The answer is: "1" . ________________________________ Explanation: ________________________ To start, we find this coordinates of this "point that splits the segment in half", known as the "half-point"; or, even more formally, known as the "midpoint", using the following "midpoint formula"; in which "M" refers to the "midpoint": ____________________________________ Given two coordinates (points) on a (straight line segment): ______________________________ (x₁, y₁) ; AND: (x₂ ,y₂ ) ;
The midpoint , "M": ___________________________________ M = (x₁ + x₂) / 2 , (y₁ + y₂) / 2 ; ____________________________________
in which: " (x₁ + x₂) / 2 " ; refers to the "x-coordinate" of the midpoint;
AND: "(y₁ + y ₂) / 2 " ; refers to the "y-coordinate" of the midpoint; _______________________________________________________ If given two particular points, use can use point to start with, as long os the second one is used for the next one: ___________________________________________________ So, given: Point A: (4,3) ; 4 = x₁ ; 3 = y₁ ; Pont B: (-2,6) -2 = x₂ ; 6 = y₂ ; ___________________________________________________ The midpoint , "M": ___________________________________ M = (x₁ + x₂) / 2 , (y₁ + y₂) / 2 = ? Substitute the values: _______________________________________________ M = [4 +(-2)] / 2 , (3 + 6) / 2 ;
→ [(4 <span>− 2) / 2 ] , [(3+6) / 2 ] ;
</span>→ (2/2), (9/2) ;
→ (1, 4.5) __________________________________ The midpoint is: (1, 4.5). This very question asks to find the "x-value" of the midpoint, which is "1" . (Since: x =1, y = 4.5). ________________________________________ So, the answer is: "1" . __________________________________________________
Differences between the Troposphere and the Stratosphere:
The troposphere is the lowest level of the atmosphere, so it is in contact with the Earth’s surface. In contrast, the stratosphere is located above the troposphere, so it is not in contact with the Earth’s surface. Humans live in the troposphere, not the stratosphere. People only spend time in the stratosphere is when they are traveling through it on an airplane, or flying through it while riding in a rocket. The air density and air pressure are much lower in the stratosphere. In fact, stratospheric air is too thin for people to be able to survive without pressurized air to breathe.
The first gulf war is between the coalition forces led by the US against Iraq. It is also know as Persian gulf war, Kuwait war, first Iraq war, or Iraq war. It started on August 2, 1990 and ended on February 28, 1991. While the six-day war is the conflict between Israel and Egypt in 1967 and Yom Kippur War in 1973.
