What is the value of g-1(7)

Answer:

D 7x -28 i think it is like this

The domain of the function f(x) = -3x + 2 is (-∞, +∞), representing all real numbers, and the range is (-∞, 2], representing all real numbers less than or equal to 2.

The function f(x) = -3x + 2 is a linear function defined by a straight line. To determine the domain of this function, we need to identify the range of values for which the function is defined.

The domain of a linear function is typically all real numbers unless there are any restrictions. In this case, there is no explicit restriction mentioned, so we can assume that the function is defined for all real numbers.

Therefore, the domain of the function f(x) = -3x + 2 is (-∞, +∞), which represents all real numbers.

Now, let's analyze the range of the function. The range of a linear function can be determined by observing the slope of the line. In this case, the slope of the line is -3, which means that as x increases, the function values will decrease.

Since the slope is negative, the range of the function f(x) = -3x + 2 will be all real numbers less than or equal to the y-intercept, which is 2.

Therefore, the range of the function is (-∞, 2] since the function values cannot exceed 2.

Step-by-step explanation:

\(\frac{1}{3} * 3 * (2x - 5) = \frac{1}{2} * 2 * (5x - 2)\\= > 2x - 5 = 5x - 2\\= > 3x = -3\\= > x = -1\)

Answer:

Let c be the number of cows and h the number of chickens (hens). There are 65 heads so

c + h = 65.

Each cow has 4 legs, each hen has 2 legs and there are 226 legs in total so

4c + 2h = 226.

Multiply both sides of the first equation by 2 and subtract it from the second equation to get

2c = 96 and thus c = 48.

From the first equation it then follows that h = 65 - 48 = 17.

Answer:

The sequence is increasing by 5 at each step. So, we can write:

a1 = 30

a2 = 30 + 5 = 35

a3 = 30 + 25 = 40

a4 = 30 + 35 = 45

a5 = 30 + 4*5 = 50

We notice that the nth term is given by:

an = 30 + (n-1)5

So, the explicit formula for the nth term is:

an = 25n + 5

The unknown number, represented by the variable b, is 1/2, which satisfies the equation "Five more than the product of a number and 8 equals 9."

To solve the equation "Five more than the product of a number and 8 equals 9" using the variable b for the unknown number, we can express this statement as an equation:

8b + 5 = 9

To solve for b, we need to isolate the variable on one side of the equation. Let's simplify the equation step by step:

Subtract 5 from both sides to get rid of the constant term:

8b + 5 - 5 = 9 - 5

8b = 4

Divide both sides of the equation by 8 to solve for b:

8b/8 = 4/8

b = 1/2

Therefore, the solution to the equation is b = 1/2. This means that when we substitute b = 1/2 into the equation, the equation will hold true:

8(1/2) + 5 = 9

4 + 5 = 9

Both sides of the equation are equal, confirming that b = 1/2 is the solution.

The value of the given expression will be 2.

The given expression is \(\frac{64^{0.5} }{4^{0.5} }\)

64 and 4 are perfect squares,

Perfect squares: A perfect square is a number that can be written as the second exponent of an integer or as the product of an integer by itself. For instance, the number 64 is a perfect square since it is the product of the integer 8 multiplied by itself, 8*8 = 64

64 is a perfect square of 8 and 4 is the perfect square of 4.

Now, writing 64 as \(8^{2}\) and 4 as \(2^{2}\) , the expression will be

\(\frac{64^{0.5} }{4^{0.5} } = \frac{8^{2*0.5} }{4^{2*0.5} } = (\frac{8}{4})^{1} = 2\)

The total weight of the liquid in the tank is approximately 12,628 pounds.

To calculate the weight of the liquid, we need to determine the volume of the hemisphere and then multiply it by the density of the liquid. The formula for the volume of a hemisphere is V = (2/3)πr³, where r is the radius of the hemisphere.

In this case, the diameter of the tank is given as 24 feet, so the radius is half of that, which is 12 feet. Plugging this value into the formula, we get V = (2/3)π(12)³ ≈ 904.78 cubic feet.

Finally, we multiply the volume by the density of the liquid: 904.78 cubic feet * 92.5 pounds per cubic foot ≈ 12,628 pounds. Therefore, the total weight of the liquid in the tank is approximately 12,628 pounds.

In summary, to calculate the weight of the liquid in the tank, we first determine the volume of the hemisphere using the formula V = (2/3)πr³. Then, we multiply the volume by the density of the liquid.

By substituting the given diameter of 24 feet and using the appropriate conversions, we find that the total weight of the liquid is approximately 12,628 pounds.

An account's receivable subsidiary ledger  is an accounting ledger that shows the transaction and payment history of each customer to whom the business extends credit.

The area of the square with a side length of 3.1 meters is 9.61 square meters.

To find the area of a square, we need to multiply the length of one side by itself. In this case, the square has a side length of 3.1 m.

Area of a square = side length × side length

Substituting the given side length into the formula:

Area = 3.1 m × 3.1 m

To perform the calculation:

Area = 9.61 m²

It's worth noting that when calculating the area, we are working with squared units. In this case, the side length is in meters, so the area is expressed in square meters (m²). The area represents the amount of space enclosed within the square.

Remember, to find the area of any square, you simply need to multiply the length of one side by itself.

To find the interquartile range (IQR) of the given data set, we first need to find the first and third quartiles (Q1 and Q3).

Arrange the data set in ascending order:

23, 32, 34, 39, 43, 48, 67, 76, 84, 93

Find the median of the entire data set:

Median = (43 + 48)/2 = 45.5

Divide the data set into two halves: the lower half (L) and the upper half (U). If the median value is included in the data set, we exclude it from both halves.

L: 23, 32, 34, 39, 43

U: 67, 76, 84, 93

Find the median of the lower half (L) and upper half (U) separately to find Q1 and Q3:

Q1 = median of L = (32 + 34)/2 = 33

Q3 = median of U = (76 + 84)/2 = 80

Calculate the IQR by subtracting Q1 from Q3:

IQR = Q3 - Q1 = 80 - 33 = 47

Therefore, the interquartile range (IQR) of the given data set is 47.

The probability that at least 2 students feel like they can do better in their math class is E. 0.9130.

To find the probability that at least 2 students feel like they can do better, we need to calculate P(X >= 2). This can be done using the cumulative distribution function (CDF) of the binomial distribution:

P(X >= 2) = 1 - P(X < 2) = 1 - P(X = 0) - P(X = 1)

Using the binomial probability formula, we can calculate:

P(X = 0) = (5 choose 0) * 0.6^0 * 0.4^5 = 0.01024

P(X = 1) = (5 choose 1) * 0.6^1 * 0.4^4 = 0.07680

Therefore,

P(X >= 2) = 1 - 0.01024 - 0.07680 = 0.91296

Rounding this to four decimal places, we get: 0.9130

Therefore, the answer is option E: 0.9130.

In Mathematics and Geometry, a piecewise-defined function simply refers to a type of function that is defined by two (2) or more mathematical expressions over a specific domain.

Generally speaking, the domain of any piecewise-defined function simply refers to the union of all of its sub-domains. By critically observing the graph of this piecewise-defined function, we can reasonably infer and logically deduce that it is constant over several intervals or domains such as x > 2 and x < -2.

In conclusion, this piecewise-defined function has a removable discontinuity.
