Solve by completing the square p^2 +10p - 3 = 0

Mrac [35]

Solving $p^2 +10p - 3 = 0$ by completing the square method we get $(p+5)^2-28=0$

Step-by-step explanation:

We need to solve by completing the square method.

We are given: $p^2 +10p - 3 = 0$

The Completing square method is: (a+b)^2 = a^2+2ab+b^2

Solving:

$p^2 +10p - 3 = 0\\For \,\,making\,\,perfect\,\,square\,\,we\,\,add\,\,and\,\,subtract\,\,(5)^2\\p^2+2(p)(5)^2+(5)^2-3-(5)^2=0\\(p+5)^2-3-25=0\\(p+5)^2-28=0$

Solving $p^2 +10p - 3 = 0$ by completing the square method we get $(p+5)^2-28=0$

Assuming cos t = .45 and cos w = .89, both t and w are positive, and both t and w determine a terminal point in quadrant 4, then

FromTheMoon [43]

Assuming both angles indicate a point on the unit circle in quadrant 1, which is described in polar coordinates as having a range of 0 to pi/2 or 0 to 90 degrees, the cosine of a value decreases as angle increases. Naturally, since cos t = 0.45 and cos w = 0.89, cos t < cos w, therefore t > w.

Slope m= (y2-y1)/(x2-x1)=(8-0)/(2-(-2))=8/4=2

y=mx+b
y=2x+b
Take the point (-2,0)
0=2*(-2)+b
b=4
y=2x+4=2(x+2)

Answer is A. y=2(x+2)
