5. evaluate the function f (x) = 4 • 7x for x = -1 and x = 2. show your work.

you in advance!

f(-1) = -28 f(2) = 56

Step-by-step explanation:

f(-1) = 4 * 7(-1)

f(-1) =4* -7

f(-1) = -28

f(2) =4 * 7(2)

f(2) =4* 14

f(2) = 56

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°
