What is the decay factor in the exponential decay function y=a (1-r) t
MrRissso [65]

Answer:

in this form, the "-r" would cause the result to decrease

I assume that the answer is "r"

if r = .1 (10 %) then 1-.1 = .9

if you have 100 items then y = 100(.9)^1 = 90

the total decreased by 10% ... y = 100(.9)^2 after 2 time periods

20% of the rose Annette picked from a rose garden were red if she picked 10 red roses how many roses did she pick from the garde
horrorfan [7]

Answer:

Option A

Annette picked  50 roses  from the garden

Step-by-step explanation:

Let us understand the problem, designating letters to represent unknown quantities.

Let the total number of roses = x

20% of the roses were red means that 20% of x = red

Since the number of red roses = 10,

we will have that 20% of x = 10

mathematically, we will have

\frac{20}{100} \times x = 10\\x= \frac{1000}{20}= 50

hence, Annette picked  50 roses  from the garden
