Given that center is at origin that is (0,0)
x intercepts are + 10 and -10 so the right most and left most points are ( 10,0) and (-10,0)
the y intercepts are + 5 and -5 so the top most point is (0,5 ) and bottom most point is ( 0,-5 )
now we find half of major length ( which is along x axis here )= (10+10 )/2=10
and half of minor length ( which is along y axis here )= (5+5)/2 = 5
hence equation of ellipse : ( X - 0 ) ^2 + ( Y -0 )^2
-------------- -----------
10 ^2 5 ^2
Answer:
7 1/2 days
Step-by-step explanation:
The carpenter can do 1/5 of the work in 1 day. The assistant, who takes 'a' days to do the work, can do 1/a of the work in 1 day. Together, they can do 1/3 of the work in 1 day:
1/5 + 1/a = 1/3
1/a = 1/3 -1/5 = 2/15
a = 1/(2/15) = 15/2 = 7.5
The assistant takes 7.5 days to do the work alone.
Answer:
x=3, y=5
Step-by-step explanation:
To find x:
Because opposite sides of a parallelogram are congruent, we can set up the equation 2x+5=12x-25. Solving the equation will show that x=3.
To find y:
Using the same method as x, we can find that y=5.
