Which Of The Following Statement(s) Describes The Rate Of Change Of F Over The Interval 1.5 X 3? Select

Answers

Answer 1

Answer:

B. The rate of change is 2.

C. The rate of change is constant.

D. The rate of change is increasing.

Step-by-step explanation:

Rate of change over 1.5 ≤ x ≤ 3:

[tex] rate of change = \frac{f(b) - f(a)}{b - a} [/tex]

Where,

a = 1.5, f(a) = 1,

b = 3, f(b) = 4

Plug in the values:

[tex] rate of change = \frac{4 - 1}{3 - 1.5} = \frac{3}{1.5} = 2 [/tex]

✔️The rate of change = 2

✔️The rate of change is increasing because the value is a positive value.

✔️The rate of change is also constant over 1.5 ≤ x ≤ 3 since the line is straight.

Answer 2

The points on the interval of the absolute value function in the graph are on the same straight line.

The statements that describe the rate of change over the interval; 1.5 ≤ x ≤ 3 are;

B. The rate of change is 2C. The rate of change is constant

Reasons:

The given parameter of the graph of the f are;

The vertex of the function = (1, 0)

The straight line of the function f passes through the points (1.5, 1) and (3, 4)

Therefore;

[tex]\displaystyle The \ slope \ of \ the \ graph \ between \ (1.5, \, 1) \ and \ (3, \, 4) = \mathbf{\frac{4 - 1}{3 - 1.5} }= \frac{3}{1.5} =2[/tex]

The slope of the graph = The rate of change of the graph

Therefore;

The rate of change of the graph over the interval 1.5 ≤ x ≤ 3 is 2

The rate of change is 2

Given that the graph is a straight line graph, we have;

The slope of the graph is constant, therefore;

The rate of change is constant

joan needs $60 for a class trip. She has $32. She can earn $4 an hour mowing lawns. How many hours must Joan to have the money she needs?​

Answers

She already has 32$. And makes 4$ every hour of mowing lawns.

4 + 4 + 4 + 4 + 4 + 4 + 4 = 30 = 4 x 7 which equals 30



Joan needs to work 7 hours in total to get 28$.

Joan has 32$. And makes 4$ every hour of mowing lawns.

60-32=28.

So what we will do to solve this problem is multiply 7 by 4.

7x4= 28.

32+28=60.

Find the values of x and y . Then find the measures of the interior angles of the polygon.

Answers

Step-by-step explanation:

It is a cyclic quadrilateral.

The sum of interior angles of this polygon is equal to 180 degrees.

ATQ,

2x+26y=180

x+13y=90 ....(1)

3x+21y=180

x+7y=60 ....(2)

Subtract equation (1) from (2).

x+7y-(x+13y) = 60-90

x+7y-x-13y=-30

-6y=-30

y = 5

Put the value of y in equation (1

x+13(5) = 90

x+65=90

x = 90-65

x = 25

So,

∠DAB = 26y = 26(5) = 130°

∠ABC = 3x = 3(25) = 75°

∠BCD = 2x = 2(25) = 50°

∠ADC = 21y = 21(5) = 105°

    x = 25, y = 5

    m∠DAB = 26(y) = 180°

    m∠ABC = 3x = 75°

    m∠BCD = 2x = 50°

    m∠ADC = 21y = 105°

Property of a cyclic quadrilateral:   Sum of the opposite angles of a cyclic quadrilateral is 180°.

From the picture attached,

  ABCD is a cyclic quadrilateral.   m∠A = 26y°, m∠B = 3x°, m∠C = 2x° and m∠D = 21y°

By using the property of cyclic quadrilateral,

m∠A + m∠C = 180°

26y + 2x = 180

13y + x = 90 --------(1)

m∠B + m∠D = 180°

3x + 21y = 180

x + 7y = 60 --------(2)

Subtract equation (2) from (1),

(13y + x) - (x + 7y) = 90 - 60

6y = 30

y = 5

Substitute y = 5 in equation (1),

13(5) + x = 90

x = 90 - 65

x = 25

Substitute the values of 'x' and 'y' to get the measures of the angles,

m∠DAB = 26(y) = 180°

m∠ABC = 3x = 75°

m∠BCD = 2x = 50°

m∠ADC = 21y = 105°

         Therefore, values of the variables will be,

                            x = 25, y = 5

                            m∠DAB = 26(y) = 180°

                            m∠ABC = 3x = 75°

                            m∠BCD = 2x = 50°

                            m∠ADC = 21y = 105°

Find all x-intercepts of the following function. Write your answer or answers as coordinate points. Be sure to select the appropriate number of x-intercepts.

Answers

Answer:

(- 3, 0 ), (4, 0 )

Step-by-step explanation:

To find the x- intercepts let f(x) = 0

[tex]\frac{x^2-x-12}{5x^2+ 4x}[/tex] = 0

The denominator cannot equal zero as this would make f(x) undefined.

Equate the numerator to zero and solve for x

x² - x - 12 = 0 ← in standard form

(x - 4)(x + 3) = 0 ← in factored form

Equate each factor to zero and solve for x

x - 4 = 0 ⇒ x = 4

x + 3 = 0 ⇒ x = - 3

x- intercepts are (- 3, 0 ) and (4, 0 )

3 more than 2 times a number is equal to that number plus 4. What is the number?

Answers

Answer:

number is 1

Step-by-step explanation:

let the number be n , then 2 times the number is 2n and 3 more than this is

2n + 3 , so

2n + 3 = n + 4 ( subtract n from both sides )

n + 3 = 4 ( subtract 3 from both sides )

n = 1

That is the number is 1

The required number is 1 which represents "3 more than 2 times a number is equal to that number plus 4"

What is the number system?

A number system is defined as a way to represent numbers on the number line using a set of symbols and approaches. These symbols, which are known as digits, are numbered 0 through 9.

Let the required number would be x.

According to the given question, translate the phrase into an algebraic equation:

3 + 2x = x + 4

Subtracting x from both sides gives:

3 + 2x - x = x + 4 - x

Simplifying the left side gives:

3 + x = 4

Subtracting 3 from both sides gives:

3 + x - 3 = 4 - 3

Simplifying the left side gives:

x = 1

Therefore, the required number would be 1.
