There is a formula:
(Pump1 Time * Pump2 Time) / (Pump1 Time + Pump2 Time) = Total Time
Let's say Pump 1 is the old pump
(15 * Pump2 Time) / (15 + Pump2 Time) = 5 Hours
Solving for Pump 2 time
Pump 2 time = (Pump 1 time * Total Time) / (Pump 1 time - Total Time)
Pump 2 time = (15 * 5) / (15 - 5)
Pump2 time = 75 / 10
Pump2 time = 7.5 Hours
and Happy New Year!!!!!
Double Check
(15 * 7.5) / (15 + 7.5) = Total Time
112.5 / 22.5 = 5 Hours Total
Answer:
Ok, we have:
d(t) = 3*t^2 + 5*t - 2.
The first interval is:
(2, 3)
and remember that, for an interval (a,b), the difference quotient is:
D = (f(b) - f(a))/(b -a)
Then in this first interval we have:
So the average rate of change in (2,3) is 20.
now, in (2, 2.5) we have:
So here the rate of change is 9.25
And in the interval (2, 2.1) we have:
So in this interval the rate of change is 1.73
Answer:
Step-by-step explanation:
Given
The above triangle
First, we calculate the length LM using Pythagoras theorem.
Collect like terms
Take positive square root
Solving (a): Sin L
Simplify
Solving (b): tan N
Simplify
Solving (c): cos L
This calculated as:
Simplify
Solving (d): sin N
This is calculated using:
If
Then:
So:
Answer:
sorry sir i really dont even understand
Height x length x width
Therefore
3x10x8 = 240 cm³
