Answer:

So m= - 11

Step-by-step explanation:

* THe vertex is (-2,6), then the equation is y = a(x+2)^2 +6, a is to find out.

* A root is 7 means x=7 and y=0, then :

0 = a(7+2)^2 +6

0=81a+6 or a= -6/81  = -2/27.

* We have the equation: y= -2/27 (x+2)^2 +6=-2/27 [ (x+2)^2-81]

y= -2/27 (x-7)( x+11).

So m= - 11

Hope that you understand.

You place a cup of 200 degrees F coffee on a table in a room that is 67 degrees F, and 10 minutes later, it is 195 degrees F. Ap
Serga [27]

Answer:

It will take a total of twenty minutes

Step-by-step explanation:

if it cools from 200 to 195 in five minutes then times two is twenty which means it's cooled to 190.

180 is twenty less then 200 so if it takes ten minutes to cool down by ten then multiply this by two and you get 180 and know it's cooled by twenty minutes
