Three consecutive integers add up to -36. What are the integers?

nasty-shy [4]

Answer:

We know our answer is correct because 11 + 12 + 13 equals 36 as displayed Below

Explanation

3X + 3 = 36 3X + 3 - 3 = 36 - 3 3X = 33 3X/3 = 33/3 X = 11 Which means that the first number is 11, the second number is 11 + 1 and the third number is 11 + 2. Therefore, three consecutive integers that add up to 36 are 11, 12, and 13. 11 + 12 + 13 = 36 We know our answer is correct because 11 + 12 + 13 equals 36 as displayed above. Therefore, three consecutive integers that add up to 36 are 11, 12, and 13. 11 + 12 + 13 = 36

Compute the directional derivative of the following function at the given point P in the direction of the given vector. Be sure

borishaifa [10]

Answer:

The directional derivate is given by: $D_{u}(x,y) = \frac{6}{\ln{17}\sqrt{10}}$

Step-by-step explanation:

The directional derivative at point (x,y) is given by:

$D_{u}(x,y) = f_{x}(x,y)*a + f_{y}(x,y)*b$

In which a is the x component of the unit vector and b is the y component of the unit vector.

Vector:

We are given the following vector: $v = (3,1)$

Its modulus is given by: $\sqrt{3^2 + 1^2} = \sqrt{10}$

The unit vector is given by each component divided by it's modulus. So

$v_u = (\frac{3}{\sqrt{10}}, \frac{1}{\sqrt{10}})$

This means that $a = \frac{3}{\sqrt{10}}, b = \frac{1}{\sqrt{10}}$

Partial derivatives:

$f(x,y) = \ln{(2 + 3x^2 + 3y^2)}$

So

$f_x(x,y) = \frac{6x}{\ln{(2 + 3x^2 + 3y^2)}}$

$f_x(1,-2) = \frac{6(1)}{\ln{(2 + 3(1)^2 + 3(-2)^2)}} = \frac{6}{\ln{17}}$

$f_y(x,y) = \frac{6y}{\ln{(2 + 3x^2 + 3y^2)}}$

$f_y(1,-2) = \frac{6(-2)}{\ln{(2 + 3(1)^2 + 3(-2)^2)}} = -\frac{12}{\ln{17}}$

Directional derivative:

$D_{u}(x,y) = f_{x}(x,y)*a + f_{y}(x,y)*b$

$D_{u}(x,y) = \frac{6}{\ln{17}}\times\frac{3}{\sqrt{10}}-\frac{12}{\ln{17}}\times\frac{1}{\sqrt{10}}$

$D_{u}(x,y) = \frac{18}{\ln{17}\sqrt{10}} - \frac{12}{\ln{17}\sqrt{10}}[tex][tex]D_{u}(x,y) = \frac{6}{\ln{17}\sqrt{10}}$

The directional derivate is given by: $D_{u}(x,y) = \frac{6}{\ln{17}\sqrt{10}}$
