GEOMETRY HELP PLEASE

Darya [45]

A line adds up to equal 180 degrees. And adjacent angles also add to equal 180 since they share a side on a line. So add them together and make them equal 180
9x - 7 + 8.5x + 4 = 180
17.5x - 3 = 180
17.5x = 183
x = 10.5

The roots of \[z^7 = -\frac{1}{\sqrt{2}} - \frac{i}{\sqrt{2}}\]are $\text{cis } \theta_1$, $\text{cis } \theta_2$, $\dots$, $\te

stepan [7]

Decoding the LaTeX that didn't render, we seek sum of the angles of the seventh roots of

$- \frac 1 {\sqrt 2} - \frac i {\sqrt{2}}$

That's on the unit circle, 45 degrees into the third quadrant, aka 225 degrees.

The seventh roots will all be separated by 360/7, around 51 degrees. The first seventh root has

$\theta_1 = 225^\circ / 7$

That's around 32 degrees.

The next angle is

$\theta_2 = \frac{1}{7}( 225^\circ + 360^\circ)$

The next one is

$\theta_3 = \frac{1}{7}( 225^\circ + 720^\circ)$

and in general

$\theta_n = \frac{1}{7}( 225^\circ + (n-1)360^\circ) = \frac 1 7(-135^\circ + 360^\circ n)$

$S = \displaystyle \sum_{n=1}^7 \theta_n = \frac{1}{7} \sum_{n=1}^7 -135^\circ + \frac{360}{7} \sum_{n=1}^7 n$

The first sum is just -135° since it's one seventh of the sum of seven -135s.

We have 1+2+3+4+5+6+7 = (1+7)+(2+6)+(3+5) + 4 = 28 so

$S = -135^\circ + 360^\circ (\frac{28} 7) = 4(360)-135 = 1305^\circ$

If I didn't screw it up, that means the answer is

Answer: 1305°

Mr. Yueng graded his students’ math quizzes.

Artyom0805 [142]

For this case we must solve the following equation:

$x ^ 3 = 22$

If we apply cubic root to both sides of the equation, then we eliminate the exponent on the left side:

$\sqrt [3] {x ^ 3} = \sqrt [3] {22}\\x = \sqrt [3] {22}$

That is the exact solution of the equation. Its decimal solution is given by:

$x = \sqrt [3] {22} = 2.8020$

ANswer:

The solution to the equation is $x = \sqrt [3] {22} = 2.8020$

Which of the following fractions would use bar notation? 5/6 1/10 1/20 1/12

OLga [1]

Answer:

I am pretty sure 5/6 and 1/12

Step-by-step explanation:

Because 5/6 = 0.83333 (repeating) -- which means you use bar notation over the three

The same for 1/12 = 0.083333 (repeating) -- which means you use bar notation over the three
