Answer:
2/3
Step-by-step explanation:
The work done on the box is ...
Fd = (60 N)(10 m) = 600 N·m = 600 J
The amount of energy the box has as a result is ...
KE = 1/2mv² = (1/2)(8 kg)(10 m/s)² = 400 kg·m²/s² = 400 J
The ratio of box energy to energy input is ...
η = (400 J)/(600 J) = 2/3 . . . ≈ 66.7%
Answer:
300 × (1 + 0.10)^n
Step-by-step explanation:
The computation is shown below:
Given that
The population is 300
And, the population would be increased at a rate of 10% each year
So, the exponential growth function to calculate the daily growth rate is
= 300 × (1 + 0.10)^n
Here n represent the number of years or the time period
So, the above show the exponential growth function
Answer:
r = 10
Step-by-step explanation:
Solve for r by simplifying both sides of the equation, then isolating the variable.
