Answer:

all options are correct.

Step-by-step explanation:

The correct options among all the options are:

  • <em>Ancient mathematicians used trigonometry to find angles of triangles.</em>

        Trigonometry is used to find the size of a missing side or angle in a right-    angled triangle using the sine, cosine or tangent ratios.

  • <em>Ancient mathematicians used trigonometry to track the position of the sun.</em>

It is also used in oceanography in calculating the height of tides in oceans.

  • <em>Tangent was the first trigonometric relationship used by mathematicians.</em>

The three main functions in trigonometry are Sine, Cosine and Tangent.The functions sine, cosine and tangent of an angle are sometimes referred to as the primary or basic trigonometric functions.

  • <em>Cosine was the first trigonometric relationship used by mathematicians. </em>
  • <em>Sine was the first trigonometric relationship used by mathematicians.</em>

A pool company offers a pool with dimensions x and 2x. They also include a 3 foot deck around the entire pool.
Vitek1552 [10]

Answer:

1)   area = (x + 3)(2x + 3) ft²

2)   299 ft²

Step-by-step explanation:

<u>Question 1</u>

Area of a rectangle = width x length

Given:

  • width = x + 3
  • length = 2x + 3

⇒ area = (x + 3)(2x + 3) ft²

<u>Question 2</u>

If x = 10:

⇒ area = (10 + 3)(2(10) + 3)

            = 13 · 23

            = 299 ft²

When a certain prescription drug is taken orally by an adult, the amount of the drug (in mg/L) in the bloodstream at t hours is
castortr0y [4]

Answer:

1. y = f(8)

2. So for t which f'(t) > 0, the drug level in the bloodstream is increasing. And for t which f'(t) < 0, it is decreasing.

Step-by-step explanation:

The concentration of the drug in the bloodstream at t hours is:

y = f(t)

1. What is the concentration of the drug in the bloodstream at t= 8 hours?

At t hours, y = f(t)

So at 8 hours, y = f(8)

2. During what time interval is the drug level in the bloodstream increasing? Decreasing?

A function f(t) is increasing when

f'(t) > 0

And is decreasing when

f'(t) < 0

So for t which f'(t) > 0, the drug level in the bloodstream is increasing. And for t which f'(t) < 0, it is decreasing.

How to find a perfect square in square roots
Lemur [1.5K]

Answer:

To find a number's square root, determine which two perfect squares the number lies between and estimate a fraction between those two perfect square roots. If it is a perfect square itself the square root can be arrived at precisely. If not, divide the number by one of the two closest square roots and average the result with the root. So  there really isn't any answer to accurately do this that i'm aware of hope this helped!
