What is the explicit for f(0) =100 f(n) f(n-1)+20

a² + b²= c²

24² + 7² = c²

c= 25

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:

i think it is c hope that
