Answer:

w≅8.46ft

Step-by-step explanation:

Data

focus=8

vertex=(0,0)

width=?

depth (y)=3ft

parabola equation: $(x-h)^{2}=4p(y-k)$ ; then for V=(0,0), $x^{2} =4py$ , be focus(f)=8in; $x^{2} =4*8*y=32y$ → $y=\frac{x^{2} }{32}$

we have that y=3ft then $3=\frac{x^{2} }{32}$ ; but 1in≅0.083ft so $x^{2} =3*32*0.083=7.968$ → x=±2.82, finally w=3*2.82≅8.46ft

Illusion [34]

Answer:

The answer is x ≤ 2.

Step-by-step explanation:

Firstly, you have to move the unrelated term to the other side :

$- 9 \leqslant 7 - 8x$

$- 9 - 7 \leqslant - 8x$

$- 16 \leqslant - 8x$

Next you can solve it :

$- 8x \geqslant - 16$

$x \leqslant - 16 \div - 8$

$x \leqslant 2$

*Remember to change the symbol, when it is dividing by a negative value
