Answer:
F = 6
Step-by-step explanation:
find the constant of variation (k) first by using this formula:
f = k/d
plug in given info to find k: 3 = k/4 so k = 12
use 12 to find F: F = 12/2
Answer:
A. d/2 = r
B. r=65 miles/hour

The 5 is on the ten thousand place.
Given that the value of an industrial machine has a decay factor of 0.75 per year, and after six years, it became $7,500 only, this would mean that the original value of the machine would be solved like this: <span>7500 = x(1-.75)^6
</span>7500 = x(0.25)^6
7500 = x(<span>0.00024414062)
7500 = </span><span>0.00024414062x
x = </span><span>30, 720, 000
Hope this answers your question.</span>
