How high is the tree in cm

Ipatiy [6.2K]

A^2 + b^2 = c^2.....a and b are the legs and c is the hypotenuse
4^2 + b^2 = 5^2
16 + b^2 = 25
b^2 = 25 - 16
b^2 = 9
b = sq rt 9
b = 3 m

1 meter = 100 cm....so 3 meters = 3(100) = 300 cm
ur answer : the tree is 300 cm high

What number is represented by −3x²+√2x+1/2 when x=√2?

Mila [183]

Answer:

at x = $\sqrt{2}$ , $-3x^{2} + \sqrt{2}x + \frac{1}{2}$ = -3.5

Step-by-step explanation:

The given equation is $-3x^{2} + \sqrt{2}x + \frac{1}{2}$

Now, substitute the value of x = $\sqrt{2}$ in the above equation.

The given equation simplifies to,

$-3(\sqrt{2})^{2} + (\sqrt{2})(\sqrt{2}) + \frac{1}{2}$

now, $\sqrt{2} . \sqrt{2} = 2, \textrm{and} (\sqrt{2} )^{2} = 2$

So, the equation become

-3(2) + 2 + (1/2) = $-6 + 2 + \frac{1}{2} = -4 + \frac{1}{2} = \frac{-8 + 1}{2} = \frac{-7}{2}$

= -3.5

So, at x = $\sqrt{2}$ , $-3x^{2} + \sqrt{2}x + \frac{1}{2}$ = -3.5
