Answer: Combats social exclusion and discrimination. Promotes scientific and technological progress.
The correct answer is C. It is used to determine the absolute dates in years for different periods.
Explanation
The geological timescale is a tool that has been developed over the years by geologists to establish a frame of reference in which important events in the history of the Earth and life are represented in chronological order. This scale is organized from divisions and subdivisions, from the relative age of the rocks according to their relative age and the absolute time elapsed since the formation of the Earth to the present. Through this scale it has been possible to establish historical periods such as when dinosaurs lived. So the correct answer is C.
I believe the correct answer from the choices listed above is option D. The number of stars you would find in a galaxy would be billions. Galaxies can contain billions of stars and have a massive size. As you can see in the night sky, the stars cannot be counted.
Mountains have an extremely important role in influencing global and regional climates and weather conditions. They cover around one-quarter of the earth's land surface and are home to 720 million people around the world. Indirectly, billions more living downstream also benefit from mountains.
Mountains provide us with freshwater, energy, food, biodiversity, and medicinal products – resources that may become very rare in the coming decades.
Explanation:
(f o g)(x)
= f[g(x)]
= f(3x + 7)
= 5(3x + 7) - 4
= 15x + 31.
When (f o g)(k) = 7, 15k + 31 = 7.
=> 15k = -24, k = -8/5 = -1.6.
