Please answer quickly! A radio telescope has a parabolic surface, as shown below. A parabola opening up with vertex at the origi

n is graphed on the coordinate plane. The height of the parabola from top to bottom is 1 meter and its width from left to right is 20 meters. If the telescope is 1 m deep and 20 m wide, how far is the focus from the vertex?

Answer:

Basing on the description, a parabola checking with vertex at origin, the formula with vertex at origin can be used, x^2 = 4py. p is the focus therefore with the dimensions given, we get yourself a 0.25 and this is the distance of the focus to the vertex.

Use multiplying by 1 to find an expression equivalent to 3/14 with a denominator of 14 y.
Soloha48 [4]
As a matter of simplification, same/same = 1.

now, "same" could be anything whatsoever, you name it, a whole polynomial, a whole anything whatsoever.

\bf \cfrac{\sqrt{2}}{\sqrt{2}}=\cfrac{\sqrt{3}}{\sqrt{3}}=\cfrac{100000000}{100000000}=\cfrac{eggs}{eggs}=\cfrac{miles}{miles}=\cfrac{\frac{\quad \sqrt{3}}{\sqrt[5]{17}}\quad }{\frac{\sqrt{3}}{\sqrt[5]{17}}}=\cfrac{whatever}{whatever}=1

now, that said, let us use 1 in this case then ... hmmmm we simply need a "y" in the denominator, so we simply multiply the denominator AND numerator by "y", y/y  = 1 btw.

\bf \cfrac{3}{14}\cdot \cfrac{y}{y}\implies \cfrac{3y}{14y}

Find an equation of the vertical line through (3 comma negative 1 )in the form axplusbyequals​c, where​ a, b, and c are integers
Sati [7]

The equation of the vertical line is 1x+0y=3

Explanation:

It is given that the vertical line passes through the points (3,-1)

For vertical line, the slope is undefined.

Hence, b=0

Let us substitute the coordinate (3,-1) in the equation ax+by=c, we have,

3a+0y=c

Simplifying, we have,

3a=c

3=\frac{c}{a}

where a=1 and c=3

Substituting the values of a, b and c in the equation ax+by=c, we have,

1x+0y=3

Thus, the equation of the vertical line is 1x+0y=3
