Plz help me if u do u a good person

f(x)=-2x+9

f(4)+3=?

let x equal to 4

f(4)=-2(4)+8

f(4)=-8+9=+1

f(4)=1

then add 3 to f(4)

f(4)+3=1+3

f(4)+3=4

and he need f(4)+3 so the answer is

4

that's it

40 is the final : )

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
