Answer:
John lost $6841.42.
Step-by-step explanation:
Let's find out how much John paid for the stock he bought. Each share cost $58.02. He bought 120 shares. Multiply the price by the number of shares.
58.02 x 120 = 6962.40
He sold the stock for $120.98 -- a huge loss! (We are not told that the $120.98 is the selling price of one share, so I'm assuming that's what John sold all his shares for.)
Find the difference to see what his loss was.
$6962.40 - $120.98 = $6841.42 LOST!
Given:
The table of values of an exponential function.
To find:
The decay factor of the exponential function.
Solution:
The general form of an exponential function is:
...(i)
Where, a is the initial value and
is the decay factor and
is the growth factor.
The exponential function passes through the point (0,6). Substituting
in (i), we get
![6=ab^0](https://tex.z-dn.net/?f=6%3Dab%5E0)
![6=a(1)](https://tex.z-dn.net/?f=6%3Da%281%29)
![6=a](https://tex.z-dn.net/?f=6%3Da)
The exponential function passes through the point (1,2). Substituting
in (i), we get
![2=6(b)^1](https://tex.z-dn.net/?f=2%3D6%28b%29%5E1)
![2=6b](https://tex.z-dn.net/?f=2%3D6b)
![\dfrac{2}{6}=b](https://tex.z-dn.net/?f=%5Cdfrac%7B2%7D%7B6%7D%3Db)
![\dfrac{1}{3}=b](https://tex.z-dn.net/?f=%5Cdfrac%7B1%7D%7B3%7D%3Db)
Here,
lies between 0 and 1. Therefore, the decay factor of the given exponential function is
.
Hence, the correct option is A.
You have
3/12 = x/16
Multiply by 16
16*(3/12) = x = 4
x = 4
