Answer:
Graphic is showed in the figure below
Step-by-step explanation:
To graph the equations given, let's do a table for positive values of x, and, by replacing it in the equation, let's calculate the value of y. Knowing the coordinate points (x,y) we can build the graphic.
<em>x y= x + 1/x² y = 1/x</em>
1 2 1
2 2.25 0.2
3 3.11 0.33
4 4.06 0.25
When x->0 both equations -> ∞, because lim(1/x) x->0 = ∞
The graphic is showed below. In red there is y = 1 + 1/x² and in blue y = 1/x
Answer:
5.51 meters
Step-by-step explanation:
The given equation is a wave function. When plotted, the graph is shown in the attached picture. However, the unit is in degrees instead of radians. A unit of π is equivalent to 180°. This plot could determine one variable if the other is given.
Answer:
8x2-30x+27 has one root (9/4) the square of the other (3/2)
Step-by-step explanation:
8x2+30x+27 = (2*x+3)*(4*x+9) => solution = {-3/2, -4/9}
One is not the square of the other because squares are positive.
8x2-30x+27 = (2*x-3)*(4*x-9) =>
solution = {3/2, 4/9} since (4/9 = (3/2)^2, therefore the preceding question is correct.
