dolphi86 [110]

Answer:

(x - 1)(x - 2)(x + 3)

Explanation:

f(x)=x3-7x+6 Since (a + b + c + d = 0), then f(1) = 0 --> one factor if (x - 1).

After division -->

f(x)=(x-1)(x2f2+x-6). The trinomial in parentheses can be factored.

Find 2 numbers knowing sum (1) and product (-6). They are -2 and 3.

Therefor, f(x)=(x-1)(x-2)(x+3)

What is the savanna hypothesis? Group of answer choices Bipedalism was selectively favored because it helped our ancestors to st
Gnom [1K]

Answer:

Both options are valid, since in the hypothesis of the savanna it was argued that humans acquired bipedalism to be able to self-supply their food more effectively, and to have less body surface area exposed to the sun.

Explanation:

The saban hypothesis is believed to have originated in the saban, with the Austrolopitecus africanus being forced to affect this domain, which is why it acquired this adaptation mechanism.

The savanna had high grasslands, which also led to collaboration in this regard since they could be better camouflaged.

In addition, the human began to defend with the limbs of the upper limb, triggering the canines to decrease in size since it is not used as a defense mechanism.

The canine is a tooth that helps to tear carnivorous food, that is why the human also begins to have a more varied diet of fruits and seeds and that it can reach and take the bones of the tree to increase its height due to bipedalism.

Answer choices are:


A. Invalidate, because energy should not leave a closed system

B. Invalidate, because the amount of energy should stay constant

C. Validate, because an aquarium is an open system that loses and gains energy

D. Validate, because the amount of energy lost was replaced by matter.

The correct answer choice is:

C. Validate, because an aquarium is an open system that loses and gains energy.


Explanation:


As we know that, the law of conservation of energy is that the total amount of energy of an isolated system prevails to be constant, it is said to be maintained or conserved over time. This law means that energy can neither be created nor be destroyed; rather, it can only be converted or transferred from one form to another.
