2n = 11-7

2n = 4

n = 4/2

therefore n = 2

Special right triangle
Karo-lina-s [1.5K]

Answer:

Step-by-step explanation:

6) taking 45 degrees as the reference angle,

the adjacent side is √6

The opposite side is x

The hypotenuse is y

Therefore, we would apply trigonometric ratio.

Tan # = opposite side / adjacent side

Tan 45 = x/√6

1 = x/√6

x = 1 × √6 = √6

Cos # = adjacent side/hypotenuse

Cos 45 = √6/y

Cos 45 expressed in surd form is √2/2. Therefore,

√2/2 = √6/y

y √2 = 2√6

y = (2√6)/√2

Find the derivative of 1/√s+2
QveST [7]

Using the quotient rule, it is found that the derivative of the function is given as follows:

f^{\prime}(x) = -\frac{1}{2\sqrt{s}(\sqrt{s}+2)^2}

<h3>What is the derivative of a quotient?</h3>

Suppose a quotient function defined as follows:

f(x) = \frac{g(x)}{h(x)}

Then, the derivative is given by:

f^{\prime}(x) = \frac{g^{\prime}(x)h(x) - h^{\prime}(x)g(x)}{h(x)^2}

In this problem, we have that:

  • g(x) = 1.
  • g'(x) = 0.
  • h(x) = \sqrt{s} + 2.
  • h^{\prime}(x) = \frac{1}{2\sqrt{s}}

Then, since g'(x) = 0, the derivative is given by:

f^{\prime}(x) = -\frac{1}{2\sqrt{s}(\sqrt{s}+2)^2}
