Dan states that \frac{1}{7} 7 1 ​ is not a rational number because when you divide 1 by 7 you get a non-terminating decimal. Why is Dan mistaken?

Write the summation to estimate the area under the curve y = 1 + x2 from x = -1 to x = 2 using 3 rectangles and right endpoints

The point a is at –2 and the point b is at 7. marissa would like to divide this line segment in a 4: 3 ratio, and she would like to use the formula x = (x2 – x1) + x1. what values should she substitute into the formula? a = a + b = x1 = x2 =
