Answer: 2.44 inches
Step-by-step explanation:
Since the scale on a map of Virginia shows that 1 inch = 45 miles while the actual distance from Richmond, Va, to Washington, D.C., is 110 miles.
The number of inches that are between the two cities will be represented by x. Therefore,
1/x = 45/110
Cross multiply
45x = 110
x = 110/45
x = 2.44 inches
The Distance between the two cities on the map is 2.44 inches
From the description, we have the function
Since the square root cannot be a negative number, the only thing need to do to find the domain of the function
is take the expression inside the square rot and set it greater or equal than zero:
or
We can conclude that we can use the inequality
to find the domain of
. Also, the domain of
is (∞,
]U(5,∞).
Both calculated the slope as 2/3

An example would be:

Answer: Choice A) 29.5 </h3>
This value is approximate.
=========================================================
Work Shown:
First we need to find angle C
A+B+C = 180
46+73+C = 180
119+C = 180
C = 180 - 119
C = 61
This is not the final answer, so answer choice B is likely a trick/trap answer.
We'll use this angle value to help find side c. Use the law of sines
c/sin(C) = b/sin(B)
c/sin(61) = (32.3)/sin(73)
c = sin(61)*(32.3)/sin(73)
c = 29.5410185554849 which is approximate
c = 29.5 which points us to choice A as the final answer.
