Answer:
9 out of 12 is 75%
Step-by-step explanation:
you would divide 9 by 12, and your answer would be:
1) 0.75 for decimal form
2) 75% for percentage
3) 3/4 for fraction
I'm not positive but I think that it is.

Answer:
y = 18·8^x
Step-by-step explanation:
We assume you want a model that looks like y = ab^x.
To find the values of "a" and "b", you can fill in the given numbers and solve the system of equations:
18 = a·b^0
9216 = a·b^3
The first equation tells you ...
18 = a
Dividing the second equation by the first gives ...
9216/18 = (a·b^3)/(a·b^0) = b^3
512^(1/3) = b = 8
The exponential function is ...
y = 18·8^x
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
