Refer to the diagram shown.
At an arbitrary point P (x,y) on the parabola, the distance from the focus should be equal to the distance from the directrix.
The distance of P from the focus is
d₁ = √[x² + (y+3)²]
The distance from P to the directrix is
d₂ = 3 - y
Therefore
d₁ = d₂.
That is,
x² + (y+3)² = (3 - y)²
x² + y² + 6y + 9 = 9 - 6y + y²
x² + 12y = 0
y = - (1/12) x²
Answer:
The answer is true not false
<span>A daily periodic interest rate is calculated by dividing the annual percentage rate, or APR, by either 360 or 365, depending on the card issuer.</span>
We have that
<span>a*(3x-8)=b-18x
3ax-8a=18x+b
</span><span>The only way for this to happen (non-trivially) is if the coefficients of x are equal, and the constant terms are equal
</span>so
3ax=18x-----> 3a=18--------> a=6
-8a=b---------> b=-8*6-------> b=-48
the answer is
a=6
b=-48
