Answers

Answer 1

Answer:

D cos (1/2 x )

Step-by-step explanation:

y = cos (x/2)

because from the graph x = 2pie

= cos pie = -1

Answer 2

The function whose graph is given by; cos (1/2 x )

What is graph?

A graph contains data of which input maps to which output.

Analysis of this leads to the relations which were used to make it.

For example, if the graph of a function is rising upwards after a certain value of x,  the function must be having increasingly output for inputs greater than that value of x.

If the function crosses x axis at some point, then for some polynomial functions, we have those as roots of the polynomial.

The function that we are given graphed has the point (0,1), this means whichever function f(x) it represents f(0) = 1.

Now, only the cosine function has the property that cos(π) = -1, thus

y = cos (x/2)

because from the graph x = 2π

The function whose graph is given by; cos (1/2 x )

describe all equation of motion​

Answers

Answer:

First equation

from definition of acceleration:

[tex]a = \frac{change \: in \: velocity}{time} \\ \\ a = \frac{v - u}{t} \\ \\ at = v - u\\ { \boxed{v = u + at}}[/tex]

Second equation

from displacement:

[tex]s = (average \: velocity) \times time \\ s = ( \frac{v + u}{2} ) \times t \\ \\ 2s = (v + u)t[/tex]

but v is u + at :

[tex]2s = \{(u + at) + u \} \times t \\ \\ 2s = (2u + at)t \\ 2s = 2ut + {at}^{2} \\ s = \frac{2ut}{2} + \frac{a {t}^{2} }{2} \\ \\ { \boxed{s = ut + \frac{1}{2} {at}^{2} }}[/tex]

third equation

from displacement:

[tex]s = ( \frac{v + u}{2} )( \frac{v - u}{a} ) \\ \\ 2as = (v + u)(v - u) \\ 2as = {v}^{2} - {u }^{2} \\ \\ { \boxed{ {v}^{2} = {u}^{2} + 2as }}[/tex]

s » displacement

v » final velocity

u » initial velocity
