I'm taking a homeschooling course and my parents put me in a couple grades before my level, so its a little difficult for me sometimes. So if someone could explain this it would be super helpful. ^_^ Select the correct scientific notation form of this numeral using only 2 significant figures. 8,421,032.9266

8.4 * 10^6

Step-by-step explanation:

Hope this helps^^

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)
