The interval that function f(x)=x³-9x has a positive average rate of change is [ -4, -1 ].

Option D) is the correct answer.

To determine whether the average rate of change is positive, f(max) - f(min) must be greater than zero.

Given the function; f(x) = x³ - 9x

We determine f(max) - f(min)

At interval [ -2, 1 ]

(x³ - 9x) - ( x³ - 9x )

( (1)³ - 9(1) ) - ((-2)³ - 9(-2))= -8 - 10 = -18 NOT POSITIVE

At interval [ -2, 3 ]

(x³ - 9x) - ( x³ - 9x )

( (3)³ - 9(3) ) - ((-3)³ - 9(-3))= 0 - 0 = 0 NOT POSITIVE

At interval [ -1, 2 ]

(x³ - 9x) - ( x³ - 9x )

( (2)³ - 9(2) ) - ((-1)³ - 9(-1))= -10 - 8 = -18 NOT POSITIVE

At interval [ -4, -1 ]

(x³ - 9x) - ( x³ - 9x )

( (-1)³ - 9(-1) ) - ((-4)³ - 9(-4))= 8 - (-28) = 36 POSITIVE

Therefore, the interval that function f(x)=x³-9x has a positive average rate of change is [ -4, -1 ].

Option D) is the correct answer.

The equation of line that passes through a pair of points: (2, 3), (4, -2).is option B. y = -5/2 x + 8.

Suppose the given points are (x_1, y_1) and (x_2, y_2),

then the equation of the straight line joining both two points is given by

[tex](y - y_1) = \dfrac{y_2 - y_1}{x_2 - x_1} (x -x_1)[/tex]

We need to find the equation of the line that passes through a pair of points: (2, 3), (4, -2).

So, the equation would be

[tex](y - y_1) = \dfrac{y_2 - y_1}{x_2 - x_1} (x -x_1)[/tex]

Step-by-step explanation:

The height of a triangle with a hypotenuse of 23 and angle between base and hypotenuse of 75° is h= 23sin(75)

An equation is an expression that shows the relationship between two or more variables and numbers.

Trigonometric ratio shows the relationship between the sides and angles of a right angle triangle.

Let us assume that the right triangle has a altitude h, hypotenuse of 23 and angle between base and hypotenuse is 75°, hence:

sin(75) = h/23

h= 23sin(75)

Thus we can conclude that if Will is 34% higher than Wanda, then Will's height is 134% (100% + 34%) of Wanda's height.

Will is 34% taller than Wanda, so Will's height is 134% of Wanda's height.

If Will is 34% of Wanda's height, we can conclude that he has all of Wanda's height plus 34% of that height.

All the height of Wanda represents 100% as it is referring to a complete system.

Height is a way to measure someone or something from base to top or head to toe.

From this, we can conclude that Will is 100% more than 34% of Wanda's height.

Thus we can conclude that if Will is 34% higher than Wanda, then Will's height is 134% (100% + 34%) of Wanda's height.

Answer:

[tex]57[/tex]

Step-by-step explanation:

You just plug in 8 as a, and 7 as b. This gives you the following equation: [tex](8)^2-7[/tex] which becomes [tex]64-7[/tex] by squaring the 8, Then subtract 7 and you get [tex]57[/tex]

Answer:

57

Step-by-step explanation:

a = 8

b = 7

a² - b

= 8² - 7

= (8*8) - 7

= 64 - 7

= 57

The amount loaned at 8% is  $4800.

The amount loaned at 18% is $6,200.

a + b - 11,000 equation 1

0.08a + 0.18b = 1500 equation 2

Where:

a = amount loaned at 8%

b = amount loaned at 18%

Multiply equation 1 by 0.08

0.08a + 0.08b = 880 equation 3

Subtract equation 3 from equation 2

0.10b = 620

b = 620 / .10

b = $6200

a = 11,000 - 6200 = $4800

Answer:

[tex]y = -\frac{x}{6} + \frac{14}{3}[/tex]

Step-by-step explanation:

So when you're solving for y you want to get y by it self meaning there should be nothing with y, including any coefficients. The first step is to usually move any terms to the other side and then divide by the coefficient of y so y "technically doesn't" have a coefficient, while it does, but that coefficient 1, so it doesn't really mean much.

Subtract x from both sides

[tex]6y = -x+28[/tex]

Divide both sides by 6

[tex]y = -\frac{x}{6} + \frac{14}{3}[/tex]

The given equation solved for y as y = (28 - x)/6.

The given equation is x+6y=28.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

The given equation can be solved for y as follows

Here, x+6y=28

⇒ 6y = 28 - x

⇒ y = (28 - x)/6

Therefore, the given equation solved for y as y = (28 - x)/6.

We can simplify the given rational function into a linear one, the graph is below.

Here we have the rational function:

[tex]f(x) = \frac{4x^2 - 16}{2x - 4}[/tex]

Factorization the numerator, we get:

4x² - 16 = 0

4x² = 16

x² = 16/4 = 4

x = ±√4 = ±2

Then the numerator can be written as:

4*(x - 2)*(x + 2)

And the denominator can be rewritten as:

2x - 4 = 2*(x - 2)

Then the function becomes:

[tex]f(x) = \frac{4*(x + 2)*(x - 2)}{2*(x - 2)} \\\\f(x) = 2*(x + 2) = 2x + 4[/tex]

This is an academic integrity violation because it is against honesty rules, the best would be to offer assistance to your friend.

Academic integrity encompasses principles of honesty, fairness, and trustworthiness in academic pursuits. It generally includes a commitment to originality and independent work. Assisting someone in completing an exam, especially a take-home exam, where individual effort and understanding are expected, would likely violate academic integrity policies.

Handling the situation ethically and responsibly would involve respecting the academic rules and ensuring fairness for all students. Instead of directly completing the exam for your friend, you can offer assistance by explaining concepts, providing guidance on problem-solving approaches, or reviewing their completed work to identify errors or areas for improvement. This way, you can help your friend learn the material and develop their own understanding, without compromising academic integrity.
