Apopulation of 430 animals decreases at an annual rate of 21% find the multiplier for the rate of exponential decay

0.79

Step-by-step explanation:

We have been given that a population of 430 animals decreases at an annual rate of 21%. We are asked to find the multiplier for the rate of exponential decay.

We know that an exponential decay function is in form , where,

a = Initial value,

r = Decay rate in decimal form.

Let us convert 21% in decimal form as:

Upon substituting our given values, we will get:

Therefore, the multiplier for the rate of exponential decay is 0.79.

40 x 50 = 2000

step-by-step explanation:

1) the property is   ixi = a ⇔x = a   o x = -a

4(x-5)+3= 15⇒4x-20+3 = 15⇒4x-17= 15⇒4x = 15+17⇒4x = 32⇒x =32/4= 8

4(x-5) +3= -15⇒4x-20 +3 = -15⇒4x-17= -15⇒4x =-15+17⇒4x = 2⇒x =2/4= 1/2

the values are x =8 and x = 0,5
