You can find the number with the next lower unit value and the number with the next higher unit value, then determine which is closer. If they are the same distance, we usually consider the higher one to be "closer." Your number is bracketed by 529 and 530. The distance from 529 is 0.48. The … Read more

The trapezoidal rule approximates the integral of the function f(x) on the interval [a, b] as   (trapezoidal rule)  (b-a)(f(a)+f(b))/2 Simpson's rule uses a second order interpolation to approximate that integral as   (Simpson's rule)  (b-a)(f(a) + 4f((a+b)/2) + f(b))/6 In regions where the first derivative is not substantially constant, Simpson's rule will give better … Read more

9/50 is about 10/50, or 2/10 7/15 is about 7.5/15 = 1/2 or 5/10 An estimate of the sum is (2+5)/10 = 7/10 = 0.7 The actual sum is (9*3+7*10)/150 = 97/150 97/150 ≈ 0.647, so our estimate was a little high. This is because the numbers we used in our estimate were both higher … Read more

You can finish taking the logarithms and see what falls out. You know that   log(ax^b) = log(a) + b*log(x) Using this, you can simplify your expression as follows   5log(2x) - log(x) - log(4x^2)   = 5(log(2) + log(x)) - log(x) - (log(4) + 2log(x))   = 5log(2) - log(4) + 5log(x) - log(x) … Read more

A right triangle with hypotenuse 28 cm and one side 13 cm will have the other side of length √(282 - 132) = √615 ≈ 24.8 cm. Because the base of the ladder is 9 cm from the ground, the top of the ladder will be 33.8 cm from the ground.

Sometimes the numbers work out so you can do the problem without converting to/from improper fractions. 1/6 of the project is complete, so 1 - 1/6 = 5/6 of the project remains to be completed. (5/6)*(6 3/5) = (5/6)*(6) + (5/6)*(3/5) = 5 + 3/6 = 5 1/2 5 1/2 miles of freeway must be … Read more
