Step-by-step explanation:

The given equation is;

[tex]x^3-9x^2+23x-15=0[/tex]

To solve by the x-intercept method we need to graph the corresponding function using a graphing tool.

The corresponding function is

[tex]f(x)=x^3-9x^2+23x-15[/tex]

The solution to [tex]f(x)=x^3-9x^2+23x-15=0[/tex] is where the graph touches the x-axis.

We can see from the graph  that; the x-intercepts are;

(1,0),(3,0) and (5,0).

Therefore the real solutions are:

Answer:

Step-by-step explanation:

Parallelogram's diagonals theorem states that the diagonals in a parallelogram must bisect each other.

So for ABCD to be a parallelogram, the two diagonals must be divided in equal sections.

That is given for BD already.

For AC, 3x = 4x - 6

Rearranging, 4x - 3x = 6

x = 6

Answer:

B.

Step-by-step explanation:

Because the graph shown is not constant, if you look at when it hits a whole unit. It is increasing because it is moving right.

The true statement is:

B.  

The function indicates that the number of members is increasing at a rate that is not constant.

We could write the data points as is given on the graph as follows:

  x       y

  0      40

  1       50

  2      60

  3      80

  4      100

  5      120

  6      150

  7      190

  8      240

  9      300

  10     370

Hence, the rate of change from x=0 to x=1 is:

[tex]Rate=\dfrac{50-40}{1-0}\\\\\\Rate=\dfrac{10}{1}\\\\\\Rate=10[/tex]

Rate of change from x=3 to x=5 is:

[tex]Rate=\dfrac{120-80}{5-3}\\\\\\Rate=\dfrac{40}{2}\\\\\\Rate=20[/tex]

Hence, the rate is not constant.

Also we could see that with the increasing value of x the y-value also increases.

                  Hence, option: B is the correct answer.

Answer:

D) 8

Step-by-step explanation:

Given function for height =  f(x) = 80(0.5)^x

It shows that the height of ball after any bounce can be calculated by putting bounce number in place of x in this equation.

so, height after first bounce f(1) is calculated by placing 1 in place of x

f(1) = 80(0.5)^1

f(1) = 80(0.5)

f(1) = 40

Similarly, the height after 4th bounce f(4)

f(4) = 80(0.5)^4

f(4) = 80(0.0625)

f(4) = 5  

Therefore, the height of 1st bounce is 40/5 = 8 times higher than the fourth bounce. So, option D is correct.

The first bounce is 8 times higher than the fourth bounce. Option D (8) is correct.

The height of the bouncing ball is given by the function f(x) = 80(0.5)^x, where x represents the number of bounces. To find how many times higher the first bounce is than the fourth bounce, we'll calculate the heights for f(1) and f(4) and then compare them.

Therefore, the first bounce is 8 times higher than the fourth bounce, corresponding to option D (8).

Answer:

0.731 < p < 0.775

Step-by-step explanation:

We have a sample proportion of 753/1000 = 0.753

We need to construct a 90% confidence interval for the population proportion.  Since n > 30, we use the corresponding z-value of 1.645.  

See attached photo for the formulas and construction of the confidence interval.

The 90% confidence interval for the proportion of American adults who think exercise is an important part of daily life is 0.749 to 0.757.

To find the 90% confidence interval for the proportion of American adults who think exercise is an important part of daily life, we can use the formula for the confidence interval of a proportion. The formula is: CI = p ± Z * sqrt((p * (1-p))/n), where p is the sample proportion, Z is the z-score corresponding to the desired confidence level, and n is the sample size.

First, we need to calculate the sample proportion: p = 753/1000 = 0.753.

Next, we need to find the z-score for a 90% confidence level. Looking up the z-score in the standard normal distribution table, we find that the z-score for a 90% confidence level is approximately 1.645.

Now we can plug in the values into the formula: CI = 0.753 ± 1.645 * sqrt((0.753 * (1-0.753))/1000).

Calculating the expression inside the square root gives us approximately 0.0027. Plugging this value into the formula gives us the 90% confidence interval for the proportion: CI = 0.753 ± 1.645 * 0.0027.

Calculating this expression gives us the lower and upper bounds of the confidence interval: CI = 0.753 ± 0.0044.

To determine how many kilometers east Santos walked, we can use the Pythagorean theorem to find the distance traveled for each leg of the journey.

To determine how many kilometers east Santos walked, we need to use the Pythagorean theorem to find the distance traveled for each leg of the journey. Since he ends up 5 kilometers away from his starting position, we can form a right triangle with the hypotenuse representing the total distance walked.

Let's assume Santos walked x kilometers east. The other leg of the triangle represents the 2 kilometers south he walked. Using the Pythagorean theorem, we have x2 + 22 = 52.

This simplifies to x2 + 4 = 25. Subtracting 4 from both sides gives us x2 = 21. Taking the square root of both sides, we find that x ≈ 4.58. Therefore, Santos walked approximately 4.58 kilometers east.

Answer:

43.75 ft²

Step-by-step explanation:

     Let r = the radius of the semicircle

   and h = the height of the rectangle

Then 2r = the width of the window

The formula for the perimeter of a circle is C = 2πr,

so, πr = the perimeter of the semicircle

The perimeter of the window is

P = πr + 2h + 2r = 25

      2h + (π +2)r = 25

                       h = ½[25 - (π + 2)r]

(1)                   h = 12.5 - (π/2 +1)r

The formula for the area of a circle is A= πr²,  so

½πr² = the perimeter of the semicircle

The area of the window is

(2) A = ½πr² + 2rh

Substitute (1) into (2).

    A = ½πr² + 2r[12.5 - (π/2 +1)r] = ½πr² + 25r - (π +2)r²

    A = 25r - (π + 2 - π/2)r²

(3) A =  -(π/2 + 2)r² + 25r

This is the equation for a downward opening parabola.

One way to find the vertex is to set the first derivative equal to zero.

dA/dr = -2(π/2 + 2)r + 25 = 0

               -(π    + 4)r  + 25 = 0

               -(π     + 4)r        = -25

                                     r = 25/(π + 4)

(4)                                 r ≈ 3.50 ft

The maximum area occurs when r = 3.50 ft.  

Substitute (4) into (1).

h = 12.5 - (π/2 +1)(3.50) = 12.5 - (2.571× 3.50) = 12.5 - 9.00 = 3.50  

(4) h = 3.50 ft

Substitute (4) into (2)

A =  1.571(3.50)² + 2×3.50×3.50 = 19.25 + 24.50

A = 43.75 ft²

The area of the largest possible Norman window with a perimeter of 25 ft is 43.75 ft².

The maximum area of a Norman window with a given perimeter of 25 feet can be found by creating an equation for the area, taking its derivative, setting it equal to zero and solving for the window's dimensions. This involves calculus, namely the method for optimization problems.

The problem involves maximizing the area of a Norman window given a certain perimeter. The Norman window is composed of a rectangle and a semicircle, where the diameter of the semicircle equals the width of the rectangle. First, let's denote the width of the rectangle or the diameter of the semicircle as x. The radius of the semicircle will then be x/2. The height of the rectangle can be represented as 25 - x (since the perimeter of the window should equal 25 feet).

The area of a rectangle is height multiplied by width. The area of a semicircle is (1/2)πr2. So to find the area A of the Norman window, we add the area of the rectangle and the semicircle: A = x(25-x) + (1/2)π*(x/2)2.

To find the maximum area, we need to take the derivative of A with respect to x, set it equal to zero, and solve for x. We find x approximates to around 7.64 feet (after using calculus concepts). Then substitute x = 7.64 into the area function A and solve for A, which gives us the maximum area of the Norman window.

6) x² + y² + 2x - 6y - 9 = 0 ⇒ (x + 1)² + (y - 6)² = 46

Step-by-step explanation:

- The general form of the equation of the circle is:

* x² + y² + Dx + Ey + F = 0

 where D , E and F are constant

- The standard form of the equation of the circle is:

* (x - h)² + (y - k)² = r²

 where (h , k) is the center of the circle, r is the radius of it

- To chose the circle equations in general form with their

  corresponding equations in standard form lets do that

1) x² + y² - 4x + 12y - 20 = 0

- we will start to find h and k

∵ h = -coefficient x ÷ 2 coefficient x²

∴ h = -(-4)/2(1) = 2

∵ k = -coefficient y ÷ 2 coefficient y²

∴ k = -(12)/2(1) = -6

∵ r² = h² + k² - F

- where F is the numerical term of the general form

∴ r² = (2)² + (-6)² - (-20) = 4 + 36 + 20 = 60

∴ The equation of the circle in standard form is:

* (x - h)² + (y + k)² = r²

∴ (x - 2)² + (y + 6)² = 60 ⇒ x² + y² - 4x + 12y - 20 = 0

2) x² + y² + 6x - 8y - 10 = 0

- we will start to find h and k

∵ h = -coefficient x ÷ 2 coefficient x²

∴ h = -(6)/2(1) = -3

∵ k = -coefficient y ÷ 2 coefficient y²

∴ k = -(-8)/2(1) = 4

∵ r² = h² + k² - F

- where F is the numerical term of the general form

∴ r² = (-3)² + (4)² - (-10) = 9 + 16 + 10 = 35

∴ The equation of the circle in standard form is:

* (x - h)² + (y + k)² = r²

∴ (x + 3)² + (y - 4)² = 35 ⇒ there is no choice

3) 3x² + 3y² + 12x + 18y - 15 = 0

- we will start to find h and k

∵ h = -coefficient x ÷ 2 coefficient x²

∴ h = -(12)/2(3) = -2

∵ k = -coefficient y ÷ 2 coefficient y²

∴ k = -(18)/2(3) = -3

∵ r² = h² + k² - F

- where F is the numerical term of the general form

∴ r² = (-2)² + (-3)² - (-15/3) = 4 + 9 + 5 = 18

- We divide F by 3 because the coefficient of x² and y²

∴ The equation of the circle in standard form is:

* (x - h)² + (y + k)² = r²

∴ (x + 2)² + (y + 3)² = 18 ⇒ 3x² + 3y² + 12x + 18y - 15 = 0

4) 5x² + 5y² - 10x + 20y - 30 = 0

- we will start to find h and k

∵ h = -coefficient x ÷ 2 coefficient x²

∴ h = -(-10)/2(5) = 1

∵ k = -coefficient y ÷ 2 coefficient y²

∴ k = -(20)/2(5) = -2

∵ r² = h² + k² - F

- where F is the numerical term of the general form

∴ r² = (1)² + (-2)² - (-30/5) = 1 + 4 + 6 = 11

- We divide F by 5 because the coefficient of x² and y²

∴ The equation of the circle in standard form is:

* (x - h)² + (y + k)² = r²

∴ (x - 1)² + (y + 2)² = 11 ⇒ there is no choice

5) 2x² + 2y² - 24x - 16y - 8 = 0

- we will start to find h and k

∵ h = -coefficient x ÷ 2 coefficient x²

∴ h = -(-24)/2(2) = 6

∵ k = -coefficient y ÷ 2 coefficient y²

∴ k = -(-16)/2(2) = 4

# x² + y² + 2x - 12y - 9 = 0 ⇒ (x + 1)² + (y - 6)² = 46

Step-by-step explanation:

* Lets study the problem to solve it

- Use the terms of x and y in the general form to find the standard form

∵ x² + y² - 4x + 12y - 20 = 0

- Use the term x term

∵ -4x ÷ 2 = -2x ⇒ x × -2

∴ (x - 2)²

- Use the term y term

∵ 12y ÷ 2 = 6y ⇒ y × 6

∴ (y + 6)²

∵ (-2)² + (6)² + 20 = 4 + 36 + 20 = 60

∴ x² + y² - 4x + 12y - 20 = 0 ⇒ (x - 2)² + (y + 6)² = 60

∵ x² + y² + 6x - 8y + 10 = 0

- Use the term x term

∵ 6x ÷ 2 = 3x ⇒ x × 3

∴ (x + 3)²

- Use the term y term

∵ -8y ÷ 2 = -4y ⇒ y × -4

∴ (y - 4)²

∵ (3)² + (-4)² - 10 = 9 + 16 - 10 = 5

∴ x² + y² + 6x - 8y + 10 = 0 ⇒ (x + 3)² + (y - 4)² = 5 ⇒ not in answer

∵ 3x² + 3y² + 12x + 18y - 15 = 0 ⇒ divide all terms by 3

∴ x² + y² + 4x + 6y - 5 = 0

- Use the term x term

∵ 4x ÷ 2 = 2x ⇒ x × 2

∴ (x + 2)²

- Use the term y term

∵ 6y ÷ 2 = 3y ⇒ y × 3

∴ (y + 3)²

∵ (2)² + (3)² + 5 = 4 + 9 + 5 = 18

∴ 3x² + 3y² + 12x + 18y - 15 = 0 ⇒ (x + 2)² + (y + 3)² = 18

∵ 5x² + 5y² - 10x + 20y - 30 = 0 ⇒ divide both sides by 5

∴ x² + y² - 2x + 4y - 6 = 0

- Use the term x term

∵ -2x ÷ 2 = -x ⇒ x × -1

∴ (x - 1)²

- Use the term y term

∵ 4y ÷ 2 = 2y ⇒ y × 2

∴ (y + 2)²

∵ (-1)² + (2)² + 6 = 1 + 4 + 6 = 11

∴ 5x² + 5y² - 10x + 20y - 30 = 0 ⇒ (x - 1)² + (y + 2)² = 11 ⇒ not in answer

∵ 2x² + 2y² - 24x - 16y - 8 = 0 ⇒ divide both sides by 2

∴ x² + y² - 12x - 8y - 4 = 0

- Use the term x term

∵ -12x ÷ 2 = -6x ⇒ x × -6

∴ (x - 6)²

- Use the term y term

∵ -8y ÷ 2 = -4y ⇒ y × -4

∴ (y - 4)²

∵ (-6)² + (-4)² + 4 = 36 + 16 + 4 = 56

∴ 2x² + 2y² - 24x - 16y - 8 = 0 ⇒ (x - 6)² + (y - 4)² = 56

∵ x² + y² + 2x - 12y - 9 = 0

- Use the term x term

∵ 2x ÷ 2 = x ⇒ x × 1

∴ (x + 1)²

- Use the term y term

∵ -12y ÷ 2 = -6y ⇒ y × -6

∴ (y - 6)²

∵ (1)² + (-6)² + 9 = 1 + 36 + 9 = 46

∴ x² + y² + 2x - 12y - 9 = 0 ⇒ (x + 1)² + (y - 6)² = 46

So the ratio are 1:2:3:4 and all these add up to 10

Now we divide 360 by 10 resulting to 36

A=(36)

B=(72)

C=(108)

D=(144)

All these add up to 360 and has been divided equally according to the ration provided

Final answer:

To find the measures of the angles in quadrilateral ABCD with ratios 1:2:3:4, we set the angles as x, 2x, 3x, and 4x, and use the fact that their sum equals 360 degrees. Solving for x, we find x to be 36 degrees, which gives us the individual angles as 36 degrees, 72 degrees, 108 degrees, and 144 degrees respectively.

Explanation:

Calculating the Measures of the Angles in a Quadrilateral

Given that the measures of the angles A, B, C, and D in quadrilateral ABCD are in the ratio of 1:2:3:4 respectively, we first need to understand that the sum of the interior angles in a quadrilateral is always 360 degrees. To find the measure of each angle, we should express the ratio in terms of x, which would give us the angles as x, 2x, 3x, and 4x. Summing these and setting them equal to 360 degrees, we get the equation x + 2x + 3x + 4x = 360. Simplifying, we have 10x = 360, which when solved for x yields x = 36 degrees. Therefore, the measures of the angles are:

Angle A = 1x = 36 degrees

Angle B = 2x = 72 degrees

Angle C = 3x = 108 degrees

Angle D = 4x = 144 degrees

Hence, each angle's measure has been found using the given ratio and the property of the sum of interior angles in a quadrilateral.

Answer:

B) 1.

Step-by-step explanation:

x^2 - 8x + 7 = 0

(x - 1)(x - 7) = 0

x= 1, 7.

Answer:

x = 1

Step-by-step explanation:

Please express exponentiation using the symbol  " ^ "  :  x^2 - 8x + 7 = 0

Let's solve this equations using "completing the square:"

x^2 - 8x + 7 = 0

1) Identify the coefficient of the x term.  Here it's -8.

2) take half of that and square it:  we get (-4)² = 16

3) insert " +16 - 16 " between the 8x and the 7:

        x^2 - 8x +  16 - 16  +7 = 0

4)  Rewrite this perfect square:

          (x - 4)² - 16 + 7 = 0  ->   (x - 4)^2 = 9

5)  Solve for (x -4) by taking the square root of both sides:

           x - 4 ± sqrt(9)    ->  x - 4 ± 3

6)  Solve for x:  x = 4  ± 3, or x = 7 and x = 1.  

7)  Take the lesser root of 7 and 1.  That would be x = 1.  Answer B is correct.

Answer:

See below

Step-by-step explanation:

The score increase was 35 points. They claimed an increase of at least 50 points.  For a significance level of 5%, the z-score for the situation needs to be at smaller than -1.645.  For a significance level of 1%, the z-score needs to be smaller than -2.325

The z score for our situation:  z = (385 - 350)/50 = 0.7

The average score of 385 of Tutor O-Rama scores is not significantly different from the average of the other students SAT scores.  The evidence doesn't support their claim of being effective tutoring.

The number [tex] \pi [/tex] is defined as the ratio between the circumference and the diameter of a circle. In other words, for every circle, we have

[tex]\pi=\dfrac{C}{d}=\dfrac{C}{2r}[/tex]

Since the diameter is twice the radius.

Solving for the circumference, we have

[tex]C=2\pi r[/tex]

So, in your case, the answer is

[tex]C=16\pi[/tex]

Answer:

50.24

Step-by-step explanation:

2 time legal assistant = 900,000 x 2 = 1,800,000

school teacher = 1,850,000

Difference = 1,850,000 - 1,800,000 = $50,000

Master degree for 26 weeks = 1326 x 26 = 34,476

Associates degree for 42 weeks: 792 x 42 = 33,264

Difference = 34,476 - 33,264 = $1,212

For 20 years she earned: $900,000

Twice that would be $1,800,000

So for 30 years the schoolteacher earns the same amount.

Answer:

The difference between the school teacher and the legal assistant is $50,000. The school teacher earns about twice as much in thirty years. The next answer is $1,212.  

Step-by-step explanation:

The legal assistant makes $1,800,000 in 40 year. The school teacher in 30 years makes 1,850,000. 1,850,000 - 1,800,000= $50,000.

A person with the masters degree mages $34,476 in 26 weeks.The person with the Associates degree make $33,264 in 42 weeks.

Answer:

38°

Step-by-step explanation:

The triangle solver app on your calculator, phone, or tablet can solve this for you readily. There are on-line triangle solvers, too.

___

For solution "by hand", the Law of Cosines is useful. It tells you ...

a^2 = b^2 + c^2 -2ab·cos(A)

Then the angle A can be found as ...

cos(A) = (b^2 +c^2 -a^2)/(2ab) = (3^2 +7^2 -5^2)/(2·3·7) = 33/42 = 11/14

A = arccos(11/14) ≈ 38°

_____

In formulas like the Law of Cosines or the Law of Sines, the uppercase letters stand for the measures of angles, and the lowercase letters stand for their opposite side lengths.

Answer:

[tex]log_{3}(x . y^\frac{1}{3} / z^5 )[/tex]

Step-by-step explanation:

Given in the question an expression

[tex]log_{3} x+\frac{1}{3}log_{3} y-5log_{3} z[/tex]

To Condense this log into a single log we will use logarithm rules

logb(x^y) = y ∙ logb(x)

[tex]\frac{1}3}log_{3} y = log_{3}y^\frac{1}{3}[/tex]

[tex]5log_{3} z = log_{3} z^5[/tex]

logb(x ∙ y) = logb(x) + logb(y)

[tex]log_{3} x + log_{3}y^\frac{1}{3} = log_{3}(x . y^\frac{1}{3} )[/tex]

[tex]logb(x / y) = logb(x) - logb(y)\\log_{3}(x . y^\frac{1}{3} )- log_{3} z^5[/tex]

= [tex]log_{3}(x . y^\frac{1}{3} / z^5 )[/tex]
