Clara recorded the weather forecast in the table. radio forecast day forecast monday 5° below 0 tuesday 0° wednesday 2° below 0 thursday 3° above 0 on which day would she use a positive number to write the temperature? monday tuesday wednesday thursday

The temperature was positive number on Thursday.

Step-by-step explanation:

Given:

Clara recorded the weather forecast in the table.

On Monday she noted the temperature was 5° below 0.

It means on Monday the temperature was -5°

On Tuesday she noted the temperature was 0.

It means on Tuesday the temperature was 0°.

On Wednesday she noted the temperature 2° below 0.

It means on Monday the temperature was -2°.

On Thursday she noted the temperature 3° above 0.

It means on Monday the temperature was 3°

Now we need to find On which day would she use a positive number to write the temperature

Hence From above we can say the temperature was positive number on Thursday.

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!
