A diver, when submerged in sea waters, suffers from increased pressure as he sinks. The pressure increase is described by a graph that passes through points (0, 2) and (20, 4), in atmosphere, as a function of depth, in meters. With this, determine the equation that expresses the pressure, in atmosphere, as a function of depth, in meters. And check what is the pressure suffered by the diver at 22 m depth?

Equation: y = 1/10x + 2

Pressure at 22 m: 4.2 atm

Step-by-step explanation:

Step 1: Find equation

m = (4 - 2)/(20 - 0)

m = 2/20

m = 1/10

y = 1/10x + b

y = 1/10x + 2

Step 2: Find pressure at 22 meters

y = 1/10(22) + 2

y = 2.2 + 2

y = 4.2

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
