Aland owner is planning to build a fenced-in, rectangular patio behind his garage, using his garage as one of the "walls." he
wants to maximize the area using 80 feet of fencing. the quadratic function a(z) = x(80 – 22) gives the area of the
patio, where x is the width of one side. find the maximum area of the patio.

step-by-step explanation:

divide 13.5 by 9 to get the scale factor. it equals 1.5

2 * 1.5 = 3

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:
