Please simply and with detail explain cos/sin/tan and where they are used, and show examples of specificly where they would be used. I already learned this a few months ago, but its been bugging me that I didnt know it as well as I should have. If you really help me out and give exmaple, and detailed explenation and what they are and where they are used I will give and post free-b 25 more points!

0/5 is 0, 2/0 is undefined, and 0/0 is indeterminate.

step-by-step explanation:

hope my answer has you!

5   1/4   miles per hour

step-by-step explanation:

15   3/4 / 3 = 5   1/4

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!
