Step-by-step explanation:</h3>
1. A decrease of 3.8% is equivalent to a multiplier fraction of -0.038. The only answer choice that has such a multiplier is A.
In an instance such as this, the "rate" is usually some (fractional) change in some period of time. Since the exponent must be unitless, the rate is effectively (some fraction) "per year" so that multiplying by "t" years cancels the units and results in a pure number.

<em>Comment on the exponential</em>
If the actual change were -3.8% per year, the exponential term would look like (1 - 0.038)^t = 0.962^t. By writing it as e^(-0.038t), the decrease is effectively compounded continuously. As a result, over a year's time, the decrease is actually about 3.73%, not 3.8%.

2. If ║x/2║ is a magnitude function, answer choices B and D are equivalent. Thus, we must assume it is a "greatest integer" function. Then the number of desserts prepared will be ║x/2║, and the corresponding revenue will be 1.2║x/2║. Since x is in minutes, 2 to 4 hours will be 120–240 minutes. The appropriate choice is B.
Step-by-step explanation:

#4
The pattern is the number of sides that the shape has. A triangle has 3, the square has 4, the pentagon has 5, then the next shape is a hexagon which has 6 sides, a heptagon has 7, and an octagon has 8. So draw the next three shapes after the pentagon.
#5
I'm going to set this up in a ratio for you. You are going to convert these into regular fractions. So then it becomes
8/48 = 3/x
Then you need to cross multiply. You will do 3*48 divided by 8.
(3*48) = 144
144 divided by 8 is 18.
X = 18
There were 18 adults.
