According to the real rational root theorem, what are all the potential rational roots of f(x)=5x3-7x+11

Answers

Answer 1

Answer:

x = -11, -11/5, -1, -1/5, 1/5, 1, 11/5,11

Step-by-step explanation:

The general formula for a third-degree polynomial is

f(x) = ax³ + bx² + cx + d

Your polynomial is  

f(x) = 5x³ + 7x + 11

a = 5; d = 11

p/q = Factors of d/Factors of a

Factors of d = ±1, ±11

Factors of a = ±1, ±5

Potential roots are x = ±1/1, ±1/5, ±11/1, ±11/5

Putting them in order, we get the potential roots

x = -11, -11/5, -1, -1/5, 1/5, 1, 11/5, 11

(There are no rational roots. There is one irrational root and two imaginary roots.)

Eva makes and sells her own cranberry apple fruit punch for the holidays.
In jug A, she mixes 4 cranberry flavored cubes and 3 apple flavored cubes with some water.
In jug B, she mixes 3 cranberry flavored cubes and 2 apple flavored cubes with some water.
If you ask her for a drink that has a stronger cranberry taste, from which jug should Eva pour you drink?

Answers

Eva should pour you a drink from jug B for a stronger cranberry taste, as it has a higher ratio of cranberry to apple cubes compared to jug A, demonstrating the use of ratios in mathematics.

To decide which jug of fruit punch has a stronger cranberry taste, we should look at the ratio of cranberry flavored cubes to apple flavored cubes in both jugs. For jug A, the ratio is 4 cranberry cubes to 3 apple cubes, which simplifies to approximately 1.33 cranberry cubes for every apple cube. For jug B, the ratio is 3 cranberry cubes to 2 apple cubes, which simplifies to 1.5 cranberry cubes for every apple cube.

Since jug B has a higher ratio of cranberry to apple, it has a stronger cranberry taste compared to jug A. So, Eva should pour you a drink from jug B if you want a drink with a stronger cranberry flavor. This involves a practical application of ratios and proportions, which are key concepts in mathematics used to compare quantities.

Jasper used 15 inches of blue ribbon,14 of yellow ribbon,and 3 feet of red ribbon to decorate his box of cookies.How many inches of ribbon did jasper use?

Answers

Answer:65 inches


Step-by-step explanation:

15+14+36=65

Final answer:

Jasper used a total of 65 inches of ribbon.

Explanation:

To calculate the total length of ribbon used by Jasper, we need to convert the 3 feet of red ribbon to inches.

Since 1 foot is equal to 12 inches, 3 feet would be equal to 12 x 3 = 36 inches. Then, we can add up the lengths of all three ribbons: 15 inches of blue ribbon + 14 inches of yellow ribbon + 36 inches of red ribbon = 65 inches of ribbon.

What are mathematical operations?

The term "operation" in mathematics refers to the process of computing a value utilizing operands and a math operator. For the specified operands or integers, the math operator's symbol has predetermined rules that must be followed. In mathematics, there are five basic operations: addition, subtraction, multiplication, division, and modular forms.

Given an expression:

(a²-4ac+3bc)/(a²-ab+bc-ac) + (a+3b)/(b-a) + (a+2c)/(a-c)

Simplifying Using PEMDAS starts from the right:

(a²-4ac+3bc)/(a²-ab+bc-ac) + [tex]\frac{a^{2} + 3ab - ac - 3bc }{-a^{2} + ab -bc +ac }[/tex]

Taking negative common from the last term

(a²-4ac+3bc)/(a²-ab+bc-ac) - (a² + 3ab - ac -3bc)/(a²-ab+bc-ac)

Since the base is the same,

(-4ac + 3bc - 3ab +ac +3bc)/(a²-ab+bc-ac)

3(bc - ac - ab)/(a²-ab+bc-ac)

therefore, the simplified form of the given equation is 3(bc - ac - ab)/(a²-ab+bc-ac).

what equation describes a line passing through (-6,-5) that is perpendicular to a line described by y=-2/3x?

Answers

Final answer:

The equation of the line passing through (-6,-5) and perpendicular to y=-2/3x is y=(3/2)x+4.

Explanation:

To find an equation of a line passing through the point (-6,-5) that is perpendicular to the line described by y=-2/3x, we first need to determine the slope of the perpendicular line. Since perpendicular lines have slopes that are negative reciprocals of each other, the slope of our line will be the negative reciprocal of -2/3, which is 3/2.

Now, using the point-slope form of the equation of a line, which is y - y1 = m(x - x1), where m is the slope and (x1, y1) is a point on the line, we can substitute our point (-6, -5) and slope 3/2 into the formula:

y - (-5) = (3/2)(x - (-6))

Simplifying this, we get:

y + 5 = (3/2)(x + 6)

y + 5 = (3/2)x + 9

Subtracting 5 from both sides, we get the final equation of the line:

y = (3/2)x + 4

In triangle FGH, FH=10 units and GH=26 units. Which is the length of FG?

Answers

Final answer:

To find the length of FG in triangle FGH, we can use the Pythagorean Theorem. By substituting the given values into the formula and solving for FG, we find that FG is approximately 27.9 units.

Explanation:

To find the length of FG, we can use the Pythagorean Theorem, which states that the square of the hypotenuse of a right triangle is equal to the sum of the squares of the other two sides.

In this case, FH and GH are the two sides of the right triangle FGH, and FG is the hypotenuse. So we have FH² + GH²= FG².

Substituting the given values, we have 10² + 26² = FG². Simplifying this equation, we get 100 + 676 = FG². Adding the numbers gives us 776 = FG². And taking the square root on both sides, we find that FG ≈ 27.9 units.

Write down any irrational number between 4 and 6 please explain how do you get the answer

Any irrational number never ends. So, you can take square roots. 4 is the square root of 16, and 6 is the square root of 36. So, take the square root of any number between 16 and 36 except for 25. For example, 17 is between 16 and 36. So, sqrt(17) is therefore irrational. You can't take the square root of 25 because that would result in a rational number, 5.


Round answer to the nearest tenth. . An accident investigator measured the skid marks of one of the vehicles involved in an accident. The length of the skid marks was 175 feet. What was the speed of the vehicle before the brakes were applied?

Answers

Answer:

v2 - v02 = 2ad

 

v = final speed = 0 (came to a full stop)

v0 = initial speed (what you want to solve for)

d = stopping distance = 175 feet

 

Then

 

v0 = √(-2ad)  [Remember a is negative, so the argument of the square root is positive.]

 

But as you can see, we need the acceleration.

 

If we knew the time it took to come to a full stop, we could still answer the question.  Either way, we need more information than just the stopping distance.

Step-by-step explanation:


The speed of the vehicle before the brake were applied was about 83.7 feet/s

Further explanation

Acceleration is rate of change of velocity.

[tex]\large {\boxed {v^2 = u^2 + 2ad}[/tex]

[tex]\large {\boxed {a = \frac{v - u}{t} } }[/tex]

[tex]\large {\boxed {d = \frac{v + u}{2}~t } }[/tex]

a = acceleration ( m/s² )

v = final velocity ( m/s )

u = initial velocity ( m/s )

t = time taken ( s )

d = distance ( m )

Let us now tackle the problem!

This problem is about accelerated motion.

Given:

final speed of the vehicle = v = 0 feet/s

length of skid marks = d = 175 feet

maximum deceleration = a = 20 feet/s² ( assumption )

Unknown:

initial speed = u = ?

Solution:

[tex]v^2 = u^2 - 2ad[/tex]

[tex]0^2 = u^2 - 2(20)(175)[/tex]

[tex]u^2 = 7000[/tex]

[tex]u = \sqrt{7000}[/tex]

[tex]u = 10\sqrt{70} \texttt{ feet/s}[/tex]

[tex]u \approx 83.7 \texttt{ feet/s} [/tex] (rounded to the nearest tenth)

[tex]\texttt{ }[/tex]

Conclusion:

The speed of the vehicle before the brake were applied was about 83.7 feet/s if we assume that maximum deceleration of the vehicle is about 20 feet/s²

Larry uses his credit card to purchase a new video game system for $445.07 he can pay off off up to $200 per month the card has an annual rate of 13.6% compounded monthly how much total interest will he pay

Answers

Larry will pay a total interest of $45.07 when using his credit card to purchase the video game system.

To calculate the total interest Larry will pay when using his credit card to purchase a video game system for $445.07, with a monthly payment limit of $200 and an annual rate of 13.6% compounded monthly, we can follow these steps:

1. Calculate the total amount to be paid off by subtracting the monthly payment from the total purchase amount:

Total amount to be paid off = $445.07 - $200 = $245.07

2. Determine the number of months it will take to pay off the balance by dividing the total amount to be paid off by the monthly payment:

Number of months = $245.07 / $200 = approximately 1.22535 months (round up to the nearest whole month, which is 2 months)

3. Calculate the monthly interest rate by dividing the annual rate by 12 (since it's compounded monthly):

Monthly interest rate = 13.6% / 12 = 1.1333%

4. Use the formula for compound interest to find the total interest paid:

Total interest = Total amount paid - Total principal amount

Total principal amount = $445.07

Total amount paid = $200 * 2 = $400

Total interest = $400 - $445.07 = $45.07

Therefore, Larry will pay a total interest of $45.07 when using his credit card to purchase the video game system.

A. Ordered pairs can be written as relation

-4→-4;2→0;6→4;10→2.

Here each input value of x determines one output value of y and this set of ordered pairs represents function.

B. Ordered pairs can be written as relation

9→3;9→-3;4→2;5→-2.

Here for input value x=9 there are 2 output values of y (y=3 or y=-3). This set of ordered pairs doesn't represent function.

C. Ordered pairs can be written as relation

-3→7;-2→7;1→7;0→7.

There is exactly one y for each x, then this set of ordered pairs represents function.

8.4 = 6 + 0.08x

8.4 - 6 = 0.08x

[tex]x = \frac{8.4- 6}{0.08}[/tex]

[tex]x = \frac{2.4}{0.08}[/tex]

[tex]x = \frac{24\times 100}{8\times 10}[/tex]
