First, convert watts to kilowatts.
500w/1000= .5 kW per hour
.5*4 hours= 2kwh*365 days= 730 kWh
The answer is 730 kwh per year
- The initial number of bacteria present is equal to 270 bacteria.
- The number of bacteria that will be in the petty dish after 12 hours is 167818 bacteria.
<h3>What is an exponential function?</h3>
An exponential function can be defined as a mathematical function whose values are generated by a constant that is raised to the power of the argument. Mathematically, an exponential function is represented by this formula:
f(x) = eˣ
<h3>How to calculate the initial number of bacteria?</h3>
B(t) = 150e^0.585t
When t = 1, we have:
B(1) = 150e^0.585(1)
B(1) = 150e^0.585
B(1) = 269.25 ≈ 270 bacteria.
<h3>How many bacteria will be in the petty dish after 12 hours?</h3>
B(12) = 150e^0.585(12)
B(12) = 150e^7.02
B(12) = 167817.99 ≈ 167818 bacteria.

Slave traders viewed humans lives as dogs. Because slave traders only wanted humans to work for them and do there dirty work. They did not think anything of there value of life.
If wavelengths of light
from a definite region of the spectrum are engrossed by a material, then the
materials will appear to be the complementary color. If violet light with
wavelength of 400nm is immersed, the material will look yellow. If the material
engrosses blue you will perceive the color orange.
