Answer:
a = 132 m/s^2
Explanation:
f(t) = t^4 − 2t^3 − 6t^2 + 9t
v = f'(t) = 4t^3 - 6t^2 - 12t + 9
a = f''(t) = 12t^2 - 12t -12
Substitute t = 4 seconds into the equation for a:
a = 12(16) -12(4) -12 = 132 m/s^2
Answer:
Starting in the 1900s, technologies and industrial developments advanced enormously, modifying the living conditions of human beings in general, throughout the entire width and length of the earth's surface.
Thus, starting with the Industrial Revolution of the mid-1800s, technologies such as the steam engine and the development of automated means of production generated a series of technological advances that allowed a greater modification of the environmental environment of human beings, in in order to guarantee better living conditions.
Now, these modifications, which at first were not harmful or at least not to a great extent, over the years and the development of technological advances began to impact the environment: the extraction of raw materials began To generate scarcity of them, the emission of gases into the atmosphere began to generate the phenomenon of global warming, and even indiscriminate hunting led to the extinction of hundreds of thousands of animal species.
