Answer:
1/16
Step-by-step explanation:
Here: 64x^2+12x = 1
Then, 64x^2 +12x -1=0
The delta = 12^2 - 4*64*(-1)= 400 = 20^2
These two solutions are:
(-12+20)/(2*64)= 8/(2*8*8)= 1/16
(-12-20)/(2*64) but this is negatif.
1/16 is the positif solution.
Hope that useful for you.
Answer:: D(t)= 50(4/5)^t
Step-by-step explanation: If 1/5 of the temperature difference is lost each minute, that means 4/5 of the difference remains each minute. So each minute, the temperature difference is multiplied by a factor of 4/5 (or 0.8).
If we start with the initial temperature difference, 50° Celsius, and keep multiplying by 4/5, this function gives us the temperature difference t minutes after the cake was put in the cooler.
Answer:
the value of 2 in 0.812 is 2 thousandths/0.002
0.002 = 2/1000
