If f(x)=4^x-8 and g(x) =5x+6, find (f+g)(x)

C

Step-by-step explanation:

(f + g)(x) = f(x) + g(x), then

f(x) + g(x)

= - 8 + 5x + 6 ← collect like terms

= + 5x - 2 → C

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°
