Step-by-step explanation:

the given equation defines a paraboloid that lies below the plane z=0. Specifically, it is situated above the xy-plane, which means that the z-values of all points on the surface are greater than or equal to zero.

we can break down the equation z=18-2x^2-2y^2. This equation represents a paraboloid with its vertex at (0,0,18) and axis of symmetry along the z-axis. The first term 18 is the z-coordinate of the vertex and the last two terms -2x^2 and -2y^2 determine the shape of the paraboloid.

Since the coefficient of x^2 and y^2 terms are negative, the paraboloid is downward facing and opens along the negative z-axis. Therefore, all points on the paraboloid have z-values less than 18. Additionally, since the paraboloid is situated above the xy-plane, its z-values are greater than or equal to zero.

the paraboloid defined by the equation z=18-2x^2-2y^2 is situated below the plane z=0 and above the xy-plane. Its vertex is at (0,0,18) and it opens along the negative z-axis.

Answer: See explanation

Step-by-step explanation:

x=-(2-2*the square root of 6)/5, about 0.58

or

x=-(2+2*the square root of 6)/5, about -1.38

The values of the x from equation  \(5x^2+4x-4=0\) are  x = 0.5798 and -1.38.

Given that:

Equation:  \(5x^2+4x-4=0\)

To find the values of x that satisfy the equation \(5x^2+4x-4=0\), use the quadratic formula:

\(x = \dfrac{ -b \± \sqrt{b^2 - 4ac}}{ 2a}\)

Compare the equation with \(ax^2 + bx + c = 0\).

Here, a = 5, b = 4, and c = -4.

Plugging in the values to get,

\(x = \dfrac{-4 \± \sqrt{4^2 - 4 \times 5 \times (-4)}}{2 \times 5} \\x = \dfrac{-4 \± \sqrt{16 +80}}{10} \\x = \dfrac{-4 \± \sqrt{96}}{10}\\x = \dfrac{-4 \± {4\sqrt6}}{10}\)

So the solutions for x are calculates as:

Taking positive sign,

\(x = \dfrac{-4 + {4\sqrt6}}{10}\\x = \dfrac{-4 + {9.798}}{10}\\\)

x = 5.798/10

x = 0.5798

Taking negative sign,

\(x = \dfrac{-4 - {4\sqrt6}}{10}\\x = \dfrac{-4 - {9.798}}{10}\\\)

x = -13.798/10

x = -1.38

Hence, the exact solutions for the equation  \(5x^2 + 4x - 4 = 0\)  are x = 0.5798 and -1.38.

a).  2^38 bytes of memory

b). 12 bits

c). The maximum number of entries in the single-level page table would be 2^38.

d). The size would be 2^38 * 4KB, which equals 2^20 pages.

e). The maximum number of entries it can have depends on the remaining bits of the logical address.

f). The amount of bits required to denote an index into the inner page table is obtained by subtracting the offset and outer page index bits from the logical address.

a. To address a physical memory size of 128GB (2^37 bytes), a 64-bit architecture would require 38 bits for the logical address, allowing access to a maximum of 2^38 bytes of memory.

b. Given that the page size is 4KB (2^12 bytes), 12 bits would be needed to specify the displacement into a page. This means that the lower 12 bits of the logical address would be used for page offset or displacement.

c. With a single-level page table, the maximum number of entries would be equal to the number of possible logical addresses. In this case, since the logical address requires 38 bits, the maximum number of entries in the single-level page table would be 2^38.

d. The size of the single-level page table is determined by the number of entries it contains. Since each entry maps to a page of size 4KB, the size of the single-level page table can be calculated by multiplying the number of entries by the size of each entry. In this case, the size would be 2^38 * 4KB, which equals 2^20 pages.

e. For a two-level page table, the size of the outer page table is determined by the number of entries it can contain. Since the outer page table uses 4KB pages, the maximum number of entries it can have depends on the remaining bits of the logical address. The number of bits used for the index into the outer page table is determined by subtracting the bits used for the inner page index and the offset from the total number of bits in the logical address.

f. The number of bits used to specify an index into the inner page table can be determined by subtracting the bits used for the offset and the bits used for the outer page index from the total number of bits in the logical address. The remaining bits are then used to specify the index into the inner page table.

The radius of the circle is 10 cm.

To find the radius of the circle in which the given central angle intercepts an arc of the given length s, we can use the formula given below:

\(r=\frac{s}{2\sin\frac{\theta}{2}}\)

where r is the radius of the circle,s is the length of the intercepted arc, andθ is the central angle in radians.

For example, if the central angle is 60 degrees and the intercepted arc length is 10 cm, we first need to convert the central angle to radians:

\(\theta = \frac{60}{180}\pi \\= \frac{\pi}{3}\)

Then we can use the formula:

\(r=\frac{s}{2\sin\frac{\theta}{2}}\\=\frac{10}{2\sin\frac{\pi}{6}}\\= \frac{10}{2(\frac{1}{2})}\\=10\\\)

Answer:

He made a profit of 40-32 = Rs 8 per copy.

He got a 25% profit in the business of copies

Step-by-step explanation:

Newton buys and sells copies in his business. He bought 12 dozen = 12*12=144 copies in Rs 4320.

He also has Rs 288 in expenses to bring the copies to his shop, thus the total cost is 4320+288=4608.

Each copy finally cost 4608/144 = Rs 32.

He sold all copies for Rs 5760, at 5760/144= Rs 40 each.

Therefore, he made a profit of 40-32 = Rs 8 per copy.

The unit kilowatt-hour measures the amount of energy used or produced, whereas the rate at which energy is transformed is measured in kilowatts.

The unit kilowatt-hour (kWh) is a measure of energy, not power. Energy is a measure of the amount of work that can be done, and is usually measured in joules. Power, on the other hand, is a measure of the rate at which energy is transformed, and is usually measured in watts.

A kilowatt-hour is the amount of energy used or produced when a power of one kilowatt is used for one hour. For example, if a 100-watt light bulb is left on for 10 hours, it will have used

100 * 10 = 1000 watt-hours or 1 kilowatt-hour of energy.

The average value of the function \(\( f(x) = 2 \cos x \)\) on the interval \(\( \left[0, \frac{\pi}{2}\right] \) is \( \frac{2}{\pi} \).\)

To find the average value of a function on a given interval, we need to calculate the definite integral of the function over that interval and then divide it by the length of the interval. In this case, the given function is \(\( f(x) = 2 \cos x \)\), and we are interested in the interval \(\( \left[0, \frac{\pi}{2}\right] \).\)

First, we calculate the definite integral of f(x)  over the interval \(\( \left[0, \frac{\pi}{2}\right] \)\). The integral of cos x is sin x , so the integral of 2 cos x  is 2 sin x . To find the definite integral, we evaluate  2 sin x  at the upper and lower limits of the interval and subtract the results.

Plugging in the upper limit \(\( \frac{\pi}{2} \)\), we get \(\( 2 \sin \left(\frac{\pi}{2}\right) = 2 \cdot 1 = 2 \)\). Plugging in the lower limit 0 , we get \(\( 2 \sin 0 = 2 \cdot 0 = 0 \)\). Therefore, the definite integral of f(x) over the interval is \(\( 2 - 0 = 2 \).\)

Next, we need to calculate the length of the interval \(\( \left[0, \frac{\pi}{2}\right] \)\). The length of an interval is determined by subtracting the lower limit from the upper limit. In this case, the length is \(\( \frac{\pi}{2} - 0 = \frac{\pi}{2} \)\).

Finally, we divide the definite integral of f(x) by the length of the interval to find the average value. Dividing 2 by \(\( \frac{\pi}{2} \)\) gives us \(\( \frac{2}{\pi} \)\), which is the average value of the function\(\( f(x) = 2 \cos x \)\) on the interval \(\( \left[0, \frac{\pi}{2}\right] \).\)

Step-by-step explanation:

The length of the rectangle is 20 m.

The width of the rectangle is 16 m.

The perimeter of a rectangle can be determined using the following formula:

Perimeter of rectangle = 2(length + width).

Let x represent the length of the rectangle. Therefore, we would have the following given parameters for the rectangle:

Length of the rectangle = x meters

Width of the rectangle = (x - 4) meters

Perimeter of the rectangle = 72 meters

We would have the following equation:

2(x + (x - 4)) = 72

Open the bracket and solve for x

2(x + x - 4) = 72

2(2x - 4) = 72

4x - 8 = 72

4x = 72 + 8

4x = 80

4x/4 = 80/4

x = 20

Length of the rectangle = x = 20 m

Width of the rectangle = (x - 4) = 20 - 4 = 16 m

The present value of the annuity is $4,813.52.

To calculate the present value of the annuity, we can use the formula for the present value of an increasing annuity:

PV = C * (1 - (1 + r)^(-n)) / (r - g)

Where:

PV = Present Value

C = Payment amount at time t=1

r = Interest rate

n = Number of payments

g = Growth rate of payments

In this case:

C = $300

r = 8% or 0.08

n = Number of payments = Last payment amount - First payment amount / Growth rate + 1 = ($1000 - $300) / $50 + 1 = 14

g = Growth rate of payments = $50

Plugging in these values into the formula, we get:

PV = $300 * (1 - (1 + 0.08)^(-14)) / (0.08 - 0.05) = $4,813.52

Therefore, the present value of this annuity is $4,813.52. This means that if we were to invest $4,813.52 today at an interest rate of 8%, it would grow to match the future cash flows of the annuity.
