Duf(−5,−4) in the direction of the vector 〈−2,−2〉 is 〈((-5)^2)(-4)^3/3, (-5)^3((-4)^2)/3〉 · 〈-1/√2, -1/√2〉 = 500/3.
For the function f(x, y) = (5y^2)ln(3x), we have:
∂f/∂x = (5y^2)/(3x)
∂f/∂y = 10y ln(3x)
Therefore, ∇f = 〈(5y^2)/(3x), 10y ln(3x)〉.
To find Duf(2, 5) in the direction of the vector 〈2, -2〉, we first need to find the unit vector in the direction of 〈2, -2〉:
||〈2, -2〉|| = √(2^2 + (-2)^2) = 2√2
u = 〈2, -2〉 / ||〈2, -2〉|| = 〈1/√2, -1/√2〉
Then, we have:
Duf(2, 5) = ∇f(2, 5) · u = 〈(5(5)^2)/(3(2)), 10(5) ln(3(2))〉 · 〈1/√2, -1/√2〉
= (125/6√2) - (50/√2) ln3.
For the function f(x, y) = ((x^3)(y^3))/9, we have:
∂f/∂x = (x^2)(y^3)/3
∂f/∂y = (x^3)(y^2)/3
Therefore, ∇f = 〈(x^2)(y^3)/3, (x^3)(y^2)/3〉.
To find Duf(-5, -4) in the direction of the vector 〈-2, -2〉, we first need to find the unit vector in the direction of 〈-2, -2〉:
||〈-2, -2〉|| = √((-2)^2 + (-2)^2) = 2√2
u = 〈-2/√8, -2/√8〉 = 〈-1/√2, -1/√2〉
Then, we have:
Duf(-5, -4) = ∇f(-5, -4) · u = 〈((-5)^2)(-4)^3/3, (-5)^3((-4)^2)/3〉 · 〈-1/√2, -1/√2〉
= 500/3.

I need an explanation for the problem 4v2=-12v-9. I don't understand why it factors into 4v+3 and 4v+3
Answer:
The factors are [tex]2v+3,2v+3[/tex].
The factors are not [tex]4v+3,4v+3[/tex]
Step-by-step explanation:
Equation is [tex]4v^2=-12v-9[/tex].
This equation can be written as follows:
[tex]4v^2+12v+9=0[/tex]
Here,
[tex]12v=6v+6v[/tex]
Therefore,
[tex]4v^2+6v+6v+9=0\\2v(2v+3)+3(2v+3)=0\\(2v+3)(2v+3)=0[/tex]
So, the factors are [tex]2v+3,2v+3[/tex].
The factors are not [tex]4v+3,4v+3[/tex]

Actually Welcome to the Concept of the Surface areas and Volumes.
Since, we know that the lateral area of a Right circular cone is given as,
AL = πrl
here, l = slant height , r = radius of the circular base.
so now, we have to find first slant height to get the lateral surface area,
[tex]l \: = \sqrt{ {r}^{2} + {h}^{2} } [/tex]
here, r = 8 cm and h = 15,
hence,
[tex]l \: = \sqrt{64 + 225} = \sqrt{289} = 17cm[/tex]
hence, now we apply the formula,
AL = π(8) (17) cm^2
===> AL = 136 π cm^2

y-2=1/2(x-4) in slope intercept form
Answer:
y = 1/2x
Step-by-step explanation:
y - 2 = 1/2 (x-4)
y = 1/2x - 2 + 2
y = 1/2x
(The y - intercept is 0 because -2 and 2 cancels each other out)
Hope this helps :)
Let me know if there are any mistake!!
The slope intercept form of the equation y - 2 = 1/2 (x - 4) will be
⇒ y = 1/2x
What is equation of line?
The equation of line in slope intercept form is defined as;
y = mx + b
Where, 'm' is slope of line and 'b' is y-intercept.
Given that;
The equation of line is;
y - 2 = 1/2 ( x - 4 )
Now,
We can change the equation of line in slope intercept form as,
y - 2 = 1/2 ( x - 4)
Solve as;
y - 2 = 1/2 x - 1/2 × 4
y - 2 = 1/2 x - 2
Add 2 both side,
y - 2 + 2 = 1/2 x - 2 + 2
y = 1/2 x
Thus, The slope intercept form of the equation y - 2 = 1/2 (x - 4) will be;
⇒ y = 1/2x

Answer:
x = 5 (please read the step by step explanation)
Step-by-step explanation:
So, I'm just going to solve for x because the instructions aren't too clear. I believe there is supposed to be an image attached to it, but seeing as I don't have that, I'll just solve for x and you can plug in with the values.
15x = 12x + 15
Same to both sides:
3x = 15
Isolate x:
x = 5
Just plug in those values and you'll be good to go! Have a good day!
