What is the solution of the inequality 9 - x^2<0?

Dmitry_Shevchenko [17]

Answer:

$x < -3\quad \mathrm{or}\quad \:x > 3$

Step-by-step explanation:

Given:

$9-x^2 < \:0$

Solve:

$\mathrm{Subtract\:}9\mathrm{\:from\:both\:sides}$

$9-x^2-9 < 0-9$

$\mathrm{Simplify}$

$-x^2 < -9$

$Multiply\:both\:sides\:by\:-1\:$

$\left(-x^2\right)\left(-1\right) > \left(-9\right)\left(-1\right)$

$\mathrm{Simplify}$

$x^2 > 9$

$\mathrm{For\:}u^n\: > \:a\mathrm{,\:if\:}n\:\mathrm{is\:even}\mathrm{\:then\:}u\: < \:-\sqrt[n]{a}\:or\:u\: > \:\sqrt[n]{a}$

$x < -\sqrt{9}\quad \mathrm{or}\quad \:x > \sqrt{9}$

$\sqrt{9}=3$

$x < -3\quad \mathrm{or}\quad \:x > 3$

China generated 237.188 billion kilowatt-hours (kWh) of wind energy in 2018. The population in China in 2018 was 1.379 billion.

maw [93]

Answer:

172 kilowatts.

Step-by-step explanation:

Energy : 237.188 billion = 237,188,000,000 = 2.37188 × 10¹¹

People : 1.379 billion = 1,379,000,000 = 1.379 × 10⁹

Divide both values : 2.37188 ÷ 1.379 = 1.72; 10¹¹ ÷ 10⁹ = 10² ⇒ 1.72 × 10² or 172 kilowatts.
