Quick ! exponential modelling
the temperature (t) of a dish t minutes after it is removed from the microwave, is given by:

a) what is the initial temperature of the dish?
b) what is the temperature after,
(i) 12 minutes
(ii) 36 minutes

a) 77 degrees Celsius

bi) 40.45066 degrees Celsius

bii) 24.0764 degree Celsius

Step-by-step explanation:

I'm assuming the temperature function is:

.

a) The initial temperature can be found by replacing t with 0.

bi) We are to replace t with 12:

Just put right hand side into the calculator as:

55*(0.913)^12+22 which should output 40.45066 approximately.

bii) We are to replace t with 36:

Putting right hand side into calculator as 55*(0.913)^36+22 gives:

24.0764 approximately.

hello from mrbilldoesmath!

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3
