Dan wrote (2x10^6)+(3x10^4)+(5x10^3)+4 for the expanded form of two millions , three hundred fifty thousand, four. what error did he make in the expanded form? what is the standard form of the number?

Part 1) Dan wrote in expanded form two millions thirty five thousand, four instead of  two millions , three hundred fifty thousand, four

Part 2) The standard for of the number is

Step-by-step explanation:

we have

The number two millions , three hundred fifty thousand, four

we know that

Dan Wrote

The number that Dan wrote is two millions thirty five thousand, four

The correct number in expanded form is

The standard for of the number is

answer: a.   one is a factor of every whole number since every number is divisible by itself.

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
