$sin \vartheta = \frac{5}{12}$

$\vartheta = sin^{-1}(\frac{5}{12})$

which is approximately 24.6243°

Therefore, the missing angle is 24.6243° which is about 0.429775 radians (all corr. to 6 sig. fig.)

$\sqrt{x-1}=x$

$x-1=x^2$

$x^2-x+1=0$

$x=\frac{(-1)^2\pm\sqrt{4(1)(1)}}{2(1)}$<------ Quadratic Equation

$= \frac{1}{2}\pm\frac{2}{2}$

x = 3/2 or x=-1/2

There are two solutions.

$\frac{2x^7}{3}-\frac{16x^6}{6}-\frac{509x^5}{22}-\frac{2875x^4}{22}+\frac{15331x^3}{66}+\frac{19447x^2}{33}-\frac{6618x}{11}-\frac{700}{11}$

= $\frac{44x^7}{66}-\frac{176x^6}{66}-\frac{1527x^5}{66}-\frac{8625x^4}{66}+\frac{15331x^3}{66}+\frac{38894x^2}{66}-\frac{39708x}{66}-\frac{4200}{66}$

= $\frac{44x^7-176x^6-1527x^5-8625x^4+15331x^3+38894x^2-39708x-4200}{66}$

$\sqrt{-32}=\sqrt{-1}\sqrt{2}\sqrt{16}=4i\sqrt{2}$

OR

$4\sqrt{2}i$

= 1/42

What kind of dot plot? Linear? Quadratic? 

Also we'll need the function to plot graphs

Btw you can use the plotting calculator.

LOL

1) 4.5 x 2.25 = 10.125

2) 0.5 x 10 x (25+12) = 185

3) 0.5 x 16 x (24+32)28*16 = 448

5.78 x 10^8

It's NOT equal to 1/8 ........It equals to 0.1250000000000659. Notice the 659 at the last
