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.
Answer:
C.
Step-by-step explanation:
The line that is a perpendicular bisector of the segment connecting the two points.
Use Pythagorean theorem
a^2 + b^2 = c^2
You know b = 7, c = 16
Plug in the values
a^2 + 7^2 = 16^2
a^2 + 49 = 256
a^2 = 207
a = 14.38749
Round to nearest tenth
Solution: a = 14.4 in.
Answer:
a ≤ -1
Step-by-step explanation:
3 ≤ 4 – a
a ≤ 3 - 4
a ≤ -1
Answer:
15 Poses
Step-by-step explanation:
SInce he can teach 30 poses in 60 minutes and if the class time is cut by half then the poses are cut by half. Look below.
Minutes : 60/2 = 30 minutes
Poses : 30/2 = 15 poses
