Answer:

3rd quadrant

Step-by-step explanation:

  • First we just convert the angle from radians to degrees
  • \frac{31\pi radians }{6}*\frac{180degrees}{\pi radians}  =\frac{31*180}{6} degrees=930degrees
  • Now that's too big, all this means is if we start rotating from the positive y-axis in a circle we will cross the starting point 2 times, 2 full circles;
  • 930degrees-360degrees=570degrees\\570degrees-360degrees=210degrees  
  • Now in which quadrant it 210 degrees?
  • 0 degrees to 90 degrees is 1st quadrant
  • 90 degrees to 180 degrees is 2nd quadrant
  • 180 degrees to 270 degrees is 3rd quadrant
  • 270 degrees to 360 degrees is 4th quadrant
  • So our answer is the 3rd quadrant.

Elza [17]

Answer:

2a^4+5a^3-6a^2+19a-20

Step-by-step explanation:

(a^2+3a-4)(2a^2-a+5)

2a^4-a^3+5a^2+6a^3-3a^2+15a-8a^2+4a-20

2a^4-a^3+6a^3+5a^2-3a^2-8a^2+15a+4a-20

2a^4+5a^3+2a^2-8a^2+19a-20

2a^4+5a^3-6a^2+19a-20

liberstina [14]

Answer:

1.

<u>An extraneous solution is a root of a transformed equation that is not a root of the original equation as it was excluded from the domain of the original equation.</u>

It emerges from the process of solving the problem as a equation.

2.I begin like:

The vertical asymptotes will occur at those values of x for which the denominator is equal to zero:

for example:

x² − 4=0

x²= 4

doing square root on both side

x = ±2

Thus, the graph will have vertical asymptotes at x = 2 and x = −2.

To find the horizontal asymptote, the degree of the numerator is one and the degree of the denominator is two.

A rectangle has a width of 10cm. The rectangle length is 4 times its width
Nana76 [90]

Answer:

P = 100 centimeters (assuming you are asking for the perimeter)

Step-by-step explanation:

P = 2 (L + W) OR P =  2L + 2W where P equals the perimeter, L equals the length, and W equals the width.

Since the rectangle's length is 4 times its width and given we know the width is 10 centimeters, then the length is 40 centimeters. Now we can substitute these values in our formula, okay?  

P = 2 (L + W)  

P = 2 (40 + 10)  

P = 80 + 20  

P = 100 centimeters
