Answer:
(-b/2a, b^2/(4*a) - b^2/2a + c)
Step-by-step explanation:
For a general parabola:
y = a*x^2 + b*x + c
We can write the vertex as:
(h, k)
The x-value of the vertex is the value of the axis of symmetry.
Then we have:
h = x = -b/2a
Now we need to find the y-value of the vertex.
To do that, we just replace the variable "x" by the x-value of the vertex in our equation, so we get:
k = y = a*(-b/2a)^2 + b*(-b/2a) + c
k = b^2/(4*a) - b^2/2a + c
Then the coordinates of the vertex are:
(h, k) = (-b/2a, b^2/(4*a) - b^2/2a + c)
Yes, she will because
E.X.:
<span>Divide the sales tax percentage by 100 (or simply move the decimal point two places to the left) to get the decimal equivalent of the rate. So if the tax rate was 7.375%, the decimal equivalent would be .07375.<span>Multiply the taxable price by the decimal equivalent of the rate. For example, if the taxable price was $50.00 and the rate was 7.375%, then the sales taxes would be $3.69 ($50 x .07375 = 3.6875 = $3.69 when rounded to the nearest cent). Hopes this helps if not I can explain it better.</span></span>
I = p*r*t
$3000=p*.06*5=?
Multiply and you would have yor answer(rounded to nearsest cent)!
