Answer:
Step-by-step explanation:
X^4 - 10X^2 + 9 =0 This factors. It just looks odd.
(x^2 - 1)(x^2 - 9) = 0
x^2 - 1 = (x + 1)(x - 1) = 0
x = 1 and x = - 1
x^2 - 9 = (x + 3)(x - 3) = 0
x = 3
x = -3
The correct answer is C (third one down).
Answer:
19
Step-by-step explanation:
when you multiply 19 by itself you get 361
<span>I would say she is displaying social facilitation conformity. She would be very likely to dance to her hearts desire when she is alone, however in a group she is anxious and does not want to volunteer. Janie is experiencing what many go through in a crowd or pressuring situation. She is embarrassed.</span>
<span> For a surveyor, the answer is obviously 72 degrees. this is from the fact that total deflection angle for a circular highway curve is 1/2 of the included angle. the explanation is located below.
if you have a tangent at each end of the chord you have an isosceles triangle with two 36 degree angles and one angle of 108 degrees.
Now draw two lines from the points of tangency to the center of the circle. By definition, these radii are perpendicular to the tangent so they make an angle of 90-36 = 54 degrees with the chord.
so now you have an isosceles triangle with two 54 degree angles so the include angle must be 180-54-54 = 72 degrees
Hope this helps :)
