If sec (θ) < 0 and tan (θ) < 0, what quadrant does the angle theta lie.

they can both be solutions depends on the equation

step-by-step explanation:

what is the equation? ?

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:

d. you cannot tell because there are no values shown.
