The function, f(t)= 1.2 cos 0.5t, does not have an amplitude and has a period of 4π.

False

Step-by-step explanation:

Given in the question a function,

f(t)=1.2cos0.5t

Standard form of cosine function is

f(t)=acos(bt)

Amplitude is given by = |a|

Period of function is given by = 2π/b

So the amplitude is |1.2| = 1.2

    the period is 2π/0.5 = 4π

False

Step-by-step explanation:

The given function is

This function is of the form:

where A=1.2 and B=0.5

The amplitude of this function is given by;

|A|=|1.2|=1.2

The period of this function is given by;

The correct answer is False

step-by-step explanation:

consider an orange peel: if you want to try and lay it flat, you have to stretch it, we know exactly how things are being stretched or squashed at any given point. we have many different map projections because each has different patterns of some projections can even preserve certain features of the earth without

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2
