Asteam generation system at a biomass fueled power plant uses an electrostatic precipitator (esp) to clean its gaseous effluents. the power plant has consistently made use of the same type of esp over past several years. the installed cost of a new esp has been relatively constant at $80,000. records of operation and maintenance expenses indicate the following averag expenses per year as a function of the age of the esp the mvs of the esp are also reasonably well known as a function of age.
col1 year 1 2 3 4 5
col2 o& m expense s30,000 $30,000 s35,000 $40,000 s45,000
col3 market value 60,000 50,000 40.000 25,000 12,500
determine the best time to replace the esp if the marr is l 5% per year.

5 x 14?

im new, sorry if this is wrong.

step-by-step explanation:

to find the total number of combinations, multiply the quantity of each item by each other:

2 pairs of shoes x 3 pairs of shorts = 6 different combinations.

step-by-step explanation:

the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

the root or roots of a polynomial are the values of the variable that makes the polynomial equal to 0. we can find the roots of a polynomial making the expression equal to 0 and then, isolating the variable (it it has just one variable).

for example, given the following polynomial:

the root or zero of the polynomial, can be found by making the expression equal to 0, and then, isolating the variable, so, finding the root we have:

therefore, we have that the root of the polynomial is equal to 2.

we must remember that the number of roots that a polynomial can have, will depend on the degree of the polynomial, a first degree polynomial have will have one single root, a second degree polynomial (quadratic expression) may have two roots and so.

hence the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

have a nice day!
