Answer:

The ladder will reach 5.6 meters high.

Step-by-step explanation:

The tree, the ground and Kali's ladder form a triangle whose hypotenuse h is the ladder, base b the ground, and perpendicular p the tree. Thus from Pythagorean theorem:

p^2+b^2=h^2

Since b=2 and h=6

p=\sqrt{h^2-b^2} =\sqrt{6^2-2^2}=\boxed{5.6\:meters.}

Thus the ladder will reach 5.6 meters high.

X^2 + 1/2x + = 2 + <br> Help please
Gennadij [26K]

Answer:

Step 2:

For Completing the square,

(\frac{1}{2} coefficient\ x)^{2} =(\frac{1}{2}\times \frac{1}{2})^{2}=\frac{1}{16}

Add half coefficient of x square on both the side we get

x^{2}+\dfrac{x}{2}+\frac{1}{16}=2+\frac{1}{16}

Step-by-step explanation:

Solve:

2x^{2}+x-4=0

2x^{2}+x=4

Solution:

Step 1:

Dividing both the side by two we get

x^{2}+\dfrac{x}{2}=2

Step 2:

For Completing the square,

(\frac{1}{2} coefficient\ x)^{2} =(\frac{1}{2}\times \frac{1}{2})^{2}=\frac{1}{16}

Add half coefficient of x square on both the side we get

x^{2}+\dfrac{x}{2}+\frac{1}{16}=2+\frac{1}{16}

Step 3:

We know (a +b)^{2} = a^{2}+2ab +b^{2}

(x+\frac{1}{4})^{2}=\frac{33}{16} \\ \\(x+\dfrac{1}{4})=\pm \sqrt{\dfrac{33}{16}} \\\\x=-\dfrac{1}{4}\pm \sqrt{\dfrac{33}{16}}
