Find the midpoint of the segment with the given endpoints. (9,9) and (-1,- 3)

GenaCL600 [577]

Answer: (4, 3)

Step-by-step explanation:

The formula for coordinate of the mid point is given as :

Mid point = ( $\frac{x_{2}+x_{1}}{2}$ , $\frac{y_{2}+y_{1}}{2}$ )

$x_{1}$ = 9

$x_{2}$ = -1

$y_{1}$ = 9

$y_{2}$ = -3

Substituting the values into the formula , we have :

Mid-point = ( $\frac{-1+9}{2}$ , $\frac{-3+9}{2}$ )

Mid-point = ( $\frac{8}{2}$ , $\frac{6}{2}$ )

Mid - point = ( 4 , 3)

Tan 1.1 – tan 4.6/

VladimirAG [237]

The value of the given equation is –0.37458.

Solution:

Given equation is:

$$\frac{\tan 1.1-\tan 4.6}{1+\tan 1.1 \tan 4.6}$

Let us first find the values.

The value of tan 1.1 = 1.96475

The value of tan 4.6 = 8.86017

Substitute these values in the given equation.

$$\frac{\tan 1.1-\tan 4.6}{1+\tan 1.1 \tan 4.6}$

$$=\frac{1.96475-8.86017}{1+1.96475 \times 8.86017}$

$$=\frac{-6.89542}{1+17.4080}$

$$=\frac{-6.89542}{18.4080}$

= –0.37458

$$\frac{\tan 1.1-\tan 4.6}{1+\tan 1.1 \tan 4.6}=-0.37458$

Hence the value of the given equation is –0.37458.
