Question 54383: I have two questions I'm stumped on. One is Suppose the rectangular TV screen measures 50" on the diagonal and 30" in height. What is its width?
The other is The speed of light is approx 3 x 10^5 km/sec. Write an equation which is a function of distance y and time x.

Hypotenuse ~> 50 inches
Leg ~> a
Leg ~> 30 inches
a^2 + 30^2 = 50^2
a^2 + 900 = 2500
a^2 = 1600
a = 40
The width is 40 inches exactly.
Distance (y) = Rate (3 x 10^5) * Time (x)
y = 300,000x
