Triangle N Q L has centroid S. Lines are drawn from each point through the centroid to the midpoint of the opposite side to form line segments N R, L P, and Q M. The length of line segment N S is 9 n minus 12 and the length of line segment S R is 3 n. S is the centroid of triangle NQL. What is the length of NR?

step-by-step explanation:

in 1995, potato plants were taken into space aboard the space shuttle columbia.

step-by-step explanation:

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:
