Test for relative maxima and minima. Use the second-derivative test, if possible. \[ y=x^{3}-12 x+3 \] Select the correct choice below and, if necessary, fill in the answer box(es) to complete your ch
Answers
In this the correct choice is: D. There are no relative maxima and no relative minima.
The given function is y = \(x^{3}\) - 12x + 3. To find the relative maxima and minima, we need to calculate the first and second derivatives of the function.
First, let's find the first derivative: y' = 3\(x^{2}\) - 12
Now, let's find the second derivative: y'' = 6x
To apply the second-derivative test, we need to determine the critical points by setting the first derivative equal to zero and solving for x:
3\(x^{2}\) - 12 = 0
\(x^{2}\)- 4 = 0
(x - 2)(x + 2) = 0
From this equation, we find that x = 2 and x = -2 are the critical points.
Now, let's evaluate the second derivative at these critical points:
y''(2) = 6(2) = 12
y''(-2) = 6(-2) = -12
Since the second derivative at x = 2 is positive (12 > 0) and the second derivative at x = -2 is negative (-12 < 0), the second-derivative test tells us that there are no relative maxima or minima. Therefore, the correct choice is D. There are no relative maxima and no relative minima for the given function.

Chuck’s Rock Problem: Chuck throws a rock
high into the air. Its distance, d(t), in meters,
above the ground is given by d(t) = 35t – 5t2,
where t is the time, in seconds, since he
threw it. Find the average velocity of the
rock from t = 5 to t = 5.1. Write an equation
for the average velocity from 5 seconds to
t seconds. By taking the limit of the
expression in this equation, find the
instantaneous velocity of the rock at t = 5.
Was the rock going up or down at t = 5? How
can you tell? What mathematical quantity is
this instantaneous velocity?
Answers
The mathematical quantity of the instantaneous velocity is a derivative, specifically the derivative of the distance function d(t) with respect to time.
What mathematical quantity is this instantaneous velocity?To find the average velocity of the rock from t = 5 to t = 5.1, we need to calculate the change in distance and time over this interval.
Change in distance = d(5.1) - d(5) = (35(5.1) - 5\((5.1)^{2}\)) - (35(5) - 5\((5)^{2}\)) ≈ -24.5 m
Change in time = 5.1 - 5 = 0.1 s
Average velocity = (change in distance) / (change in time) ≈ -245 m/s
To find the equation for the average velocity from 5 seconds to t seconds, we need to use the formula for average velocity:
average velocity = (d(t) - d(5)) / (t - 5)
Taking the limit of this expression as t approaches 5 gives us the instantaneous velocity at t = 5:
instantaneous velocity = lim (t→5) [(d(t) - d(5)) / (t - 5)]
Using the given function for d(t), we can evaluate this limit as:
instantaneous velocity = lim (t→5) [(35t - 5\(t^{2}\) - 35(5) + 5\((5)^{2}\) / (t - 5)] = -50 m/s
Since the instantaneous velocity is negative, the rock is going down at t = 5. We can tell this because the velocity is the rate of change of distance with respect to time, and the negative sign indicates that the distance is decreasing with time.
The mathematical quantity of the instantaneous velocity is a derivative, specifically the derivative of the distance function d(t) with respect to time.

With proportional amount=1/3, we can expect 6 of the next 18 desserts sold to be slices of cake.
What is meant by proportion?
In mathematics, proportion is the equality between two ratios. A proportion is a statement of the form "a/b = c/d," where a, b, c, and d are numbers or quantities.
To determine how many of the next 18 desserts sold should be expected to be slices of cake, we need to calculate the proportion of slices of cake sold in the previous sales.
The total number of desserts sold is:
8 + 2 + 5 = 15
The proportion of slices of cake sold is:
5/15 = 1/3
This means that 1/3 of the desserts sold were slices of cake.
To determine how many slices of cake we can expect to be sold out of the next 18 desserts, we multiply the proportion by the total number of desserts:
(1/3) x 18 = 6
Therefore, we can expect 6 of the next 18 desserts sold to be slices of cake.

Jack has twice as many dimes as quarters. If the total value of the coins is $6.30, how many dimes does he have?
Answers
Answer:
Number of dimes = 28
Step-by-step explanation:
Given that:
Worth of coins = $6.30 = 6.30 * 100 = 630 cents
Let,
x be the number of dimes
y be the number of quarters
According to given statement;
x = 2y Eqn 1
10x+25y = 630 Eqn 2
Putting x = 2y in Eqn 2
10(2y) + 25y = 630
20y + 25y = 630
45y = 630
Dividing both sides by 45
\(\frac{45y}{45}=\frac{630}{45}\\y=14\)
Putting y=14 in Eqn 1
x = 2(14)
x = 28
Hence,
Number of dimes = 28

Given the demand function,
Q=54−5P+4PA+0.1Y,
where Q is the quantity of chocolate demanded, P is the price of chocolate, PA is the price of an apple and Y is income, find:
(i) the own price elasticity of demand for chocolate
(ii) the cross price elasticity of demand (
iii) the income elasticity of demand where P=3,PA =2 and Y=100. Comment on the economic significance of your answers.
Answers
The income elasticity of demand is positive, implying that chocolate is a normal good = 0.037
The demand function, Q = 54−5P + 4PA + 0.1Y.
Where Q is the quantity of chocolate demanded, P is the price of chocolate, PA is the price of an apple, and Y is income.
(i) The own-price elasticity of demand for chocolate, we first need to find the expression for it.
The own-price elasticity of demand can be expressed as:
Own-price elasticity of demand = (Percentage change in quantity demanded) / (Percentage change in price)Or,E
P = (ΔQ / Q) / (ΔP / P)E P = dQ / dP * P / Q
Let's calculate the own-price elasticity of demand:
EP= dQ / dP * P / Q= (-5) / (54 - 5P + 4PA + 0.1Y) * 3 / 30
= -0.1667
So, the own-price elasticity of demand for chocolate is -0.1667.
(ii) The cross-price elasticity of demand, we must first determine the expression for it.
The cross-price elasticity of demand can be expressed as:
Cross-price elasticity of demand
= (Percentage change in quantity demanded of chocolate) / (Percentage change in price of apples) Or, E
PA = (ΔQ / Q) / (ΔPA / PA)E PA = dQ / dPA * PA / Q
Let's calculate the cross-price elasticity of demand:
EP = dQ / dPA * PA / Q= (4) / (54 - 5P + 4PA + 0.1Y) * 2 / 30= 0.0296
So, the cross-price elasticity of demand is 0.0296.
(iii) The income elasticity of demand can be expressed as:
Income elasticity of demand = (Percentage change in quantity demanded) / (Percentage change in income)Or,E
Y = (ΔQ / Q) / (ΔY / Y)E Y = dQ / dY * Y / Q
Let's calculate the income elasticity of demand: EY = dQ / dY * Y / Q= (0.1) / (54 - 5P + 4PA + 0.1Y) * 100 / 30
= 0.037
The own-price elasticity of demand is negative, meaning that the quantity demanded of chocolate decreases when the price of chocolate increases.
The cross-price elasticity of demand is positive, indicating that chocolate and apples are substitute goods.

Joe needs to transfer 28 quarts of oil into 7 gallons
Step-by-step explanation:
Joe's error:
28 quarts × 4 quarts/ 1 gallon
= 28 quarts/1 × 4 quarts/ 1 gallon
= (28 × 4)/ ( 1 × 1) = 112 gallons
Correcting Joe's error, we have:
4 quarts = 1 gallon
28 quarts = x
Cross Multiply
4 quarts × x = 28 quarts × 1 gallon
x = 28 quarts × 1 gallon/ 4 quarts
x = 7 gallons
= 28 quarts/x gallons × 1 gallon/4 quarts
= (28 × x)/ ( 1 /4) = 7 gallons
Therefore, Joe needs to transfer 28 quarts of oil into 7 gallons

the parameters in a linear probability model can be interpreted as measuring the change in the probability that y = 1 due to a one-unit increase in an explanatory variable. a. true b. false
Answers
(a) True. The parameters in a linear probability model can be interpreted as measuring the change in the probability that y = 1 due to a one-unit increase in an explanatory variable.
In a linear probability model, the dependent variable (y) takes on binary values, typically 0 or 1, representing two possible outcomes.
The linear probability model assumes a linear relationship between the explanatory variables and the probability of the dependent variable being equal to 1.
The parameters in the linear probability model represent the effects of the explanatory variables on the probability of y being equal to 1.
Specifically, the coefficient associated with an explanatory variable can be interpreted as the change in the probability that y = 1 for a one-unit increase in that variable, holding other variables constant.
For example, if we have a linear probability model with an explanatory variable X and the corresponding coefficient is β, then a one-unit increase in X would lead to a β increase in the probability that y = 1, all else being equal.
However, it's important to note that the linear probability model has certain limitations.
Since probabilities are bounded between 0 and 1, the predicted probabilities from the model may exceed this range.
Additionally, the model assumes constant effects across all levels of the explanatory variables, which may not always hold true in practice.
Despite these limitations, the interpretation of the parameters in a linear probability model as the change in the probability of y = 1 due to a one-unit increase in an explanatory variable is generally valid.
