Why is the earth round?

Geography
1 answer:
andriy [413]3 years ago
7 0
The Earth is round so that we have day and night. If the Earth was not round, it would not rotate and half of the world would be dead because it would never get any sunlight, and the other half would probably die because of how hot it is. Additionally, if the Earth wasn’t round we wouldn’t have balanced gravity and the Earth would be unable to revolve properly around the sun.

Hope this helps!

Let m and c represent constants with m nonzero. What is the equation of the line perpendicular to y=m(x+c) and with the same y-i
nikklg [1K]

Answer:

y = -\frac{1}{m}x + mc

Explanation:

Given

y = m(x + c)

Required

Determine an equation of a perpendicular line but with the same y intercept

y = m(x + c)

Open bracket

y = mx + mc

A linear equation is represented with:

y = ax + b

Where

a = slope

b = y\ intercept

By comparison:

a = m

b = mc

So, the slope of y = m(x + c) is m

Because the new line is perpendicular to y = m(x + c), the relationship between their slopes is:

a_2 = -\frac{1}{a_1}

Where

a_1 = slope of the first equation

a_2 = slope of the second equation

Substitute m for a_1 in a_2 = -\frac{1}{a_1}

a_2 = -\frac{1}{m}

Hence, the slope of the new equation is: -\frac{1}{m}

From the question, we understand that they have the same y intercept.

So, the equation of the new equation is:

y = -\frac{1}{m}x + mc
