An explicit formula for a sequence allows you to find the value of any term in the sequence. A recursive formula for a sequence allows you to find the value of the nth term in the sequence if you know the value of the (n-1)th term in the sequence.

Answer:

$a^2(ab^{3}-b^{2}-c^{2})$

Step-by-step explanation:

Given

$a^{3}b^{3}-a^{2}b^{2}-a^{2}c^{2}$

Required

Factor

$a^{3}b^{3}-a^{2}b^{2}-a^{2}c^{2}$

Factor out $a^2$

$a^2(ab^{3}-b^{2}-c^{2})$

<em>The expression cannot be further factored</em>

A scale drawing of a building has the scale 0.5in : 6ft. A wall is 30 ft long. How long will the wall be on the drawing?

g100num [7]

The scale 0.5 in : 6 ft, means that

any distance of 0.5 in on paper, represents 6 ft in reality

for example:

0.5*2= 1(in) represents 6*2=12 (ft)

0.5*4= 2(in) represents 6*4=24 (ft)

0.5*10=5(in) represents 6*10=60 (ft) and so on...

Let the wall be x (in) in the drawing:

0.5 (in) represents 6 (ft),
x (in) represents 30 (ft)
----------------------------------------

thus x = (0.5*30)/6 = 15/6= 2.5 (in)

Answer: 2.5 in
