Answer:
The current price of the item is $600.
The price of the item 9 years from today will be of $756.
Step-by-step explanation:
Price of the item:
The price of the item, in dollars, after t years, is given by:
Current price of the item
This is p(0). So
The current price of the item is $600.
9 years from today.
This is p(9). So
The price of the item 9 years from today will be of $756.
Answer:
the initial height
Step-by-step explanation:
given the height is represented by the function
f(t) = - 16t² + 40t + 3
Then the initial height is when t = 0, that is
f(0) = 0 + 0 + 3 = 3 ← initial height
Let the number be x.
Triple the number means 3x
add 6 means 3x + 6
subtract the number twice 3x + 6 - x - x
the result is the number plus 3 means that the result is x + 3
So, combining these into an equation, we get:
3x + 6 - x - x = x + 3
If we solve this equation for x, we will get:
x + 6 = x + 3
The x will cancel out and we will get : 6 = 3
Therefore, this is a false statement.
Answer:
its kinda blurry
Step-by-step explanation:
-3 = x^2 + 4x + 1
0 = x^2 + 4x + 1 + 3
0 = x^2 + 4x + 4
Discriminant is b^2 - 4ac.
4^2 - 4(1)(4)
16 - 4(4)
16 - 16 = 0
Discriminant Rules:
1. If b²-4ac is negative, there are no real answers.
2. If b²-4ac is zero, there is one real answer.
3. If b²-4ac is positive, there are two real answers.
Based on rule 2, the answer is ONE REAL ROOT.
