Find the amplitude of the function.
y=4 sin 3x

ANSWER

a. 4

EXPLANATION

The given function is

This function is of the form:

where the amplitude is |A|.

By comparison, A=4.

Therefore the amplitude is |4|=4

The correct choice is A.

a. 4

Step-by-step explanation:

Given the sine function in the form:

You can identify the amplitude, the period, the vertical shift and the horizontal shift:

For the function , identify "a":

Then the amplitude is:

hi there!

first we need to find out how much they are adding to each number to make the next number.

ex: 4 + 4 = 8, 8 + 8 = 16, and so on.

so continuing with 32,

32 + 32 = 64

64 + 64 = 128

128 + 128 = 256

256 + 256 = 512

4, 8, 16, 32, 64, 128, 256, 512

the 8th term of the sequence will be 512

let y equal to

the total fare and x is the mile of taxi ride. so the equation is

y = 0.55x + 1.75

since susie has

$10 to spend for a taxi cab, so he can have

10 = 0.55x +

1.75

x = 15 miles of

taxi ride

so the system of

inequality is

10 < 0.55x +

1.75

x > 2
