Where is the midpoint located if a line segment has the endpoints of (-4, -2) and (-1, -6)? * A. (2, -10)
B. (-2.5, -4)
C. (-3, -3.5)
D. (-1.5, 2)

B. (-2.5, -4)

Step-by-step explanation

x = 1/2(x^1 + x ^2)

x = 1/2(-4 + -1)

x = 1/2(-5)

x = -2.5

y = 1/2(y^1 + y^2)

y = 1/2(-2 + -6)

y = 1/2(-8)

y = -4

(-2.5, -4)

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:
