PLEASE HELPP ASAP PLZ!

Step-by-step explanation:

-1.875

Since there are 3 digits after decimal point, we will omit the decimal point by putting a 1000 in the denominator ( 1000 has 3 zeroes just as there were 3 digits after the decimal point.)

So, It'll become:

=    [Dividing by 125 as it is it's GCF]

=

Hope this helped!

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

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
