Answer:

Step-by-step explanation:

First, multiply straight across and put everything together:

$\frac{3a}{b}\cdot \frac{b^2}{12c}=\frac{3ab^2}{12cb}$

Notice we can simplify by cancelling a b and reducing 3/12:

$=\frac{ab}{4c}$

This cannot be simplified further.

Amplitude:

we can see that

maximum value is 3

minimum value is -1

so,

$A=\frac{max-min}{2}$

$A=\frac{3+1}{2}$

$A=2$

Period:

It is time completed after which value repeats itself

so, we get

$T=\pi -0$

$T=\pi$

so,

10.) For the natural logarithm function, determine the point on the curve where its associated tangent line passes through the

Lunna [17]

f(x)=lnx

y=f(x)

dy/dx= 1/x

tangent at (x,y) has slope 1/x

eqn of tangent is y = mx + c

since the tangent passes through origin, c=0

substitute y = lnx and m= 1/x to above eqn

lnx = 1

x=e

y=lne=1
