Answer:
7 apples divided among 5 people
Step-by-step explanation:
Given
Apple shared equally
Portion of each person = 7/5
Required
A possible way that shows how the pies were shared.
Given that 7/5 is the ration of the pie to each individual (Kyle and his friends).
Provided that each individual got equal ration....
The ration can be divided into two
The numerator = 7
The denominator = 5.
The numerator shows the number of things that were shared.
Hence, 7 apples were shared.
The denominator shows the number of people involved.
Hence, 5 people were involved.
So, we can conclude that 7 apples were divided among 5 people.
From option A through D, only option B satisfied this analysis
Answer:
I think it's option B ...

y = 2
x = 1
z(the hypotenuse) = √(2^2 + 1^2) = √5
Cos(u) = x value / hypotenuse = 1/√5
Sin(u) = y value / hypotenuse = 2/√5
Solve for sin2u
Sin(2u) = 2*sin(u)*cos(u)
Sin(2u) = 2() = 4/5
Solve for cos(2u)
cos(2u) = - sqrt(1 - sin^2(2u))
Cos(2u) = - sqrt(1 - (4/5)^2 )
Cos(2u) = -sqrt(1 - 16/25)
cos(2u) = -sqrt(9/25)
cos(2u) = -3/5
Solve for Tan(2u)
tan(2u) = sin(2u) / cos(2u) = 4/5// - 3/5 = - 0.8/0.6 = - 1.3333 = - 4/3
Notes
One: Notice that you would normally rationalize the denominator, but you don't have to in this case. The formulas are such that they perform the rationalizations themselves.
Two: Notice the sign on the cos(2u). The sin is plus even though the angle (2u) is in the second quadrant. The cos is different. It is about 126 degrees which would make it a negative root (9/25)
Three: If you are uncomfortable with the tan, you could do fractions.
