What is 180(n-2)=s when solving for N​
Sergio039 [100]

Answer:

n = s/180 +2

Step-by-step explanation:

180(n-2)=s

Distribute

180n - 360 =s

Add 360 to each side

180n -360+360 = s+360

180n = s+360

Divide each side by 180

180n/180 = s/180 + 360/180

n = s/180 +2

A sound receiving dish used at outdoor sporting events is constructed in the shape of a paraboloid, with its focus 8 inches from
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
