progressions

Progressive waves Stationary waves The disturbance produced in the medium travels onward, it being handed over from one particle to the next. Each particle executes the same type of vibration as the preceding one, though not at the same time. There is no onward motion of the ..

Let a=first term, d = common difference, l=t n =last term, s = required sum. Then, Writing the series in the reverse order, Adding together the two series, ..

Water is being poured into a rectangular tank at a steady rate. Which graph relates the height of the water to the progress of time? => Graph 2 or Graph 1 or Graph 3 or None of the above..

David test scores for his first four tests of the school year are shown as both a bar graph and a line graph. Which of these graphs best explains you his progress and why? => neither, only a line plot would best represent the data or line graph, because a line graph shows changes over tim..

The measures of the interior angles of a convex polygon are in arithmetic progression. If the smallest angle is 105° and the largest angle is 135° then find the number of sides of the polygon. => 6 or 5 or 8 or 7..

If α > 0, β > 0, γ > 0 and α + β + γ = π 2 and cot α , cot β , cot γ are in arithmetic progression, then find the value of cot α cot γ. => 2cot² β or 2cot β or 1 or 3..

The sum of n terms of an Arithmetic Progression, S n , is given by the formula S n = n 2 ( a + l ), where a is the first term and l is the last term of the A.P. Find the first term of the A.P. if its last term is 10, and the sum of 5 terms is 40. => 0 or 5 or 7 or 6..
