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:
(3,13)
Step-by-step explanation:
so, you would add 3 to the y value
the point would be (3,13)
The Planck–Einstein relation

gives that E, the photon energy, is equal to h, Planck's constant, times <span>ν</span>, the frequency.
We can solve the equation in terms of frequency to get

We substitute our given energy,

, and Planck's constant,

.
