Answer:

P = 50.39 cm

Step-by-step explanation:

It is given that,

The side of a square, a = 5∛16 cm

We need to find the perimeter of the square.

Perimeter = sum of all sides.

All sides of a square are equal. Its perimeter is given by :

P = 4a

\(P=4\times 5\sqrt[3]{16} \\\\P=50.39\ cm\)

So, the exact perimeter of the square is 50.39 cm.

Answer:

The student didn't fully factorize out the terms to the least factor. He only collected some like terms but there was still more to collect and that's why the Teacher didn't give him full credit

Step-by-step explanation:

The original polynomial is;

4x²y^(5) - 8xy³

Now, if we want to completely factor this properly, we have to do it to the barest minimum.

Thus;

4xy³ is common to both terms so we can bring them out;

4xy³(xy² - 2)

Now this complete factorization is different from the one the student gave which is 2xy³(2xy³ - 4)

Thus, the student at best has factorized but only partly as it has not been reduced to the least of like terms.

By the given condition we find that to calculate the cost of the notebooks and newspaper is impossible, from the given condition we get only no solutions.

Let the cost of the notebooks and newspaper in Liam's bookstore be x and y respectively.

According to the given question.

Liam's bookstore sold total 40notesbooks and 20 newspater for $130.

⇒ 40x + 20y = 130

⇒ 20(2x + y) = 130

⇒ 2x + y = 6.5 ...(i)

And the next day,

The bookstore sold 8 notebooks and 4 newspapers for $130.

⇒ 8x + 4y = 28

⇒ 4(2x + y ) = 28

⇒ 2x + y = 7 ...(ii)

Since, if we see the  two equations i and ii we find that the given conditions provide no solutions.

Answer:

12.78 units

Step-by-step explanation:

The formula for arc length =

2πr × θ/360

From the question:

θ = 122°

r = 6 units

Therefore, the arc length =

2 × π × 6 × (122/360)

= 12.775810125 units

Approximately to the nearest hundredth = 12.78 units

Therefore, the length of arc CE is 12.78 units

If a random variable "z" follows a standard normal distribution and the probability of "z" being greater than "k" is 0.39, then the value of "k" such that satisfies the equation [p(z > k) = 0.39] will be 0.28

As per the question statement, a random variable "z" follows a standard normal distribution.

We are required to determine the value of "k" such that the equation   [p(z > k) = 0.39] is satisfied.

To solve this question, first we will have to calculate the probability of "z" being greater than "k" and then from the Z-table, we will determine the z-score corresponding the above calculated probability value. This z-score will be our desired answer, i.e.,

Given, P(Z > k)  = 0.39

Or, P(Z < k) = (1 - 0.39)

Or, P(Z < k) = 0.61

Now, from the Z table, we get the z-score corresponding to probability value of 0.61 is 0.28

Hence, (k = 0.28)

Given that Ruby has saved $4072.24, and she initially invested $2500, we can plug in these values into the formula:

4072.24 = 2500(1 + r/1\()^{(1 )(10)\)

Simplifying the equation, we get:

(1 + r)¹⁰ = 4072.24/2500

Taking the 10th root of both sides, we have:

1 + r = (4072.24/2500\()^{(1/10)\)

Subtracting 1 from both sides, we find:

r = (4072.24/2500\()^{(1/10)\)- 1

r = 1.05000008852 - 1

r = 0.05000008852

The total US dollars it cost to Tom to get the rupees he wants for the trip of India is $270 round to the nearest dollar.

Percentage of a number is the part of the number expressed in the in every hundred. Percentage of a number is expressed with the symbol '%'.

To calculate the percentage part of number, multiply it with the original number and divide with 100.

Tom is exchanging money for his trip to india. The exchange rate of us dollars to indian rupees is,

\(r=\dfrac{1}{45.897}\)

Tom needs 11,550 rupees. The dollars need for 11550 Indian rupees are,

\(n=\dfrac{11550}{45.897}\\n=251.65\)

The currency exchange service he is using charges a fee of 7.25% after the exchange is made. Thus the total dollar requied after the service charge is,

\(n=251.65+\dfrac{7.25}{100}\times251.65\\n=251.65+18.245\\n=269.895\\n\approx270\)

An expression representing how many strawberries will be needed in x desserts: 4x The variable "x" represents the number of desserts Heather will make.

In part B, we are given the ounces of strawberries Heather will be using. With the expression above, we can make an equation out of it. 4x = 24 With "x" of desserts, Heather is making, all we have to do is solve for the value of "x" to find the no. of desserts she will make with 24 ounces of strawberries. Divide both sides by 4. x = 6 She can make 6 desserts with 24 ounces of strawberries.

Using the multiplication and addition operations, if Fabian leaves a 15% tip, his meal plus the tip, before tax, is $40.25.

Multiplication and addition operations are two of the four basic mathematical operations.

Multiplication involves the use of multiplicand, multiplier, multiplication operand, equal symbol, and product.

The addition operation involves using the two addends, the equal sign, and the sum.

Dinner cost before tip and tax = $35

Tip = 15%

Total cost before tax = 115% (100 + 15)

Dinner cost after tip = $40.25 ($35 x 1.15)

Thus, mathematically, Fabian will spend $40.25 for the dinner before tax.

Step-by-step explanation:

Given that we have the graph of f(x), we want to see which one is the graph of its inverse. i just had that question and i got a 100 on it

The Absolute minimum and maximum values of the function are:

Absolute minimum value = (0.1, 0.2)

Absolute maximum value = (1, 2)

We have,

The function f(x) = 2x is continuous and differentiable for all values of x in the interval [0.1, 1].

To find the absolute maximum and minimum values of f(x) on this interval, we need to find the critical points of the function, which are the points where the derivative of the function is zero or undefined, and the endpoints of the interval.

The derivative of f(x) is f'(x) = 2, which is a constant function that is always defined and never zero.

Therefore, there are no critical points in the interval [0.1, 1].

The endpoint values of the interval are f(0.1) = 0.2 and f(1) = 2.

Therefore, the absolute minimum value of f(x) on the interval [0.1, 1] is f(0.1) = 0.2, which occurs at x = 0.1,

The absolute maximum value of f(x) on the interval [0.1, 1] is f(1) = 2, which occurs at x = 1.

So, the location and value of the absolute extreme values of the function f(x) on the interval [0.1, 1] are:

Absolute minimum value: (0.1, 0.2)

Absolute maximum value: (1, 2)

Thus,

Absolute minimum value: (0.1, 0.2)

Absolute maximum value: (1, 2)

The present value of the deferred annuity at January 1, 2014, is approximately $133,012.89.

To calculate the present value of a deferred annuity, we need to consider the average length of time to retirement, the expected life duration after retirement, the annual pension payment, and the interest rate. Let's break down the steps involved in calculating the present value.

The average length of time to retirement is given as 15 years. Since the pension plan starts on January 1, 2014, we can assume that all employees will retire 15 years from that date, which would be January 1, 2029.

Therefore, the total number of pension payments would be 17 - 1 = 16.

To calculate the present value factor, we use the formula:

=> Present Value Factor = 1 / (1 + interest rate)ⁿ,

where n is the total number of pension payments.

Using the formula, the present value factor would be

=> 1 / (1 + 0.07)¹⁶ = 0.37908.

To calculate the present value of the deferred annuity, we multiply the total pension payment expected each year after retirement by the present value factor. In this case, the total pension payment is $351,150 per year.

Present Value of the Annuity = Total Pension Payment * Present Value Factor

= $351,150 * 0.37908

= $133,012.89 (rounded to two decimal places)
