S = 899
s = 3w - 66

3w - 66 = 899
3w = 899 + 66
3w = 965
w = 965/3
w = 321.67 <==

Ok well first of all let's calculate how many cartons there are of each size:

There are 264 cartons in total and 1/6 of these are small, 2/3 are medium and the rest are large, thus:
Number of small cartons = (1/6)*264 = 44
Number of medium cartons = (2/3)*264 = 176
Number of large cartons = 264 - (44 + 176)
= 264 - 220
= 44

Now we can calculate how many eggs are needed to fill each type of carton:

Each small carton holds 8 eggs, thus the number of eggs needed equals:
8*44 = 352 eggs
Each medium carton holds 12 eggs, thus the number of eggs needed equals:
12*176 = 2112 eggs
Each large carton holds 18 eggs, thus the number of eggs needed equals:
18*44 = 792 eggs

Thus the total number of eggs needed = 352 + 2112 + 792 = 3256

Find dy/dx and d2y/dx2, and find the slope and concavity (if possible) at the given value of the parameter. (If an answer does n
ella [17]

Answer:

The slope of the function is  ²/₃ and since the second derivative is zero, the concavity doesn't exist.

Step-by-step explanation:

Given;

x = 6t

y = 4t - 3

point t = 4

\frac{dy}{dx} = (\frac{dy}{dt} )/(\frac{dx}{dt} )=\frac{\frac{dy}{dt} }{\frac{dx}{dt}} \\\\\frac{dy}{dt}  = 4; \frac{dx}{dt} = 6\\\\\frac{dy}{dx} =\frac{4}{6} = \frac{2}{3}

The slope of the function is  ²/₃

take the second derivative of the function;

the second derivative will be zero since the first derivative is a constant value.

\frac{d^2y}{dx^2} = 0

Since the second derivative is zero, the concavity doesn't exist.
