Option C:

It is  \frac{1}{3} throughout the line.

Solution:

Point on the larger shaded triangle are (0, 0) and (–6, –2).  

Point on the smaller shaded triangle are (–6, –2) and (–9, –3).

Slope of the line:

 $m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

Slope of the larger triangle:

Here,  x_{1}=0, y_{1}=0, x_{2}=-6, y_{2}=-2

 $m=\frac{-2-0}{-6-0}

 $m=\frac{-2}{-6}

 $m=\frac{1}{3}  

Slope of the smaller triangle:

Here,  x_{1}=-6, y_{1}=-2, x_{2}=-9, y_{2}=-3

 $m=\frac{-3-(-2)}{-9-(-6)}

 $m=\frac{-3+2}{-9+6}

 $m=\frac{-1}{-3}

 $m=\frac{1}{3}

Both slopes are equal.

It is  \frac{1}{3} throughout the line.

Hence option B is the correct answer.

Write 2/3 as a decimal rounded to 3 sighificant figures
jasenka [17]

Answer:

0.667

Step-by-step explanation:

2/3= 0.66666

Dividing the given value to obtain the decimal value gives:

\frac{2}{3} =0.6666666666666667

The last number is 7 which is greater than 5 this will increment the previous number by 1.

As,the previous values are also '6', so this step will continue till three significant figures.

   0.666666666666667\\0.66666666666667\\0.6666666666667\\0.666666666667\\0.66666666667\\0.6666666667\\0.666666667\\0.66666667\\0.6666667\\0.666667\\0.66667\\0.6667\\0.667

             

So the value rounded up to 3 significant is 0.667

Find the general solution for cos x = 0, where n is an integer.
Romashka-Z-Leto [24]
First we solve this equation:
x = cos^-1(0) = pi/2 and 3pi/2

Now, this is the answer for angles between 0 and 2pi

but there are "negative angles" and angles larger than 2pi
so the general solution that includes all of these cases is:

x = pi/2 + n*pi

here n is any integer.
