Evaluate the limit by first recognizing the sum as the Riemann sum for a function defined on the interval [0,1]: lim as n approa

mina [271]

$\lim_{n \to +\infty} \left ( \dfrac{1}{n} \cdot \left ( \sqrt{ \dfrac{1}{n} } + \sqrt{ \dfrac{2}{n} } + \sqrt{ \dfrac{3}{n} } + \cdots + \sqrt{ \dfrac{n}{n} }} \right ) \right ) =$

$\dfrac{1}{n} \sum_{i = 1}^n \left ( \sqrt{ \dfrac{i}{n} } \right ) = \int\limits^1_0 { \sqrt{x} } \, dx = \left [ \frac{2}{3}x^{ \frac{3}{2} } \right ]^{1}_{0} = \dfrac{2}{3} \cdot 1^{ \frac{3}{2} } - \dfrac{2}{3} \cdot 0^{ \frac{3}{2} } = \boxed{ \dfrac{2}{3} }$

Caleb is putting tile down in his bathroom and needs to know the perimeter of the floor. Two sides rectangular floor are 5 1/3 f

ladessa [460]

Answer:

20 1/6 ft

Step-by-step explanation:

The perimeter is the sum of the lengths of the sides:

2×(5 1/3 ft) + 2×(4 3/4 ft) = 10 2/3 ft + 8 6/4 ft

= 10 2/3 ft + 9 2/4 ft . . . . change 6/4 ft to 1 1/2 ft

= 10 8/12 ft + 9 6/12 ft = 19 14/12 ft . . . . . use common denominator of 1/12 ft

= 20 2/12 ft . . . . . . change 14/12 ft to 1 2/12 ft; next reduce that fraction

= 20 1/6 ft . . . . perimeter of Caleb's bathroom
