What are the amplitude, period, and phase shift of the given function?
Ft) = -4 sin (7t + 3)

Amplitude: 4

Period: 0.898 seconds.

Phase shift: 6.142 radians.

Explanation:

A sinusoidal function is defined by the following model:

(1)

Where:

- Amplitude.

- Angular frequency, measured in radians per second.

- Phase shift, measured in radians.

We need to transform the given function into this form by trigonometric means. The following trigonometric identity is used:

(2)

Then,

Then, the following information is found:

, ,

The period of the given function (), measured in seconds, is determined by the following formula:

(3)

Then, the following information is found:

Amplitude: 4

Period: 0.898 seconds.

Phase shift: 6.142 radians.

halibut, flounder, tuna, and trout are all fish. so your first answer is 1.) fish. and since fish is edible, your next answer would be 3). edible

to describe those fishes more thoroughly, some of those fishes live in fresh water, and some of the fishes live in salt water, and that is not a thing that they all have in common. the question is asking what is common with all of the fish, so answer choices 2). fresh water and 4). salt water are not right.

the words "strangest" and "unusual" suggest (:
