The change in altitude after 135 seconds was a decrease of 810 meters, that is, -810 meters.
Given that a weather balloon is descending from the atmosphere, and its altitude changes by -6 meters every second, to determine what is the change in altitude after 135 seconds the following calculation must be performed:
- Amount of time x change per second = total change
- 135 x (-6) = X
- -810 = X
Thus, the change in altitude after 135 seconds was a decrease of 810 meters, that is, -810 meters.

Answer:
12,495 is the answer
Step-by-step explanation:
Answer:
Becoming a square will cause in the sides to grow higher and become taller therefore.
Step-by-step explanation:
The center is at origin O(0,0).
If it contains the point, P(-8,6), then the radius r is, by Pythagoras theorem,
r=sqrt((-8)^2+6^2)=10
The general equation of a circle at centre (xc,yc) with radius r is given by
(x-xc)^2+(y-yc)^2=r^2
Substituting r=10, (xc,yc)=(0,0)
the resulting equation is therefore
(x-0)^2+(y-0)^2=10^2
or simply
x^2+y^2=100
