You work in a chemical lab. last quarter, you successfully completed an average of about 5 chemical analyses per day. this quarter, you have increased this average to about 8 per day. what is you percentage increase

percentage increase is 60%

Step-by-step explanation:

given data

average = 5 per day

increase average = 8 per day

to find out

percentage increase

solution

we know starting initially average is 5 per day and increase about 9 per day

so percentage increase =( increase average - average ) / average × 100   1

put here value

percentage increase = ( increase average - average ) / average × 100

percentage increase = ( 8 - 5 ) / 5 × 100

percentage increase = 60

so percentage increase is 60%

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

hey seth! : )

i’m not 100% sure, but i think it’s b

hope this ya : p

miss u!
