It looks like
(If the limits are in the wrong order, just multiply the result by -1)
Split the integral at an arbitrary value between
and
, and write
as
Then by the FTC,
In y=kx , subst. -30 for x and 3 for y. Then solve the resulting equation for k:
3 = k(-30).
Dividing both sides by -30, we get:
-3/30 = -1/10 = k
The constant of proportionality is k = -1/10.
I believe the patter is going up like 1,2,3,4 so next I would say would be 5
Answer:
B ±sqrt((y-k)/a ) + h= x
Step-by-step explanation:
y=a(x-h)^2+k
Subtract k from each side
y-k = a(x-h)^2+k-k
y-k = a(x-h)^2
Divide by a
(y-k)/a = a(x-h)^2/a
(y-k)/a = (x-h)^2
Take the square root of each side
±sqrt((y-k)/a )= sqrt((x-h)^2)
±sqrt((y-k)/a )= (x-h)
Add h to each side
±sqrt((y-k)/a ) + h= (x-h+h)
±sqrt((y-k)/a ) + h= x
