A small town has 5 police officers. When a radio dispatcher receives a call, depending on the nature of the situation, no officer, one officer, two officers, three officers, four officers, or all five officers can be sent. How many different ways can the dispatcher send the police officers to the scene of the caller?

N = 32 ways

the dispatcher can send the police officers to the scene of the caller in 32 ways.

Step-by-step explanation:

Given;

Total number of officers = 5

The total number of ways the dispatcher can send the police officers is the sum of the number of ways of sending each of no officer, one officer, two officers, three officers, four officers, or all five officers.

N = 5P0 + 5P1 + 5P2 + 5P3 + 5P4 + 5P5

N = 1 + 5 + 10 +10 + 5 + 1 = 32

N = 32 ways

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:
