The general equation for a circle with center (a,b) and squared radius k is
Here we have
and the constant is fixed by substituting in the point we know (x,y)=(3,-5)
Answer:
Answer:
Mixed number - 2 8/15
decimal - 2.53
Step-by-step explanation:
3+9+26=38
denominator is 15
38/15 convert to a mixed number =
2 8/15 as a decimal is 2.53
X = 3 that is you x intercept
y = 2 that is your y intercept
Take the vector u = <ux, uy> = <4, 3>.
Find the magnitude of u:
||u|| = sqrt[ (ux)^2 + (uy)^2]
||u|| = sqrt[ 4^2 + 3^2 ]
||u|| = sqrt[ 16 + 9 ]
||u|| = sqrt[ 25 ]
||u|| = 5
To find the unit vector in the direction of u, and also with the same sign, just divide each coordinate of u by ||u||. So the vector you are looking for is
u/||u||
u * (1/||u||)
= <4, 3> * (1/5)
= <4/5, 3/5>
and there it is.
Writing it in component form:
= (4/5) * i + (3/5) * j
I hope this helps. =)
it’s a because you need all those figures to make it happen
