Answer:
x²+(y-5)²=25
Step-by-step explanation:
To convert polar into rectagular
![->r=\sqrt{x^2+y^2} =>r^2=x^2+y^2\\](https://tex.z-dn.net/?f=-%3Er%3D%5Csqrt%7Bx%5E2%2By%5E2%7D%20%3D%3Er%5E2%3Dx%5E2%2By%5E2%5C%5C)
also, y=rsin θ => sin θ=y/r
r= 10sinθ
r=
=> r²=10y
therefore, x²+y²-10y=0
By completing the squares on y²-10y gives
x²+(y-5)²=25
which is the equation of the circle.
This is the Cartesian equation of a circle with center (
0,
5)
and radius, r=5
If you would like to know what will the time be 3 hours and 15 minutes later, you can calculate this using the following steps:
11:45 a.m. + 3 hours and 15 minutes = 12:00 p.m. + 3 hours = 15:00 p.m. = 3:00 p.m.
The correct result would be 3:00 p.m.
Answer:
\left(-32ux+19u^2x^3-12u^6x^7\right)\:divided\:by\:\left(-4u^2x^3\right)
Step-by-step explanation:
Factor the numerator and denominator and cancel the common factors.
\frac{8}{ux^2}\:-\frac{19}{4}+3u^4x^4
Answer:
false
Step-by-step explanation:
This is a solution to the first equation because
5+-9=-4
-4=-4
however, if you plug it into the next equation, it becomes false.
5--9=4
14=4
this does not make sense.
