Question 168835This question is from textbook California Mathematics
: The temperature was 15C at noon when the cold front entered the area. The temperature began dropping at a rate of 7C per hour for the next several hours. Write an expression for what the temperature was after h hours. Evaluate the expression to find the temperature after 4 hours.
A submarine is 10 feet below sea level. it dives 8 feet per second. write an expression to describe the submarines position after s seconds. evaluate the expression to find the submarines position after 30 seconds. This question is from textbook California Mathematics
You can put this solution on YOUR website! The temperature was 15C at noon when the cold front entered the area. The temperature began dropping at a rate of 7C per hour for the next several hours. Write an expression for what the temperature was after h hours. Evaluate the expression to find the temperature after 4 hours.
Temp = -7h + 15
T(4) = -7(4) + 15 = -13C
============================
A submarine is 10 feet below sea level. it dives 8 feet per second. write an expression to describe the submarines position after s seconds. evaluate the expression to find the submarines position after 30 seconds.
P(t) = -8t - 10
P(30) = -8*30 - 10
P(30) = -250 ft
======================

You can put this solution on YOUR website! let h be the number of hours and C the temperature after h hours
15-7h=C evaluating h=4 we have 15-7(4)=-13Celcius
::::::::::
let s be the number of seconds and D be the depth after s seconds
10+8s=D...evaluating s=30 we have 10+8(30)=250 ft deep
