Pentagon K'L'M'N'P' is a rotation of KLMNP counterclockwise about the origin through an angle of 90∘. Which of the following is an algebraic representation of this rotation? Group of answer choices

(x, y)⟶(−y, x)

(x, y)⟶(x,−y)

(x, y)⟶(−x, y)

(x, y)⟶(−x,−y)

the answer is b 1/10

answer: its the third option.

step-by-step explanation:

i just took the test.

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:
