Identify the exponential function that correctly fits the situation below. the size of a rainforest is currently decreasing at a rate of 17% per year. if there are currently 230,000 square miles of rainforest, then about how many square miles of rainforest will there be in t years? a. f = 230,000(0.17)t b. f = 230,000(0.83)t c. f = 230,000(1.17)t d. f = 230,000(1.83)t

answer: the correct answer is -32

step-by-step explanation:

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.
