Answer:

46.7°

Step-by-step explanation:

The mnemonic SOH CAH TOA is intended to help you remember the relationships between sides and angles in a right triangle.

Here, the side lengths given are the hypotenuse (11) and the side opposite the angle (8). The mnemonic reminds you the relation involving those sides is ...

Sin = Opposite/Hypotenuse

Applying this to the given triangle, you have ...

sin(x) = 8/11

<h3>Angle</h3>

The angle is found using the inverse sine function. This may be called the sin⁻¹ function on your calculator. It is also referred to as the arcsine function.

x = arcsin(8/11) ≈ 46.658°

x ≈ 46.7°

<em>Additional comment</em>

The attachment shows a calculator making this computation. The angle mode is set to "Degrees", as indicated in the lower left corner.

Two exponential functions, fand g, are shown in the figure below, where g is a transformation of f.

JulijaS [17]

Answer:

A.) g (x) = f (x) - 2

Step-by-step explanation:

The first thing we are going to do in this case is to take into account the following definition.

Translations are transformations that change the position of the graph of a function.

The general shape of the graph of a function is moved up, down, to the right or to the left.

The translations are considered rigid transformations. Now we will see how these are performed.

Vertical translations:

Suppose that k> 0

To graph y = f (x) + k, move the graph of k units up.

To graph y = f (x) -k, move the graph of k units down.

Using the definition we conclude that:

g (x) = f (x) - 4

The next model of a sports car will cost 12.2% less than the current model. The current model costs $34,000 . How much will the

Kryger [21]

Answer:

Price decrease in dollars = $4,148
Price of next model = $29,852

Step-by-step explanation:

The next car will be 12.2% cheaper. This amount in dollars is:

= Percentage decrease * Current model price

= 12.2% * 34,000

= $4,148

The price of the next model will therefore be:

= 34,000 - 4,148

= $29,852
