Gracie has two identical fidget cubes shown below. The edge length of the fidget cubes is 4 centimeters. What is the combined volume of the two fidget cubes in cubic centimeters?​

Where the above is given, NPV is $0.5bn and  rNPV is $0.305bn. Thus, the patent is financially feasible and shows positive returns, considering both risk and cost.

To evaluate the financial viability   of the patent, we can calculate its net present value (NPV) by comparing  the expected cash flows with the initial cost.

Given that the expected present value of the   cash flows is $3.5 billion and the cost is $3 billion,we can calculate the NPV as follows -

NPV = Expected Present Value - Cost

    = $3.5 billion - $3 billion

    = $0.5 billion

Since the NPV is positive, the patent appears to be financially feasible.

To consider the   risk associated with the patent's cash flows, we can calculate the standard deviation of the expected   cash flows.

Given that the standard deviation is 30%,this indicates a level of variability or uncertainty in the cash flow projections.

To assess   the risk-adjusted profitability of the patent, we can calculate the risk-adjusted NPV (rNPV) by discounting the expected cash flows using therisk-free rate.

Given that the risk-free rate is 4.5%, we can calculate the rNPV as follows -

rNPV = Expected Present Value - Cost / (1 + Risk-Free Rate)^Life of the Patent

      = $3.5 billion -   $3billion / (1 + 0.045)²⁰

      ≈ $0.305 billion

The positive rNPV suggests that the patent is still financially feasible after considering the risk associated with the cash flows.

The correct statement regarding Python indentation is that incorrect indentation will result in an "IndentationError."

The correct output for the given "for" loop and "range" function is:

99 88 77 66 55 44 33 22 11 0 -11

Regarding the statement about a "Fatal" logic error in Python, the correct answer is:

In script mode - Python displays a traceback, then terminates the script.

When a fatal logic error occurs in Python during script execution, Python will display a traceback message that provides information about the error, such as the line where it occurred, and then terminates the script. This traceback message helps in debugging the code and identifying the cause of the error.

In interactive mode, if a fatal logic error occurs, Python will also display a traceback message but will not terminate the entire session. Instead, it will allow you to continue entering new commands or snippets of code.

Regarding Python indentation, the correct statement is:

Incorrect indentation will result in an "IndentationError."

Python relies on indentation to define the grouping and structure of code blocks. It uses consistent indentation to determine which lines of code belong to a particular block, such as loops or conditional statements. If the indentation is incorrect or inconsistent, Python will raise an "IndentationError" and the code will not run successfully.

Step one:

mass of Freight car=25tons

the rate of filling is 1/3 ton per minute

let the time taken to fill the freight car be x

and the total mass after x minute be y

Hence the mass as a function of time is expressed as

y=25+1/3x----------1

mas of dump truck=55tons

rate of being emptied= 1/6 tons per minute

let the time taken to empty the dump truck be x

In order to calculate the time it will take for Andrew to settle the loan, we can use the formula for compound interest. So, it will take Andrew approximately 5.22 years to settle the loan.

The formula is given as A = P(1 + r/n)^(nt), Where: A = the final amount, P = the principal (initial amount borrowed), R = the annual interest rate, N = the number of times the interest is compounded in a year, T = the time in years.

We know that Andrew borrowed R200 000 from a bank at an annual interest rate of 5.25% compounded quarterly and that he will make repayments of R6 000 at the end of every 3 months.

Since the first repayment will be made 3 months from now, we can consider that the initial loan repayment is made at time t = 0. This means that we need to calculate the value of t when the total amount repaid is equal to the initial amount borrowed.

Using the formula for compound interest: A = P(1 + r/n)^(nt), We can calculate the quarterly interest rate:r = (5.25/100)/4 = 0.013125We also know that the quarterly repayment amount is R6 000, so the amount borrowed minus the first repayment is the present value of the loan: P = R200 000 - R6 000 = R194 000

We can now substitute these values into the formula and solve for t: R194 000(1 + 0.013125/4)^(4t) = R200 000(1 + 0.013125/4)^(4t-1) + R6 000(1 + 0.013125/4)^(4t-2) + R6 000(1 + 0.013125/4)^(4t-3) + R6 000(1 + 0.013125/4)^(4t)

Rearranging the terms gives us: R194 000(1 + 0.013125/4)^(4t) - R6 000(1 + 0.013125/4)^(4t-1) - R6 000(1 + 0.013125/4)^(4t-2) - R6 000(1 + 0.013125/4)^(4t-3) - R200 000(1 + 0.013125/4)^(4t) = 0

Using trial and error, we can solve this equation to find that t = 5.22 years (rounded to 2 decimal places). Therefore, it will take Andrew approximately 5.22 years to settle the loan.

Let's assume the sum of the scores of the 28 students who took the test yesterday is 28 * 72 = 2016.

We know that the sum of the scores of all 30 students is (28 * 72) + x + y, where x and y are the scores of the two students who took the test this morning.

We also know that the mean of all 30 scores is 73. So we can write an equation:

[(28 * 72) + x + y]/30 = 73

Multiplying both sides by 30, we get:

2016 + x + y = 2190

So, x + y = 174.

We are given that the difference of the two scores is 22, so we can write another equation:

y - x = 22

Solving these two equations simultaneously, we get y = 98 and x = 76.

Therefore, the lower score from this morning is 76.

Therefore, the maximum displacement of the particle is 4 units, and it occurs at time t = 1.

To find the maximum displacement, we need to first determine the particle's velocity and acceleration.

The velocity of the particle is given by the derivative of its position function:

\(v(t) = y'(t) = 3t^2 - 12t + 9\)

The acceleration of the particle is given by the derivative of its velocity function: a(t) = v'(t) = 6t - 12

Now, to find the maximum displacement, we need to find the time at which the particle comes to rest.

This occurs when its velocity is zero:

\(3t^2 - 12t + 9 = 0\)

Simplifying this equation, we get:

\(t^2 - 4t + 3 = 0\)

This quadratic equation factors as:

(t - 1)(t - 3) = 0

So the particle comes to rest at t = 1 or t = 3.

Next, we need to determine whether the particle is at a maximum or minimum at each of these times.

To do this, we look at the sign of the acceleration:

When t = 1, a(1) = 6(1) - 12 = -6, which is negative.

Therefore, the particle is at a maximum at t = 1.

When t = 3, a(3) = 6(3) - 12 = 6, which is positive.

Therefore, the particle is at a minimum at t = 3.

Finally, we need to find the displacement of the particle at each of these times:

\(y(1) = 1^3 - 6(1)^2 + 9(1) = 4\)

\(y(3) = 3^3 - 6(3)^2 + 9(3) = 0.\)

Answer: 2.223 billion years old

Step-by-step explanation:

since 71 percent of the rock is remaining, the half life hasn't been reached yet. Hence, we know uranium isn't 4.5 billion years old yet. However, every-time 4.5 billions years pass, the rock get smaller by 2 times(a scale factor of 1/2). Hence, you can express that in a log equation:

\(\log_{2}(100/(percent of rock remaining))=\) Fraction of 4.5 billions years of time passed

\(\log_{2}(100/50)=1\)   ==> 100% of 4.5 billion years passed. When 50% of rock remains, 4.5 billion years have passed.

\(\log_{2}(100/100)\) =

\(\log_{2}(1)=0\)   ==> 0% of 4.5 billion years passed. When the rock hasn't decayed at all yet, that means that it is 0 years old.

\(\log_{2}(100/71)=0.494\)   ==> 49.4 % of 4.5 billion years passed

Answer:

2. w = -3

4. c = -2

6. r = 7

8. n = 4

Step-by-step explanation:

It's hard to read the photo, but I'll try.

2.

\( 2^{w + 4} \times 2^{4w + 6} = 2^{2w + 1} \)

On the left side, you have a product of 2 powers with the same base.

Give the same base and add the exponents, as in the rule

\( a^m \times a^n = a^{m + n} \)

You get on the left side 2 to the sum of the exponents.

\( 2^{w + 4 + 4w + 6} = 2^{2w + 1} \)

Simplify the long exponent on the left side.

\( 2^{5w + 10} = 2^{2w + 1} \)

Now we have another rule we can use. If two powers are equal, and their bases are equal, then the exponents must be equal.

Here, 2 to the power 5w + 10 equals 2 to the power 2w + 1. Since both bases are 2 and are equal, then the exponents must be equal.

5w + 10 = 2w + 1

Subtract 2w from both sides. Subtract 10 from both sides.

3w = -9

Divide both sides by 3.

w = -3

4.

\( \dfrac{1}{5} = 5^{2c + 3} \)

We need to write the left side as a power of 5. Then we equate the exponents like we did in problem 2.

Recall the rule:

\( a^{-n} = \dfrac{1}{n} \)

Apply this rule to the left side in reverse.

\( 5^{-1} = 5^{2c + 3} \)

Now we have two powers that are equal, both having the same base, 5, so the exponents must be equal.

2c + 3 = -1

2c = -4

c = -2

6.

\( 216 = 6^{2r - 11} \)

This is the same idea as problem 4. Write the left side as a power of 6.

\( 6^3 = 6^{2r - 11} \)

\( 2r - 11 = 3 \)

\( 2r = 14 \)

\( r = 7 \)

r = 7

8.

\( 4^{n} \times 4^{2n - 9} = 64 \)

This problem is similar to problem 2.

\( 4^{n + 2n - 9} = 4^3 \)

\( 4^{3n - 9} = 4^3 \)

3n - 9 = 3

3n = 12

n = 4

The solution to the equation 3(x-6) - 1/2(8x+10) = -25 is x = 2.

To simplify the equation 3(x-6) - 1/2(8x+10) = -25, we can start by applying the distributive property and then combining like terms.

First, let's distribute the 3 and the -1/2 to the terms inside the parentheses:

3(x-6) - 1/2(8x+10) = 3x - 18 - (4x + 5)

Now, let's simplify further by combining like terms:

3x - 18 - 4x - 5 = -x - 23

So, the simplified equation is -x - 23 = -25.

To solve for x, we can isolate the variable by adding 23 to both sides of the equation:

-x - 23 + 23 = -25 + 23

This simplifies to:

-x = -2

Finally, we can solve for x by multiplying both sides of the equation by -1:

(-1)(-x) = (-1)(-2)

This gives us:

x = 2

Therefore, the solution to the equation 3(x-6) - 1/2(8x+10) = -25 is x = 2.

a. This is a two-tailed test.

b. P-value = 0.0436 (rounded to three decimal places).

Given:

Test statistic (z) = 1.72

Null hypothesis (\(H_0\)): p = 0.342

Significance level (α) = 0.01

a. To identify the hypothesis test, we need to determine whether it is a two-tailed, left-tailed, or right-tailed test. Since the alternative hypothesis is stated as p ≠ 0.342, it indicates a two-tailed test. This means we are testing for deviations in both directions.

b. To find the p-value for a two-tailed test, we need to calculate the area in both tails beyond the absolute value of the test statistic.

Using a standard normal distribution table or a statistical calculator, we can find the cumulative probability associated with a z-value of 1.72. The cumulative probability is approximately 0.9564.

The area in one tail is (1 - 0.9564) / 2 = 0.0218.

Since this is a two-tailed test, the p-value is twice the area in one tail, which gives us p-value = 2 * 0.0218 = 0.0436.

To evaluate the integral of the given function, we will use the following terms: evaluate, dx, and integral.

To evaluate the integral ∫10 dx (x - 1/(x^2 + 9)), we need to find the anti derivative of the function and then evaluate it. First, let's rewrite the function as: 10x - 10/(x^2 + 9)

Now, we can find the integral of each term separately: ∫(10x) dx - ∫(10/(x^2 + 9)) dx For the first term, the integral of 10x is: (10/2)x^2 + C1 For the second term, we can use a substitution to find the integral. Let u = x^2 + 9, then du = 2x dx.

So, we have: (1/2)∫(10/u) du The integral of 10/u is 10ln|u|, so we have: (1/2)(10ln|u|) + C2 Now, substitute back in terms of x: (1/2)(10ln|x^2 + 9|) + C2

Now, we combine the results of both integrals: (10/2)x^2 + (1/2)(10ln|x^2 + 9|) + C where C is the constant of integration. This is the evaluated integral of the given function.
