The significance of "b" in exponential function
An exponential function is represented as:
In the above equation, parameter "b" is the rate of the function
In other words, the constant multiplier of the function.
Take for instance;
By comparison:
Another instance is:
By comparison
<u>Other significance of parameter b are:</u>
If 
then b represents a growth factor
If 
the b represents the factor of decay
i.e. b is never 0
Profit made by jeweler from buying and reselling ounces of gold is 140.89 per ounce
<u>Solution:</u>
Given that
Price at which jeweler buy gold = 1235.55 per ounce
Price at which jeweler resells gold = 1376.44 per ounce
We need to calculate profit.
Buying price of 1 ounce of gold = 1235.55
Reselling price of 1 ounce of gold = 1376.44
<em>Profit = Reselling price – buying price</em>
So profit on 1 ounce of gold = 1376.44 – 1235.55 = 140.89
Hence profit made by Buying and Selling gold will be 140.89 per ounce
Answer:
- 43
Step-by-step explanation:
Expression: (3m+2n−6) and (−4−6m+7n)
n= -2 and m=5
Before inserting the values, let's add both expressions.
(3m+2n−6) + (−4−6m+7n)
3m+2n−6 −4 − 6m + 7n
-3m + 9n - 10
Inserting the values;
-3(5) + 9(-2) - 10
-15 - 18 -10
- 43
1) 3x+y+z=4
2) 2x+2y+3z=3
3) x+3y+2z = 5
1)*2 6x + 2y + 2z = 8
2) 2x + 2y +3z = 3
- __________________
4x - z = 5
2)*3 6x + 6y + 9z = 9
3)*2 2x + 6y + 4z = 10

4x+5z = -1
4x - z =5
- ________
6z = -6
<u>z = -1
</u><u /><u>
</u>If z=-1,
4x -(-1) =5
4x = 5-1
x = 4/4
<u>x=1</u>
3x+y+z=4
3(1)+y+(-1)=4
3+y-1=4
<u>y=2
So z=-1, x=1, y=2</u>
