Let f(t) represent the tempreture of a turkey baking in a oven as a function of time in the oven (in minutes). this means time is the independent varible and tempreture of the turkey is the dependent varible. the turkey was in the oven for 360 minutes and then removed. note that when something is baked in a oven, the tempreture of the oven stays constant explain the meaning of each statement in the context of the situation using everyday language remember that the imput of the function t is the time in the oven and the output f(t) is the temperture of the turkey at that time

ok f(t) is a function that says how the temperature of the turkey change as the time goes. When it says that the time is and independent variable and the temperature the dependent variable, it means that the time not depends on anything, you can let the turkey in the oven as much time as you want, but the temperature depends on the time the thing was on the oven, ence the temperature is dependent.

when yo say that the turkey was removed after 360 mins, this means that our function f(t) goes from t = 0mins to t =360mins, if the temperature of the oven remains constant, then the temperature of the turkey can only augment as a the time pases, until it has the same value than the temperature of the oven.

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
