 <span>A parabola that has a horizontal directrix is a parabola that opens up or down. 

Here are some of its components: 
1) Standard equation of a parabola with a horizontal directrix: (x-h)^2 = 4a(y-k), 
a = distance from vertex to focus 
2) Vertex at (h,k) 
3) Focus(h,k+a) 
4) Directrix: y = k-a 
5) Axis of symmetry: x = h 

A parabola that has a vertical directrix opens to the right or left and is on its side. 

Here are some components 
1) Standard equation of a parabola with a vertical directrix: (y-k)^2 = 4a(x-h) 
2) vertex (h,k) 
3) focus (h+a,k) 
4) directrix: x = h-a 
5) Axis of symmetry: y = k

Hopes this helps :)</span>

What is the force of gravity (in Newtons) acting between the Earth and a 100-kg person who is on board the International Space S
ratelena [41]

Answer:

f_{G}=317877.55 N = 317.8 kN

Step-by-step explanation:

f_{G}= (G*m_{1}*m_{2})/r^{2}  \\Where:\\f_{G}= force  of  gravity\\G=gravitational constant= 6.6x10^{-11}m^{3}kg^{-1}s^{-2}\\ m_{1}= earth mass = 5.9x10^{24}kg\\m_{2}=person mass = 100kg\\r= distance between the bodies=350km= 350 000 m

Answer this really quick
ivann1987 [24]

Answer:

the equation is y = ax + b (a ≠ 0)

see in the graph, the line passed through (0;3) and (1;5)

=>b = 3

   a + b = 5

<=> a = 2

     b = 3

=> the equation is y = 2x + 3

Parse the regular hexagon, and tell how much regular unit triangle do you find, if the length of one side of the regular hexagon
Thepotemich [5.8K]

Answer:

Six.

Step-by-step explanation:

In geometry, a hexagon is a two-dimensional polygon that has six sides. A regular hexagon is a hexagon in which all of its sides have equal length. We sometimes define a regular hexagon using equilateral triangles, or triangles in which all of the sides have equal length.

The regular hexagon is a convex polygon with six equal sides and six equal angles. Each external angle of the regular hexagon measures 60 degrees. It is closely related to equilateral triangles: Joining each vertex with its opposite, the regular hexagon is divided into six equilateral triangles.
