A chocolate bar contains 50 calories and s of protein and makes a
Alla [95]

Answer:

He should serve 2 chocolate bars and 2 granola bars

Step-by-step explanation:

Let's define

x: amount of chocolate bar  

y: amount of granola bar

We are asked to solve the following optimization problem:

maximize 7*x + 2*y  

subject to

50*x + 25*y ≤ 150

5*x + 15*y ≥ 40

x ≥ 0

y ≥ 0

In the figure attached, the feasible region is shown. The solution is one of the vertex

vertex            objective function

(0, 2.667)       7*0 + 2*2.667 = 5.334

(2, 2)               7*2 + 2*2 = 18

(0, 6)               7*0 + 2*6  = 12

Can I get help on this
emmainna [20.7K]
The equation for cosine is the adjacent/hypotenuse. Looking at our L, the letter right next to it is the lowercase l, so that is the adjacent. The hypotenuse is always the side opposite the right angle, so the hypotenuse in this question is the lowercase m. The answer for the first question, then, is k/m. For the second question, you are asked to find the side of q. In questions like these, always start from the angle given to you. Start from the 51 degrees. Right next to the 51 degrees is q, so q is the adjacent. We also have a number, 134, which is opposite the given angle 51. Now use the trigonometric ratio that involves adjacent and opposite, which is tan. Therefore, tan51 is the right answer. Hope this helps! Ask me for more help.
