Moving the decimal point to the right 4 places in a number is the same as multiplying by 10-4 multiplying by 104 multiplying by 10 multiplying by 4

multiplying by option(2)

Step-by-step explanation:

We have to shift the decimal to right side

Let us consider an example,

4×10=40

4×100=400

4×1000= 4000

4×10000=40000

After multiplying, each time  decimal is shifted to right side

Since, we have to shift the decimal to right side than we have to multiply by 10000 i.e,

Hence, the correct answer is  

answer:   the paragraph proof is mentioned below.

step-by-step explanation:

given: in a δxwy where

such that, ∠wzx ≅ ∠yzx and zw≅zy

we have to prove that: segment zx is a perpendicular bisector of segment wy.

prove: since, zw≅zy ⇒ ∠wzy is a supplementary angle.

then, ∠wzy= 180°

⇒∠wzx + ∠yzx = 180° ( because xz divides ∠wzy into two parts)

but, ∠wzx ≅ ∠yzx ( given)

⇒∠wzy+∠wzy=180° ( by substitution)

⇒2∠wzy=180°

⇒∠wzy=90°

⇒∠wzy=∠yzx =90°

therefore, xz⊥wy where wz=zy

⇒zx is a perpendicular bisector of wy.
