If the vertex of a parabola is (-4, 6) and another point on the curve is (-3, 14), what is the coefficient of the squared expres

Luda [366]

$\bf \qquad \textit{parabola vertex form}\\\\\begin{array}{llll}
\boxed{y=a(x-{{ h}})^2+{{ k}}}\\\\
x=a(y-{{ k}})^2+{{ h}}
\end{array}\qquad\qquad vertex\ ({{ h}},{{ k}})\\\\
-------------------------------\\\\
vertex\ (-4,6)\qquad 
\begin{cases}
h=-4\\
k=6
\end{cases}\implies y=a(x-(-4))^2+6
\\\\\\
y=a(x+4)^2+6
\\\\\\
\textit{we also know that }
\begin{cases}
x=-3\\
y=14
\end{cases}\implies 14=a(-3+4)^2+6$

solve for "a"

You deposit $3000 in an account earning 4% interest compounded continuously. How much will you have in

V125BC [204]

Answer: $3,664.21

Formula: $A=Pe^{rt}$

P = principle/original amount = $3000
r = rate of interest = 4% = 0.04
t = time period (in years) = 5
A = the new amount
e = Euler's number ≈ 2.718...

Substitute in the values:

$A=(3000)e^{(0.04)(5)} =(3000)e^{0.2} =(3000)(1.2214)=3664.208$

<u>Approximately $3,664.21</u>

<em>I think this is how you solve it o_O</em>
