Answer: D

Step-by-step explanation:

From the equation given , ( -3)⁰(2x⁻¹y⁻¹)²

Recall :From the laws of indicies,

x⁰ = 1 ,and (xᵃ)ᵇ = xᵃ ˣ ᵇ = xᵃᵇ. and x⁻¹ = 1/ₓ

Therefore,

(-3)⁰ = 1,

( 2x⁻¹y⁻1 )² = 2²x⁻¹ ˣ ²y⁻¹ x ²

= 2²x⁻²y⁻²

=4x⁻²y⁻²

Now going by the law above, the expression will be

=4/ₓ²y²

So the answer is D

Which situation can be modeled by the inequality m > 225? A. The community theater's auditorium can seat at most 225 people.

Georgia [21]

Answer:

<h3>B. The number of people who attended the mathematics conference was more than 225.</h3>

Step-by-step explanation:

Given the inequality m > 225, the inequality means that m is greater than 225. Since the inequality sign does not include equal to sign, then the value of m cannot be less than and equal to 225. The situation that best fits the expression based on the explanation above is "The number of people who attended the mathematics conference was more than 225"

Emphasis should be on 'WAS MORE THAN' according to the statement. The greater sign means that the number of people will always be greater than or more than 225 representing the variable <em>m as the number of people.</em>

The total cost curve shows the cost of total shipment from the different

cities.

a. Please find attached the graph of the total cost to quantity of shipment created with MS Excel.

b. The city that provides the lowest overall cost is; <u>Salt Lake City</u>.

Reasons:

The given parameters are;

The number of shipment per = From 550,000 to 600,000 per year

The given table is presented as follows;

$\begin{tabular}{|l|c|c|c|}Location&Annual Fixed Costs&Variable Cost \\Denver&\$5,000,000&\$4.65 \\Santa Fe&\$4,200,000&\$6.25\\Salt Lake City&\$3,500,000&\$7.25\end{array}\right]$

a. Required:

The plot total cost curve for the locations on a single graph.

Solution:

Please find attached the graph of the total cost curves created with MS Excel

b. Required:

The city that provides the lowest overall cost.

Solution:

The two cities with the lowest overall costs are Denver and Salt Lake City.

From the total cost curve, the area under the curves are;

Area under the curve for Denver;

(7557500 + 7790000) ÷ 2 × 50,000 = 383687500000

Area under the curve for Salt Lake City

(7487500 + 7850000) ÷ 2 × 50,000 = 383437500000

Therefore;

<u>Salt Lake City provides the lowest overall costs</u>.

otez555 [7]

Answer:

Completing the table, we have;

Explanation:

Given the equation;

$y=2x-1$

where y is the output and x is the input.

we were given the outputs 1,3,5.

To get the input for each of the given output let us substitute the output into the equation and solve for x;

$\begin{gathered} \text{for output = 1;} \\ 1=2x-1 \\ 1+1=2x \\ 2=2x \\ x=\frac{2}{2} \\ x=1 \end{gathered}$ $\begin{gathered} \text{for output = 3 ;} \\ 3=2x-1 \\ 3+1=2x \\ 4=2x \\ \frac{4}{2}=x \\ x=2 \end{gathered}$ $\begin{gathered} \text{for output = 5;} \\ 5=2x-1 \\ 5+1=2x \\ 6=2x \\ \frac{6}{2}=x \\ x=3 \end{gathered}$

Therefore, completing the table, we have;
