Answer:

4^0

Step-by-step explanation:

The rules of exponents are ...

(a^b)(a^c) = a^(b+c)

(a^b)/(a^c) = a^(b-c)

So, your expression simplifies to ...

$4^5\times4^{-7}\div4^{-2}=4^{5-7-(-2)}=\boxed{4^0}$

What is the equation of the parabola, in vertex form, with focus at (1,-4) and<br> directrix x= 3?

lilavasa [31]

Answer:

D.

Step-by-step explanation:

1) according to the definition of parabola d(focus)=f(directrix),

2) then

$d(focus)=\sqrt{(x-1)^2+(y+4)^2} \ and \ d(directrix)=|x-3|;$

$\sqrt{(x-1)^2+(y+4)^2} =|x-3|;$

3) after evoluation the equation:

(y+4)²=-4x+8 or (y+4)²= -4(x-2);

4) correct answer is D.
