What is tan(x)-5=0<br> (With steps)
gizmo_the_mogwai [7]
\tan x-5=0
\tan x=5

Now before taking the inverse tangent of both sides, recall that

\tan x=\tan(x\pm\pi)=\tan(x\pm2\pi)=\cdots=\tan(x\pm n\pi)

where n is any integer. This means that when taking the inverse tangent of \tan x, instead of just x, we would end up with

\arctan(\tan x)=\arctan(\tan(x+n\pi))=x\pm n\pi

So after doing so in the equation above, we're left with

x\pm n\pi=\arctan5\implies x=\arctan5\pm n\pi

As n can be any integer, including negative integers, we can simply write

x=\arctan5+n\pi,\,n\in\mathbb Z

Choose the correct conic section to fit the equation. X=1/16y^2
arsen [322]

Hello from MrBillDoesMath!

Answer:

Parabola

Discussion:

The equation is x = (1/16) y^2. Multiply both sides by 16 to get

y^2 = 16x is a parabola that "opens to the right". (Looks like y = x^2 rotated clockwise 90 degrees)

Thank you,

MrB

Talia had a rope that measured 4 2/5 inches. How 1/8 inch pieces of rope can she cut from the larger piece?
spin [16.1K]

Step-by-step answer:

1/8" long piece is not very much.  However, mathematically,

we divide the total length by the length of each piece to get the number of pieces.  So

4 2/5 / (1/8)

= (5*4+2)/5 * (8/1)    [convert to fraction, and division to multiplication

= (22/5) * (8/1)

= 176/5

= 35 pieces with 1/5" left over.

Describe the symmetry of the figure. Identify lines of symmetry, if any. Find the angle and the order of any rotational symmetry
Sophie [7]

Answer:

see below

Step-by-step explanation:

Clearly, if you turn the figure sideways or upside down (rotate 90° or 180°), you do not have the same figure. It has no rotational symmetry.

However, if you reverse it left-to-right, you get exactly the same figure. So, it has line symmetry about a vertical center line.
