Answer: x = 0</h3>
Work Shown:
y = -3x^2 - 12 is the same as y = -3x^2 + 0x + (-12)
Compare this to y = ax^2 + bx + c, and we'll find that
a = -3
b = 0
c = -12
Plug the 'a' and 'b' values into the formula below and simplify
h = -b/(2a)
h = -0/(2*(-3))
h = 0
The x coordinate of the vertex is x = 0, so the axis of symmetry is also x = 0.
The axis of symmetry lays perfectly on top of the y axis.
Answer:
The final balance is $1,193.46.
The total compound interest is $393.46.
Step-by-step explanation:
The final balance is $1,820.62.
The total compound interest is $520.62.
The compound interest on initial balance is $393.46.
The compound interest on additional deposits is $127.16.
The final balance of initial money is $1,193.46.
The final balance of additional deposit is $627.16.
The sum of the additional deposits is $500.
The total principal (initial balance plus total additional deposits) is $1,300.

Answer:
28
Step-by-step explanation:
Number of coins in the bag ⇒ 84
Give that,
Dimes : Nickels : Pennies
3 : 2 : 1
You can see that, there are 6 parts . ( 3 + 2 + 1 = 6 )
And now let us write the types of coins in fractions.
Dimes ⇒ 
Nickels ⇒ 
Pennies ⇒ 
And now they're asking for the number of nickels.
To find that, you can multiply 84 ( number of coins) by it's fraction ( 2/6).
Let us solve.
84 ×
28
Therfore, there are 28 nickels.
