Answer:
f(x) = x^2 is a classic example
f( 3 ) = 9 and
f( -3 ) = 9, but
f^(-1)[9] is undefined because the result can be 3 and -3
Answer:The amount to be paid within the discount period is $980
Step-by-step explanation:
The term 2/10, n45
means that 2% discount is offered if the amount of invoice is paid within 10 days from the date of invoice .
n/45 means that the buyer will pay the full amount within 45 days if he /she does not pay within the discount period of 10 days .
Now if the amount is to be paid within the discount period, the amount will be
Amount to be paid= $1000- 2% of 1000
= $1000-20
=$980
For this case we have the following expression:
For this case what you should do is observe the terms that are repeated in the given expression.
We have then:
It is the term that is present in the whole expression.
Therefore, by doing common factor we have:

Answer:
<em>p = ± q / 5r + 8; Option D</em>
Step-by-step explanation:
We are given the following equation; q^2 / p^2 - 16p + 64 = 25r^2;
q^2 / p^2 - 16p + 64 = 25r^2 ⇒ Let us factor p^2 - 16p + 64, as such,
p^2 - 16p + 64,
( p )^2 - 2 * ( p ) * ( 8 ) + ( 8 )^2,
( p - 8 )^2 ⇒ Now let us substitute this into the equation q^2 / p^2 - 16p + 64 = 25r^2 in replacement of p^2 - 16p + 64,
q^2 / ( p - 8 )^2 = 25r^2 ⇒ multiply either side by ( p - 8 )^2,
q^2 = 25r^2 * ( ( p - 8 )^2 ) ⇒ divide either side by 25r^2,
q^2 / 25r^2 = ( p - 8 )^2 ⇒ Now apply square root on either side,
| p - 8 | = √( q^2 / 25r^2 ) ⇒ Simplify,
| p - 8 | = q / 5r,
| p | = q / 5r + 8,
<em>Answer; p = ± q / 5r + 8; Option D</em>
