Basically you would move down the number line until you get to -8c and count how much you moved.

The maximum revenue possible in this situation is 15625/A dollars, where A is the coefficient in the quadratic equation.

To find the maximum revenue possible in this situation, we can use the concept of vertex or the vertex form of a quadratic equation.

The revenue equation is given by R = -Ax^2 + 250x, where A is a constant coefficient.

The maximum revenue occurs at the vertex of the parabolic curve represented by the equation. The x-coordinate of the vertex can be found using the formula x = -b / (2a), where a and b are the coefficients of the quadratic equation.

In this case, a = -A and b = 250. Plugging in these values, we get:

x = -250 / (2 * (-A))

= 125 / A

To find the maximum revenue, we substitute this value of x into the revenue equation:

R = -A * (125 / A)^2 + 250 * (125 / A)

= -A * (15625 / A^2) + (31250 / A)

= -15625 / A + 31250 / A

= 15625 / A

The maximum revenue is given by 15625 / A. The value of A is not specified in the question, so we cannot determine the exact maximum revenue without knowing the value of A. However, we can say that the maximum revenue increases as A decreases.

The volume of the volleyball is  6,367.4 cm³

For a sphere of radius R, the circumference is:

C = 2*3.14*R

and the volume is:

V = (4/3)*3.14*R³

Here the circumfernce is 72.2cm, then we can write:

72.2cm = 2*3.14*R

(72.2cm/2*3.14) = R

11.5cm = R

Then the volume is approx:

The functions g(x) = x² - 4x + 3 and f(x) = x² - 4x are:

The functions have the same range.

The functions have the same domain.

The functions have the same x-intercepts.

Let's analyze the given functions g(x) = x² - 4x + 3 and f(x) = x² - 4x and determine which statements about them are true.

Here are the options:

The functions have the same graph.

The functions have the same range.

The functions have the same domain.

The functions have the same vertex.

The functions have the same y-intercept.

The functions have the same x-intercepts.

The functions have the same graph:

This statement is false. While both functions are quadratic functions, their additional terms make them different. g(x) has an additional constant term (+3) compared to f(x).

Their graphs will be different, with g(x) being shifted upward by 3 units compared to f(x).

The functions have the same range:

This statement is true.

Both functions are quadratic functions, and their range will be the same. The range of a quadratic function is either all real numbers (if the parabola opens upward) or the set of real numbers greater than or equal to (or less than or equal to) the vertex of the parabola.

The functions have the same domain:

This statement is true.

The domain of both functions, unless restricted by any other factors, is all real numbers.

Quadratic functions have a domain of (-∞, ∞).

The functions have the same vertex:

This statement is false.

The vertex of a quadratic function is determined by the values of "a," "b," and "c" in the general form of the quadratic function (ax^2 + bx + c).

Since g(x) has an additional constant term, its vertex will be different from the vertex of f(x).

The functions have the same y-intercept:

This statement is false.

The y-intercept of a function is the value of y when x = 0.

For f(x), when x = 0, we have f(0) = (0)² - 4(0) = 0.

For g(x), when x = 0, we have g(0) = (0)² - 4(0) + 3

= 3.

Their y-intercepts are different.

The functions have the same x-intercepts:

This statement is true.

To find the x-intercepts of both functions, we set y (or f(x) and g(x)) equal to zero and solve for x.

The quadratic equation x² - 4x + 3 = 0 can be factored as (x - 1)(x - 3) = 0, giving x = 1 and x = 3 as the x-intercepts.

Both functions have the same x-intercepts.

63 is the sum of 15 and Gail's score:

The inventory turnover ratio can be calculated by dividing the cost of goods sold by the average inventory value. In this case, the inventory turnover ratio is 0.5, and the correct answer is (D) 0.5.

The inventory turnover ratio measures the number of times a company sells and replaces its inventory during a period. It can be calculated by dividing the cost of goods sold by the average inventory value.

The inventory turnover ratio = Cost of goods sold / Average inventory value

In this case, the cost of goods sold is $600,000 and the average inventory value is $1,200,000.

Inventory turnover ratio = $600,000 / $1,200,000 = 0.5

Therefore, the inventory turnover ratio is 0.5, and the correct answer is (D) 0.5.

Step-by-step explanation:

f(x) = sin^-1(4x)

Using the chain rule, we have:

f'(x) = (1/√(1 - (4x)^2)) * d/dx(4x)

= (1/√(1 - (4x)^2)) * 4

= 4/√(1 - (4x)^2)

y = tan^-1(√(x-2))

Using the chain rule, we have:

y' = (1/ (1 + (√(x-2))^2)) * (1/2)(x-2)^(-1/2)

= 1 / (2√(x-2)(1 + x - 2))

= 1 / (2√(x-2)(x - 1))

y = (tan^−1(5x))^2

Using the chain rule and power rule, we have:

y' = 2(tan^−1(5x)) * d/dx(tan^−1(5x))

= 2(tan^−1(5x)) * (1/(1 + (5x)^2)) * 5

= 10(tan^−1(5x))/(1 + (5x)^2)

h(x) = e^(x^8+ln(x))

Using the chain rule and product rule, we have:

h'(x) = e^(x^8+ln(x)) * d/dx(x^8+ln(x))

= e^(x^8+ln(x)) * (8x^7 + 1/x)

= x^(15)e^(x^8) + e^(x^8)/x

y = ln(e^−x + xe^−x)

Using the chain rule and sum rule, we have:

y' = (1/(e^−x + xe^−x)) * d/dx(e^−x + xe^−x)

= (1/(e^−x + xe^−x)) * (-e^−x + e^−x - xe^−x)

= -1/(e^−x + xe^−x)

y = (cos(9x))^x

Using the chain rule and power rule, we have:

y' = (cos(9x))^x * d/dx(x * ln(cos(9x)))

= (cos(9x))^x * (ln(cos(9x)) + x * (-sin(9x)) * (1/cos(9x)) * 9)

= (cos(9x))^x * (ln(cos(9x)) - 9x * tan(9x))

Answer:

The range of the given function has one restriction, its denominator can't be zero, hence:

Therefore the function can get any value but zero:

The matching answer choice is D.

Linear function is f(x) = mx + b.

Reciprocal of a function f(x)  is 1/f(x).

So the reciprocal of linear function has a form of f(x) = 1 / (mx + b).

The only answer choice in same form is D.

Substitute x = - 5/3 into function to get:

This is undefined value, therefore it represents the vertical asymptote.

The function gets close to - ∞ when x → - 5/3 from left and gets close to +∞ when x → - 5/3 from right (see attached graph).

Therefore the correct choice is B.

9¹⁰ can be expressed as base 4 with 22 and 15¹⁰ can be expressed as 33.

An expression is combination of variables, numbers and operators.

To change from base 10 to base 4, we need to express each number in terms of powers of 4. Here's how you can do this for each number:

9¹⁰ in base 4:

9 in base 10 can be expressed as 22

Base 4

So, (22)¹⁰ = 4¹⁰ x 2¹⁰ = 1048576 x 1024

= 1073741824 in base 10.

15¹⁰ in base 4

15 in base 10 can be expressed as 33 in base 4

Frr and thanks

Step-by-step explanation:

Based on the Inscribed Angle Theorem, the measure of angle 1 is calculated as: m<1 = 130°.

The Inscribed Angle Theorem states that an angle inscribed in a circle is half the measure of the central angle that intercepts the same arc and also half of the intercepted arc measure itself.

In other words, if we draw a circle and a chord inside the circle, and then draw an angle with its vertex on the circle and its rays intersecting the chord and the circle, then the measure of this angle is half the measure of the central angle that has the same endpoints on the circle as the inscribed angle and intercepts the same arc.

Applying this theorem, we have:

measure of angle 1 = 1/2 * (260°)

measure of angle 1 = 260/2

Measure of <1 = 130°

The triangle congruence criteria that can be used to prove that DEF and D'EF are congruent is the SAS rule.

It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.

We have,

The SAS rule states that "If two sides and the included angle of one triangle are equal to corresponding two sides and included angle of another triangle, then the triangles are congruent"

From ΔDEF and ΔD'EF

DE = D'E

m∠DEF = m∠D'EF

EF = EF

ΔDEF ≈ ΔD'EF
