Answer: f(x) is -74(x+1/7)^(-1/2)
Step-by-step explanation:
To find the derivative of f(x), we can use the power rule and the chain rule.
First, let's rewrite f(x) as:
f(x) = -148(x+1/7)^(1/2)
Now, we can apply the power rule:
f'(x) = -148 * (1/2) * (x+1/7)^(-1/2)
Finally, we can use the chain rule:
f'(x) = -148 * (1/2) * (x+1/7)^(-1/2) * 1
f'(x) = -74(x+1/7)^(-1/2)
Therefore, the derivative of f(x) is -74(x+1/7)^(-1/2).
The mug is 5/8 full, the mug contains 3/4 of water find the capacity of the mug
The capacity of the mug is 1.2. The capacity of the mug can be found by using the equation C = (3/4) ÷ (5/8).
What is capacity?It is the maximum amount of output that can be produced in a given period of time. Capacity is usually expressed in terms of units per unit of time, such as gallons per minute or passengers per hour.
In this equation, 3/4 represents the amount of water in the mug, and 5/8 represents the amount the mug is full.
Let the capacity of the mug be x.
Given,
Mug is 5/8 full and contains 3/4 of water
So, 5/8 of the mug is filled with water
Therefore,
5/8 of x = 3/4
(5/8 )x = (3/4)
x = (3/4) × (8/5)
x = (24/20)
x = 1.2
Therefore, the capacity of the mug is 1.2.

Decompose and find the area of the composite figure
The composite figure has a total area of 102 square units (80 + 16 + 6 square units). Consequently, the composite figure has a 102 square unit area.
How can you calculate a composite figure's entire surface area?Composite things that are three dimensional (3D) are constructed from two or more separate pieces. Finding each item's outside surface area and adding the surface areas together will yield the surface area of a 3D composite object. Another way to divide it is into a top and a bottom.
We may divide the composite figure into smaller forms and sum up their areas to determine the area of the overall figure. Here is one method for breaking down the figure:
A rectangle and two triangles make up the figure.
The rectangle has an area of 80 square units since it is 10 units long and 8 units wide.
The two triangles have right triangles with four and six unit-long legs, respectively. The equation (base * height) / 2 may be used to calculate each triangle's area.
The area of the triangle on the left is (4 * 8) / 2 or 16 square units since its base is 4 units and its height is 8 units (the length of the rectangle).
The area of the triangle on the right is (6 * 2) / 2 or 6 square units because its base is 6 units and its height is 2 units (the distance between the bottom of the triangle and the bottom of the rectangle).

, where V is the value of the account in t years, P is the principal initially invested, e is the base of a natural logarithm, and r is the rate of interest, determine the amount of money, to the nearest cent, in the account after 13 years.
The nearest cent, the amount of money in the account after 13 years is $2,094.18.
The formula for continuous compound interest is:
V = Pe^(rt)
where V is the value of the account after t years, P is the principal (initial amount) invested, e is the base of natural logarithms (approximately 2.71828), r is the annual interest rate (as a decimal), and t is the time period in years.
In this case, P = $741, r = 0.058 (since the annual interest rate is 5.8%), and t = 13. Substituting these values into the formula, we get:
V = 741e^(0.058*13)
Using a calculator, we can evaluate e^(0.058*13) to be approximately 2.8302. Then, we can multiply this value by 741 to get:
V = 741*2.8302
V ≈ $2,094.18
Therefore, to the nearest cent, the amount of money in the account after 13 years is $2,094.18.

For the cost and price functions below, find a) the number, q, of units that produces maximum profit; b) the price, p, per
unit that produces maximum profit; and c) the maximum profit, P.
C(q) = 70+ 15q; p=63-2q
a) The number, q, of units that produces maximum profit is q =
b) The price, p, per unit that produces maximum profit is p = $
c) The maximum profit is P = $
a) The number of units that produces maximum profit is q = 12.
b) The price per unit that produces maximum profit is p = $39.
c) The maximum profit is P = $386.
What is profit?
a) To find the number of units that produces maximum profit, we need to find the point where revenue equals cost. The revenue function is given by:
R(q) = pq = (63-2q)q = 63q - 2q²
The cost function is given by:
C(q) = 70 + 15q
The profit function is given by:
P(q) = R(q) - C(q) = (63q - 2q²) - (70 + 15q) = -2q² + 48q - 70
To find the number of units that produces maximum profit, we take the derivative of the profit function with respect to q, and set it equal to zero:
P'(q) = -4q + 48 = 0
Solving for q, we get:
q = 12
Therefore, the number of units that produces maximum profit is q = 12.
b) To find the price per unit that produces maximum profit, we substitute q = 12 into the price function:
p = 63 - 2q = 63 - 2(12) = 39
Therefore, the price per unit that produces maximum profit is p = $39.
c) To find the maximum profit, we substitute q = 12 and p = 39 into the profit function:
P = -2q² + 48q - 70 = -2(12)² + 48(12) - 70 = $386
Therefore, the maximum profit is P = $386.

The salaries did not rise with inflation. The butter is now 25% costlier. By what percentage should a housewife reduce the consumption, so that her expenditure stays the same
The percentage of reduction in consumption required to keep the same expenditure is 25%.
What is Inflation?Inflation is an economic phenomenon that occurs when the prices of goods and services increase over time.
To find out the percentage of reduction in consumption, we need to calculate the difference between the current and the original prices of the butter.
This can be done by subtracting the original price of the butter from the current price of the butter (25% costlier).
The difference can be expressed as a percentage by dividing the difference by the original price.
Therefore, the percentage of reduction in consumption required to keep the same expenditure is 25%.
This means that a housewife needs to reduce her consumption of butter by 25% in order to keep her expenditure the same.
Thus, the percentage of reduction in consumption required to keep the same expenditure is 25%.

Answer: x = -1 and y = 9
Step-by-step explanation:
To solve this system of equations, we can use the substitution method.
First, solve the first equation for y:
y = -x + 8
Now, substitute this expression for y into the second equation and solve for x:
4x + y = 5
4x + (-x + 8) = 5 (substituting -x + 8 for y)
3x + 8 = 5
3x = -3
x = -1
Now that we have found the value of x, we can substitute it back into one of the original equations to solve for y. Let's use the first equation:
y = -x + 8
y = -(-1) + 8
y = 9
Therefore, the solution to the system of equations is x = -1 and y = 9.

For fau/cet filter:
The break-even point in unit sales is 28,571 units.The break-even point in dollar is $2,571,390.For pitcher-filter:
The break-even point in unit sales is 22,222 units.The break-even point in dollar is $2,444,420.How do we calculate breakeven point in unit sales and dollars?Let's start with the fau/cet model:
Contribution margin per unit = selling price - variable cost
Contribution margin per unit = $90 - $25
Contribution margin per unit = $65
Contribution margin ratio = contribution margin per unit / selling price
Contribution margin ratio = $65 / $90
Contribution margin ratio = 0.722
The sales mix is 2 faucet models for every 3 pitcher filters sold, so the contribution margin weighted average is:
= (2/5)($65) + (3/5)($90-$20)
= $42
Now we can calculate the break-even point in units for the faucet model:
= Total fixed costs / contribution margin per unit
= $1,200,000 / $42
= 28,571 units
For pitcher filter:
Contribution margin per unit = selling price - variable cost
Contribution margin per unit = $110 - $20
Contribution margin per unit = $90
Contribution margin ratio = contribution margin per unit / selling price
= $90 / $110
Contribution margin ratio = 0.818
Contribution margin weighted average:
= (2/5)($25) + (3/5)($90-$20)
= $54
Break-even point in units for pitc/her filter:
= Total fixed costs / contribution margin per unit
= $1,200,000 / $54
= 22,222 units
Break-even point in dollars for fau/cet model:
= 28,571 units x $90 per unit
= $2,571,390
Break-even point in dollars for pitc/her-filter:
= 22,222 units x $110 per unit
= $2,444,420

The volume of a cuboid is 108cm3.
The length is 4cm and the width is 9cm.
Work out the height of the cuboid.
Answer:
You can use the formula for the volume of a cuboid, which is Volume = length x width x height
You are given the volume of the cuboid as 108cm^3, the length as 4cm, and the width as 9cm. Let's substitute these values into the formula and solve for the height:
108cm^3 = 4cm x 9cm x height
To solve for height, you can divide both sides by 36 (which is equal to 4cm x 9cm) to isolate height:
108cm^3 ÷ 36 = 4cm x 9cm x height ÷ 36
3cm = height
So the height of the cuboid is 3cm.

SOLVE LAW OF INDICES
Answer:
To solve this problem, we can use the laws of indices, specifically the law that states that (a^m)^n = a^(m*n).
So, we have:
(1/64)^(2/3) = (1^(2/3))/(64^(2/3))
Since any number raised to the power of 1 is itself, we can simplify the numerator to just 1.
Now, we have:
(1/64)^(2/3) = 1/(64^(2/3))
To evaluate 64^(2/3), we can use the law of indices again, which states that a^(1/n) = nth root of a. In this case, we have:
64^(2/3) = (64^(1/3))^2 = 4^2 = 16
So, substituting this back into the original expression, we have:
(1/64)^(2/3) = 1/16
Therefore, (1/64)^(2/3) simplifies to 1/16.
Step-by-step explanation:
Answer:
Using the law of indices, we have:
(1/64)^(2/3) = (1^(2/3))/(64^(2/3))
Now we need to simplify the denominator by finding the cube root of 64:
64^(1/3) = 4
Substituting this value in the original expression, we get:
(1/64)^(2/3) = (1^(2/3))/(4^2)
Simplifying further, we have:
(1/64)^(2/3) = 1/16
