Answer:
x=1
Step-by-step explanation:
14+2x+7=9x
2x-9x=7-14
-7x= -7
x= -7/-7
x=1
Side GF^2 = 144 -100
Side GF^2 = 44
Side GF = 2*sqrt(11)
Side GF = 6.6332
Perimeter = 6.6 + 10 + 12
Perimeter = 28.6
Answer is 29 units
Radius, r = 3
The equation of a sphere entered at the origin in cartesian coordinates is
x^2 + y^2 + z^2 = r^2
That in spherical coordinates is:
x = rcos(theta)*sin(phi)
y= r sin(theta)*sin(phi)
z = rcos(phi)
where you can make u = r cos(phi) to obtain the parametrical equations
x = √[r^2 - u^2] cos(theta)
y = √[r^2 - u^2] sin (theta)
z = u
where theta goes from 0 to 2π and u goes from -r to r.
In our case r = 3, so the parametrical equations are:
Answer:
x = √[9 - u^2] cos(theta)
y = √[9 - u^2] sin (theta)
z = u
