4* In the diagram shown, the vertices of ADEF are the midpoints of the
sides of equilateral triangle ABC, and the perimeter of AABC is 36 cm.
What is the length, in centimeters, of EF?
1.) 4
2.) 12
3) 18
4.) 6

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value

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:

38.6°

step-by-step explanation:

resultant is 10 pound

smaller force = 8 pound

angle formed = tan⁻¹(

                        =tan⁻¹(

                          =tan⁻¹(0.8)

                        =38.6°
