The ocean liner Titanic lies under 12500 feet of water at the bottom of the Atlantic Ocean. (The density of water is 62.4 lb/ft3.) (a) What is the water pressure at the Titanic? (Give your answer in both pounds per square foot and pounds per square inch.)
I got 780000 lbs/ft^2 which is equal to about 5416.67 lbs/in^2
(b) What is the total force on a circular porthole (window) of diameter 7 feet standing vertically with its center at the depth of the Titanic?

a)

b)Total force = 30017917.805 lb

Step-by-step explanation:

Depth of titanic = 12500 feet

Density of water =

a)Water pressure at the Titanic =

b)

Set up a integral that gives a total force

Diameter = 7 feet

Rectangular strip area =

Pressure = 62.4(12500-h)

Force =

Force =

Total force =

Total force = 30017917.805 lb

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1

the 1st digit is in the 100s n its 1

step-by-step explanation:

3,589÷18 = 199.389

so the first digit of the quotient is in the 100s n its 1
