At the beginning of an experiment, a scientist has 348 grams of radioactive goo. After 90 minutes, her sample has decayed to 5.4375 grams.
What is the half-life of the goo in minutes? 22.8
Find a formula for G(t), the amount of goo remaining at time t. G(t) =
348e-031183t
How many grams of goo will remain after 5 minutes?

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°
