A local hockey rink is covered by a dome in the shape of a hemisphere. If the floor of the arena has a diameter of 250 feet what is the surface area of the domed roof? Nasa is building a satellite that is roughly the shape of a sphere. If the satellite weighs 14,25 pounds per cubic foot before the launch and has a diameter of 4.7 feet. What is the total weight in pounds?

both graphs increase on their domain

neither graph has a y-intercept

step-by-step explanation:

the following points can be visualized easily from the graph

rotation point l

step-by-step explanation:

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

step-by-step explanation:

formula

x = x1 + p/w(x2 - x1)

let the line segment ab with a(x1,y1) and b(x2,y2)

a point(x,y) divide ab in the ratio, 2: 3 the x coordinate can be written as

x = x1 + p/w(x2 - x1)

here p=2 and w = 2+3

therefore,

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

similarly y coordinate y = y1 + 2/5(y2 - y1)
