To eliminate the roots in 1.1 and 1.2, we can use trigonometric substitution. In 1.1, we can substitute x = 4 sin(theta) to eliminate the root of 4. In 1.2, we can substitute z = 7 sin(theta) to eliminate the root of 7.

1.1. V64+2 + 1 We can substitute x = 4 sin(theta) to eliminate the root of 4. This gives us:

V64+2 + 1 = V(16 sin^2(theta) + 2 + 1) = V16 sin^2(theta) + V3 = 4 sin(theta) V3 1.2. V4z2 – 49

We can substitute z = 7 sin(theta) to eliminate the root of 7. This gives us:

V4z2 – 49 = V4(7 sin^2(theta)) – 49 = V28 sin^2(theta) – 49 = 7 sin(theta) V4 – 7 = 7 sin(theta) (2 – 1) = 7 sin(theta)

Here is a more detailed explanation of the substitution:

In 1.1, we know that the root of 4 is 2. We can substitute x = 4 sin(theta) to eliminate this root. This is because sin(theta) can take on any value between -1 and 1, including 2.

When we substitute x = 4 sin(theta), the expression becomes V64+2 + 1 = V(16 sin^2(theta) + 2 + 1) = V16 sin^2(theta) + V3 = 4 sin(theta) V3

In 1.2, we know that the root of 7 is 7/4. We can substitute z = 7 sin(theta) to eliminate this root. This is because sin(theta) can take on any value between -1 and 1, including 7/4.

When we substitute z = 7 sin(theta), the expression becomes: V4z2 – 49 = V4(7 sin^2(theta)) – 49 = V28 sin^2(theta) – 49 = 7 sin(theta) V4 – 7 = 7 sin(theta)

Answer: 9,585

Step-by-step explanation:

Answer:

$9,585.00

6.5x9000 over 100

For solving this question, you need to apply trigonometric ratios and/or Pythagoras Theorem for each of the right triangles.

A triangle is classified as a right triangle when it presents one of your angles equal to 90º.  In this triangle from the trigonometric ratios or the Pythagoras Theorem (\(hypotenuse^2=(side_1)^2 + (side_2)^2\)), it is possible finding angles or sides.

The main trigonometric ratios are presented below.

\(sin(x)=\frac{opposite\,side}{hypotenuse} \\ \\ cos(x)=\frac{adjacent\,side}{hypotenuse}\\ \\ tan(x)=\frac{sin(x)}{cos(x)}= \frac{opposite\,side}{hypotenuse}* \frac{hypotenuse}{adjacent\,side}= \frac{opposite\,side}{adjacent\,side}\)

                                     \(hypotenuse^2=(side_1)^2 + (side_2)^2\\ \\ 29^2=20^2+s^2\\ \\ 841=400+s^2\\ \\ s^2=441\\ \\ s=\sqrt{441}=21\)

For angle D you will find:

                        \(sin(D)=\frac{opposite\,side}{hypotenuse}=\frac{20}{29} \\ \\ cos(D)=\frac{adjacent\,side}{hypotenuse}=\frac{21}{29} \\ \\ tan(D)=\frac{sin(D)}{cos(D)}= \frac{opposite\,side}{adjacent\,side}=\frac{20}{21}\)

For angle E you will find:

                       \(sin(E)=\frac{opposite\,side}{hypotenuse}=\frac{21}{29} \\ \\ cos(E)=\frac{adjacent\,side}{hypotenuse}=\frac{20}{29} \\ \\ tan(E)=\frac{sin(E)}{cos(E)}= \frac{opposite\,side}{adjacent\,side}=\frac{21}{20}\)

The question gives an angle (62°) and the adjacent side (25) from the angle 62° of the right triangle. Therefore, you can find x from the trigonometric ratio of tan (62°):

                           \(tan(62^{\circ \:})= \frac{opposite\,side}{adjacent\,side}=\frac{x}{25}\\ \\ \tan \left(62^{\circ \:}\right)=1.881 \\ \\ Then,\\ \\ 1.881=\frac{x}{25} \\ \\ x=25*1.881=47.025\\ \\ x=47.0\)

The question gives an angle (26°) and the opposite side (11) from the angle 26° of the right triangle. Therefore, you can find x from the trigonometric ratio of sin (26°):

                          \(sin(26^{\circ \:})=\frac{opposite\,side}{hypotenuse}=\frac{11}{x} \\ \\ sin(26^{\circ \:})=0.438\\ \\ Then,\\ \\ 0.438=\frac{11}{x} \\ \\ 0.438x=11\\ \\ x=\frac{11}{0.438} \\ \\ x=25.1\)

The question gives an angle (48°) and the hypotenuse (32) of the right triangle. Therefore, you can find x from the trigonometric ratio of sin (48°):

                        \(sin(48^{\circ \:})=\frac{opposite\,side}{hypotenuse}=\frac{x}{32} \\ \\ sin(48^{\circ \:})=0.743\\ \\ Then,\\ \\ 0.743=\frac{x}{32} \\ \\ x=32*0.743\\ \\ x=23.8\)

The question gives an angle (12°) and the adjacent side (29) from the angle 12° of the right triangle. Therefore, you can find x from the trigonometric ratio of cos (12°):

                           \(cos(12^{\circ \:})=\frac{adjacent\,side}{hypotenuse}=\frac{29}{x} \\ \\ cos(12^{\circ \:})=0.978\\ \\ Then,\\ \\ 0.978=\frac{29}{x} \\ \\ 0.978x=29\\ \\ x=\frac{29}{0.978} \\ \\ x=29.6\)

The question gives the adjacent side (14) from the angle x and the hypotenuse (15) of the right triangle. Therefore, you can find x from the trigonometric ratio of cos(x) :

                        \(cos(x)=\frac{adjacent\,side}{hypotenuse}=\frac{14}{15} \\ \\ cos(x)=0.933\)

After that, you should calculate the arccos(x).

                      \(\arccos \left(\frac{14}{15}\right)=21.0^{\circ \:}\\ \\ Then,\\ \\ x=21.0^{\circ \:}\)

The question gives the adjacent side (23) from angle x and the opposite side (19) from angle x of the right triangle. Therefore, you can find x from the trigonometric ratio of tan (x) :

                        \(tan(x)= \frac{opposite\,side}{adjacent\,side}=\frac{19}{23}\\ \\ \tan \left(x}\right)=0.826\)

After that, you should calculate the arctan(x).

                      \(\arctan \left(\frac{19}{23}\right)=39.6^{\circ \:}\\ \\ Then,\\ \\ x=39.6^{\circ \:}\)

The question gives the adjacent side (9) from angle x and the hypotenuse (17) of the right triangle. Therefore, you can find x from the trigonometric ratio of cos(x) :

                        \(cos(x)=\frac{adjacent\,side}{hypotenuse}=\frac{9}{17} \\ \\ cos(x)=0.529\)

After that, you should calculate the arccos(x).

                      \(\arccos \left(\frac{9}{17}\right)=58.0^{\circ \:}\\ \\ Then,\\ \\ x=58.0^{\circ \:}\)

The question gives the opposite side (43) from angle x and the hypotenuse (45) of the right triangle. Therefore, you can find x from the trigonometric ratio of sin(x) :

                        \(sin(x)=\frac{opposite\,side}{hypotenuse}=\frac{43}{45} \\ \\ sin(x)=0.956\)

After that, you should calculate the arcsin(x).

                      \(\arcsin \left(\frac{43}{45}\right)=72.9^{\circ \:}\\ \\ Then,\\ \\ x=72.9^{\circ \:}\)

If 1(1/4) pound of turkey is sold for $9, then the unit-price of the turkey is $7.20 per pound.

The "Unit-Price" is defined as the price of a single unit or item of a product, typically expressed in terms of a standard unit of measurement, such as price per pound, price per liter, or price per piece.

To find the unit price of turkey in the package, we need to divide the total cost of the package by the weight of the turkey in the package.

First, we need to convert 1(1/4) pounds to a decimal, which is 1.25 pounds.

Then, we can find the unit price by dividing the total-cost of $9 by the weight of the turkey in the package:

⇒ Unit price = (Total cost)/(Weight of turkey in package),

⇒ Unit price = $9/1.25 pounds,

⇒ Unit price = $7.20 per pound,

Therefore, the unit price of turkey in the package is $7.20 per pound.

The correct answer is it would take approximately 0.000012 seconds (or 12 microseconds) for the laptop to receive a packet of MTU size (1500 bytes) with a network speed of 1 Gbps.

To determine the time it will take for a laptop to receive a packet of MTU size (1500 bytes), we need to consider the data transfer rate or network speed.

Let's assume the network speed is given in bits per second (bps). We'll need to convert the packet size from bytes to bits and then divide it by the network speed to calculate the time.

First, let's convert the packet size from bytes to bits:

Packet size = 1500 bytes

1 byte = 8 bits

1500 bytes * 8 bits/byte = 12000 bits

Now, we need to divide the packet size by the network speed to calculate the time:

Time = Packet size / Network speed

For example, if the network speed is 1 Gbps (1 gigabit per second), the calculation would be:

Time = 12000 bits / (1 Gbps) = 12000 / (10^9) seconds = 0.000012 seconds

Therefore, it would take approximately 0.000012 seconds (or 12 microseconds) for the laptop to receive a packet of MTU size (1500 bytes) with a network speed of 1 Gbps.

James will fully clear the loan after approximately 12 years when the remaining balance reaches zero.

To determine the number of years it will take for James to fully clear the loan, we need to calculate the remaining balance after each payment and divide the initial loan amount by the annual payment until the remaining balance reaches zero.

The loan amount is 9000 euros, and James pays off 770 euros each year. Since the interest is charged at a rate of 3% of the original amount per annum, the interest for each year will be \(0.03 \times 9000 = 270\) euros.

In the first year, James pays off 770 euros, and the interest on the remaining balance of 9000 - 770 = 8230 euros is \(8230 \times 0.03 = 246.9\)euros. Therefore, the remaining balance after the first year is 8230 + 246.9 = 8476.9 euros.

In the second year, James again pays off 770 euros, and the interest on the remaining balance of 8476.9 - 770 = 7706.9 euros is \(7706.9 \times 0.03 = 231.21\) euros. The remaining balance after the second year is 7706.9 + 231.21 = 7938.11 euros.

This process continues until the remaining balance reaches zero. We can set up the equation \((9000 - x) + 0.03 \times (9000 - x) = x\), where x represents the remaining balance.

Simplifying the equation, we get 9000 - x + 270 - 0.03x = x.

Combining like terms, we have 9000 + 270 = 1.04x.

Solving for x, we find x = 9270 / 1.04 = 8913.46 euros.

The dimensions of the rectangle that minimize the perimeter are 18 feet by 18 feet.

To find the dimensions of a rectangle with an area of 324 square feet and the smallest possible perimeter, we need to minimize the perimeter while maintaining the given area. The area of a rectangle is given by the formula:

Area = length × width

Now, let's find the dimensions that result in the smallest perimeter.


The dimensions of the rectangle that minimize the perimeter are 18 feet by 18 feet.

1. We know the area is 324 square feet, so we can write the equation:

  324 = length × width

2. To minimize the perimeter, the rectangle should be as close to a square as possible because a square has the smallest possible perimeter for a given area.

3. Find the factors of 324 to determine which pair of numbers is closest to being equal. The factors are:

  1×324, 2×162, 3×108, 4×81, 6×54, 9×36, 12×27, and 18×18

4. Among these factor pairs, 18×18 is the closest to being equal, so the dimensions are 18 feet by 18 feet.

5. The smallest possible perimeter is achieved when the rectangle is a square with side lengths of 18 feet. The perimeter can be calculated as:

  Perimeter = 2 × (length + width) = 2 × (18 + 18) = 2 × 36 = 72 feet

So, the dimensions of the rectangle with an area of 324 square feet and the smallest possible perimeter are 18 feet by 18 feet, and the perimeter is 72 feet.

The width of the new rectangular field would be 0 meters, which means it would essentially be a line segment.

To find the length and width of another rectangular field that has the same perimeter but a larger area, we can use the following steps:

1. Calculate the perimeter of the given rectangular field:

  Perimeter = 2 * (Length + Width)

            = 2 * (120 meters + 80 meters)

            = 2 * 200 meters

            = 400 meters

2. Divide the perimeter by 2 to find the equal sides of the new rectangular field. Since the perimeter is divided equally into two sides, each side would be half of the perimeter length:

  Side length = Perimeter / 2

             = 400 meters / 2

             = 200 meters

3. Now, we have the side length of the new rectangular field. However, we need to determine the length and width that would yield a larger area. One way to achieve this is to make one side longer and the other side shorter.

4. Let's assume the length of the new rectangular field is 200 meters. Since both sides have the same length, the width can be calculated using the formula for the perimeter:

  Width = Perimeter / 2 - Length

        = 400 meters / 2 - 200 meters

        = 200 meters - 200 meters

        = 0 meters

5. Therefore, the width of the new rectangular field would be 0 meters, which means it would essentially be a line segment. However, note that the question asks for a rectangular field with a larger area. Since the width cannot be zero, we can conclude that it is not possible to have a rectangular field with the same perimeter but a larger area than the given field.

In summary, it is not possible to find another rectangular field with the same perimeter but a larger area than the rectangular field with dimensions 80 meters wide and 120 meters long.

He charges $6 per hour and pays $4 in equipment fees.

To find:

The possible numbers of hours Manuel could trim trees.

Solution:

Let t be the numbers of hours Manuel could trim trees.

Earnings of Manuel in one hour = $6

Earnings of Manuel in t hour = $6t

He pays $4 in equipment fees. So, we will subtract this from the income.

\(\text{Total earnings}=6t-4\)

Manuel wants to earn at least $44 trimming trees. It means, total earnings must be greater than or equal to 44.

\(6t-4\geq 44\)

\(6t\geq 44+4\)

\(6t\geq 48\)

Divide both sides by 6.

\(t\geq \dfrac{48}{6}\)

\(t\geq 8\)

The amount the restaurant needs to earn on Sunday to average $1000 per day over the three-day period is $819.

What is average ?

The average is the ratio of the sum of the number of a given set of values to the total number of values present in the set.

It is given that restaurant earns $1073 on Friday and $1108 on Saturday.

The amount which restaurant needs to earn on Sunday to average $1000 per day over the three-day period can be calculated by finding the average.

The average is given by ratio of sum of amount on each day from Friday to Sunday and divide it by number of days.

Let's assume amount earn on Sunday is $x.

So ,

\(\frac{1073 + 1108 + x}{3}\) = 1000

1073 + 1108 + x = (1000 × 3)

2181 + x = 3000

Let's solve this equation to get the value of x.

x = 3000 - 2181

x = $819

So , amount earn by restaurant is $819.
