8/18 = 4/9 ( divide both numerator and denominator by 2 )
√4 = 2 and √9 = 3
$\sqrt{ \frac{8}{18} } = \sqrt{ \frac{4}{9} } = \frac{2}{3}$
Answer: B ) 2/3

It'd be b because if you divide 8/18 by 2 then you get 4/9 then if you square root both of them then you get 2/3

I need help plz pt.2

Fynjy0 [20]

Answer:

See explanation

Step-by-step explanation:

Consider the sequence $\dfrac{1}{32},\ \dfrac{1}{8},\ \dfrac{1}{2}, 2,\ 8,...$

Rewrite it as

$b_1=\dfrac{1}{32},\\ \\b_2=\dfrac{1}{8},\\ \\b_3=\dfrac{1}{2},\\ \\b_4=2,\\ \\b_5=8...$

The points on the coordinate plane are

$(1,b_1),\ (2,b_2),\ (3,b_3),\ (4,b_4),\ (5,b_5),...$ (see attached graph).

Since

$4=\dfrac{b_2}{b_1}=\dfrac{b_3}{b_2}=\dfrac{b_4}{b_3}=\dfrac{b_5}{b_4}...,$ given sequence is geometric.

More on Areas. Farmer Jones, and his wife, Dr. Jones, both mathematicians, decide to build a fence in their field to keep the sh

Olin [163]

Answer:

Area covered by the fences will be 16.1 unit²

Step-by-step explanation:

Let the first parabola is represented by the function f(x) = 6x²

and second parabola by g(x) = x² + 9

point of intersection of the graphs will be determined when f(x) = g(x)

6x² = x² + 9

5x² = 9

x² = 1.8

x = ± 1.34

Now we will find the area between these curves drawn on the graph.

Area = $\int_{-1.34}^{1.34}[f(x)-g(x)]dx=\int_{-1.34}^{1.34}[6x^{2}-(x^{2}+9)]dx$

= $\int_{-1.34}^{1.34}(5x^{2}-9)dx$

= $[\frac{5}{3}x^{3}-9x]_{-1.34}^{1.34}$

= $[\frac{5}{3}(-1.34)^{3}-9(-1.34)-\frac{5}{3}(1.34)^{3}+9(1.34)]$

= $[-4.01+12.06-4.01+12.06]$

= 16.1 unit²
