We are given that tanx = 25.

We are also given tan(π−x).

Apply distributive rule to
tan(π−x).

tanπ − tanx

Take it from here knowing that tanx has been given to be 25.

Given tan(x)=25
we need to find tan(π-x)=cot(x) = 1/tan(x) = 1/25

Answer: tan(π-x)=1/25.

Evaluate the dot product of (7, 5) and (- 5, 4)

Answer:

The dot product of (7,5) and (-5,4) is -15

Step-by-step explanation:

Given

(7,5) and (-5,4)

Required

Determine the dot product

Dot product is calculated using the following formula;

$a.b = {a_1b_1+a_2b_2+...+a_nb_n}$

Let a = (7,5) and b = (-5,4);

The above formula becomes

$a.b = {7*-5+5*4}$

$a.b = {-35+20}$

$a.b = {-15}$

Hence, the dot product of (7,5) and (-5,4) is -15

Answer:

$\frac{x}{y} \frac{5x}{\frac{x^{2} -4}{\frac{8x}{x+2} } }\\\\=\frac{5x(x+2)}{8x(x^{2} -4)}\\\\=\frac{5(x+2)}{8(x+2)(x-2)}\\\\=\frac{5}{8(x-2)}\\\\=\frac{5}{8}.\frac{1}{x-2}$
