Hungry Harry is a giant ogre with an even bigger appetite. After Harry wakes up from hibernation, his daily hunger H(t)H(t)H, left parenthesis, t, right parenthesis (in \text{kg}kgstart text, k, g, end text of pigs) as a function of time ttt (in hours) can be modeled by a sinusoidal expression of the form a\cdot\cos(b\cdot t)+da⋅cos(b⋅t)+da, dot, cosine, left parenthesis, b, dot, t, right parenthesis, plus, d. When Harry wakes up at t=0t=0t, equals, 0, his hunger is at a maximum, and he desires 30 \text{ kg}30 kg30, start text, space, k, g, end text of pigs. Within 222 hours, his hunger subsides to its minimum, when he only desires 15 \text{ kg}15 kg15, start text, space, k, g, end text of pigs. Find H(t)H(t)H, left parenthesis, t, right parenthesis. \textit{t}tstart text, t, end text should be in radians.

Harry's  hunger is  

Step-by-step explanation:

From the question we are told

 The  hunger of harry is      

 The hunger of harry is  maximum at  t =  0  

 The hunger of harry is minimum at  t =  2 hours

 The mass of pig desires at maximum hunger is

 The mass of  pig desires at minimum hunger is  

Generally at maximum hunger we have

=>      

=>      

Now  at minimum hunger

Generally the  minimum value of  

So

  At minimum

=>                    

Generally from trigonometric rules

                   here  n =  0 , 1 , 2 , 3  

Now since we are considering the minimum  =  0  

   So  

=>        

So

=>              

So

=>    

Adding  

      =>    

From equation 1

=>    

So we can represent the harry hunger as  

the final amount you will pay is $68.04.

the tip is determined by the pre-tax amount, so we calculate the tip based on the original bill, not after we've added sales tax.

to find the tip:

we can divide 54.00 by 100 to get 1% of 54. then we multiply that by 18.

54 / 100 = .54

.54 x 18 = 9.72

tip = 9.72$

to find the tax:

we can divide 54.00 by 100 to get 1% of 54. then we can multiply that by 8 to get 8%.

54 / 100 = .54

.54 x 8 = 4.32

tax= 4.32

now we can add the tip and tax to the bill to get our total.

54 + 9.72 + 4.32 = 68.04

total: $68.04
