Answer:
The interval of decrease is 0 ≤ x ≤ 1.25
Step-by-step explanation:
First, we have to find the point where it changes from increasing to decreasing or decreasing to increasing.
The graph shows that there is a decrease before 1.25 h, and it increases after 1.25 h also.
We can further prove that 1.25 is the point of change when we enter 1.25 in place of t in the given equation
d(1.25) = 40|1.25 - 1.25| = 0
We see that the graph is decreasing before 1.25, so the interval will have to end at 1.25.
We also see that there is no increase before 1.25, so we can make the interval begin at 0
Answer:
Answer:
The student council made more snow cones per hour than the parent volunteers.
Explanation:
To find the number of snow cones made per hour:
XXX
Divide the number of snow cones made
XXX
by the number of hours spent making snow cones.
Parent volunteers
XXX
Number of snow cones:
120
XXX
Number of hours spent making snow cones:
5
Number of snow cones per hour:
120
÷
5
=
24
Student council
XXX
Number of snow cones:
100
XXX
Number of hours spent making snow cones:
4
Number of snow cones per hour:
100
÷
4
=
25
Since the student council made
25
snow cones per hour and the parent volunteers only made
24
snow cones per hour:
the student council made more snow cones per hour.
Step-by-step explanation:
I think its just 3
<span>Just t/3.</span>
The vertical distance will be given by:
sin θ=opposite/hypotenuse
but
θ=6°
opposite=x
hypotenuse=120 ft
thus
sin 6=x/120
x=120 sin 6
x=12.54 ft
thus the hiker's change of position is 12.54 ft
