Jeff and jason are diving near a corral reef in the ocean. jason is swimming along the bottom of the ocean floor 188.82 feet from the boat's anchor which lies directly below the boat at a depth of 172.22 feet. if jeff is 20 feet directly above jason, how far is jeff from the boat? (round to nearest tenth)

Jason is below the sea anchor, which is below the boat.

Add the two depth measurements: 188.82 + 172.22 = 361.04

Jeff is 20 feet above Jason

361.04 - 20 = 341.04

Jeff is ~341 feet from the boat.

hello,

as we don't know if g(x) is continue,

answer b

f(x)=2x²-8x+1=2(x²-4x+4)+1-8=2(x-2)²-7

vertex is (2,-7) ( a minimum since coefficient of x² is > 0)

the speed is   miles per hour > is false

step-by-step explanation:

we know that  

a relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or

in a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

the graph shown in the figure represent a direct variation

the slope of the line represent the speed

for the point

substitute the values of x and y

the linear equation is equal to

statements

case a) it takes hours to go miles

the statement is true

because

substitute

for

find the value of y in the linear equation

> is correct

case b) the speed is   miles per hour

the statement is false

because the speed is

case c) the unit rate for the trip is

the statement is true

because the speed is equal to the slope of the linear equation

case d) it took minutes to go the first miles

the statement is true

because

substitute

for

find the value of y in the linear equation

> is correct
