If Christy is 183.4 yards from her house, how far is she from the bus stop? yards Preview c. Let the variable a represent Chrisy's varying distance from her house (in yards). As Christy walks from her house to the bus stop, the value of a varies from to d. How many values does the variable z assume as Christy walks from her house to the bus stop?

Answer:

a) 370 yards

b) 196.6 yards

c) z ∈ (0, 380)

d) The variable z assumes infinite values, since there are infinite position numbers from z = 0 yards to z = 320 yards.

Step-by-step explanation:

a) (380 - 10 ) yards = 370 yards

b) (380 - 183.4) yards = 196.6 yards

c) and d)

This situation can be described as a horizontal line that begins at point

P₁ = 0 yards (Christy's house) and ends at P₂  = 320 yards (Bus stop). Where a is the varying distance from her house, which can be calculated in the following way:

z = Final Position - Initial Position

As Christy walks from her house to the bus stop, the variable z assumes infinite values, since there are infinite position numbers from z = 0 yards to z = 320 yards.
