6) A sample of water is being cooled according to the formula is given by C(t)= 80 – 2t, where t represents the number of minutes the water is cooled,
and C measures the corresponding temperature in degrees Centigrade. The
cooling period ends when the water freezes (0°). Determine the relevant
domain and range for this function.
Determine the relevant Domain and relevant Range for this function. Use
interval notation.

step-by-step explanation:

the answer is d

the answer is in the first quadrant, which make the y-int positive.

since the dots are going down, therefore the correlation is negative

i hope it is right.

step-by-step explanation:

descending order means to order the polynomials from the term with the largest exponent to the term with the smallest exponent.  

therefore, the correct answer is d.  

sinn is the total amount of students now and m were the students before, you subtract them both (n-m) and divide that by m. then, since to get a percentage from a fraction you have to multiply by 100, your answer should look like this: n-m/m*100
