To ease your live re write each one by using sin, cos, tan, knowing well that:

cscx = 1/sin x ( sin of an angle = opposite side/hypotenuse(23)

secx = 1/cos x (cos of an angle = adjacent side/hypotenuse(23)

cotx = 1/tanx (tan of an angle = opposite side/adjacent side)

Work it out & if you have difficulties do let me know

For the graph y = 1 find the slope of a line that is perpendicular to it and the slope of a line parallel to it. Explain your an

Anon25 [30]

The slope of the parallel line is 0 and the slope of the perpendicular line is undefined

<h3>How to determine the slope?</h3>

The equation is given as:

y = 1

A linear equation is represented as:

y = mx + c

Where:

m represents the slope

By comparison, we have:

m = 0

The slope of the parallel line is:

Slope = m

This gives

Slope = 0

The slope of the perpendicular line is:

Slope =-1/m

This gives

Slope = -1/0

Slope = undefined

Hence, the slope of the parallel line is 0 and the slope of the perpendicular line is undefined

the area of a rectangular volleyball court is 1800 square feet the courts length is twice it width write a system of equations t

Marianna [84]

Answer:

The dimensions of the rectangular volleyball court are 60 ft x 30 ft

Step-by-step explanation:

Let

x ----> the length of rectangular volleyball court

y ---> the width of the rectangular volleyball court

we know that

The area of the rectangular volleyball court is equal to

$A=xy$

$A=1,800\ ft^2$

so

$1,800=xy$ ----> equation A

$x=2y$ -----> equation B

substitute equation B in equation A

$1,800=(2y)y$

$1,800=2y^2$

Solve for y

Simplify

$900=y^2$

take square root both sides

$y=30\ ft$

<em>Find the value of x</em>

$x=2y$

substitute the value of y

$x=2(30)=60\ ft$

therefore

The dimensions of the rectangular volleyball court are 60 ft x 30 ft
