Answer:
Step-by-step explanation:
The number which divides any other numbers
Doubling the side-lengths will multiply the area by four.
Proof:
Let the side-lengths of the rectangle by x and y. Clearly, the area will be x*y=xy. The new rectangle will have side-lengths 2x and 2y, and thus area 2x*2y=4xy. 4xy/xy=4 - hence, the new rectangle has four times the area of the old one.
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
