Answer:
Domain: {1,2,4}
Step-by-step explanation:
The domain is the input values
We normally list the value in order from smallest to largest and only list the values one time if they appear more than once
Domain: {1,2,4}
The answer is T=PV/nR
Hope this helps!
Answer:
$569.80
Step-by-step explanation:
We can use the simple interest formula for this:
<em>P = initial balance
</em>
<em>r = annual interest rate
</em>
<em>t = time
</em>
<em />
First, change 7.2% into its decimal form:
7.2% -> 
-> 0.072
Next, since we are calculating for 6 months (1/2 of a year), the annual interest rate will be 0.5. Now, plug in the values:
The total amount owed in 6 months is $569.80
Answer:
We have the equation:
(ax^2 + 3x + 2b) - (5x^2+bx-3c)= 3x^2 - 9
First, move all to the left side.
(ax^2 + 3x + 2b) - (5x^2+bx-3c) - 3x^2 + 9 = 0
Now let's group togheter terms with the same power of x.
(a - 5 - 3)*x^2 + (3 - b)*x + (2b + 3c + 9) = 0.
This must be zero for all the values of x, then the things inside each parenthesis must be zero.
1)
a - 5 - 3 = 0
a = 3 + 5 = 8.
2)
3 - b = 0
b = 3.
3)
2b + 3c + 9 = 0
2*3 + 3c + 9 = 0
3c = -6 - 9 = -15
c = -15/3 = -5
Then we have:
a = 8, b = 3, c = -5
a + b + c = 8 + 3 - 5 = 6
