Question

Calc AB! Please show work, the answers are provided. I need all work for part A AND B!!!

Answer 1

Step-by-step explanation:

24. A

B' ( t ) = 10 [ 20 CDS ( t/10) ] = 2 COS ( t/10 )

B' ( 7 ) = 1.5

After 7 days the number of beds in use is increasing at the rate of 1 1/2 beds per day.

24.B

2 COS ( t/10) =0

using calculator t = 15.7

B (12) = 20 Sin (1.2) + 50 = 68.6 = 69

B (15.7) = 20 Sin (1.57) + 50 = 70

B (20) = 20 SIn (20) + 50 = 68.25 = 68

Maximum number of beds in use occurs in afternoon of 15th day and is 70 beds.

I hope that helps and I hope  it's right
