Considering the surface area of the spherical ballon, it will take 7 seconds for the the balloon to fully inflate.
<h3>What is the surface area of a sphere?</h3>
The surface area of a sphere of radius r is given by:

In this problem, the surface area is of
cm², hence the radius in cm is found as follows:





r = 14 cm.
The radius start at 0 cm, inflating at a rate of 2 cm/s, hence it will take 7 seconds for the the balloon to fully inflate, as 14 cm/(2 cm/s) = 7 s.

Answer:
y= -2x-9
Step-by-step explanation:
x would move left or right, and up and down is y
left or down are negative and up or right are positive
1 meter is 3.3 ft.....so 70 meters is (70 * 3.3) = 231 ft.....so ft per second is 231 ft per second
at 2 seconds.....231 * 2 = 462 ft
All the other stuff, east/west, doesn't matter.
He drives 3 miles north, then later on he drives 4 more miles north:
3 + 4 = 7
The dog show is 7 miles north of his home.
