How do you determine if a function notation is a solution ???? Please give an example
Answer:
Identify the input values.
Identify the output values.
If each input value leads to only one output value, classify the relationship as a function. If any input value leads to two or more outputs, do not classify the relationship as a function.
Step-by-step explanation:
Answer:
Identify the input values. Identify the output values. If each input value leads to only one output value, classify the relationship as a function. If any input value leads to two or more outputs, do not classify the relationship as a function.
Example:
Given f(x) = x2 + 3x – 1, find
a) f(1)
b) f(–1)
c) f(a)
d) f(x – 1)
Solution:
a) f(1) = (1)2 + 3(1) – 1 = 3
b) f(–1) = (–1)2 + 3(–1) – 1 = –3
c) f(a) = a2 + 3a – 1
d) f(x – 1) = (x – 1)2 + 3(x – 1) – 1
= x2 – 2x + 1 + 3x – 3 – 1 = x2 + x –3

Express , twelve times a number minus six is less than or equal to
negative eighteen as an equation
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

Seven oxide thickness measurements of wafers are studied to assess quality in a semiconductor manufacturing process. The data (in angstroms) are: 1264, 1288, 1272, 1304, 1280, 1301, and 1270. Calculate (a) the sample average and (b) sample standard deviation. Round both answers to 1 decimal places.
Answer:
a. Mean = 1,282.7 Angstroms
b. Standard deviation = 15.5
Step-by-step explanation:
a. Firstly, we are told to calculate the sample average. This is same as the mean;
Mathematically that would be;
The value of the sum of terms/ The number of terms.
= (1264 + 1288 + 1272 + 1304 + 1280 + 1301 + 1270)/7 = 8979/7 = 1282.7
b. Standard deviation
Mathematically, this is the square root of variance
= √{(x - mean)^2/N-1}

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?
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

c. From 2005 to 2009, assets decreased and liabilities increased.
d. From 2005 to 2009, assets increased and liabilities decreased.
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.

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?
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

How do you do this problem?
Step-by-step explanation:
∫ t⁷ e^(-t⁴) dt
If x = -t⁴, then dx = -4t³ dt, and ¼ x dx = t⁷ dt.
∫ ¼ x eˣ dx
If u = ¼ x, then du = ¼ dx.
If dv = eˣ dx, then v = eˣ.
∫ u dv = uv − ∫ v du
= ¼ x eˣ − ∫ ¼ eˣ dx
= ¼ x eˣ − ¼ eˣ + C
= ¼ eˣ (x − 1) + C
Substitute back:
= ¼ e^(-t⁴) (-t⁴ − 1) + C
The procedure would be as demonstrated in the attachment(s). As you can see your solution will be,
