Question

The _____________ extends from bottom of the ocean to the top of the mountains.​

Answer 1

Explanation:

Any real number α is said to be a zero of polynomial p(x) if

p(α)=

0.

Zero can be seen as the value of x for which the polynomial takes the value as zero.

So, if

x 2

2x+

1

is a polynomial, we know at

x=

1.

In this case, the value of

x 2

2x+

1=

0,

hence

x=

1

can be said as zero of

x 2

2x+

1

Hence, the answer is

p(α)=

0.

That is, option A is correct.

Answer 2

Answer:

Rising up from the abyssal plain, you would encounter the mid-ocean ridge, an underwater mountain range, over 40,000 miles long, rising to an average depth of 8,000 feet. Tracing their way around the global ocean, this system of underwater volcanoes forms the longest mountain range on Earth
