Answer:

-27

Step-by-step explanation:

f(x) = 3(x-1)(x-7)

     = (3x-3)(x-7)

     = 3x^2 - 24x + 21

when f(x) = 0, x = 7 or 1

x-intercept of vertix of the graph = (7+1 )/ 2 = 4

f(x) attains it's minimum when x = 4

The minimum output value = 3(4-1)(4-7)  = -27

Given:

Raul's salary

Houston $ 70,000

Los Angeles $ 110,000 ( w 10% state tax)

Requird: actual % salary increase

Solution

Cost of the state tax = 10% ( $110,000) = (0.10) (110000) = $ 11, 000

The state tax will be deducted from his salary in Los Angeles, leaving him with only

$ 110,000 - $11, 000 = $ 99,000

Actual increase in salary = $ 99,000 - $ 70,000 = $ 29,000

% salary increase = ( actual salary increase/ salary in houston)*100 = ( $ 29,000 / $ 70, 000 )*100= 41.4%

Step-by-step explanation:

1/3(9x+3)=3x+1 multiply inside the parenthesis with 1/3

(9x+3)/3 = 3x + 1 multiply both sides of the equation by 3

9x + 3 = 9x + 3 add like terms

0 = 0 which means there are infinitely many solutions for this equation therefore infinitely many values for x

Answer:

x is any number

infinite solutions

Step-by-step explanation:

1/3(9x+3)=3x+1

Distribute

3x+1 = 3x+1

Subtract 3x from each side

1=1

Since this is always true, x can be any value

Answer:

The time it would take to inflate the balloon to approximately two-thirds of its maximum volume is approximately 46.90 minutes

Step-by-step explanation:

The given parameters are;

The diameter of  the balloon  = 55 feet

The rate of increase of the radius of the balloon when inflated = 1.5 feet per minute

We have;

dr/dt = 1.5 feet per minute = 1.5 ft/min

V = 4/3·π·r³

The maximum volume of the balloon = 4/3 × 3.14 × 55³ = 696556.67 ft³

When the volume is two-thirds the maximum volume, we have;

2/3 × 696556.67 ft³ = 464371.11 ft³

The value of the radius, r₂ at that point is found as follows;

4/3·π·r₂³ = 464371.11 ft³

r₂³ = 464371.11 ft³ × 3/4 = 348278.33 ft³

348278.333333

r₂ = ∛(348278.33 ft³) ≈ 70.36 ft

The time for the radius to increase to the above length = Length/(Rate of increase of length of the radius)

The time for the radius to increase to the above length ≈ 70.369 ft/(1.5 ft/min) ≈ 46.90 minutes

The time it would take to inflate the balloon to approximately two-thirds of its maximum volume ≈ 46.90 minutes.

The probability that a package of 5 tasks is processed in less than 8 minutes is 0.963.

Let X denote the time required to process a package of five tasks. X is an exponentially distributed random variable with mean 2 minutes.

The probability of X being less than 8 minutes is given by:

P(X ≤ 8) = 1 - P(X > 8)

= \(1 - (1 - e^{(-8/2)}^{5}\)

= 0.963

Therefore, the probability that a package of 5 tasks is processed in less than 8 minutes is 0.963.

(a) To show that there can be at most 14 abundant circles, we can use the combination formula.

(b) There cannot be 14 abundant circles.

To see why, consider that each circle contains 4 points. If there were 14 abundant circles, then there would be a total of 14 * 4 = 56 points involved.

Since a circle abundant if it passes through at least 4 points of S, we can select any 4 points from the set S to form a circle. The number of ways to choose 4 points out of 8 is given by the combination formula:

C(8, 4) = 8! / (4!(8-4)!) = 70

Therefore, there can be at most 70 abundant circles.

However, this count includes some cases where multiple circles pass through the same 4 points. To eliminate these duplicates, we can consider the maximum number of unique sets of 4 points that can form abundant circles.

(b) There cannot be 14 abundant circles.

To see why, consider that each circle contains 4 points. If there were 14 abundant circles, then there would be a total of 14 * 4 = 56 points involved. However, we are given that the set S has only 8 points. Therefore, it is not possible to have 14 abundant circles.

The maximum number of abundant circles can be determined by considering the maximum number of unique sets of 4 points. Since there are C(8, 4) = 70 unique sets of 4 points, the maximum number of abundant circles is 70.

Given the parameter values n, δ, A₀, and k₀, the endogenous technological progress A(t) can be calculated using a recursive formula. The value of physical capital k(t) can also be determined using a separate recursive formula. The specific values depend on additional parameters not provided.

To compute the value of the endogenous technological progress A(t) at time t, we can use the following recursive formula:

A(t+1) = (1 - δ) * A(t) + n * k(t)^θ

where:

- A(t) represents the value of technological progress at time t.

- δ is the depreciation rate, which is 0.1 in this case.

- n is the exogenous growth rate of technological progress, which is 0.01 in this case.

- k(t) is the value of physical capital at time t.

- θ is the elasticity of output with respect to capital, which is not provided in the given information.

To compute k(t), we can use the following formula:

k(t+1) = (1 - δ) * k(t) + i(t)

where:

- k(t) represents the value of physical capital at time t.

- δ is the depreciation rate, which is 0.1 in this case.

- i(t) is the investment at time t.

Since the investment i(t) is not given in the provided information, we cannot determine the exact values of A(t) and k(t) for each time period. However, we can use the given initial values to compute their values for the initial time period (t = 0).

Using the provided initial values:

A(0) = 5

k(0) = 10

We can substitute these values into the recursive formulas to compute A(1) and k(1):

A(1) = (1 - 0.1) * 5 + 0.01 * 10^θ

k(1) = (1 - 0.1) * 10 + i(0)

The values of A(1) and k(1) can then be used to compute A(2) and k(2), and so on, by iteratively applying the recursive formulas. The specific values of A(t) and k(t) for each time period would depend on the values of θ and the investment i(t), which are not provided.

Step-by-step explanation:

The quantified statement (∃x)¬D(x) can be translated into simple, everyday English as "There exists a penguin that is not dangerous."

The quantified statement (∃x)¬D(x) can be further explained in the context of penguins. Let's break it down:

The symbol (∃x) denotes the existence of an object or entity that satisfies a certain condition. In this case, it refers to a penguin that meets the condition specified afterward.

The predicate ¬D(x) can be understood as the negation of the predicate D(x), where D(x) represents the statement "x is dangerous." The negation symbol (¬) in front of D(x) indicates the opposite or negation of the statement.

Combining these elements, the quantified statement (∃x)¬D(x) asserts that there is at least one penguin for which the predicate "is not dangerous" holds true. In everyday English, this statement can be translated as "There exists a penguin that is not dangerous."

Essentially, it implies that within the domain of all penguins being considered, at least one penguin can be found that is not considered dangerous. This quantified statement allows for the possibility that not all penguins are dangerous and acknowledges the existence of non-threatening penguins.

A certain bacteria strain needs 4 hours to double its population. If in the beginning there are 45 bacteria, after 1 day, the number of bacteria present is 2,880, after 2 days, the number of bacteria is 184,320, after 3 days, the number of bacteria is 11,796,480.

The problem can be solved using the exponential growth model.

In the given problem, the formula for the growth model is given, that is:

f(x) = 45 (64)^(x)

Where:

f(x) = total number of bacteria present after x days

To find f(x) for 1 day, 2 days, and 3 says, substitute x = 1, x = 2, and x = 3 into the formula.

f(1) = 45 (64)¹ = 2,880

f(2) = 45 (64)² = 184,320

f(3) = 45 (64)³ = 11,796,480

Hence,

after 1 day, the number of bacteria present is 2,880, after 2 days, the number of bacteria is 184,320, after 3 days, the number of bacteria is 11,796,480.

It is an inferential technique that uses the data from a sample to draw inferences about a population.

Hypothesis testing is a type of statistical hypothesis that uses data from a sample to draw judgments about a population parameter or a population probability distribution.

First, an uncertain hypothesis is made about the parameter or distribution. This is named the null hypothesis and is denoted by \(H_{O}\). An alternative hypothesis (denoted \(H_{a}\)), which is the opposite of the null hypothesis, is then described.

The hypothesis-testing process involves using sample data to decide whether or not \(H_{0}\) can be rejected. If \(H_{O}\) is rejected, the statistical determination is that the alternative hypothesis \(H_{a\) is true.
