$n = 0$

Step-by-step explanation:

<h2><em>Factor the </em><em>expression</em></h2>

<em> $2n ^ 3 - 3n ^ 2 + 2n = 0$ </em>

<h2><em>Separate into possible cases</em></h2>

<em> $n(2n ^ 2 - 3n + 2) = 0$ </em>

<h2><em>Solve the equation</em></h2>

<em> $n = 0[tex]n = 0 \: \: \: \: \: \: \: \: [tex]n = 0 \: \: \: \: \: \: \: \: 2n ^ 2 - 3n + 2 = 0$ </em>

<h2><em>Find the union</em></h2>

<em> $n = 0[tex]n = 0 \: \: \: \: \: \: [tex]n = 0 \: \: \: \: \: \: n = R$ </em>

<h2><em>there </em><em>for </em></h2>

<em> $n = 0$ </em>

First, subtract to get the difference.
2.85 – 2.78 = 0.07

Next, divide 2.78 by 100
2.78 ÷ 100 = 0.0278
So, 0.0278 is 1%. Divide 0.07 by 0.0278 to get the answer.
0.07 ÷ 0.0278 ≈ 2.518
2.518 ≈2.5
Therefore, the percentage increase is approximately 2.5% (that's the answer).

Hope this helps!

The answer is 120. Because inscribed angle is Half of the arc measure. Double 60 and we get 120.

A. 70°

Supplementary angles always = 180°

Where 180 - 110 = 70

110+ 70 = 180
