Answer:

D

Step-by-step explanation:

y - x = - 4 ( add x to both sides )

y = x - 4 → (1)

- 4x - 6y = - 16 → (2)

substitute y = x - 4 into (2)

- 4x - 6(x - 4) = - 16

- 4x - 6x + 24 = - 16

- 10x + 24 = - 16 ( add 24 to both sides )

- 10x = - 40 ( divide both sides by - 10 )

x = 4

substitute x = 4 into (1)

y = 4 - 4 = 0

solution is (4, 0 )

Answer:

\(x = 4 \: and \: y = 0 \\ \)

D. (4,0)

Step-by-step explanation:

\(y - x = - 4 \\ - 4x - 6y = - 16 \\ \\ y = x - 4\)

since y is x-4, we can substitute it into the second equation

\( - 4x - 6(x - 4) = - 16 \\ - 4x - 6x + 24 = - 16 \\ - 10x + 24 = - 16 \\ - 10x = - 16 - 24 \\ - 10x = - 40 \\ \frac{ - 10} {- 10} x = \frac{ - 40}{ - 10} \\ \\ x = 4\)

Since x=4, we can now find y:

\(- 4x - 6y = - 16 \\ - 4(4) - 6y = - 16 \\ - 16 - 6y = - 16 \\ \\ \frac{ - 6}{ - 6}y = \frac{ - 16 + ( - 16)}{ - 6} \\ \\ y = \frac{0}{6} \\ \\ y = 0 \)

Therefore (4,0) is the answer

Answer:

Less greater

Step-by-step explanation:

Firstly, let's solve:

\(\frac{5}{6}\times2\frac{1}{5}\)

Convert to improper fraction

\(=\frac{5}{6}\cdot \frac{11}{5}\)

Cancel common factor: 5

\(\frac{11}{6}\)

Mixed fraction

\(=1\frac{5}{6}\)

2 1/5 > 1 5/6

Therefore, 1 5/6 is less greater than 2 1/5

The volume enclosed by the two curves when revolved about the x-axis is \(\(\frac{6\pi}{5} \ln 3 - \frac{3\pi}{2} \cdot 3^{\frac{4}{5}}\).\) To find the volume when the area enclosed by the graphs of \(\(y = x^2\)\)and \(\(y = \frac{3}{x^3}\)\) is revolved about the x-axis, we can use the method of cylindrical shells.

First, let's find the points of intersection between the two curves by setting them equal to each other:

\(\[x^2 = \frac{3}{x^3}\]\)

To simplify this equation, we can multiply both sides by \(\(x^3\)\):

\(\[x^5 = 3\]\)

Now, taking the fifth root of both sides:

\(\[x = \sqrt[5]{3}\]\)

So the two curves intersect at \(\(x = \sqrt[5]{3}\)\).

To calculate the volume area enclosed by the graphs of \(\(y = x^2\)\)and \(\(y = \frac{3}{x^3}\)\) is revolved about the x-axis, we need to integrate the circumference of each cylindrical shell multiplied by its height. The height of each shell is the difference in the y-values of the two curves, and the circumference is\(\(2\pi x\)\).

Let's integrate from \(\(x = 0\)\) to \(\(x = \sqrt[5]{3}\)\):

\(\[V = \int_0^{\sqrt[5]{3}} 2\pi x \left(\frac{3}{x^3} - x^2\right) \, dx\]\)

Simplifying this expression:

\(\[V = 2\pi \int_0^{\sqrt[5]{3}} \left(\frac{3}{x} - x^3\right) \, dx\]\)

Integrating each term separately:

\(\[V = 2\pi \left[3 \ln|x| - \frac{x^4}{4}\right]_0^{\sqrt[5]{3}}\]\)

Plugging in the limits of integration:

\(\[V = 2\pi \left[3 \ln|\sqrt[5]{3}| - \frac{\sqrt[5]{3}^4}{4}\right] - 2\pi \left[3 \ln|0| - \frac{0^4}{4}\right]\]\)

Since \(\(\ln|0|\)\)is undefined, the second term on the right side is zero:

\(\[V = 2\pi \left[3 \ln|\sqrt[5]{3}| - \frac{\sqrt[5]{3}^4}{4}\right]\]\)

Simplifying further:

\(\[V = 2\pi \left[3 \ln 3^{\frac{1}{5}} - \frac{3}{4} \cdot 3^{\frac{4}{5}}\right]\]\)

Using the properties of logarithms, we can simplify the first term:

\(\[V = 2\pi \left[3 \cdot \frac{1}{5} \ln 3 - \frac{3}{4} \cdot 3^{\frac{4}{5}}\right]\]\)

\(\[V = \frac{6\pi}{5} \ln 3 - \frac{3\pi}{2} \cdot 3^{\frac{4}{5}}\]\)

So the volume enclosed by the two curves when revolved about the x-axis is \(\(\frac{6\pi}{5} \ln 3 - \frac{3\pi}{2} \cdot 3^{\frac{4}{5}}\).\)

The firefighters' formula for nozzle discharge (L) in liters per minute can be derived from the formula for the quantity of water (Q) in cubic meters per second.

The formula for the quantity of water (Q) in cubic meters per second is given by:

Q=A×V

where A is the cross-sectional area of the pipe or nozzle and V is the velocity of the water.

To convert the quantity of water from cubic meters per second to liters per minute, we need to consider that 1 cubic meter is equal to 1000 liters, and 1 minute is equal to 60 seconds.

First, we can express the quantity of water (Q) in liters per second:

\(Qx_{litres/second} = Q_{cubic metres/second} * 1000\)

Then, we can convert the quantity of water from liters per second to liters per minute:

\(Qx_{litres/secminuteond} = Q_{litres/second} * 1000\)

By substituting the value of Q from the original formula, we get:

L=A×V×1000×60

This is the firefighters' formula for nozzle discharge (L) in liters per minute. It takes into account the cross-sectional area of the nozzle and the velocity of the water, allowing firefighters to estimate the discharge rate in liters per minute for effective firefighting operations.

Step-by-step explanation:

since there is no graph it's a bit hard to answer this question, but I'll try. I can help solve the equation that represents the ratio of the two numbers:

(x + 1/2)/y = 1/3

This can be simplified to:

x + 1/2 = y/3

To graph this equation, you would need to plot points that satisfy the equation. One way to do this is to choose a value for y and solve for x. For example, if y = 6, then:

x + 1/2 = 6/3

x + 1/2 = 2

x = 2 - 1/2

x = 3/2

So one point on the graph would be (3/2, 6). You can choose different values for y and solve for x to get more points to plot on the graph. Once you have several points, you can connect them with a line to show the relationship between x and y.

(Like I said, it was a bit hard to answer this question, so I'm not 100℅ sure this is the correct answer, but if it is then I hoped it helped.)

Answer:

  (a)  $810.45

Step-by-step explanation:

You want the value of an investment of $300 earning 5% interest compounded quarterly for 20 years.

The compound interest formula tells you the value is ...

  A = P(1 +r/n)^(nt)

where P = 300, r = 0.05, n = 4, t = 20.

Using the given parameters in the given equation, you find the account value to be ...

  A = $300(1 +0.05/4)^(4·20) ≈ $810.45

Additional comment

The "rule of 72" tells you the account value will approximately double in a number of years equal to 72 divided by the interest rate percentage: 72/5 = 14.4 years. After 20 years, it will be worth more than that doubled amount, $600. This only leaves one reasonable answer choice.

Every quadratic nonresidue of p is a primitive root of p, when p = 2^k + 1 is primeIf p = 2^k + 1 is a prime number, we want to show that every quadratic nonresidue of p is a primitive root of p.

In other words, we aim to prove that if an element x is a quadratic nonresidue modulo p, then it is also a primitive root of p.

Let's assume p = 2^k + 1 is a prime number. To prove that every quadratic nonresidue of p is a primitive root of p, we can use the properties of quadratic residues and quadratic nonresidues.

A quadratic residue modulo p is an element y such that y^((p-1)/2) ≡ 1 (mod p), while a quadratic nonresidue is an element x such that x^((p-1)/2) ≡ -1 (mod p).

Now, let's consider an element x that is a quadratic nonresidue modulo p. We want to show that x is a primitive root of p.

Since x is a quadratic nonresidue, we know that x^((p-1)/2) ≡ -1 (mod p). By Euler's criterion, this implies that x^((p-1)/2) ≡ -1^((p-1)/2) ≡ -1^2 ≡ 1 (mod p).

Since x^((p-1)/2) ≡ 1 (mod p), we can conclude that the order of x modulo p is at least (p-1)/2. However, since p = 2^k + 1 is a prime, the order of x modulo p must be equal to (p-1)/2.

By definition, a primitive root of p has an order of (p-1). Since the order of x modulo p is (p-1)/2, it follows that x is a primitive root of p.
