Expand the expression using the binomial theorem and pascal's triangle: (3x-1)^3

answer:

resultant force will act on 65° n of w.

step-by-step explanation:

as given in the question one bulldozer exerts force of 1250 pounds in western direction and 2650 pounds in northern direction and we have to find angle a which is an angle between 1250 pounds of force and resultant force f.

therefore tan a= force on north direction/ force on west direction = 2650/1250 = 2.12

⇒

a = 64.75

a = 65° north of west.

answer:

4.32

step-by-step explanation:

18% x 24 = 4.32

answer:

a(p(t))     =113.04 t^2

a (p(8))   =7234.56

step-by-step explanation:

p(t) = 6t

a (p) = 3.14 p^2

so a(p(t)) = means we   put p(t) in the function for a

                = 3.14 p^2

                = 3.14 (6t) ^2

                  = 3.14 (36t^2)

    a(p(t))     =113.04 t^2

let t=8    

a (p(8)) = 113.04 (8)^2

            = 113.04(64)

              =7234.56
