Identify each situation in which a quantity grows or decays by a constant percent rate per unit interval

A. The number of cars sold doubles every year.

B. The value of a boat decreases by $3000 every 2 years.

C. The number of visitors at the Zoo increases by 1,000 each year.

D. Each time you start a car engine the remaining engine life decreases by 0.0075%

E. The number of people creating cat videos increases by 15% percent every year.

F. Computer technology increases by a factor of 3 every five years.

2. A block of ice weighing 50 kilograms begins to melt. Each hour the block of ice loses 10% of its weight. Let W be the weight in kilograms after melting for t hours. Describe the relationship between w and t?

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.

c: y > - 1/6x + 1

step-by-step explanation:

dashed line - meaning this < or > also not equal

solid line - meaning this < or > also equal

your answer is c because y > means up & it's shaded up, but y < means down

hope this ! : )

answer: the answer is d
