What is the x-coordinate of the point that divides the directed line segment from J to K into a ratio of 2:5? x = (StartFraction m Over m + n EndFraction) (x 2 minus x 1) + x 1

x = -2

Step-by-step explanation:

The image and whole question is attached.

The end point are:

J(-6, -2)

K(8, -9)

We need to divide the segment in ratio 2:5

The formula is:

m and n are the ratio, hence

m = 2

n = 5

x_2 = 8

x_1 = -6

Substituting, we get the x-coordinate:

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:
