Answer:
Hyperbola
Step-by-step explanation:
Consider [tex]x=k.[/tex]
Substitute [tex]x=k[/tex] in given equation [tex]x^2+y^2-z^2=81[/tex]
[tex]k^2+y^2-z^2=81[/tex]
[tex]\Rightarrow y^2-z^2=9^2-k^2[/tex]
[tex]\Rightarrow y^2-z^2=(9-k)(9+k)[/tex]
Here, different orientation for [tex]-9<k<9[/tex] then [tex]-9<k[/tex] or [tex]k<9.[/tex]
Hence, the surface equation represents a trace of the hyperbola.

Answer:
A. From 2005 to 2009, both assets and liabilities decrease.
Step-by-step explanation:
I just took the test and it was correct
From 2005 to 2009, both Assets and Liabilities decreased.
We have - A table showing the assets and liabilities of smith family in year 2005 and 2009.
We have to estimate, whether the smith family has acquired more assets or liabilities from the year 2005 to 2009.
What do you understand by Assets and Liabilities?Assets are the items that an individual own in order to extract some economic benefit from it in the future.
Liability includes the money, services or items that you owe to other person. Example : Loan, mortgage etc.
In the question given -
Assets are : Home value, Car value, boat value.Liabilities are : Car loan, Mortgage, Equity loan, personal loan.In the year 2005 :
Assets : $2,25,000.Liabilities : $38,000.In the year 2009 :
Assets : $2,18,000.Liabilities : $23,000.Hence, it can be seen from the above figures that - From 2005 to 2009, both Assets and Liabilities decreased.

Aaron tracks the time it takes him to mow lawns by writing coordinate points relating x, the time in hours it takes to mow a lawn, and y, the area of land mowed in acres. Two of his points are (3, 1.5) and (5, 2.5). Which statement describes the slope of the line through these two points? It takes Aaron about 1 hour to mow 2 acres. Aaron’s rate for mowing lawns is 0.5 acres per hour. The ratio of acres to time is 5 acres to 3 hours. The rate to mow a lawn is 0.6 hours per acre.
Answers
Answer: Aaron’s rate for mowing lawns is 0.5 acres per hour
Step-by-step explanation:
Hope this helps!!
The statement "The rate to mow a lawn is 0.5 acres per hour" correctly describes the slope of the line passing through the given points.
We have,
To determine the slope of the line passing through the points (3, 1.5) and (5, 2.5), we can use the slope formula:
Slope = (change in y) / (change in x)
Given the two points, we can calculate the change in y and the change in x:
Change in y = 2.5 - 1.5 = 1
Change in x = 5 - 3 = 2
Plugging these values into the slope formula:
Slope = 1 / 2 = 0.5
The slope represents the rate of change of the y-coordinate (area) with respect to the x-coordinate (time).
In this case, a slope of 0.5 means that for every hour it takes Aaron to mow a lawn (change in x), the area mowed (change in y) increases by 0.5 acres.
Therefore,
The statement "The rate to mow a lawn is 0.5 acres per hour" correctly describes the slope of the line passing through the given points.

Complete the graduated commission problem: You earn 20%
commission on the first $500 of sales, 25% commission on the next
$1000 of sales, and 30% commission on all sales over $1500. If you sold
$1940, what is your total commission?
Answers
Answer: I'll give you both the percentage and dollar amount. 75% = $144
Step-by-step explanation: first, I added up all the percentages to total 75%. then I took the total sales, and divided that by .75 (75% in decimal form), so:
1940 x .75 = 1455
1940 - 1455 = 144
Juan baked 5 dozens of cupcakes which cost her a total of PHP 2675.How much should she sell each cupcake if she wants to get a 25% profit?
Answers
Step-by-step explanation:
5 cupcakes = PHP 2675
25% profit =
25/100 × 2675 = 668.75
Selling price for 25% profit = 2675 + 668.75 = 3343.75
Cost of each cupcake for 25% profit = 3343.75/5
= 668.75

Express , twelve times a number minus six is less than or equal to
negative eighteen as an equation
Answers
Answer:
12x - 6 ≤ - 18
Step-by-step explanation:
We will call "a number" x so
Twelve times a number would be:
12x
Then minus 6
12x - 6
Now we add the less than or equal to sign.
12x - 6 ≤
This is equal to negative eighteen, so:
12x - 6 ≤ - 18
As a bonus we can also solve for x.
12x - 6 = - 18 Add 6 to each side.
12x - 6 + 6 = -18 + 6
12x = -18 + 6
12x = -12 Divide each side by 12
12x/12 = -12/12
x = -12/12
x = -1
So we can say when x ≤ -1 Then 12x - 6 ≤ -18
