Hi can you help me please? Consider a line segment connecting Felina's house to Zaire's house, and another line segment connecting Zaires house to Bilmal's house. What is the relationship between the two line segments?

A. They form an acute angle
B. They form an obtuse angle
C. They are parallel
D. They are perpendicular

if you was gonna solve for a, a is a   < -12

but which class are u may know that first

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:
