The required derivative of f(x) = ln(1 - x) is f'(x) = -1 / (1 - x).
What is derivative?A derivative is a two-party contract whose price or value is based on an underlying asset. Futures, options, forward contracts, and swaps are the four most popular types of derivatives. It is a financial instrument whose price and value are determined by the underlying assets.
According to question:The derivative of the natural logarithmic function is given by:
d/dx [ln(u(x))] = 1/u(x) * du/dx
So, to find the derivative of f(x) = ln(1 - x), we need to find the derivative of the inside function, which is 1 - x:
f'(x) = 1/[1 - x] * d/dx [1 - x]
= 1/[1 - x] * (-1)
= -1 / (1 - x)
So the derivative of f(x) = ln(1 - x) is f'(x) = -1 / (1 - x).

How do we calculate cost of each folder and pack of sheets?The system of equations with variables:
C: number of foldersQ: number of packs of sheets
Juan paid 120 pesos for a folder and 2 packages of sheets:
C + 2P = 120
Clearing C:
C = 120 - 2P
Manuel paid 190 pesos for 3 packages of sheets and 2 folders:
2C + 3P = 190
Substituting the "C":
2 * (120 - 2P) + 3P = 190
240 - 4P + 3P = 190
-P = 190 - 240
-P = -50
P = $50

comment savoir si un graphique est proportionnelle ?
Answer:
Pour savoir si un graphique est proportionnel, il faut vérifier si les valeurs de la variable indépendante (l'axe des x) sont proportionnelles aux valeurs de la variable dépendante (l'axe des y). Cela signifie que si on multiplie les valeurs de la variable indépendante par un facteur constant, les valeurs de la variable dépendante seront également multipliées par ce même facteur constant.
Un moyen de vérifier si un graphique est proportionnel est de tracer une ligne droite à travers les points de données. Si tous les points se trouvent sur cette ligne droite, alors le graphique est proportionnel. Si les points ne se trouvent pas sur une ligne droite, alors le graphique n'est pas proportionnel.
Il est également possible de calculer le coefficient de proportionnalité en divisant chaque valeur de la variable dépendante par la valeur correspondante de la variable indépendante. Si le résultat est constant pour toutes les paires de valeurs, alors le graphique est proportionnel.
Enfin, il convient de noter que la proportionnalité n'est qu'un type de relation entre deux variables et que d'autres types de relations peuvent exister, tels que les relations exponentielles, logarithmiques ou quadratiques.

Camden went to the grocery store and purchased cans of soup and frozen
dinners. Each can of soup has 150 mg of sodium and each frozen dinner has
300 mg of sodium. Camden purchased a total of 7 cans of soup and frozen
dinners which collectively contain 1500 mg of sodium. Graphically solve a
system of equations in order to determine the number of cans of soup
purchased, x, and the number of frozen dinners purchased, y.
Camden purchased 4 cans of soup and 3 frozen dinners.
How to solve for thisWe can solve this problem by using a system of two linear equations.
Let x be the number of cans of soup purchased and y be the number of frozen dinners purchased.
Then, based on the information given, we can set up two equations as follows:
150x + 300y = 1500 (the total amount of sodium consumed is 1500 mg)
x + y = 7 (Camden purchased 7 cans of soup and frozen dinners)
Now, we can use either substitution or elimination to find the values of x and y.
Using substitution:
Solve the second equation for y: y = 7 - x
Substitute the expression for y into the first equation: 150x + 300(7 - x) = 1500
Simplify the expression: 150x + 2100 - 300x = 1500
Combine like terms: -150x + 2100 = 1500
Solve for x: -150x = -600
Divide both sides by -150: x = 4
Use the second equation to find y: y = 7 - x = 7 - 4 = 3
So, Camden purchased 4 cans of soup and 3 frozen dinners.

The question is incomplete so, I attached the graph.
what is the definition of opposite rays in geometry
Answer:
Opposite rays point in opposite directions and therefore make a 180-degree angle with each other.
Step-by-step explanation:
A store bought shirts for $5.75 each. If they want
to make 65% profit on selling them what should
the selling price be?
The selling price of a shirt should be $8.97.
What is gain or profit?The profit or gain is equal to the selling price minus the cost price. Loss is equal to the cost price minus the selling price.
Given that, a store bought shirts for $5.75 each and profit percent = 65%.
We know that, Selling price = (100+Profit%)/100 ×CP
Here, Selling price =(100+65)/100 ×5.75
= 1.56×5.75
= $8.97
Therefore, the selling price of a shirt should be $8.97.

25 points! write the radical ³√32m³ using rational exponents
Answer:
To write the radical ³√32m³ using rational exponents:
1. Rewrite the radical using exponential notation: 32m^3 ≈ 8m^3.
2. Convert the exponent into its equivalent fractional form: 8m^3 ≈ 2^3m^3/2^3.
3. Apply a rational exponent to the numerator: (2^3m^3)^(1/3)/2^3 = 2m.
4. The radical can now be written using rational exponents: (2m)^3/2^3.
