Answer:

300

Step-by-step explanation:

the nth term of a sequence is 3n^2 (where n only is squared), then the 10th term of the sequence is; 3 x (10)^2= 3 x 100 = 300.

Enter the inequality of the graph below.

aev [14]

The slope is (8-2)/(0-2)=-3
the y intercept is 8
the equation is y=-3x+8
the area to the left is shaded, and the line is solid, so y $\leq$ -3x+8

Solve each equation by taking square roots<br><br> 2n^2 -8=-33

densk [106]

$2n^2 -8=-33$

$
2n^2=-33+8
 
$ $Add \ 8 \ to \ both \ sides$

$2n^2=-25$

$n^2=- \dfrac{25}{2}$ $Divide \ both \ sides \ by \ 2$

$n=+ \sqrt{ -\dfrac{25}{2} }$ <span> $Take \ the \ square \ root \ of \ both \ sides$
</span>
$n=+ \sqrt{ \dfrac{5i}{ \sqrt{2}}}$
