Question 10 (2 points)

Mathematics
1 answer:
igomit [66]2 years ago

Answer:

a = 2

Step-by-step explanation:

To find the missing length we can use the Pythagorean theorem. Also, because it's a right triangle it makes it the perfect candidate!

The Pythagorean Theorem states:

a^2 + b^2 = c^2

Next, we substitute the letters with our given numbers (keep in mind that c is the hypotenuse which is the side facing the right angle)

a^2 + 2.1^2 = 2.9^2

Finally, we solve our equation (hint: use the calculator if needed)

a^2 = 4 (your answer is not final yet. You have to take the square root of both numbers)

a = 2 (Now that's the final answer!)

Genrish500 [490]

\bf (\stackrel{x_1}{5}~,~\stackrel{y_1}{2})\qquad (\stackrel{x_2}{0}~,~\stackrel{y_2}{7}) ~\hfill \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{7}-\stackrel{y1}{2}}}{\underset{run} {\underset{x_2}{0}-\underset{x_1}{5}}}\implies \cfrac{5}{-5}\implies -1 \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{2}=\stackrel{m}{-1}(x-\stackrel{x_1}{5}) \\\\\\ y-2=-x+5\implies y = -x+7

HURRY!!!<br><br> How is completing the square beneficial?<br><br> (in quadratic equation)
givi [52]
"Completing the square" is a step in the solution of quadratic equations. It can be accomplished without the guesswork or trial-and-error associated with methods like factoring, and it always leads to a solution. It is the method by which the quadratic formula is derived.
