10 POINTS!!! FULL ANSWER WITH FULL STEP BY STEP SOLUTION PLEASE

Alla [95]

Let z = √(x^2 +2x +4).
Then your expression becomes
y = (z^2)^z
y = z^(2z)
And the derivative with respect to x is
y' = z^(2z)*(2z' +2ln(z)z')
= (2z')(1 +ln(z))(z^(2z))
Now
z' = (2x +2)/(2√(x^2 +2x +4)
= (x +1)/√(x^2 +2x +4)

So, your derivative is
y' = 2(x +1)/√(x^2 +2x +4) * (1 + (1/2)ln(x^2 +2x +4)) * (x^2 +2x +4)^√(x^2 +2x +4)

For x = 0, this becomes
2(1)/√4 * (1 +(1/2)ln(4)) * 4^√4
= 16*(1 + ln(2))

For what value of x will (x-1)(x+2)/x+2 be undefined

Leya [2.2K]

Using the property that anything over 0 is undefined, we can set x+2 to 0 and solve it to find the undefined points.
$x+2 = 0$
$x = -2$
So when x is -2, the equation will be undefined because of the rules about division by zero.

Coordinates of an endpoint of a line plotted on the coordinate plane are (6, -2). The length of the line is 4 units. Select the

The possible coordinates that could be the other endpoints of a line that has a length of 4 units are: (6, 2), (10, -2), (2, -2), and (6, -6).

<h3>What is the Distance Between Two Points?</h3>

On a coordinate plane, the distance between two points is the number of units in between the two points lying on the same axis.

Let's find the distance between (6, -2) and eaxh of the given endpoints tro know which gives us a length of 4 units.

(6, -2) and (6, 2) = |-2 - 2| = 4 units

(6, -2) and (6, 6) = |-2 - 6| = 8 units

(6, -2) and (10, -2) = |10 - 6| = 4 units

(6, -2) and (2, -2) = |6 - 2| = 4 units

(6, -2) and (6, -6) = |-2 - (-6)| = 4 units

(6, -2) and (-2, -2) = |6 - (-2)| = 8 units

(6, -2) and (-10, -2) = |6 - (-10)| = 16 units

Therefore, the possible coordinates of the other endpoint of the line are: (6, 2), (10, -2), (2, -2), and (6, -6).
