Answer:
45 pints
Step-by-step explanation:
The maximum value of the function y= -3+4 cos(5pi/6(x+4)) can be determined by differentiating the equation then make the derived function equal to zero. In this case, the function becomes 4 sin (5pi/6(x+4)) * (5pi/6) or equal to 10pi/3 sin (5pi/6(x+4)) = 0. sin -1 of 0 is equal to zero. hence, 5pi/6(x+4) should be zero. x is equal to -4. substituting -4 in the original equation,<span>y= -3+4 cos(5pi/6(-4+4)) is equal to 1. The maximum value is 1. </span>
Answer: Each candy costs and each drink costs
Step-by-step explanation:
We are told Dominic bought 2 drinks and 5 candies, costing a total of :
(1)
Then, we are told Colton bought 8 drinks and 7 candies, costing a total of :

Now we have a system with two equations ans two unknowns. Let's solve it:
Multiplying (1) by -4:
(3)
Summing (2) and (3):
(4)
Isolating :
(5) This is the cost of each candy
Substituting (5) in (1):
(6)
Isolating :
(7) This is the cost of each drink
