Share. WebThere are also sequences that are much easier to describe recursively than with a direct formula. For example, the Fibonacci sequence, which starts {0, 1, 1, 2, 3, 5, 8...}, with each successive term being the sum of the previous two. While this does have a closed formula, it's very complex and unwieldy. 1 comment ( 12 votes) Aidan C. 4 years ago

WebWhen a whole number is multiplied to 0, the result is always 0, i.e., x.0 = 0.x = 0. Example: 0 × 12 = 0. 12 × 0 = 0. Here, 0 × 12 = 12 × 0 = 0. Thus, for any whole number multiplied by 0, the result is always 0. Division by zero. The division of a whole number by o is not defined, i.e., if x is a whole number then x/0 is not defined. WebFind a quadratic with zeroes at 4 and −5. If the zeroes are at x = 4 and at x = −5, then, subtracting, the factor equations were x − 4 = 0 and x − (−5) = x + 5 = 0. Then the factors were x − 4 and x + 5. Any factorable quadratic is going to have just the two factors, so these must be them. Then the original quadratic was something like: Webgocphim.net harbor freight tools tacoma 6th ave
