Depends on what you’re asking here. if the equation is abc then it’s 72. it’s it’s abc(3) then it’s 216.

abc= (-6)(-4)(3)=72
but
abc(3)= (-6)(-4)(3)(3)= 216

Find the maximum rate of change of f at the given point and the direction in which it occurs. f(x, y) = 9 sin(xy), (0, 8)

malfutka [58]

Answer:

The magnitude is $\Delta f(0,8) = 72$

The direction is $i$ i.e toward the x-axis

Step-by-step explanation:

From the question we are told that

The function is $f(x, y) = 9sin(xy) \ \ \$

The point considered is $(0,8 )$

Generally the maximum rate of change of f at the given point and the direction is mathematically represented as

$\Delta f(x,y) = [\frac{\delta f(x,y)}{\delta x } i + \frac{\delta f(x,y)}{\delta y } j ]$

$\Delta f(x,y) = [\frac{\delta (9sin(xy))}{\delta x} i + \frac{\delta (9sin(xy))}{\delta y} i ]$

$\Delta f(x,y) = [9y cos (x,y) i + 9xcos (x,y) j]$

At $(0,8 )$

$\Delta f (0,8) = [9(8) cos(0* 8)i + 9(8) sin(0* 8)j ]$

$\Delta f (0,8) = 72 i$

On 12/31/18, Hite Industries reported retained earnings of $475,000 on its balance sheet, and it reported that it had $135,000 o

olganol [36]

Answer:

Dividends = $105000

So option (c) will be correct answer

Step-by-step explanation:

We have given that Retained earning on 12/31/18 is $475000

And retained earning on 12/31/18 is $445000

Net income = $135000

Change in retained income = $475000-$445000 = $30000

We have to find dividends

We know that dividends is given by

Dividends = net income - change in retained income = $135000-$30000 = $105000

So option (c) will be correct answer

Each person attending a two-day conference receives 4 meal vouchers to use.

Lisa [10]

Part A: Let x and y be the number of persons attending the two-day conference and y be the number of vouchers released. The equation that would best express the given is,
y = 4x

Part B: The number of people attending the conference is determined by dividing the given number of vouchers by 4. The answer is 956.

How do I solve 12(9-6x)=696-12?

nignag [31]

Answer:

x= -8

Step-by-step explanation:

This can be done several ways:

The easiest is to factor out 12 from both sides so:

12(9-6x) = 12 (58-1)

12(9-6x) = 12 (57)

Cancel 12 from both sides so:

9-6x = 57, then...

-6x = 48

x= -8
