Engineers are building a straight underwater pipeline from a drilling platform at P to and oil refinery located at Ron a straight stretch of coastline, as shown on the map below. The distance from the platform to the refinery is 5.4 km, and the distance from the plaform to the coastline is 3.7 km. Which of the
following expressions gives the measure of the acute angle formed by the pipeline and the coastline?

1) 2/5

2) zero=0/1

3) zero=0/2

4) -4/5

5) undefined=3/0

h= 12 inches

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!

i think its doubled. let me know
