Distance formula : d = sqrt (x2 - x1)^2 + (y2 - y1)^2
(11,4)(10,5)
d = sqrt (10 - 11)^2 + (5 - 4)^2
d = sqrt (-1^2) + (1^2)
d = sqrt (1 + 1)
d = sqrt 2
d = 1.41 <===
Answer:
x=12
Step-by-step explanation:
3x=2x+12
3x-2x=12
x=12
Gravity pulls you to earth at velocity of 9.8 m/s. In the first 40 seconds, Jason would fall (9.8) x (40) = 392 meters.
We can set this up as a proportion.
Since 2 is proportional to 1000, then 4 is proportional to "doctors surveyed".

where d is the doctors surveyed.
Cross multiply.
2d = 4000
d=2000
2000 doctors were surveyed.
