Question

Under water, pressure increases 4.3 pounds per square inch (psi) for every 10 feet you descend. This is represented by the equation p = 0.43d + 14.7, where p is the psi and d is the depth in ft. Find the pressure at 200 feet. (Points : 2)
215.13 psi
860 psi
100.7 psi

Answer 1

p(200) =

Answer 2

p = 0.43d + 14.7
p = 0.43 X (200) + 14.7
p = 86 + 14.7

p = 100.7

Answer 3

@DanJS Right?

Answer 4

yep

Answer 5

Perfect thanks:)

Answer 6

Don't know, they might have a question, What is the pressure from the Air or something, P(0)= 14.7 psi , at sea level

Answer 7

oh okay
