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

The surface area of this cube is 54 square millimeters. What is the volume?

seropon [69]

Answer:

27 cubic millimeters

Step-by-step explanation:

Remember that a cube's surface area is $SA=6s^2$ where $s$ is any side length of the cube.

Hence, by solving $54=6s^2$ , we find that the side length of a cube is 3 millimeters.

This means that the volume of the cube is $V=s^3=3^3=27mm^3$

Question 1:
All sides of an equilateral triangle are equal.
7x - 5 = 3x + 15
Add both sides by 5 and subtract both sides by 3x
4x = 20
x = 5
(Whoa! Watch out for the first choice! We're looking for the length of a side, not the value of x)
Plug x = 5 into 3x + 15.
You get 30. All the sides have a length of 30 in.
The last choice is your answer.

Question 2:
Draw it (or just look at the image).
I'm a terrible artist.
Angle CAB = Angle ACB
Angle CAB + Angle ACB + Angle ABC = 180
2 * Angle CAB + Angle ABC = 180
2x - 6 + 4x - 3 = 180
6x = 189
x = 31.5
(Again! Watch out! We're not looking for the value of x!)
Angle CAB = Angle ACB = x -3 = 31.5 - 3 = 28.5
The first choice is your answer.

Question 3:
The second choice is your answer.
There's not much explanation... That's what it's called.

Have an awesome day! :)
