Kayla was at the surface of a swimming pool and recorded the following two measurements, in feet, on a number line: −9, which represents the depth of water in the swimming pool +10, which represents the height of the slide at the pool part a: what does 0 represent in this situation? (3 points) part b: describe the height of the slide in relation to 0 in the situation. (3 points) part c: kayla held a pole in the swimming pool. the bottom of the pole was at a depth of 3 feet. how should kayla mark the level of the bottom of the pole on the number line? explain how you determined this. (4 points)

Part A:

0 = the surface of the swimming pool

Part B:

Since the height of the slide is measured at +10 feet, then this means

that the top of the slide is 10 feet above the surface of the water (0) in the swimming pool.

Part C:

Since 3 feet of the pole was put in the water, then Kayla should mark the of the bottom of the pole as -3 feet.

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
