A (0,0) is at the origin.
P is at (10, -5).
Let the coordinates of B be (x,y).
Because A, B, and P are collinear and PB : AB = 2/7, therefore
x = (7/9)*10 = 7.78
y = (7/9)*(-5) = -3.89
The distance between B and the x-axis is 3.89
The distance between B and the y-axis s 7.78
Answer: The x-axis is closer to B
Answer:
-2x^2 +x -10
Step-by-step explanation:
-3x + xᶺ2 – 8 + 4x – 3xᶺ2 – 2
Combine like terms
x^2 - 3x^2 -3x+4x -8-2
-2x^2 +x -10
(x - x₀)² + (y - y₀)² = r²
x₀=-4; y₀=3; r=5;
(x - (-4))² + (y - 3)² = 5²
(x + 4)² + (y - 3)² = 25

The atomic weight of the new element is simply the weighted average of the isotopes. So
0.4030 * 296.78 + 0.5970 * 300.88
= 119.60234 + 179.62536
= 299.2277
Now the number of significant digits is the same as the number of significant digits of the LEAST PRECISE DATUM. And that would be the percentages at 4 significant digits each. So the result needs to be rounded to 4 significant digits which is 299.2</span>
