Answer:
5. independent variable hours (h); dependent variable; total cost
6. t= 10h + $4.50
Step-by-step explanation:
The final result in dependent on how many hours he uses the boat.
Ok, so remember that the derivitive of the position function is the velocty function and the derivitive of the velocity function is the accceleration function
x(t) is the positon function
so just take the derivitive of 3t/π +cos(t) twice
first derivitive is 3/π-sin(t)
2nd derivitive is -cos(t)
a(t)=-cos(t)
on the interval [π/2,5π/2) where does -cos(t)=1? or where does cos(t)=-1?
at t=π
so now plug that in for t in the position function to find the position at time t=π
x(π)=3(π)/π+cos(π)
x(π)=3-1
x(π)=2
so the position is 2
ok, that graph is the first derivitive of f(x)
the function f(x) is increaseing when the slope is positive
it is concave up when the 2nd derivitive of f(x) is positive
we are given f'(x), the derivitive of f(x)
we want to find where it is increasing AND where it is concave down
it is increasing when the derivitive is positive, so just find where the graph is positive (that's about from -2 to 4)
it is concave down when the second derivitive (aka derivitive of the first derivitive aka slope of the first derivitive) is negative
where is the slope negative?
from about x=0 to x=2
and that's in our range of being increasing
so the interval is (0,2)
Answer: 
Step-by-step explanation:
The equation of the line in Slope-Intercept form is:
Where "m" is the slope and "b" is the y-intercept.
You need to find slope of the line with the formula:
Pick to points of the given line. You can choose the point (60,3) and the point (30,2).
Then, substituting into the formula:
You can observe in the graph that the line intercepts the y-axis at the point (0,1), therefore "b" is:
Substituting the slope and the y-intercept found into , you get the equation of this line:
Where "y" represents the Height (1,000 ft) and "x" represents the Time in seconds.
