1. Identify each situation in which a quantity grows or decays by a constant percent rate per unit interval. A. The number of ca
zvonat [6]

Answer:

Step-by-step explanation:

1) For each situation to grow or decay by a constant percent rate, it must be exponential. Therefore, the correct examples are

A. The number of cars sold doubles every year. It is a 200% growth every year.

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

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) this is a case of exponential decay. The expression for exponential decay is

y = b(1 - r)^t

y = final value

b = initial value

r = decay rate

t = time

Given that

r = 10% = 10/100 = 0.1

b = 50 kilograms

y = W kilograms

The relationship is

W = 50(1 - 0.1)^t

W = 50(0.9)^t

Help me please ^^ much appreciated
Reil [10]

Answer:

C

Step-by-step explanation:

Using the sine ratio in the right triangle.

sinC = \frac{opposite}{hypotenuse} = \frac{AB}{BC} = \frac{16}{28} , thus

∠ C = sin^{-1} (\frac{16}{28} ) ≈ 34.85° ( to 2 dec. places )
