Answer:
10.8 cm
Step-by-step explanation:
we know that
1) A square picture with side length 30 cm is scaled by 60% on a photocopier
Remember that
so
The length of the first copy of the picture is
2) The copy is then scaled by 60% again
so
The length of the second copy of the picture is
Just has to be greater than or equal to 0... w and t can never be negative since taking the square root of a negative number yields an imaginary number which would mean imaginary current. Also the question states that w can't be zero but if T is zero than the current will be zero.
Answer:
We'd need more information like the relationship between those equations.
