bixtya [17]

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
