On January 1, the company purchased equipment that cost $10,000. The equipment is expected to be worth about (or has a salvage value of) $1,000 at the end of its useful life in five years. The company uses straight-line depreciation. It has not recorded any adjustments relating to this equipment during the current year

rounding to the nearest thousandth would be 452,000

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:
