Answer:
resistance is 1.5 ohms (1.5 Ω)
Step-by-step explanation:
R varies directly with l
R varies inversely with
We can set-up a proportionality statement as shown below:
Now, Given,
R = 1.50
l = 2
d = 1.5
We substitute and find k (the proportionality constant):
Now, we will use this value of k to solve the problem.
Given,
l = 8
d = 3
and
k = 1.6875
We find R:
The resistance is 1.5 ohms (1.5 Ω)
Answer:
D
Step-by-step explanation:
the domain of 3^x is (-∞,∞) and the range is (0,∞)
the domain of 3^x-5 is (-∞,∞) and the range is (-5,∞)
the domain doesn't change, the range (-5,∞)
