Answer: 
Step-by-step explanation:
Alright, lets get started.
The given expression is given as :

We know quotient identity as :

Similarly, we know reciprocal identity as :

lets plug the value of cot and sec in given expression

cos will be cancelled, remaining will be

Using reciprocal identity again, that will equal to :
................... Answer (A)
By definition we have to:
V = I * R
Where,
V: Voltage.
I: Current.
R: Resistance.
The current, I amps, produced by a battery is inversely proportional to the resistance, R ohms. Clearing I have:
I = V / R
rewriting:
I = V * (1 / R)
answer:
The equation that models the statement is:
I = V * (1 / R)
Answer:
c=3
Step-by-step explanation:
4c+12-2c=5c-3 1. combine like terms
2c+12=5c-3 2. -5c on both sides
-3c+12=3 3. -12 on both sides
-3c=-9 4. /-3 on both sides
c=3
