Answer:

Step-by-step explanation:

It looks like you're given the equations ...

6px^3 = 3x^6p

Dividing both sides by 3px^3, we get ...

2 = x^3

Substituting that into the left side of the equation, we have ...

6px^3 = 12p

It appears this is the expression you want on the right.

6px^3 = 3x^6p = 12p

A manufacturing company builds construction machinery. It sells 10 machines for $18,100 and 20 machines for $26,600. Which equat

Anon25 [30]

<h3>Answer:</h3>

D. R(x) = 850x +9600

<h3>Step-by-step explanation:</h3>

Selling 10 more machines increased revenue from $18100 to $26600, an increase of ...

... $26,600 -18,100 = $8,500

That is, the revenue increased by $8500/10 = $850 per machine.

Only one answer choice has this number in it:

... D. R(x) = 850x+9600

_____

<em>Check</em>

R(10) = 850·10 +9600 = 8500 +9600 = 18,100 . . . . OK

R(20) = 850·20 +9600 = 17000 +9600 = 26,600 . . . . OK

<em>Comment on answer selection</em>

On multiple-choice questions, it is rarely necessary to work out the solution to the problem completely. Usually, it is sufficient to find the one number that discriminates between correct and incorrect answers.

In real life, answers are rarely multiple-choice. You are required to work the problem completely and to figure out how to tell if your answer is correct.

Here, we have worked the problem far enough to find the slope, the amount by which revenue increases when sales increases by 1 unit. The intercept can be found different ways. One of them is to see what number makes the revenue match for one of the "x" values:

... R(10) = 850·10 +b = 18100

... b = 18100 -8500 = 9600

so ...

... R(x) = 850x +9600

We can check this answer by computing R(20), as we have above.

Wyoming's population is 5x10(to the power of 5) While Colorado's population is 5,000,000. How can you complete this sentence? Wy

adelina 88 [10]

Wyoming’s population is equals to:
=> 5 x 10^5
Colorado’s population is equals to
=> 5 000 000
Now, we need to find the answer which population is greater. First, let’s solve the Wyoming’s population:
=> 5 x 10^5
=> 5 x (10 x 10 x 10 x 10 x 10)
=> 5 x 100 000
=> 500 000
=> Colorado vs Wyoming = 5 000 000 vs 500 000
Thus, Wyoming population is 0.1 times the population of Colorado.
=> 5 000 000 x 0.1 = 500 000

Which is correct?

Alja [10]

Below is the conversion table for letter A to D:
1 deciliter = 0.001 hectoliters
1 liter = 100 centiliters
1 kilolieter = 10 hectoliter
1 liter = 10 deciliter

The correct one would be letter C - There are 6.8 kiloliters in 68 hectoliters. Since 1 kiloliters (kl) is equal to 10 hectoliters (hl), 6.8 kl times 10 is equal to 68 hl.

HELP!<br> Which is the inverse of this matrix?

malfutka [58]

Answer:

$\text{\bf{A.}}\qquad\left[\begin{array}{ccc}-19&9&-7\\15&-7&6\\-2&1&-1\end{array}\right]$

Step-by-step explanation:

Many scientific and graphing calculators will compute this easily.

The inverse of a square matrix is a square matrix of the same dimensions. That eliminates choices C and D. We can check choices A and B by computing a couple of terms of the product of the given matrix and its "inverse". That product should be the identity matrix, with 1 on the diagonal and 0 elsewhere.

Using matrix A,

(r, c) = (1, 1) = 1(-19) +2(15) +5(-2) = -19 +30 -20 = 1 . . . . correct

(r, c) = (2,3) = 3(-7) +5(6) +9(-1) = -21 +30 =9 = 0 . . . . correct

Using matrix B,

(r, c) = (1, 1) = 1(-19) +2(-2) +5(15) = -19 -4 +75 = 52 . . . . incorrect

Indications are that choice A is appropriate.
