A commuter airline makes lattes in the galley and sells them to passengers. A regular latte contains a shot of espresso, 1 cup o
Alik [6]

Answer:

To maximize profit, the amount of each type of coffees made are;

The number of regular latte made = 52 cups

The number of low-fat latte made = 48 cups

Step-by-step explanation:

The given parameters are;

The number of espresso in a regular latte = 1 shot

The number of cups of 2% milk in regular latte = 1 cup

The amount of whipped cream in a regular latte = 0.5 cup

The number of cups of skim milk in the low-fat latte = 1.25 cup

The number of espresso in a low-fat latte = 1 shot

The amount of whipped cream in a low-fat latte = 0 cup

The number of cups of espresso in the journey = 100 shots

The number of cups of skim milk in the journey = 60 cups

The number of cups of 2% milk in the journey = 60 cups

The amount of profit the airline makes on each regular latte = $1.58

The amount of profit the airline makes on each low-fat latte = $1.65

Let 'x' represent the number regular lattes made and let 'y' represent the number low-fat lattes made, we have;

x ≤ 30/0.5 = 60

x ≤ 60

y ≤ 60

y ≤ 60/1.25 = 48

∴ y ≤ 48

x + y ≤ 100

Therefore, the given that more profit is made from the sale of low-fat latte than for regular latte, the maximum number of low-fat latte should be made

Therefore, the number of low-fat latte made, y = 48

Therefore, the number of regular latte made, x ≤ 100 - 48 = 52

For maximum profit, the maximum number of low-fat latte, 'x', should be made

Therefore, x = 52

The ideal mix of regular and low-fat lattes to maximize profit is 52 cups of regular latte and 48 cups of low-fat latte

Write the formula for Newton's method and use the given initial approximation to compute the approximations x_1 and x_2. f(x) =
Harman [31]

Answer:

x_{n+1} = x_{n} - \frac{f(x_{n} )}{f^{'}(x_{n})}

x_{1} = -10

x_{2} = -3.95

Step-by-step explanation:

Generally, the Newton-Raphson method can be used to find the solutions to polynomial equations of different orders. The formula for the solution is:

x_{n+1} = x_{n} - \frac{f(x_{n} )}{f^{'}(x_{n})}

We are given that:

f(x) = x^{2} + 21; x_{0} = -21

f^{'} (x) = df(x)/dx = 2x

Therefore, using the formula for Newton-Raphson method to determine x_{1} and x_{2}

x_{1} = x_{0} - \frac{f(x_{0} )}{f^{'}(x_{0})}

f(x_{0}) = x_{0} ^{2} + 21 = (-21)^{2} + 21 = 462

f^{'}(x_{0}) = 2*(-21) = -42

Therefore:

x_{1} = -21 - \frac{462}{-42} = -21 + 11 = -10

Similarly,

x_{2} = x_{1} - \frac{f(x_{1} )}{f^{'}(x_{1})}

f(x_{1}) = (-10)^{2} + 21 = 100+21 = 121

f^{'}(x_{1}) = 2*(-10) = -20

Therefore:

x_{2} = -10 - \frac{121}{20} = -10+6.05 = -3.95
