One root of f(x)=x^3-9x^2+26x-24 is x = 2. What are all the roots of the function?

Answers

The roots of the function is 26

Answer:

Solutions are

[tex]x_{1}=4\\x_{2}=2\\ x_{3}=3[/tex]

Step-by-step explanation:

The given expression is

[tex]f(x)=x^{3}-9x^{2} +26x-24[/tex]

First, we need the divisors of the independent term, which is 24.

24 divisors: 1, 2, 3, 4, 6, 8, 12, 24.

Now, we replace each divisor in the function, and those which gives zero as result, those are gonna be the roots of the equation.

For [tex]x=1[/tex]

[tex]f(1)=(1)^{3}-9(1)^{2} +26(1)-24=1-9+26-24=-6[/tex]

This means [tex]x=1[/tex] is not a solution.

For [tex]x=2[/tex]

[tex]f(2)=(2)^{3}-9(2)^{2} +26(2)-24=8-36+52-24=0[/tex]

So, [tex]x=2[/tex] is the first solution.

For [tex]x=3[/tex]

[tex]f(3)=(3)^{3}-9(3)^{2} +26(3)-24=27-81+78-24=0[/tex]

It's solution.

For [tex]x=4[/tex]

[tex]f(4)=(4)^{3}-9(4)^{2} +26(4)-24=64-144+104-24=0[/tex]

Therefore, all roots are

[tex]x_{1}=4\\x_{2}=2\\ x_{3}=3[/tex]

Suppose your club is selling candles to raise money. It cost $100 to rent a booth from which to sell the candles. If the candles cost your club $1 and are sold for $5 each, how many candles must be sold to equal your expenses?

Answers

let x = # candles sold

100 + x = 5x
4x = 100
x = 25

answer
25 candles must be sold to equal expenses

25 candles

What is profit and loss ?

Profit or Gain = Selling price – Cost Price

Loss = Cost Price – Selling Price

According to the given question,

Candles sold must cover the expenses = 100

Let x be the no. of candles that needs to be sold to cover the expenses

rent = 100

Cost price of 1 candle = CP = 1

Cost price of x candles = CP = 1x

Selling price of 1 candle = SP = 5

Selling price of x candles = SP = 5x

Therefore, from the above statements we can infer that the profit generated must be equal to the expenses,

So, SP - CP = Profit = 100

5x - x = 100

4x = 100

x = 25

Therefore, we need 25 candles that needs to be sold to cover the expenses

A high fountain of water is in the center of a circular pool of water. you walk the circumference of the pool and measure it to be 190 meters. you then stand at the edge of the pool and use a protractor to gauge the angle of elevation of the top of the fountain. it is 55°. how high is the fountain?

Answers

The first thing we must take into account is that the circumference of the pool is given by:
2 * pi * R = 190
From here, we clear the radio:
R = (190) / (2 * pi)
R = 30.23943919 m
Then, you can see the problem as a rectangle triangle, where the height of the source will be given by the following trigonometric relationship:
tan (55) = H / R
From here, we clear the height H:
H = R * tan (55)
H = (30.23943919) * tan (55)
H = 43,1863948 m
Amswer:
the fountain is 43.19 m high

The height of the fountain is 43.20m

Data;

circumference = 190mangle = 55 degrees.

Circumference of a Circle

How much Will be left after
45 hours if an isotope has a half life of 15 hours and you have 371 MGS

Answers

[tex]\bf \textit{Amount for Exponential Decay using Half-Life}\\\\ A=P\left( \frac{1}{2} \right)^{\frac{t}{h}}\qquad \begin{cases} A=\textit{accumulated amount}\\ P=\textit{initial amount}\to &371\\ t=\textit{elapsed time}\to &45\\ h=\textit{half-life}\to &15 \end{cases} \\\\\\ A=371\left( \frac{1}{2} \right)^{\frac{45}{15}}\implies A=371\left( \frac{1}{2} \right)^3[/tex]

and surely you know how much that is.

After 45 hours, approximately 46.375 mg of the isotope will be left, given its half-life is 15 hours. This was determined by calculating the amount remaining after each of three half-lives. Each half-life reduces the amount by half.

To determine how much of the isotope is left after 45 hours, we need to use the concept of half-life. The half-life of the isotope is 15 hours. This means that every 15 hours, half of the isotope decays. We start with 371 mg.

First, calculate how many half-lives have passed:

45 hours / 15 hours per half-life = 3 half-lives

After each half-life, the amount of isotope remaining is halved:

After the first half-life (15 hours): 371 mg / 2 = 185.5 mgAfter the second half-life (30 hours): 185.5 mg / 2 = 92.75 mgAfter the third half-life (45 hours): 92.75 mg / 2 = 46.375 mg

Therefore, after 45 hours, approximately 46.375 mg of the isotope will be left.

The number of diagonals in any polygon is whole number. But on the other side the formula of the number of diagonals in any convex polygon is in a fraction form \frac{n(n-3)}{2[tex] . How can you explain this?

Answers

you can explain this by doing n-3 times 2

I think the formula for the number of diagonals of a convex polygon is actually
[tex]N=n(n-1)/2[/tex]
This will always give a result of a whole number because
if n is odd, then n-1 is even, or
if n is even, n-1 must be odd.
So the division by 2 will always give a whole number because there is always an even number in the numerator.

By the way, this number is also solution to the "hand-shake" problem, which is "how many possible handshakes in a group of n people, if everyone shakes hand with everyone else exactly once?" Therefore, again, it is a whole number.

Your friend scores a 22.5 on a normally distributed new logic test with a mean of 20 and a standard deviation of 2.5, and you're confident that 13.59% of people are more logical than your friend but not as logical as you. if you're really as smart as you think you are, what would you score on the test?

Answers

The z-score for the point x = 22.5 is: z = (x - m) / s = (22.5 - 20) / 2.5 = 1. The probability that z > 1, determined from z-tables, is p (z > 1) = 0.1587. If 13.59% of people score higher than the friend, but not higher than you, this means that only 0.1587 - 0.1359 = 0.0228 of people scored higher than you. Checking the z-table for the z-score for which p (z > z_cutoff) = 0.0228, z_cutoff = 2. Therefore this z_cutoff of 2 corresponds to x = m + zs = 20 + 2(2.5) = 25, which would be your score on the test.

To find the actual distance you will convert the 2 feet to inches because the scale is given in miles to inches.

2 feet = 24 inches

128 miles/6 inches is the scale.

Solve this equation: 3x-1/5-2/9x=124/5
Step 1: Simplify by combining like terms. Which terms can be combined?
A) 3x and -1/5
B) -1/5 and -2/9x
C) 3x and -2/9x

Answers

Answer:

The correct option is C.

Step-by-step explanation:

The given equation is

[tex]3x-\frac{1}{5}-\frac{2}{9}x=\frac{124}{5}[/tex]

If two terms have the same variables having same powers, then they are known as like terms.

In the given equation [tex]3x[/tex] and [tex]-\frac{2}{9}x[/tex] are like terms.

So, when we simplify the given equation by combining like terms. we need to combined [tex]3x[/tex] and [tex]-\frac{2}{9}x[/tex] .

Therefore the correct option is C.

The solution to the equation is approximately x = 45.48.

To solve the equation 3x - 1/5 - 2/9x = 124/5, to combine like terms. Like terms are terms that have the same variable and exponent.

The terms in the equation are:

3x (coefficient is 3, and the variable is x)

-1/5 (coefficient is -1/5)

-2/9x (coefficient is -2/9, and the variable is x)

Now, let's identify the like terms that combined:

C) 3x and -2/9x

The terms 3x and -2/9x both have the variable x, so they are like terms and can be combined.

Step 1: Combine the like terms:

3x - 2/9x = (3 - 2/9)x = (27/9 - 2/9)x = (25/9)x

Now, after combining the like terms, the equation becomes:

(25/9)x - 1/5 = 124/5

Step 2: Isolate x on one side of the equation. To do this, we can first get rid of the fraction by multiplying the entire equation by the least common multiple (LCM) of the denominators, which is 45 (LCM of 9 and 5):

45 × [(25/9)x - 1/5] = 45 × (124/5)

This simplifies to:

25x - 9 = 1128

Step 3: Now, isolate x by moving the constant term (-9) to the other side of the equation:

25x = 1128 + 9

25x = 1137

Step 4: Finally, divide by 25 to solve for x:

x = 1137 / 25

x ≈ 45.48

b. How many minutes did it take to run 1 kilometer?

Answers

Answer:

it take 31.53 minutes to run the entire race

it take 6.3 minutes to run the 1 km

Step-by-step explanation:

A runner ran 2/3 of a 5 kilometer race in 21 minutes. They ran the entire race at a constant speed.

[tex]\frac{2}{3} \cdot 5= \frac{10}{3}[/tex]

3.33 km is covered in 21 minutes

So 5 km is covered in [tex]\frac{5 \cdot 21}{3.33}=31.53[/tex]minutes

it take 31.53 minutes to run the entire race

[tex] \frac{10}{3}[/tex] km is covered in 21 minutes

1 km is covered in [tex]\frac{21}{\frac{10}{3} } =6.3[/tex]

It takes to run the entire race is 31 minutes and 30 seconds and it takes to run 1 kilometer is 6 minutes and 18 seconds.

What is speed?

The distance covered by the particle or the body in an hour is called speed. It is a scalar quantity. It is the ratio of distance to time.

We know that the speed formula

[tex]\rm speed = \dfrac{distance}{time}[/tex]

A runner ran 2/3 of a 5 kilometers race in 21 minutes. They ran the entire race at a constant speed.

2/3 of 5 km is given as x

[tex]x = \dfrac{2}{3}* 5 = \dfrac{10}{3}[/tex]

Then the speed will be

[tex]\rm speed = \dfrac{\frac{10}{3}}{21} = \dfrac{10}{3*21} = \dfrac{10}{63}[/tex]

a. It takes to run the entire race will be

[tex]\rm Time = \dfrac{5}{ \frac{10}{63}} = \dfrac{63* 5 }{10} =31.5[/tex]

It takes to run the entire race is 31 minutes and 30 seconds.

B. It takes to run 1 kilometer will be

[tex]\rm Time = \dfrac{1}{ \frac{10}{63}} = \dfrac{63* 1}{10} = 6.3[/tex]

It takes to run 1 kilometer is 6 minutes and 18 seconds.
