<h3>Answer:   D) It is affected by tides.</h3>

==========================================================

Explanation:

An estuary is where a river pours into the ocean. So that means fresh water mixes with salt water here. This allows us to rule out choices A and B.

According to NOAA, their site says "Estuaries are one of the most productive ecosystems in the world, so there is a great diversity of animals and plants that live there". In other words, a lot of plants and animals live here, so we can rule out choice C.

Choice D is the answer because tides do affect estuaries. This is simply because the ocean is pretty much right next to it, or attached to it. So it's expected that a high tide would cause the water level in an estuary to increase.

Answer:

see explanation

Step-by-step explanation:

Using the trigonometric identities

• tanx = \frac{sinx}{cosx}

• sin²x + cos²x = 1 ⇒ sin²x = 1 - cos²x

Consider the left side

\frac{tan^2x-sin^2x}{tan^2x}

= \frac{tan^2x}{tan^2x} - \frac{sin^2x}{tan^2x}

= 1 - cos²x

= sin²x = right side ⇒ verified

Help pls, I’m confused
Alecsey [184]

Answer:

(x + y)² = 25

Step-by-step explanation:

The expansion of (x + y)² is

(x + y)² = x² + y² + 2xy ← substitute x² + y² = 15 and xy = 5

           = 15 + 2(5)

           = 15 + 10

           = 25

About 450 books and articles Euler completed after he lost his sight entirely.

<h3>Who was Leonhard Euler?</h3>

Leonhard Euler was a mathematician from Switzerland. He introduced the fundamentals of graph theory and topology.

His main field of work includes number theory, mechanics, fluid mechanics, and many more.

The life span of Euler was between 1707 and 1783. In the last few years of his life, he lost the eye sight. But the eye sight loss doesn't affect him from doing his work. In his lifespan, he published around 886 books and articles on various fields or science, mathematics and engineering.

After the total blindness, he published more than 450 books and articles.
