Question

What is the rate of change from x = π to x = 3 pi over 2?

Answer 1

what is the y values?

Answer 2

they didnt give them

Answer 3

\[x = \pi\]
then a change happens,which results in:

\[x = \frac{ 3 \times \pi }{2 }\]

The rate of change =

First guess:

\[\frac{ 3 \times \pi }{2 / \pi}\]

\[= \frac{ 3 \times \pi }{ 2} \times \frac{ 1 }{ \pi }\ = \frac{ 3 }{ 2 }\]

If in percentage then:

\[\frac{ 3 }{ 2 } \times 100 = 150 % \]

there's a increase of about 150% !

or if using delta summation:

\[\pi - \frac{ 3 \times \pi }{2 } = 2\pi - 3\pi /2 = -\pi/2\]

=\[= \frac{ -\pi }{2 } \div \pi / 1\]
=\[-1 / 2\]


@silver123:is this is so?..they haven't provided the value for y ..all these are my guess

Answer 4

cool, thanks

Answer 5

is the guesses are correct or not? is they comply with the rules?

Answer 6

oh the choices were :
a. - pi/6
b. - 6/pi
c. pi/6
d. 6/pi

Answer 7

then how it's cool ...all is result is wrong..any guess by you or correction

Answer 8

i really have no idea...
