w = 4 or w=-3.5

Step-by-step explanation:

This likely factors into

(2w  + 7)(w - 4) = 0

in which case there are 2 factors.

2w + 7 = 0

w = - 3.5      or

w - 4 = 0

w = 4

Answer: 45°

Step-by-step explanation: Triangle ABC is similar to EDC, so their corresponding angles are going to be the same. Angle ACB corresponds to angle ECD, so their angles are going to be the same. Since angle ACB is 45°, that means angle ECD is also 45°.

Answer:

We factor the number 16 into prime numbers to get their factors.

We do the same with any given number. Only if it has the same factor as 16 that numberwill be divisible by 16

Both numbers proposed (144&256) are divisible by 16

therefore it is divisible by 16

In the 1984 domestic violence study conducted by Sherman and Berk, the ethical concern was that they potentially withheld a beneficial treatment.

The domestic violence study conducted by Sherman and Berk in 1984 raised an ethical concern in that they financially profited from the research. This raises the question of whether their motives were purely altruistic or whether they were driven by financial gain. Additionally, the study did not adhere to special protections for vulnerable populations such as women and children who may have been victims of domestic violence. This raises concerns about the validity and generalizability of the study's findings. Furthermore, the study potentially withheld a beneficial treatment, which raises questions about the ethical responsibility of researchers to ensure that their subjects receive the best possible care. Finally, there are also concerns that the researchers may have deceived their subjects, which raises questions about the integrity and transparency of the research process. In conclusion, the ethical concerns raised by this study highlight the need for researchers to carefully consider the impact of their research on vulnerable populations and to ensure that they adhere to the highest ethical standards.

The relation "r" on the set of all integers, where x = y^2, is not reflexive.

A relation is reflexive if every element in the set is related to itself. In this case, for the relation x = y^2 to be reflexive, every integer "x" should be related to itself, meaning that x = x^2. However, this is not true for all integers.

For example, if we consider x = 2, it is not equal to 2^2 = 4. Similarly, if we consider x = -3, it is not equal to (-3)^2 = 9.

Since there are integers that do not satisfy the condition x = x^2, the relation x = y^2 is not reflexive on the set of all integers.

The number of hours that the kayak rented for the total costs to be the same will be 2 hours.

At 1 hour, the cost will be:

y = 7x + 9

= 7(1) + 9 = 16

At 2 hours, cost will be:

y = 7x + 9

y = 7(2) + 9

= 23

It should be noted that in the table, at 2 hours the cost is $23 also. Therefore, the number of hours that the kayak rented for the total costs to be the same will be 2 hours.

To calculate 20 percent of the existing field cost, you would need to multiply the field cost by 0.20.

This will give you the amount of the cost that represents 20 percent of the total.

For example, if the existing field cost is $10,000, the calculation would be:
$10,000 x 0.20 = $2,000
20 percent of the existing field cost is $2,000.

To calculate 20 percent of the existing field cost, you can use the following expression:
Existing Field Cost x 0.20 = 20% of Existing Field Cost

Answer:

16 and 18 are two consecutive even numbers that equal 34.

Even numbers starting from zero go: 0,2,4,6,8,10,12,14,16,18,20, and so on...

Answer:

18, 16

Step-by-step explanation:

let the two numbers be x and y

x+y=34→→→→→→equation 1

The difference between any two consecutive even number is 2 therefore

x-y=2→→→→→→equation 2

from equation 1 make x the subject of the formula by taking y to the other side;

x=34-y→→→→→→equation 3

substitute equation 3 as x in equation 2. we have;

34-y-y=2;

34-2y=2;

collect like terms;

-2y=2-34

-2y=-32

divide both sides by -2 we have;

y=16; it is no longer negative because the minus have cancelled each other when dividing

from equation 3;

x=34-y

x=34-16

Answer:

Step-by-step explanation:

Given the profit function P(x) = -6x² +288x -3162, you want to find the value of x and the value of P(x) corresponding to maximum profit.

The vertex of the parabola described by ax²+bx+c lies on the line of symmetry:

  x = -b/(2a)

This will be the value of x that is a maximum when a < 0.

The value of the function at that point can be found by evaluating the quadratic expression for the value of x just found.

Maximum profit is had when ...

  x = -(288)/(2(-6)) = 24

That maximum profit is ...

  P(24) = (-6(24) +288)(24) -3162 = 144(24) -3162 = 294

For maximum profit, 24 tables should be made per day. The maximum profit is $294 per day.

The quotient of 462 and 28 is 16.5 when written in decimal notation.

To calculate this, you divide 462 by 28:

462 ÷ 28 ≈ 16.5

The division process involves dividing the digits of the dividend (462) by the divisor (28) and obtaining the result. In this case, the result is approximately 16.5. The decimal point is placed after the digit 5, indicating the presence of a fractional part.

Please note that this is an approximation because the exact result would involve an infinite decimal expansion, which is typically rounded to a certain number of decimal places for practical purposes.

The probability of the pair of standard dice to be rolled and for their sum to be less than 5 is \(\frac{1}{6}\)

Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.

According to the given problem,

The possible rolls can be represented by ordered pairs,

Where the first entry is the outcome of one die and the second is the outcome of the other.

(1 and 1) , (1 and 2) ,…….,(1 and 6), (2 and 1), (2 and 2),.......,(2 and 6),.....,(6 and 1) ,(6 and 2),....,(6 and 6).

There are 36 possible outcomes when two dice are rolled.

Pairs having sum less than 5: (1 and 1) ,(1 and 2) , (1 and 3) , (2 and 1) , (2 and 2), (3 and 1).

The probability that the sum is less than 5 = \(\frac{6}{36}\)

                                                                       = \(\frac{1}{6}\)

Hence, we can conclude, there is a probability of  \(\frac{1}{6}\) for the standard dice to be rolled and for their sum to be less than 5.

Answer:

((mn^8)/n^9)^3 is m^3 * n^12.

Step-by-step explanation:

To simplify the expression ((mn^8)/n^9)^3, we can apply the exponentiation rules and simplify the numerator and denominator separately.

First, let's simplify the numerator: (mn^8)^3

Using the exponentiation rule for raising a power to a power, we multiply the exponents:

(mn^8)^3 = m^3 * (n^8)^3 = m^3 * n^(8*3) = m^3 * n^24

Now, let's simplify the denominator: n^9

Since we are raising n to the power of 9 and then multiplying it by 3, we can combine the exponents:

n^9 * 3 = n^(9+3) = n^12

Putting it all together, we have:

((mn^8)/n^9)^3 = (m^3 * n^24) / n^12

Now, using the exponentiation rule for dividing powers with the same base, we subtract the exponents:

(m^3 * n^24) / n^12 = m^3 * n^(24-12) = m^3 * n^12

Therefore, the simplified form of the expression ((mn^8)/n^9)^3 is m^3 * n^12.

The actual distances, considering the scale 4 inches = 30 miles, are given as follows:

A. 2 inches = 15 miles.

B. 7 inches = 52.5 miles.

C. 5.5 inches = 41.25 miles.

D. 10 inches = 75 miles.

The scale given is a proportion, which represents the relation between the represented distance and the actual distance.

The scale is given as follows:

4 inches = 30 miles

Meaning that each inch in the drawing represents an actual distance of 7.5 miles, as 30/4 = 7.5.

Then the actual distances for each item, in miles, are found multiplying the given distances in inches by 7.5, which is the scale factor of the scale.

For example, in item a, we have that:

2 inches = 2 x 7.5 = 15 miles.
