Mathematics
1 answer:
andrezito [222]2 years ago
4 0

Answer:

x = y² + 12x

y² = x - 12

y² = -11x.

Step-by-step explanation:

We need to find the inverse of the given function , which is ,

\rm\implies y = x^2 + 12x

Step 1 : <u>Interchange</u><u> </u><u>x </u><u>and </u><u>y </u><u>:</u><u>-</u><u> </u>

\rm\implies x = y^2 + 12y

But according to the steps given in the Question , in very first step in 12x , x is not replaced by y . After which , the steps go wrong in the question .

<u>The </u><u>3 </u><u>errors </u><u>:</u><u>-</u><u> </u>

  • x = y² + 12x
  • y² = x - 12
  • y² = -11x.

Nata [24]

Answer:

-4u+2v = <-6, 34>

Step-by-step explanation:

u = <4, -7) → -4u = <-16, 28>

v = <5, 3> → 2v = <10, 6>

-4u+2v =  <-16, 28> + <10, 6> = <-6, 34>

Is Social Darwinism a justifiable reason to colonize other areas of the world and exploit the people and resources of that regio
Ksivusya [100]

Answer:

Social Darwinism provided an ideological justification for the social inequalities that capitalism had brought with it: these would result from the hereditary inferiority of the poor and the hereditary excellence of the richer classes, which are best enjoyed under a laissez-faire system. Applied to peoples and races, it became a justification for racism and imperialism.

As can be seen, social Darwinism is a retrograde political and philosophical stance, which considered different ethnic or national groups as different in terms of capacity or development possibilities. Therefore, since this position has been regarded as false, social Darwinism has no justification in our time.

Challenge Yossi used to have a square garage with 246 ft of floor space. recently built an addition to it. The garage is still a
irina [24]

Considering the perimeter of a square, it is found that:

  • The length of one side of the garage​ originally was of 61.5 ft.
  • The length of one side of the garage​ now is of 92.25 ft.
  • The percent increase in the length of one​ side was of 50%.

<h3>What is the perimeter of a square?</h3>

The perimeter of a square of side length s is given by four times the length, that is:

P = 4s.

Before the change, the perimeter was of 246 ft, hence:

4s = 246

s = 246/4

s = 61.5.

The length of one side of the garage​ originally was of 61.5 ft.

After that, the perimeter increased by 50%, hence:

P = 246 x 1.5 = 369.

4s = 369

s = 369/4

s = 92.25.

The length of one side of the garage​ now is of 92.25 ft.

The percent increase is the increase divided by the initial value, hence:

(92.25 - 61.5)/61.5 = 50%.

The percent increase in the length of one​ side was of 50%.
