What kinds of things do firefighters need to carry? What do you think this means for the angle of the ladder they’re willing or able to climb?

Given

Step-by-step explanation:

A firefighter needs to carry an LED flashlight, a knife or axe, a wax pencil. Every firefighter will put these to use regularly. Two other essential items are dust masks and earplugs. In addition to this they require fire protective gear and clothes.

The angle of the ladder is suitable to be around 75° for rescue operations and for firefighters to climb and perform tasks effectively.

Hope this is helpful..

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!
