Answer:
Option B. square root
Step-by-step explanation:
An incoming airplane is x miles due North at A from the control tower and a second airplane is y miles East at B of the same control tower.
The shortest distance between the two airplanes is z miles.
By Pythagoras Theorem
z² = x² + y²
z = √(x² + y²)
So function which models the situation best is "square root".
Therefore, option B. square root is the answer.
Answer:
Step-by-step explanation:
Probability (P) is calculated as
P =
The first required outcome is a red sweet from a total of 3 + 5 = 8
P( red) =
There are now 2 red left and a count of 7, since 1 has been eaten, thus
P( second red ) =
P( red and red ) = ×
=
=
Answer:
B
Step-by-step explanation:
A proportional relationship is represented by linear function with its linear parameter "b" equal to zero. Since b is equal to zero, the line passes through the origin and the function/relation is proportional.
To verify that we divide the y coordinate over the x coordinate we obtain a constant called k, which is the slope.
For instance:
According to this function we can easily check a proportional relationship among its points:
