3b.) Nora is buying a used car valued at $22,730. It is expected to depreciate an average of 9.5% each year. Predict the value of Nora's car in
6 years.
Help ??

$12487.86

Step-by-step explanation:

Given data

Cost of car=  $22,730

Rate of decrease= 9.5%

Time= 6 years

We can predict the value by using the exponential decay function'

A= P(1-r)^t

substitute

A= 22730(1-0.095)^6

A= 22730(0.905)^6

A= 22730*0.5494

A=$12487.86

Hence the value will be $12487.86

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.

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.
