Answer:
I hope this helps-How to define a logarithmic unction-
Step-by-step explanation:
Therefore, the (multiple-valued) logarithmic function of a nonzero complex variable z=reiΘ is defined by the formula logz=lnr+i(Θ+2nπ)(n∈Z).
Some basic properties of the function logz are the following:
log(z1z2)=logz1+logz2.
log(z1z2)=logz1−logz2.
There may hold Log(z1z2)≠Logz1+Logz2.
Answer:
It will take 9 hours with 4 painters to paint 720 feet of fence.
Step-by-step explanation:
Given that,
The time needed to paint a fence varies directly with the length of the fence
.......(1)
and inversely with the number of painters
.....(2)
Combination of (1) and (2) is
where t represents time, 
represents length of fence, P represents number of painters.
Again we can write the above equation as
Given that,
It takes 7 hours with 2 painters to paint 280 feet of fence .
We need to find time to paint 720 feet of fence with 4 painters.
=7 hours, 
=280 feet, 
=2,
=? , 
= 720 feet, 
=4
It will take 9 hours to paint 720 feet of fence with 4 painters.
Answer:
48cm
Step-by-step explanation:
The perimeter of first shape is 36cm. There are 3 semi circle (curves).
Therefore,
3 curves of semicircle (arc length) = 36
1 curve of semicircle (arc length) = 36/3
= 12cm
In picture 2,
4 semicircles (They've mentioned that they used the same semicircle for the 2nd shape also)
So,
4×12 = 48cm
Each page from 10 to 99, inclusive (so total of 90 pages) needs two digits (for example page 12 needs two digits: 1 and 2); Each page from 100 to 200, inclusive (so total of 101 pages) needs three digits (for example page 123 needs three digits: 1, 2 and 3)
15x10=150
Subtract 5x5=25 small square cut out
150 -25= 125 sq ft
