Answer:
Part a) Option d
Part b) Option a
Step-by-step explanation:
Part a
if we look at the options given and the data available
Option a) x^4+9
Putting x= 2 we get (2^4) + 9 =25
Putting x= 3 we get (3^4) + 9 =90 but f(x) =125 so not correct option
Option b) (4^x)+9
Putting x= 2 we get (4^2) + 9 =25
Putting x= 3 we get (4^3) + 9 =73 but f(x) =125 so not correct option
Option c) x^5
Putting x= 2 we get (2^5) =32 but f(x) =25 so not correct option
Option d) 5^x
Putting x= 2 we get (5^2) =25
Putting x= 3 we get (5^3) =125
Putting x= 4 we get (5^4) =625
So Option d is correct.
Part (b)
3(2)^3x
can be solved as:
=3(2^3)^x
=3(8)^x
So, correct option is a

Answer:
Net Proceeds = Selling Price - Total Cost Price
a. Samantha
Total Cost Price;
Bought shares for d dollars and paid 2% commission = d + (d * 2%) = 1.02d
Selling Price;
Sold stock for s dollars and paid flat fee of $11 = s - 11
Net Proceeds = (s - 11) - 1.02d
b. Alex
Total Cost Price;
Bought x dollars worth and paid 1% commission = x + (x * 1%) = 1.01 * x = 1.01x
Selling Price;
Value falls to y and Alex pays 1.25% when he sells = y - (y * 1.25%) = y - 0.0125y = 0.9875y
Net Proceeds = 0.9875y - 1.01x
Answer:
Two points, (0,4) & (8,5)
Step-by-step explanation:
In this equation, we can easily find the first point by looking at the +4 in this equation. This should automatically signal to you that the point is (0,4)
Now, we have to look at the 1/8x in the equation.
This 1/8 means that the slope is 1/8!
Now we use the slope and to rise/run to find our next point
We go up 1 from 4 (this is the rise) to get to 5 on the y-axis
Next, we go over 8 horizontally to get to 8 for your x-axis point.
So therefore, our next point is, (8,5)
You can use this rise/run system infinitely and is very useful
