Step-by-step explanation:

given things  : 1. height of cone  = 22* 1/4 feet or  89/4 feet

                       2.  diameter of cylinder = 2* 2/5 times of height

                                                          =  12/5 times of height or 12/5 * 89/4

                                                           = 89*3/5 feet

now formula of volume of cone =  Pi R² * H

                                                       = (3.14) ( D/2)² * H

                                                       = (3.14)*  (89*3/10)² * 89/4

                                                       = (3.14) * (26.7)² * 22.25

                                                       = (3.14) * 712.89 * 22.25

                                                       =  (49806.06)

The value of k is 1, the volume of the parallelepiped is 12 + 4λ, and the vector component of a + c orthogonal to c is (1,1,1.5).

a) Here the area of the parallelogram determined by d and e is given as 10. The area of the parallelogram is given as `|d×e|`.

We have,

d=(2,4)

and e=(4k,3k)

Then,

d×e= (2 * 3k) - (4 * 4k) = -10k

Area of parallelogram = |d×e|

= |-10k|

= 10

As we know, area of parallelogram can also be given as,

|d×e| = |d||e| sin θ

where, θ is the angle between the two vectors.

Then,10 = √(2^2 + 4^2) * √((4k)^2 + (3k)^2) sin θ

⇒ 10 = √20 √25k^2 sin θ

⇒ 10 = 10k sin θ

∴ k sin θ = 1

Therefore, sin θ = 1/k

Hence, the value of k is 1.

Part(b) The volume of the parallelepiped determined by vectors a, b and c is given as,

| a . (b × c)|

Here, a=(1,1,2),

b=(5,3,λ), and

c=(4,4,0)

Therefore,

b × c = [(3 × 0) - (λ × 4)]i + [(λ × 4) - (5 × 0)]j + [(5 × 4) - (3 × 4)]k

= -4i + 4λj + 8k

Now,| a . (b × c)|=| (1,1,2) .

(-4,4λ,8) |=| (-4 + 4λ + 16) |

=| 12 + 4λ |

Therefore, the volume of the parallelepiped is 12 + 4λ.

Part(c) The vector component of a + c orthogonal to c is given by [(a+c) - projc(a+c)].

Here, a=(1,1,2) and

c=(4,4,0).

Then, a + c = (1+4, 1+4, 2+0)

= (5, 5, 2)

Now, projecting (a+c) onto c, we get,

projc(a+c) = [(a+c).c / |c|^2] c

= [(5×4 + 5×4) / (4^2 + 4^2)] (4,4,0)

= (4,4,0.5)

Therefore, [(a+c) - projc(a+c)] = (5,5,2) - (4,4,0.5)

= (1,1,1.5)

Therefore, the vector component of a + c orthogonal to c is (1,1,1.5).

Conclusion: The value of k is 1, the volume of the parallelepiped is 12 + 4λ, and the vector component of a + c orthogonal to c is (1,1,1.5).

In parallelogram ABCD, ∠b = 55°; ∠d = 55. So, the correct answer is (a).

We know that opposite angles of a parallelogram are congruent. In another words, opposite angles of  parallelogram are equal. Therefore, we equate the angle B and angle D to each other and solve.

angle B = angle D

2n + 15 = 3n - 15

n = 30

The value of n is 30.

Now we can find the measures of angles B and D:

angle B = 2n + 15 = 2(30) + 15 = 75 degrees

angle D = 3n - 15 = 3(30) - 15 = 75 degrees

Therefore, the answer is (a) ∠b = 55°; ∠d = 55

Answer:

2,678,400

Step-by-step explanation:

July : 31 days

Day : 24 hours

Hours : 60 minutes

Minute 60 seconds

1. 60 × 60 : 3600

2. 3600 × 24 : 86400

3. 86400 × 31 : 2678400

Pls like I got it wrong the first time :')

The month of July has 2,678,400 seconds as per the concept of multiplication.

To calculate the number of seconds in the month of July, we need to consider that each day has 24 hours, each hour has 60 minutes, and each minute has 60 seconds. Since July has 31 days, we can perform the following calculations:

Number of hours in July: 31 days x 24 hours = 744 hours.

Number of minutes in July: 744 hours x 60 minutes = 44,640 minutes.

Number of seconds in July: 44,640 minutes x 60 seconds = 2,678,400 seconds.

Therefore, the month of July has 2,678,400 seconds. This calculation assumes that there are no leap seconds added during this period. It's worth noting that the number of seconds in a month can vary if leap seconds are inserted to adjust for discrepancies between atomic time and solar time. However, since the question does not specify any leap seconds, the calculation provided represents the standard number of seconds in the month of July.

The formula for determining the number of different ways a person can answer a survey is to multiply the number of options for each question together. In this case, the survey has 10 items and each item has 5 options on a scale of 1 to 5. There are 50 different ways a person can answer this survey.

To calculate the number of different ways a person can answer the survey, we multiply the number of options for each item together:

10 x 5 = 50

So, there are 50 different ways a person can answer this survey.

Let's break it down further:

For the first item, the person can choose from 5 options (1, 2, 3, 4, or 5).
For the second item, the person can also choose from 5 options.
Similarly, for all 10 items, the person has 5 options each.

To find the total number of different ways, we multiply the number of options for each item together:

5 x 5 x 5 x 5 x 5 x 5 x 5 x 5 x 5 x 5 = 50

Therefore, there are 50 different ways a person can answer this survey.

The probability that the chosen card is a diamond is 3/13. According to the definition of probability, which is "the degree to which something is probable; the likelihood of something happening or being the case," there is a 1/13 chance that none of the cards will be diamonds.

Probability is simply the likelihood that something will happen. The likelihood or likelihood of various outcomes can be discussed when we don't know how an event will turn out. The study of events that fit into a probability distribution is known as statistics. The full range of potential outcomes is known as the sample space, or individual space, of a random experiment. The likelihood of any event occurring ranges from 0 to 1. Probability is the study of random events in mathematics, and it can be classified into four main categories: axiomatic, classical, empirical, and subjective. You could say that probability is the likelihood that a particular event will occur because probability and possibility are synonyms.

Here,

a. Given that there are 13 diamond cards, the probability that all the cards are diamonds is 3/13.

b. the likelihood that none of the 52 cards, with 13 diamond cards, are diamonds.

unused card = 52-13 = 39 = 3/39

There is a 3/13 chance that the selected card will be a diamond. There is a 1/13 chance that no cards will be diamonds, according to the definition of probability, which is "the degree to which something is probable; the likelihood of something happening or being the case."

Answer:

f(x) = -1/x^2 + 4e^x + 5x + 1 + 1/x - 4e^(-1)

Step-by-step explanation:

We can find the function f(x) by integrating f'(x) with respect to x:

â«f'(x) dx = â«(2/(x^3) + 4e^x + 5) dx

f(x) = -1/x^2 + 4e^x + 5x + C

To find the constant C, we can use the given initial conditions:

f(-1) = 1 = -1/(-1)^2 + 4e^(-1) - 5 + C

C = 1 + 1/1 - 4e^(-1)

f(x) = -1/x^2 + 4e^x + 5x + 1 + 1/x - 4e^(-1)

Therefore, the function f(x) is:

f(x) = -1/x^2 + 4e^x + 5x + 1 + 1/x - 4e^(-1)

Caroline is planting her first 7 flowers in 4 minutes and then past 12 minutes, she plants 21 different flowers. That suggests that she is planting the flowers following the given equation  y=(7/4)x.

The dependent variable is defined as the variable whose evaluation of the independent variable determines the quality of the dependent variable. That is, it is consistently claimed that the word variable's estimate depends on the mathematical condition's free variable.

Let Caroline plant y flowers in x minutes.

By using the unitary method we can observe that

4 minutes  → 7 flowers

⇒ 1 minute → 7/4 flowers

⇒ x minutes → (7/4)x flowers

Hence, Caroline is planting y=(7/4)x flowers in x minutes. And y=(7/4)x this equation represents the variation perfectly.

NOTE: We took the number of flowers planted as y because it is a dependent variable. The number of flowers depends on the time elapsed.

b. Approximately 20% of all mice have a mass of more than 19.43 grams.

a. Using a standard normal distribution table, we can find the z-score that corresponds to a cumulative probability of 0.25. The closest value we can find in the table is 0.67.

z = 0.67

Substituting the values back into the formula, we can solve for x:

x = 0.67 * 0.14 + 19.3

x ≈ 19.402 grams

b) In order to find the mass at which 20% of mice have a higher mass, we need to find the z-score associated with the cumulative probability of 0.80 (since 1 - 0.20 = 0.80). The closest value in the standard normal distribution table is 0.84.

z = 0.84

x = 0.84 * 0.14 + 19.3

Answer:

Step-by-step explanation:

To calculate the concentrations of all species present in a 0.72 M NH3 solution (Kb=1.8×10−5), we can use the principles of the equilibrium expression for the dissociation of NH3 in water.

NH3 (ammonia) is a weak base that reacts with water to form NH4+ (ammonium) and OH- (hydroxide) ions. The equilibrium expression for this reaction can be written as:

NH3 + H2O ⇌ NH4+ + OH-

Since the initial concentration of NH3 is 0.72 M, we can assume that x mol/L of NH3 will dissociate to form x mol/L of NH4+ and OH-. Therefore, the concentrations of NH4+ and OH- will also be x mol/L.

To calculate the value of x, we can use the Kb expression, which relates the equilibrium constant to the concentrations of the species. In this case, Kb = [NH4+][OH-]/[NH3]. Substituting the known values, we have:

1.8×10−5 = x * x / (0.72 - x)

Solving this equation will give us the value of x, which represents the concentration of NH4+ and OH-. Finally, we can express the concentrations of NH3, NH4+, and OH- using two significant figures, separated by commas, based on the calculated value of x.

Permutation is the number of ways a number of k objects can be selected from a set of n objects while giving relevance to the order selection.

The two ways of forming subsets from selecting a group of objects from a set are through combination and permutation. The act of selecting objects and arranging them into some kind of order is the process of permutation. On contrary, combination is the type of selecting objects wherein the order is not really important.

The selection process stated in this problem is permutation. Let P be the number of ways a k number of objects is chosen from a set of n objects.

For a permutation that allows repetition or replacement of the chosen object:

P= n*n*(k number of objects that will be selected)= \(n^{k}\)

For a permutation that does not allow repetition or replacement of chosen object:

\(P = \frac{n!}{(n-k)!}\)

Factorial is used to indicate the descending number of choices every time an object is selected. In order to select a k number of things, factorial n will be divided by the factorial of n-k.
