) / (1 − sin²x) + 2]

√[(1 + 2 sin x + sin²x + 1 − 2 sin x + sin²x) / (1 − sin²x) + 2]

√[(2 + 2 sin²x) / (1 − sin²x) + 2]

Use Pythagorean identity:

√[(2 + 2 sin²x) / (cos²x) + 2]

√[2 sec²x + 2 tan²x + 2]

√[2 sec²x + 2 (tan²x + 1)]

Use Pythagorean identity:

√[2 sec²x + 2 sec²x]

√[4 sec²x]

±2 sec x

If x is in the second quadrant, then sec x < 0.

-2 sec x

Answer:

B

Step-by-step explanation:

The graph of x² is known as the parent function. From it, all quadratics can be transformed to make their graphs. It can undergo a series of transformations like translations up/down/left/right or stretch and compression vertically and horizontally. Usually the equation can tell you you what transformations it undergoes. Since g(x) is the same equation as x² except for 4/5 this is a vertical compression. Since it is the leading coefficient under multiplication and 4/5 < 1, this is a compression vertically. Answer B is correct.

What are the coordinates of the vertex of the graph of the absolute value function h(x) = 3|x + 5| + 2? A) (5,-2) B) (-5,2) C) (
saw5 [17]

Answer:

B) Vertex = (-5, 2)

Step-by-step explanation:

Vertex can be defined as defined as the point where two lines meet and form a particular angle with each other. It can also be described as the point where a line changes its direction

We can find vertex by two methods:

<h3>1) GRAPH</h3>

We can see in the graph attached below that the line changes its direction at point (-5, 2). So the vertex is (-5,2)

<h3>2) FORMULA</h3>

General form of equation of mod function is given by

y = a |x - h| + k

where Vertex = (h, k)

The given equation is

h(x) = 3 |x + 5| + 2

h(x) = 3 |x - (-5)| + 2

where h = -5 and k = 2

So the vertex is:

Vertex = (-5, 2)

Help me please I dont know what to do
gtnhenbr [62]

Answer:

It's <u>option A. ± </u>√6<u>0</u>

Step-by-step explanation:

x^2  = 60

here ^2 will move to the other side and when it does it'll become a square root to 60.

so, x = √60

now, the answer in its simplified form would be 2√15 and -2√15.

The answer of this square root will be negative as well as positive, so, ±√60.
