Answer:
The number of fringes at 
is given as 20.
Step-by-step explanation:
Question
A Galapagos cactus finch population increases by half every decade. The number of finches is modeled by the expression
,
where d is the number of decades after the population was measured. Evaluate the expression for d = −2
Given :
The number of finches is modeled by the expression :
⇒ 
where 
is the number of decades after the population was measured.
To evaluate the expression for d=-2
Solution:
In order to evaluate the given expression to find the number of finches at , we will plugin 
for in the expression and simplify it.
Plugging in in the expression:
⇒ 
Using negative exponent property. [
⇒ 
⇒ 
⇒ 
(Answer)
Thus, the number of fringes at is given as 20.
This means the number of fringes two decades ago was 20.
P = 7n + 20
consider the results of figure to perimeter
1 → 27
2 → 34
3 → 41
the difference between perimeters is 41 - 34 = 34 - 27 = 7
multiplying the figure number by the difference gives
1 × 7 = 7 ← require 27 thus add 20
2 × 7 = 14 ← require 34 thus add 20
3 × 7 = 21 ← require 41 thus add 20
Hence the required equation is
P = 7n + 20
Answer: They played 25 games
Step-by-step explanation: If they had 15 wins and the total games they played is 60% then they lost 10 times and they played 25 games because if you divide 15 by 60 you get 0.25 so they played 25 games.
