Answer:
1.5 miles per hour
Step-by-step explanation:
3 miles divided by 2 hours
y=0
................your welcome
Differentiate with respect to x and y
2x +10 y y' = 0
get y' alone
y' = -2x/(10 y)
reduce
y'=-x/(5y)
continue with quotient rule of differentiation
y'' = ( 5y(-1) - (-x) (5y')) / (5y) squared
y'' = (-5y + 5xy') / (25y squared)
reduce by dividing each term by 5
y" = (-y +xy') / (5y squared) answer
Now if the teacher wants you to continue so no y or y' shows
substitute y' = -x/(5y) and y = square root ((5-x squared) / 5)
and simplify
Answer:
or 1.96875oz
Step-by-step explanation:
You can solve this problem by setting up a ratio. The first step is to convert the dosage into decimal form. 3/4oz=0.75oz. Now, you know that for a 24 pound child, you need 0.75oz of medicine. 24:0.75=63:x, which can be turned into the fractions 
. Multiplying both sides by x and dividing both sides by 
, you get x=1.96875, or . Hope this helps!
I don't think I know how to completely help you with this question, but I can help get you started. Basically, A=432 W=3/4L L=X (because that's the variable that you're trying to find.) So, overall the setup would be: 3/4X=432
I hope this helps cx
