Answer:

y" = -24 / y³

Step-by-step explanation:

6x² + y² = 4

Take the derivative of both sides with respect to x.

12x + 2y y' = 0

Again, take the derivative of both sides with respect to x.

12 + 2y y" + y' (2y') = 0

12 + 2y y" + 2(y')² = 0

Solve for y' in the first equation.

2y y' = -12x

y' = -6x/y

Substitute and solve for y":

12 + 2y y" + 2(-6x/y)² = 0

12 + 2y y" + 2(36x²/y²) = 0

12 + 2y y" + 72x²/y² = 0

6y² + y³ y" + 36x² = 0

y³ y" = -36x² − 6y²

y" = (-36x² − 6y²) / y³

Solve for y² in the original equation and substitute:

y² = 4 − 6x²

y" = (-36x² − 6(4 − 6x²)) / y³

y" = (-36x² − 24 + 36x²) / y³

y" = -24 / y³

Consider the statement p:x+9=10.which of the following is a equivalent statement

Answers

Answer:

The equivalent expression for x+9=10 is x=1.

Step-by-step explanation:

We have a statement i.e. x+9=10

We need to find an equivalent statement for the above statement.

If we subtract 9 on both sides of the above statement,

x+9-9=10-9

We know that, 9-9=0 and 10-9 =1

x+0=1

x=1

So, the equivalent expression for x+9=10 is x=1.

Sum of the interior angles of any triangle equal 180° .

Thus ;

The angle which facing to the side 4 is 45°.

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

Hint:

In a right triangle, the side facing the 45° angle is √2 / 2 times the hypothenuse .

Thus ;

$( √(2) )/(2) x = 4 \n$

Multiply sides by 2

$2 * ( √(2) )/(2) x = 2 * 4 \n$

$√(2) x = 8 \n$

Divide sides by √2

$( √(2)x )/( √(2) ) = (8)/( √(2) ) \n$

$x = (4 * 2)/( √(2) ) \n$

$x = (4 * √(2) * √(2) )/( √(2) ) \n$

$x = 4 √(2) \n$

$x = hypothenuse = 4 √(2)$

Done...
