A curve has the equation y= x + 6/x^2
-> Show that x [d^2y/dx^2] + 3 [dy/dx]= 3

1. perpendicular

2. parallel

3. perpendicular

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:

answer:

c) the x-coordinate of the center of the circle increases by 3
