Answer:

The function is defined as H (t) = 4 cos (2π/5 ( t - 1.5)) + 8

Step-by-step explanation:

Solution

Let the function be a cosine function

H(t) a cos(b(t+c)) + d

Now,

The maximum height,is H max =12

The minimum height , is H min = 4

The amplitude, a is denoted by :

a= H max - H min/2

= 12 - 4/2 = 8/2 = 4

Thus,

The vertical shift , d is given by:

d = H max + H min/2

= 12 + 4 /2 = 16/2 = 8

The period T is given by,

T=6.5-1.5=5

So,

b is given by ,

b= 2π /T = 2π/5

The phase shift , c is given by :

since maximum height occur at 1.5 we get, c=-1.5

Therefore, our function is defined as:

H (t) = 4 cos (2π/5 ( t - 1.5)) + 8

Given:

A circle with diameter 9 cm.

To find:

The area of the circle.

Solution:

The area of a circle is:

$A=\pi r^2$ ...(i)

Where r is the radius.

We know that, the diameter of a circle is twice than its radius.

The diameter of the given circle is 9 cm.

$r=\dfrac{9}{2}$

$r=4.5$

Substituting $r=4.5, \pi =3.14$ in (i), we get

$A=(3.14)(4.5)^2$

$A=(3.14)(20.25)$

$A=63.585$

$A\approx 63.6$

Therefore, the area of the given circle is 63.6.
