Answer:

The factored form of given polynomial is [tex]x^3(4x^2-5x-9)[/tex]

Step-by-step explanation:

Given the polynomial [tex]4x^5 - 20x^4 - 36x^3[/tex]

We have to factor the above polynomial completely.

[tex]4x^5 - 20x^4 - 36x^3[/tex]

Take [tex]x^3[/tex] common from each term.

[tex]x^3(4x^2-5x-9)[/tex]

Here, the quadratic polynomial is prime i.e it cannot be factored into lower degree polynomial. It has complex roots.

Hence, the factored form of given polynomial is [tex]x^3(4x^2-5x-9)[/tex]

Answer: 4x^3(x^2 - 5x - 9)

Proof of validity is shown below.

Answer:

Correct option is:

C. [tex](x-\sqrt{3})(x^2+3+x\sqrt{3} )[/tex]

Step-by-step explanation:

x^3-3sqrt(3)

=  [tex]x^3-3\sqrt{3} \\\\=x^3-\sqrt{3}^3[/tex]

= [tex](x-\sqrt{3})(x^2+3+x\sqrt{3} )[/tex]

(since, [tex]a^3-b^3=(a-b)(a^2+b^2+ab)[/tex])

Hence, the correct option is:

   C.    [tex](x-\sqrt{3})(x^2+3+x\sqrt{3} )[/tex]

The probability that the commuter doesn't get stopped all week long is approximately 0.44.

To find the probability that the commuter doesn't get stopped all week long, we need to find the probability of not getting stopped on each day and then multiply those probabilities together. Since the commuter estimates that he gets stopped on about 15% of work days, the probability of not getting stopped on a single day is 1 - 15% = 85%. To find the probability of not getting stopped all week, we raise 85% to the power of 5, since there are 5 work days in a week:

Probability of not getting stopped all week = (85%)5 = 0.85 * 0.85 * 0.85 * 0.85 * 0.85 = 0.44370515625.

The probability that the commuter doesn't get stopped by the train all week long is 44%.

This question falls under the category of probability in mathematics. The commuter estimates he'll get stopped 15% of work days, which implies that he'll have a smooth commute 85% of the time (100% - 15%). In a 5-day work week, the probability that he doesn't get stopped at all can be computed by multiplying the probability of not getting stopped each day. Therefore, the answer is (0.85)^5 or approximately 0.44, which represents 44%.

the right answer is 44.

Answer:

44 degrees.

Step-by-step explanation:

We are asked to find the measure of angle Q using law of cosines.

Law of cosines:

[tex]c^2=a^2+b^2-2ab\times cos(C)[/tex]

Upon substituting our given values in above formula we will get,

[tex]24^2=20^2+34^2-2\times 20\times 34\times cos(Q)[/tex]

[tex]576=400+1156-1360\times cos(Q)[/tex]

[tex]576=1556-1360\times cos(Q)[/tex]

[tex]576-1556=1556-1556-1360\times cos(Q)[/tex]

[tex]-980=-1360\times cos(Q[/tex]

Upon dividing both sides of our equation by -1360 we will get,

[tex]\frac{-980}{-1360}=\frac{-1360\times cos(Q}{-1360}[/tex]

[tex]0.7205882352941176=cos(Q)[/tex]

Now we will use arccos to solve for the measure of angle Q.

[tex]cos^{-1}(0.7205882352941176)=Q[/tex]

[tex]43.896932391182=Q[/tex]

[tex]Q\approx 44[/tex]

Therefore, the measure of angle Q is 44 degrees.

The total travel time one way is 288 minutes.

To find the total travel time one way, we need to add up the time spent on each part of the journey. The salesman spends 1 hour and 48 minutes commuting from his house to the airport. Let's convert this to minutes, which gives us 60 + 48 = 108 minutes.

Next, we add the flight time. The question doesn't specify the duration of the flight, so we can't determine that. We'll assume it takes 2 hours, which is 120 minutes. Finally, we add the time spent on the bus. Again, the question doesn't provide this information, so let's assume it takes 1 hour (60 minutes) by bus.

Adding up the commute time, flight time, and bus time, we get 108 + 120 + 60 = 288 minutes. Therefore, the total travel time one way is 288 minutes.

Answer:

78,000

Step-by-step explanation:

9.75 is 7.8 times larger than 1.25.

However, we have powers of 10.  In the first number, 10 is raised to the 6th power; in the second number, 10 is raised to the 2nd power.  This means that the first number is 10⁴ times bigger than the second one, or 10000 times bigger.

This means in total, the first number is 7.8(10000) = 78000 times larger than the second one.

This can be confirmed by dividing the two; 9.75(10⁶)÷1.25(10²) = 78000

Answer:

The correct answer is twelve.

Step-by-step explanation:

The values of a would make the expression 36, 49 and 81.

The correct options are b, c, and d.

For variable x : ax² + bx + c = 0, where a≠0 is a standard quadratic equation, which is a second-order polynomial equation in a single variable. It has at least one solution since it is a second-order polynomial equation, which is guaranteed by the algebraic basic theorem.

To factor the expression x² - a completely, we need to write it as a product of two binomials.

This can be done using the difference of squares formula, which states that a² - b² = (a + b)(a - b).

If we apply this formula to x² - a, we get:

x² - a = (x + sqrt(a))(x - sqrt(a))

This is a factorization of x² - a into two binomials, where the constant term a is represented by the square root of a.

For the expression x² - a to be completely factored, both factors must be irreducible (meaning they cannot be factored any further). This requires that a be a perfect square.

Out of the given options, 36, 49, and 81 are perfect squares.

$2500 is invested at an interest rate of 4.5% per year, compounded daily for 2 years will amount to $5225.

Borrowers are required to pay interest on interest in addition to principal since compound interest accrues and is added to the accrued interest from prior periods.

We know the formula for compound interest is,

A = P(1 + r/100)ⁿ.

Where, A = amount, P = principle, r = rate, and n = time in years.

Given,  $2500 is invested at an interest rate of 4.5% per year, compounded daily, and assuming it is for 2 years.

∴ The amount compounded daily will be,

A = P(1 + (r/365)/100)ⁿˣ³⁶⁵ as compounded daily.

A = 2500(1 + (4.5/365)/100)²ˣ³⁶⁵.

A = 2500( 1 + 0.00101)⁷³⁰.

A = 2500(1.00101)⁷³⁰.

To calculate the future value of an investment of $2500 at a 4.5% interest rate compounded daily for 5 years, we use the compound interest formula. Assuming 5 years of growth, the future value would be approximately $3117.14.

If $2500 is invested at an interest rate of 4.5% per year, compounded daily, we need to find the value of the investment after a certain number of years. The formula to calculate the future value of an investment with daily compounding is given by:

FV = P × (1 + r/n)^(n×t)

where:

To calculate the future value, we plug in the values into the formula. However, the number of years, t, has not been specified, so we'll need that to give a final answer. For our purposes, let's assume the student asks for the value after 5 years. Using the formula:

FV = $2500 × (1 + 0.045/365)^(365×t)

FV = $2500 × (1 + 0.00012328767)^(1825)

FV = $2500 × 1.246856823

FV = $3117.14 (rounded to the nearest cent)

After 5 years, the investment would be worth approximately $3117.14.

Final answer:

The total duration of the appointment was 2 hours and 45 minutes.

Explanation:

To determine how long the appointment lasted, we need to calculate the time difference between the start time and the end time. The appointment started at 2:30 pm and ended at 5:15 pm.

First, take note of the start time: 2:30 pm.

Then, take note of the end time: 5:15 pm.

Calculate the hours by subtracting the start hour from the end hour: 5 pm - 2 pm = 3 hours.

Next, calculate the minutes by subtracting the start minutes from the end minutes: 15 minutes - 30 minutes. Since you cannot have a negative number of minutes, you need to borrow an hour from the 3 hours calculated, making it 2 hours, and add 60 minutes to the 15 minutes. Now, 75 minutes - 30 minutes = 45 minutes.

Combine the total hours and minutes: 2 hours and 45 minutes
