Answer:
3.14
Step-by-step explanation:
To solve this we can apply the law of sines. WIth law of sines, we have:
So, we do not know B, c or C. To find either angle or side c, we hav to find angle B first and the rest will follow. To find angle B, we can do:
So, we have
So, we have to solve:
The total revenue that is gained from the sales of the cakes is determined by multiplying the number of cakes by the price. If we let x be the number of $1 that should be deducted from the price and y be the total revenue, y = (25 - x)(100 + 5x)Simplifying, y = 2500 + 25x - 5x²We get the value of x that will give us the maximum revenue by differentiating the equation and equating the differential to zero. dy/dx = 0 = 25 - 10xThe value of x is 2.5. The price of the cake should be 25 - 2.5 = 22.5. Thus, the price of the cake that will give the maximum potential revenue is $22.5
Answer:
40
Step-by-step explanation:
Remark
This is just an ordinary Pythagorean Problem.
a = 32
b = 24
c = ?
Distance
a^2 + b^2 = c^2
32^2 + 24^2 = c^2
1024 + 576 = c^2
c^2 = 1600
√c^2 = √1600
c = 40
c = 40 The distance the trains are apart is 40 km
