Step-by-step explanation:
Answer:
About 11.299 hours.
Step-by-step explanation:
To solve this problem, you can set up an equation to model the decay of the medicine. Let's call the time that medicine has been in the body x.
Taking the log x of both sides, you get
hours. Hope this helps!
The piecewise function all the way to the left (x + 3) should have an ending point shaded in. [At x = -2] The next function ((x^2) -1) should have both ending points left unshaded. Finally, the logarithm function should have a shaded in starting point [At x = 1] and should have an unshaded ending point at x = 3.
Let the no. of girls be x and boys be y......
x/y=1/3
=>3x=y ...............(I)
now 4 boys leave the class is then
x/y-4=2/5
=>5x=2y-8
(I)=>5x=2(3x)-8
x=8
now 3x=y
=>y=24
therefore no. of girls is 8 and the no. of boy is 24..............
I have tried my best.....hope i helped............
