Answer:

By Pythagoras theorem, we get

{x}^{2}  +  {x}^{2}  =  {( \sqrt{72}) }^{2} \\ 2 {x}^{2}  =  72 \\  {x}^{2}  = 36 \\  \boxed{x = 6}

<h2>C) <u>6 inches</u> is the right answer.</h2>

Answer:

C)  6 inches

Step-by-step explanation:

(√72)² = x² + x²

72 = 2x²

72/2 = x²

36 = x²

√36 = √x²

6 = x

x = 6 inches

MakcuM [25]

Answer:

A=8.4063u^{2}

Step-by-step explanation:

Be the functions:

y=\frac{3}{x};y=\frac{3}{x^{2}}:x=7

according the graph:

\int\limits^1_7 {\frac{3}{x} } \, dx -\int\limits^1_7 {\frac{3}{x^{2} } } \, dx =3\int\limits^1_7 {\frac{1}{x} } \, dx -3\int\limits^1_7 {\frac{1}{x^{2} } } \, dx=3(\int\limits^1_7 {\frac{1}{x} } \, dx -\int\limits^1_7 {\frac{1}{x^{2} } } \, dx)=3[lnx-\frac{1}{x}](1-7)=3[(ln7-ln1)-(\frac{1}{7}-1)]=3[(1.945-0)-(0.1428-1)]=3*(1.945+0.8571)=3*2.8021=8.4063u^{2}

ruslelena [56]

Answer:

0.07

Step-by-step explanation:

it is given odds in favor of a win is 7 to 93

we have to find the degree of likelihood as a probability

total sample space =7+93=100

so the degree of likelihood as a probability = \frac{7}{100} =0.07

so we can conclude that the probability will be 0.07 which is very less so the chances of win in the casino is very less
