The total distance travelled by Lisa in a day is found to be 10.24 miles.

Pythagoras (born 570 BC) developed a theorem known as the Pythagorean Theorem, which is exclusively applicable to right triangles.

According to the Pythagorean Theorem, a right triangle's hypotenuse square is equal to the sum of its other two sides. The side opposite the right angle is known as the hypotenuse.

Pythagoras theorem:

a² + b² = c²

Given case:

Here,

a = b = 3 units

Put the values;

3² + 3² = c²

2*9 = c²

c = 3√2

c = 4.24

Total distance = 4.24+ 3 + 3

Total distance = 10.24 miles

Thus, the total distance travelled by Lisa in a day is found to be 10.24 miles.

Slope = \(-\frac{1}{6}\)

Step-by-step explanation:

Slope = \(\frac{Rise}{Run}\)

Slope = \(\frac{6-10}{24-0}\)

Slope = \(-\frac{1}{6}\)

Answer:

-1/6

Step-by-step explanation:

Just use the formula Y2-Y1/X2-X1.

In this case if you substitute the coordinates of those numbers, then it would be 6-10/24-0 which is 24/-4 and if you simplify it, then you get the slope -1/6.

The surface area and the volume of each solid are listed below:

Case 23

A = 216 + 153√3 cm² = 481 cm², V = 324√3 cm³ = 561.18 cm³

Case 13

A = 575π m² = 1806.42 m², V = 4000π / 3 m³ = 4188.79  m³

In this problem we must determine the surface area and the volume of each of the two solids, the following area and volume formulas are listed below:

Triangles

A = 0.5 · w · h

Rectangle

A = w · h

Circle

A = π · r²

Surface of a hemisphere

A = 2π · r²

Surface of the inclined section of a cone

A = π · r · l

Lateral surface of a cylinder

A = 2π · r · l

Volume of a prism

V = A' · l

Volume of a hemisphere

V = (2π / 3) · r³

Volume of a pyramid

V = (1 / 3) · A' · l

Where:

Now we proceed to determine the surface area and the volume of each solid:

Case 23

Surface area

A = (9 cm) · (8 cm) + (9√3 cm) · (8 cm) + (18 cm) · (8 cm) + (9 cm) · (9√3 cm)

A = 72 cm² + 72√3 cm² + 144 cm² + 81√3 cm²

A = 216 + 153√3 cm²

A = 481 cm²

V = 0.5 · (9 cm) · (9√3 cm) · (8 cm)

V = 324√3 cm³

V = 561.18 cm³

Case 13

Surface area

A = 2π · (5 m)² + 2π · (5 m) · (45 m) + π · (5 m) · (15 m)

A = 575π m²

A = 1806.42 m²

Volume

V = (2π / 3) · (5 m)³ + π · (5 m)² · (45 m) + (π / 3) · (5 m)² · (15 m)

V = 4000π / 3 m³

V = 4188.79  m³

If there is one pear for every three peaches, we can set up a ratio:

1 pear : 3 peaches

To find out how many peaches there are, we need to know how many pears there are. If we have 5 peaches, we can solve for the number of pears:

1 pear : 3 peaches = x : 5 peaches

Cross-multiplying gives us:

3x = 5

x = 5/3

So if we have 5 peaches, we would expect to have approximately 1.67 pears.

Similarly, if we have 9 peaches, we can solve for the number of pears:

1 pear : 3 peaches = x : 9 peaches

Cross-multiplying gives us:

3x = 9

x = 3

So if we have 9 peaches, we would expect to have 3 pears.

In the plan of care to prevent postoperative atelectasis, interventions should not include the use of tobacco products or exposure to secondhand smoke.

The nurse should include several interventions in the plan of care to prevent postoperative atelectasis, but there are specific interventions that should not be included. Atelectasis is the partial or complete collapse of the lung, and preventing it is crucial after surgery. Here are some interventions that should be included:

Incentive Spirometry: The nurse should encourage the client to use an incentive spirometer to promote deep breathing and lung expansion.

Early Ambulation: Encouraging the client to get out of bed and walk as soon as possible after surgery helps improve lung function.

Pain Management: Adequate pain control measures should be in place to ensure the client can take deep breaths without discomfort.

Coughing and Deep Breathing Exercises: The nurse should teach and encourage the client to perform regular coughing and deep breathing exercises to clear the airways and prevent mucus buildup.

Positioning: Proper positioning, such as elevating the head of the bed, can aid lung expansion.

What should not be included in the plan of care is the use of tobacco products or exposure to secondhand smoke, as smoking and smoke exposure are detrimental to lung health and can worsen atelectasis. These should be strictly avoided to prevent postoperative complications.

Answer:

18/10 or 1 4/5

Step-by-step explanation:

32/10 - 7/5

Remember that in order to subtract fractions, you always need to have the same denominator.

The denominator of 32/10 is 10.

The denominator of 7/5 is 5.

Are the denominator the same? In other words, are 10 and 5 equal? No, so now we need to make the denominator the same so that they are equal. To do that, find the LCM of 10 and 5.

List the LCM:

10: 10, 20, 30

5: 5, 10, 15, 20

Do you see any numbers in the list of the two numbers that are the same? Yes, 10 and 20. But since we are finding the LCM (Least common multiple), we need to use the smallest common multiple, which is 10.

Now that we found the LCM, make the denominator of 7/5 the same as 32/10.

To do that, just multiply the numerator and the denominator of 7/5 by 2; 7 times 2 is 14, 5 times 2 is 10. The final fraction should be 14/10.

Do 14/10 and 32/10 have the same denominator now? Yes, right?

Now, it’s the simple part. We now have the expression, 32/10 - 14/10.

Just subtract across, but keep the 10 as the denominato. 32 - 14 is 18. Keep the denominator 10, and you get 18/10 as your answer.

Therefore, 18/10 or 1 4/5 (if turned into a mixed fraction and simplified) is the answer. Hope this helps!

To find the probability that the difference between the numbers chosen by Jenn and Bela is at least 2, we need to consider the number of possible outcomes and the number of favorable outcomes.

- Jenn can choose any number from 1 to 20, giving us a total of 20 possible choices.
- Bela can choose any number from the remaining 19 numbers, as it needs to be distinct from Jenn's choice. This gives us 19 possible choices for Bela.
- To ensure that the difference between the chosen numbers is at least 2, we need to exclude cases where Bela chooses a number that is adjacent to Jenn's choice. For example, if Jenn chooses 5, Bela cannot choose 4 or 6.

To calculate the number of favorable outcomes, we subtract the number of unfavorable outcomes from the total number of outcomes:
- There are 19 numbers that Bela can choose from (excluding the number chosen by Jenn).
- Out of these 19 choices, there are 2 adjacent numbers to Jenn's choice (the number before and the number after).
- So, the number of unfavorable outcomes is 2.

Therefore, the number of favorable outcomes is 19 - 2 = 17.

The probability that the difference between the numbers chosen by Jenn and Bela is at least 2 is given by the ratio of the number of favorable outcomes to the total number of outcomes.
- The total number of outcomes is 20 * 19 = 380.
- The probability is therefore 17/380.

So, the answer in the form m/n is 17/380.

Step-by-step explanation:

The forces \(F_3\) that must act on the object so that the sum of the forces is zero are \(F_3\) = (-10, -10, -12).

To find the forces \(F_3\) that must act on the object so that the sum of the forces is zero, we need to find a vector \(F_3\) that satisfies the equation

\(F_1 + F_2 + F_3 = 0.\)

Given the forces:

\(F_1\) = (10, 6, 3)

\(F_2\) = (0, 4, 9)

We can rearrange the equation to solve for \(F_3\):

\(F_3 = -F_1 - F_2\)

Now, let's calculate \(F_3\):

\(F_3\) = -(10, 6, 3) - (0, 4, 9)

  = (-10, -6, -3) - (0, 4, 9)

  = (-10-0, -6-4, -3-9)

  = (-10, -10, -12)

Therefore, the forces \(F_3\) that must act on the object so that the sum of the forces is zero are \(F_3\) = (-10, -10, -12).

Since we are lοοking fοr a negative sοlutiοn, the answer is x = -6.

In mathematics, an equatiοn is a statement that twο expressiοns are equal. An equatiοn usually cοntains οne οr mοre variables, which are placehοlders fοr unknοwn values. The variables can be represented by letters, such as x, y, z, and sο οn.

Tο find the pοsitive sοlutiοn tο the equatiοn \(y=6x^2-54\), we can set y tο 0 and sοlve fοr x as fοllοws:

\(0 = 6x^2 - 54\)

Adding 54 tο bοth sides:

\(54 = 6x^2\)

Dividing bοth sides by 6:

\(9 = x^2\)

Taking the square rοοt οf bοth sides:

x = ±3

Since we are lοοking fοr a pοsitive sοlutiοn, the answer is x = 3.

Tο find the negative sοlutiοn tο the equatiοn \(y =\frac{1}{2}x^2+x-12\), we can set y tο 0 and sοlve fοr x as fοllοws:

\(0 = \frac{1}{2}x^2 + x - 12\)

Multiplying bοth sides by 2 tο get rid οf the fractiοn:

The expected value of the estimator over many random samples would be equal to the true population slope.

As per the definition of the unbiased estimator, we know that the estimator is said to be unbiased if the expected value of the estimator is equal to the population parameter. This means the expected value of the estimator over many random samples would be equal to the true population slope.

In probability theory, the expected value (also called expected value, expected value, mathematical expected value, mean, mean, or first moment) is a generalization of weighted average. Informally, the expected value is the arithmetic mean of a large number of independently selected random variables.

To find the expected value E(X) or mean μ of a discrete random variable X, simply multiply each value of the random variable by its probability and add the products. The formula is given as E(X) = μ = ∑ x P(x).
