The cost per unit actually comes down to 0.8$per unit.

We have given that,

The electricity contract with the utility company is structured so that higher daily energy usage is charged at a lower rate.

The plant’s production processes are performed primarily by robots that are able to work longer hours, when needed, at no additional cost.

Overtime wages were required to produce at levels above 25,000 units.

A cost is an expenditure required to produce or sell a product or get an asset ready for normal use.

The cost of production per unit of the item produced is 1$ as long as the total units produced are less than 2500.

If more than 2500 units are produced then the cost per unit actually comes down to 0.8$per unit.

Answer:

$213.84

Step-by-step explanation:

Think of a rectangle. In the case the length is 6 meters and the width is for meters. To be able to find the area of this rectangle, you need to multiply the length by the width. 6 multiplied by 4 is 24. In the equation it tells you that 1 square meter is $8.91, so now you are trying to figure how much 24 square meters would cost. To figure this out, you will need to multiple 24 by $8.91 giving you $213.84.

Step-by-step explanation:

Answer:

80 m/s

Explanation:

Given:

i) initial velocity (as starts from rest) = 0 m/s

ii) acceleration:  4 m/s²

iii) distance travelled: 800 m

Formula required:

(final velocity)² - (initial velocity)² = 2 × acceleration × distance

Now solve:

v² - 0² = 2 × 4 × 800

v² = 6400

v = √6400

v = 80 m/s

By using a system of equations, we will see that the solution is:

x = 25, y = -50, z = -15

We can write this as a system of equations:

4x + 2y - z = 15

x + y - z = -10

-3x - y + z = 60

Notice that if we add the second and third equations, we get:

(x + y - z) + (-3x - y + z ) = -10 + 60

-2x = 50

x = 50/-2 = -25

So we already got the value of x. Replacing that in the second equation we et:

25 + y - z = -10

Isolating y we get:

y = -10 - 25 + z = z - 35

Now we can replace that in the first equation:

4x + 2y - z = 15

4*25 + 2*(z - 35) - z = 15

100 + z - 70 = 15

z = 15 - 100 + 70 = -15

And using:

y =  z - 35 = -15 - 35 = -50

Then the soution to the matrix equation is:

x = 25, y = -50, z = -15

The Triangle inequality theorem of a triangle says that the sum of any of the two sides of a triangle is always greater than the third side. The correct option is C.

The Triangle inequality theorem of a triangle says that the sum of any of the two sides of a triangle is always greater than the third side.

Suppose a, b and c are the three sides of a triangle. Thus according to this theorem,

 [tex](a+b) > c\\(b+c) > a\\(c+a) > b[/tex]

Given the length of the two sides of the triangle, therefore, we can write the inequalities,

8 + 5 > x  ⇒   13 > x

8 + x > 5  ⇒  x > - 3

5 + x > 8  ⇒  x > 3

Now, as per the inequality the value of x can lie between 3 to 13, but as the side needs to be greatest, therefore, the value of x will be 12.

Hence, the correct option is C.

Interest rate is a proportion of a loan rewarded as interest to the borrower, usually expressed as an annual percent of the current loan.

Answer:

See below

Step-by-step explanation:

An interest rate is basically a percentage of principal charged by the lender for the use of its money, and it is paid via simple interest (usually in an annual period). That principal is the amount of money loaned.

For example, you may have seen a 1.5% annual interest rate, or something like that. This means that if your principal was $5000, let's say, you would have to pay $5000 * 0.015 = $75 in interest per year.

Answer: (-12, 0) and (6, 0)

Step-by-step explanation:

The equation of the parabola is of the form

[tex]y=a(x+3)^2 + 405[/tex]. To find a, we can substitute in the coordinates (0,360).

[tex]360=a(0+3)^2 + 405\\\\360=9a+405\\\\-45=9a\\\\a=-5[/tex]

So, the equation is [tex]y=-5(x+3)^2 + 405[/tex]. Setting this equal to 0,

[tex]-5(x+3)^2 + 405=0\\\\5(x+3)^2 = 405\\\\(x+3)^2 = 81\\x+3=\pm 9\\\\x=-12, 6[/tex]

So, the x-intercepts are (-12, 0) and (6, 0).

The simplest radical form of the expression is [tex]\mathbf{40 ^{2/3}x^{{10}/{3}}y^2}[/tex].

When we have indices in the form [tex]\mathbf{ax^{2/3}}[/tex], we are going to find the cube root of the (ax)². This can be mathematically expressed as:

[tex]\mathbf{=(\sqrt[3]{ax})^2 }[/tex]

From the given information:

[tex]\mathbf{=(8x^55y^3)^{2/3}}[/tex]

[tex]\mathbf{=(\sqrt[3]{8x^55y^3} } )^2[/tex]

[tex]\mathbf{=(\sqrt[3]{40x^5y^3} } )^2[/tex]

[tex]= (\sqrt[3]{40x^5} \times \sqrt[3]{y}^3)^2[/tex]

[tex]\mathbf{= 40 ^{2/3}x^{{5*2}/{3}}y^2}[/tex]
