PLEASE DO BOTH Write the quadratic regression equation that models the data. Let x = depth below the surface and let y = soil density. Round all numbers to the nearest hundredth.

Use the equation to estimate the soil density of a sample at a depth of 15 m. Show your work.

answer:

3 bags of apples and 2 bags of oranges.

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:

you could deduce the conclusion directly using the facts pertaining to the specific situation.

hope this .
