Answer:
Given:-
The length of copper wire (L) = 270 cm
Area of cross-sectional (A) = 0.030 
and specific resistance (ρ) =
ohm-cm.
Use the formula R=(Specific resistance*L)/A, to calculate the Resistance(R)
then,
ohm
Simplify:
R = 0.0162 ohm =
ohm
Therefore, the resistance of copper wire is,
Ω
A) 31.110
B) 0.110
When rounding to three decimal places, you consider if the number to the right of the third decimal place is less than or greater than 5. If it's less than 5, then the digit in the third decimal place stays the same. If it is greater than or equal to 5, then you round the digit in the third decimal place up by one.
Step-by-step explanation:
y-y1=m(x-x1)
y-7=4(x+8)
y-7=4x+32
4x-y=-39
Answer:
The demand will drop approximately 23 T-shirt per month.
Step-by-step explanation:
Consider the provided formula.

You currently sell T-shirts for $15 each and you raise your price by $2 per month,
That means p=$15 and 
We need to find how fast demand will drop.
So differentiate the above function with respect to time.


Substitute the respective values as shown:


Hence, the demand will drop approximately 23 T-shirt per month.
