Answer:
a. Graph A: Cost vs Volume
Graph B: Calories vs Volume
b. Graph B (Calories vs Volume)
c. k = 15
Step-by-step explanation:
a. It is not possible for a volume of 10 oz of drink to be sold for $150. It doesn't make common sense. Also, calorie level of 150 in 10 oz of drink seem plausible.
It makes more sense if 10 oz of the drink cost $3.75. Therefore, the graphs should be titled as follows:
Graph A: Cost vs Volume
Graph B: Calories vs Volume
b. The quantities in Graph B (Calories vs Volume) appear to be in a proportional relationship. We know this because if we try drawing a line to connect the points on the graph, it will give us a straight line. A straight line connotes proportionality.
Also the ratio of the quantities of the two known points given are the same. I.e. ![\frac{150}{10} = \frac{360}{24} = 15](https://tex.z-dn.net/?f=%20%5Cfrac%7B150%7D%7B10%7D%20%3D%20%5Cfrac%7B360%7D%7B24%7D%20%3D%2015%20)
Therefore the quantities compared in Graph B shows a proportional relationship.
c. Constant of proportionality = ![\frac{150}{10} = \frac{360}{24} = 15](https://tex.z-dn.net/?f=%20%5Cfrac%7B150%7D%7B10%7D%20%3D%20%5Cfrac%7B360%7D%7B24%7D%20%3D%2015%20)
The answer will be D. 100, this is because they show u that angle A is 55 meaning so is angle D because they r congruent, then they tell u that angle E is 25 meaning so is angle B because they r congruent, so now u have to add those up and get 80, now subtract that from 180 which has to be your total of the 3 angles and get 100
Hope this helps
Answer:
cos x
Step-by-step explanation:
sec x - tan x sin x
![\frac{1}{cosx} - \frac{sinx}{cosx} * sinx\\\\\frac{1}{cosx} - \frac{sin^{2}x}{cosx}\\\\\frac{1-sin^{2}x}{cosx} \\\\\frac{cos^{2}x }{cosx} \\\\cosx](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7Bcosx%7D%20-%20%5Cfrac%7Bsinx%7D%7Bcosx%7D%20%2A%20sinx%5C%5C%5C%5C%5Cfrac%7B1%7D%7Bcosx%7D%20-%20%5Cfrac%7Bsin%5E%7B2%7Dx%7D%7Bcosx%7D%5C%5C%5C%5C%5Cfrac%7B1-sin%5E%7B2%7Dx%7D%7Bcosx%7D%20%20%5C%5C%5C%5C%5Cfrac%7Bcos%5E%7B2%7Dx%20%7D%7Bcosx%7D%20%5C%5C%5C%5Ccosx)
