That equation can represent the relationship among the image distance,
object distance, and focal length of a lens. 

It could describe the effective resistance of two resistors in parallel, the
effective inductance of two coils in parallel, or the effective capacitance
of two capacitors in series. 

Thanks for sharing it.  Now, did you have a question to ask ?

A publisher displays its latest magizine on its website
IceJOKER [234]

We need to know about unitary method to solve the problem. The length of the actual magazine cover is 8 inches, the width of the actual magazine cover is 11 inches, the length of the new magazine cover is 32cm and the width of the new magazine cover is 44cm.

Unitary method is used to find the value of a unit object. . In this question we know the scale is 6cm to 1 inch for actual magazine cover, the length is given to be 48 cm and the width is 66cm,

length of actual magazine cover= 48/6=8 inches

width of actual magazine cover= 66/6=11 inches

The new scale is 4 cm to 1 inch

length of new magazine cover=8x4=32 cm

width of new magazine cover =11x4=44 cm

Therefore the length of the actual magazine cover is 8 inches, the width of the actual magazine cover is 11 inches, the length of the new magazine cover is 32 cm and the width of the new magazine cover is 44cm.

I'm doing Pre-algebra and I don't know how would I figure out the 13th term of the pattern; 100, 91, 82, 73.... without writing
Over [174]
The way we would answer the question would be to express it as

100-9(n-1) with n being the nth term of the pattern.

Why is this? We know we subtract 9 each time and START from 100.
Remember though that 100 is the first term in the sequence. So, we would have (n-1)*9 to subtract 0 from our 1st term and 9 from our second term.

Also, we have 9*(n-1) because we are just subtracting multiples of 9. It is always going to subtract by 9.


If you needed the answer here it is...

The answer to the problem would be 
100-9(13-1)
= 100-9(12)
= 100-108
= -8
