Ответ:
(-8-9(t+d)-(-8-9t))/(t+d-t)
(-8-9t-9d+8+9t)/d
-9d/d (which is -9 for any value of d as well as when d approaches zero)
-9
So the instantaneous velocity is regardless of t or delta t
Ответ:
2|x - 6| + 14 = 38
2|x - 6| = 38 - 14
2|x - 6| = 24
|x - 6| = 12
Simplifying |x-6| = 12 can be done in two ways:
A.)
|x - 6| = 12
x - 6 = 12
x = 18 (maximum temperature)
B.)
|x - 6| = 12
x - 6 = -12
x = -6 (minimum temperature)
