The functions s and t are defined as follows. s(x) = -2x+2
t(x) = 2x² - 1
Find the value of s (t(2)).
s(t(2)) =
, I got -12 but I’m not sure.

Below in bold.

Step-by-step explanation:

(s + t)x = s(x) + t(x) =  6x + 2x + 2

= 8x + 2.

(s - t)x = s(x) - t(x) =  6x - (2x + 2)

=  4x - 2.

(s x t) = s(x) * (t(x) =  6x(2x + 2)

= 12x^2 + 12x.

Step-by-step explanation:

intensity of the vector is v= √37 ≈ 6.08 units and make angle ∡α ≈ 9.46° with east direction

step-by-step explanation:

required vector is consists of the two componentsvx= 2+4=6 units   and vy= 1 unit and vx ⊥ vywe will use pythagorian theorem to find intensity of the vector vv∧2 = vx∧2 + vy∧2 => v = √vx∧2 + vy∧2 = √6∧2 + 1∧2 = √36+1 = √37 ≈ 6.08 unitsthe angle ∡α between vector and east direction we wil find with tanαtanα = 1/6 => α = arc tanα = arc 1/6 => α ≈ 9.46°

hope this
