Answer:
I'm not 100% correct but this is what I believe proportionality is where k=y/x and k is proportionality constant
$6.57: 3 pounds of orange
y dollar: x pounds of orange
so the proportion
$6.57 y
_____ = _____
3 x
6.57×
_____ = y
3
2.19x = y
so k = 2.19
Answer: -102
Step-by-step explanation: First we do 9-3 = 6, then add -6 which cancels each other out, so all we have left is -102.
Hope this helps! :)
Answer:
the price of the security will be $448.485
Step-by-step explanation:
Annual rate of interest = 3.3%
then Interest rate per quarter (r) will be = 0.033/4
= 0.00825
= 0.825%
now it is given that
Cash flows in the first quarter, C1 = $3.70
Then Present value of perpetuity = C1 /r
= $3.70/ 0.825%
= $448.485
Therefore, the price of the security will be $448.485

that's one combination for f(x) and g(x), off many combinations.
