A curve in polar coordinates is given by: r=9+3cosθ. Point P is at θ=21π/18 .?
ikadub [295]

Answer:

Step-by-step explanation:

Given that a curve in polar coordinates is given by:

r=9+3cosθ

a) At point P, we have

θ=\frac{21\pi}{18}

Substitute to get

r=9+cos \frac{21\pi}{18}\\=9.3932

b) Cartesian coordinate is

x= rcos \theta=3.6934\\y =r sin \tjeta =8.6365

c) At the origin r =0

when r =0

we have

9+3cos\theta=0\\cos\theta =-3

Since cos cannot take values as -3 it doe snot pass through origin.

If a parallelogram has diagonals that are perpendicular bisectors of each other, what is the most descriptive name for it?
Feliz [49]
Both a rhombus and a rectangle have diagonals that are perpendicular bisectors, but the ones formed in a square are all congruent, so that is probably the most descriptive one.

Please answer and explain.
djyliett [7]

Answer:

x = 13

Step-by-step explanation:

The sum of the exterior angles of a 4 sided polygon is 360

139+ 6x+9x+2x = 360

Combine like terms

139+17x=360

Subtract 139 from each side

17x = 360-139

17x = 221

Divide each side by 17

17x/17 = 221/17

x = 13

What is the slope and y-intercept of y+1=4/3x
Sergio039 [100]

hello

so this equation is written in point slope form: y-y_{1} = m(x-x_{1})

we can solve for y to get the equation into slope intercept form: y=mx+b

y+1=4/3x

subtract 1 from both sides

y=4/3x-1

slope: 4/3

y-intercept: -1

hope this helps

have a nice day :)
