Answer:

It is a right angle .

c=42 m,    a = 7 m ,,,   b = 14 m

FORMULA

Area of triangle =1/2 (b × h)

                        = 1/2 (14 ×7)

                         =49 m²

Do the rays BA and AB define the same ray? In complete sentences, explain why the two rays are the same or why the two rays are
Deffense [45]
Rays are named according to their endpoints, the first one named is the "starting" endpoint, the second one is the one that will continue on into infinity.  Therefore, ray BA has a terminal endpoint at B and goes through point A into infinity.  Ray AB has a terminal endpoint at A and goes through point B into infinity.  Definitely NOT the same ray.

Write the standard form of the line that passes through (-1,-3) and (2,1).
kobusy [5.1K]

Answer:

Step-by-step explanation:

\mathrm{Line\:passing\:through\:}\left(-1,\:-3\right)\mathrm{,\:}\left(2,\:1\right)\\\\\mathrm{Find\:the\:line\:}\\\mathbf{y=mx+b}\mathrm{\:passing\:through\:}\left(-1,\:-3\right)\mathrm{,\:}\left(2,\:1\right)\\\\\mathrm{Compute\:the\:slope\:}\left(-1,\:-3\right),\:\left(2,\:1\right):\quad \\m=\frac{4}{3}\\\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}\\\\\left(x_1,\:y_1\right)=\left(-1,\:-3\right),\:\left(x_2,\:y_2\right)\\\left\\

\\m=\frac{1-\left(-3\right)}{2-\left(-1\right)}\\\\Refine\\\\m=\frac{4}{3}\\\\\mathrm{Compute\:the\:}y\mathrm{\:intercept}:\quad b=-\frac{5}{3}\\\\y=\frac{4}{3}x-\frac{5}{3}\\

Convert equation to standard form

y - \frac{4}{3} x + \frac{5}{3} = 0\\\\Multiply \:through\: by\: 3;\\\\3\times (y - \frac{4}{3} x + \frac{5}{3} )=0\\\\3y -4x+5 = 0\\Arrange\:n\:form\:of \:;\\Ax +By = C\\\\-4x +3y =-5

I am having trouble understanding the concept of completing the square in math. Could someone please assist me on how to do so?
enyata [817]
"Completing the square" is the process used to derive the quadratic  formula for the general quadratic ax^2+bx+c=0.  Suppose you did not know the value of a,b, or c of the quadratic...

ax^2+bx+c=0  You need a leading coefficient of one for the process to work, so you divide the whole equation by a

x^2+bx/a+c/a=0  now you move the constant to the other side of the equation

x^2+bx/a=-c/a  now you halve the linear coefficient, square that, then add that value to both sides, ie, (b/(2a))^2=b^2/(4a^2)...

x^2+bx/a+b^2/(4a^2)=b^2/(4a^2)-c/a  now the left side is a perfect square...

(x+b/(2a))^2=(b^2-4ac)/(4a^2)  now take the square root of both sides

x+b/(2a)=±√(b^2-4ac)/(2a)  now subtract b/(2a) from both sides

x=(-b±√(b^2-4ac))/(2a)

It is actually much simpler keeping track of everything when using known values for a,b, and c, but the above explains the actual process used to create the quadratic formula, which the above solution is. :)
