Find the exact value of tan5x/4

1 answer:

7 0

To evaluate for tan 5x/4 we proceed as follows
5x/4
=5/4*150
=225
which is in quadrant III.
This implies that the value of tan will be positive, hence:
tan 225=tan (270-225)
tan 225=tan 45
using right angle with length of the legs being unit, then
tan 45=1
hence
tan 5x/4=1

Complete the point-slope equation of the line through ( − 5 , 4 ) (−5,4)left parenthesis, minus, 5, comma, 4, right parenthesis

Tanzania [10]

The point slope form of equation through given points is:

$y-6=\frac{1}{3}(x-1)$

Step-by-step explanation:

Given points are:

(x1,y1) = (-5,4)

(x2,y2) = ((1,6)

First of all we have to find the slope of line

So,

$m=\frac{y_2-y_1}{x_2-x_1}\\=\frac{6-4}{1+5}\\=\frac{2}{6}\\=\frac{1}{3}$

Point-slope form is given by:

$y-y_1=m(x-x_1)$

Putting m=1/3

$y-y_1=\frac{1}{3}(x-x_1)$

Putting (1,6) in the equation

$y-6=\frac{1}{3}(x-1)$

The point slope form of equation through given points is:

$y-6=\frac{1}{3}(x-1)$

snow_lady [41]

Answer:men=152 women=76 children=38

Step-by-step explanation:

men+women+children=266
men=4*children
women=2*childrens
so let say x represent the numebers of children the equatin becomes: 4x+2x+x=266
solve for x =38 so the numbers of children is 38
men=4*38=152
women=2*38=76

If the edge length of a cube is 11 feet, what is the correct way to write the expression to represent the volume of the cube in

satela [25.4K]

Answer:

(11 ft)³

Step-by-step explanation:

Given the shape is a cube, all of its sides are the same.

The formula for the volume of a cube is V = s³ where "s" represents the edge length.

Substitute "s" for 11 ft.

V = s³

V = (11 ft)³

In exponential form, do not solve for the volume. Leave the expression as

(11 ft)³

Without the units, the answer is 11³
