Answer:
Step-by-step explanation:
Given the following :
Laps - - - - - - - - 5 - - - 6 - - - 7 - - - 8 - - - 9
Total time - - - 25 - - 28 - - 29 - - 30 - - 32
Using online graphing tool:
The y - axis named dependent variable represents the total time taken.
The x-axis, represents the number of laps.
The equation of the trend line attached to the plot is in the form :
y = mx + c
y = 1.6x + 17.6
Where y = total time taken
x = number of laps
m = 1.6 = gradient of the line (change in y / change in x)
C = 17.6 = intercept (whee the trndline intersects the y-axis).
Answer:
Substitution
Step-by-step explanation:
The subtraction property of equality is when you subtract from both sides, they will still be equal. The multiplication property is the same thing but with multiplication.
Answer:
multiply!!
Step-by-step explanation:
just multiply for number 4 :)
Yes its true because they would be called intersecting lines
Answer:
dh/dt = 2/3*π ft/min
Step-by-step explanation:
We have a right circular cylinder, and water is pouring at a constant rate, we must expect the height of the water will rise a constant rate, therefore it does not matter the height
V(c) = π*r²*h ⇒ V(c) = π*(3)²*h ⇒ V(c) =9*π*h
DV(c)/dh = 9*π
DV(c)/dh = DV(c)/dt * dt/ dh ⇒ 9*π = DV(c)/dt * dt/ dh
dh/dt = DV(c)/dt / 9*π
DV(c)/dt = 6 ft³/m ( from problem statement )
Then
dh/dt = 6/9*π ft/min
dh/dt = 2/3*π ft/min
