Answer:
[tex]\huge\boxed{\sf (k + 8)(k + 8)}[/tex]
Step-by-step explanation:
Given expression:
[tex]k^2+16k+64[/tex]
We can write it as:
[tex]=(k)^2+2(k)(8)+(8)^2[/tex]
Using formula [tex]\bold{a^2+2ab+b^2=(a+b)^2}[/tex]
[tex]=(k+8)^2[/tex]
= (k + 8)(k + 8)

New Berlin Corporation has annual fixed costs of $800,000, variable costs of $48 per unit, and a contribution margin ratio of 40 percent.
a. Compute the unit sales price and unit contribution margin for the above product.
b. Compute the sales volume in units required for New Berlin Corporation to earn an operating income of $600,000.
c. Compute the dollar sales volume required for New Berlin Corporation to earn an operating income of $600,000.
Based on the variable costs and contribution margin, the unit sales price is $80 and the unit contribution margin is $32.
The sales volume in units needed to earn $600,000 is 43,750 units and the amount in dollar sales needed is $3,500,000.
What is the unit sales price and unit contribution margin?The unit sales price can be found as:
= Variable cost / (1 - contribution margin ratio)
= 48 / (1 - 40%)
= $80
Unit contribution margin is:
= Selling price x Contribution margin ratio
= 80 x 40%
= $32
In units, this amount is:
= (Fixed cost + income required) / Contribution margin
= (800,000 + 600,000) / 32
= 43,750 units
In dollar terms the amount needed is:
= Units needed x selling price
= 43,750 x 80
= $3,500,000

13. Write a system of linear equations that has the ordered pair (3, -5) as its solution.
Answer:
[tex]x + y = -2\\x-y=8[/tex]
Step-by-step explanation:
3 is the [tex]x[/tex], and -5 is the [tex]y[/tex].
1) Create two equations that add and subtract them.
[tex]x + y = -2\\x-y=8[/tex]
2) Check whether you get the same answer (3,-5) or not. To do so, you need to solve them simultaneously using the elimination or substitution method. I will demonstrate using the substitution method.
[tex]x = -2 - y\\x-y=8\\(-2 - y) -y =8\\-2-2y=8\\-2y = 8 + 2\\-2y = 10\\y = \frac{10}{-2} \\y = -5[/tex]
To find [tex]x[/tex], substitute the result into one of the two equations. I choose [tex]x+y=-2[/tex].
[tex]x-5=-2\\x = -2 +5\\x = 3[/tex]

Step-by-step explanation:
12,14,16,18 are all greater than 10, which is 4/18 numbers, simplified as 2/9
Answer: 13/18
Step-by-step explanation:
First you add up the amount of even numbers and the amount of numbers greater than 10
2,4,6,8,10 make 5 then add 8 more for 11-18, leaving you with 13 then take 13 and divide it by the total (18) and you will get 0.72 or 13/18

Find constants a and b such that = (axy + z3) i + (3x2 – z)j+-y)k is irrotational. Also find a scalar function Φ such that = Φ.
Thanks for the update. "Irrotational" means curl = zero, so we compute the curl, set it equal to zero, and solve for the constants.
[tex]\vec f(x,y,z) = (axy+z^3) \, \vec\imath + (3x^2-z) \, \vec\jmath + (bz^2-y) \, \vec k[/tex]
[tex]\nabla \times \vec f(x,y,z) = \left(\dfrac{\partial(bz^2-y)}{\partial y} - \dfrac{\partial(3x^2-z)}{\partial z}\right) \, \vec\imath - \left(\dfrac{\partial(bz^2-y)}{\partial x} - \dfrac{\partial(axy+z^3)}{\partial z}\right) \, \vec\jmath \\ ~~~~~~~~~~~~ + \left(\dfrac{\partial(3x^2-z)}{\partial x} - \dfrac{\partial(axy+z^3)}{\partial y}\right) \, \vec k[/tex]
[tex]\nabla \times \vec f(x,y,z) = 3z^2 \, \vec\jmath + (6-a)x \, \vec k[/tex]
At this point, all we can conclude is that a = 6 to make the k-component vanish. Unfortunately there's no zeroing out the j-component, so the field as given is *not* irrotational.
As I mentioned in comments, if the i-component had instead been [tex]axy+bz^3[/tex], we would have ended up with
[tex]\nabla \times \vec f(x,y,z) = 3bz^2 \, \vec\jmath + (6-a)x \, \vec k[/tex]
in which case we would have b = 0.
I'll continue working with this "fixed" field to find Φ, if only to give you an idea of how to proceed. We want a scalar function Φ(x, y, z) such that the given vector field is the gradient of f. This would entail solving the partial differential equations,
[tex]\dfrac{\partial\Phi}{\partial x} = axy+bz^3 = 6xy[/tex]
[tex]\dfrac{\partial\Phi}{\partial y} = 3x^2 - z[/tex]
[tex]\dfrac{\partial\Phi}{\partial z} = bz^2-y = -y[/tex]
Let's start with the last equation. Integrating both sides with respect to z yields
[tex]\Phi(x,y,z) = \displaystyle \int (-y) \, dz = -yz + g(x,y)[/tex]
Now differentiate both sides with respect to y :
[tex]\dfrac{\partial\Phi}{\partial y} = -z + \dfrac{\partial g}{\partial y} = 3x^2 - z \implies \dfrac{\partial g}{\partial y} = 3x^2[/tex]
Integrate both sides of the latter PDE with respect to y to solve for g :
[tex]g(x,y) = \displaystyle \int 3x^2 \, dy = 3x^2y + h(x)[/tex]
Now we differentiate Φ with respect to x :
[tex]\Phi(x,y,z) = -yz + 3x^2y + h(x) \\\\ \dfrac{\partial\Phi}{\partial x} = 6xy + \dfrac{dh}{dx} = 6xy \implies \dfrac{dh}{dx} = 0[/tex]
Integrate to solve for h :
[tex]h(x) = \displaystyle \int 0 \, dx = C[/tex]
where C is an arbitrary constant.
So the scalar function whose gradient is our "fixed" field f is
[tex]\Phi(x,y,z) = -yz + 3x^2y + C[/tex]
In 1977, the price of a scientific
calculator was $175. In 2004, the
price was $15. Assuming the change
in price was linear, what was the
approximate price of a scientific
calculator in 1998?
First, we need to find how many years are in between 1977 and 2004:
2004-1977 = 27
And the different between the prices:
175-15 = $160
Since this is supposed to be linear, we can do 160/27 which is about 5.925.
We can round this out to be about $6 cheaper per year, or $5.90.

b) Matthew's father has a container that has dimensions that are each double the dimensions of Mathew's container.Matthew thought that the volume would be also double. Is Matthews correct? How many times greater is the volume of the larger container the the volume of the smaller one? Show your work and explain the reasoning. Can someone help ? thanks
When Matthew noticed that the container was one fourth full of sand, the remaining volume quantity needed is 432 inches³.
How to calculate the volume?The container has the following dimensions. 12 in. by 8in. by 6in. Therefore, the volume will be:
= 12 × 8 × 6
= 576 inches.
Since Matthew noticed that the container was one fourth full of sand, the remaining quantity needed will be:
= 576 - (1/4 × 576)
= 576 - 144
= 432 inches³.

X Y
5 -5
6 -6
7 -7
8 -8
Y=___x + ___
Answer:
y = -x +0
Step-by-step explanation:
y = mx + b
y= slope * x + y-intercept
To find slope, use any x and y pair from the table, for example (x= 5, y= -5)
slope = y/x = -5/5 = -1
y= -x + b
To find b the y-intercept, substitute any x and y pair from the table, for example (x= 5, y= -5)
-5 = -5 +b
b = 0
The linear equation that gives the rule for this table is
y = -x + 0 or just y = -x
