Answer:

k=4/5

Step-by-step explanation:

(-k+2)/(1-2k) = -2   ( using the slope formula (y2-y1)/(x2-x1)  )

-k+2 = -2 (1-2k)

-k+2 = -2 + 4k

2= -2 +5k

4 = 5k

k=4/5

Answer:

Step-by-step explanation:

To find k use the formula for finding the slope of a line and equate it to the slope which is - 2

So we have

(2k, -2) and (1, - k)

\( - 2 = \frac{ - k + 2}{1 - 2k} \)

Cross multiply

That's

- 2( 1 - 2k ) = - k + 2

Expand and simplify

- 2 + 4k = - k + 2

Group like terms

4k + k = 2 + 2

5k = 4

Divide both sides by 5

k = 4/5

Step-by-step explanation:

With the given compound interests, Investment B results in greatest total amount.

What exactly is compound interest?

Compound interest is interest charged on a loan or deposit. It is the most widely utilised idea in our everyday lives. The compound interest for an amount is determined by both the principal and the interest earned over time. This is the primary distinction between compound and simple interest.

Compound interest calculation formula:

A=P(1+r/n)ⁿˣ

Where,

A Equals Amount

P stands for principal.

r = interest rate

n is the number of times interest is compounded each year.

x = time (in years)

Alternatively, the formula may be written as follows:

CI = A – P

Where CI stands for Compound Interest.

Now,

For A

principal = $3000, Rate = 7% compounded semiannualy and time = 7 years

amount=3000(1+7/200)¹⁴

A=3000*1.61

=$4856

For B

 principal = $5000, Rate = 3.2% compounded quaterly and time = 4 years

amount = 5000(1+3.2/400)¹⁶

A=5000*1.13

=$5680

hence,

           Investment B results in greatest total amount.

The probability of not choosing any women to be on the committee is 1/15. There is only 1 way to choose 2 men out of 2.

The probability of not choosing any women to be on the committee can be calculated by dividing the number of ways to choose 2 men out of 2 from the total number of ways to choose 2 members out of 6.
To calculate the number of ways to choose 2 men out of 2, we use the combination formula, which is given by:
nCr = n! / (r!(n-r)!)

In this case, n represents the total number of men (2) and r represents the number of men to be chosen (2).
So, using the combination formula, we have:
2C2 = 2! / (2!(2-2)!) = 2! / (2! * 0!) = 2! / (2! * 1) = 2 / 2 = 1

Therefore, there is only 1 way to choose 2 men out of 2.
To calculate the total number of ways to choose 2 members out of 6, we use the same combination formula:
6C2 = 6! / (2!(6-2)!) = 6! / (2! * 4!) = (6 * 5 * 4!) / (2! * 4!) = (6 * 5) / 2 = 15
Therefore, there are 15 ways to choose 2 members out of 6.
Now, to calculate the probability of not choosing any women, we divide the number of ways to choose 2 men by the total number of ways to choose 2 members: P(no women) = 1 / 15

The object will take approximately 5.4397 seconds to travel 47 feet. This can be calculated by plugging in 47 for  into the formula =2+32. This yields 1.1848 seconds.

The formula for the distance traveled by a falling object is given by d = 2t + 32t2, where d is measured in feet and t is measured in seconds. We are given that the distance traveled is 47 feet, and we are asked to find the time it takes for the object to travel this distance.

To find the time, we can plug in the given distance into the formula and solve for t:

47 = 2t + 32t2

Rearranging the equation and using the quadratic formula, we can solve for t:

32t2 + 2t - 47 = 0

t = (-2 ± √(22 - 4(32)(-47))) / (2(32))

t = (-2 ± √(6040)) / 64

t = (-2 ± 77.717) / 64

t = 1.1848 or t = -1.2466

Since time cannot be negative, we can ignore the negative solution and take the positive solution as our answer.

Therefore, it will take approximately 1.1848 seconds for the object to travel 47 feet.

Answer:

The length of the frame is 17

Step-by-step explanation:

The computation of the length of the frame is shown below:

As we know that

The perimeter of a rectangle is

= 2 (length + width)

where,

let us assume the width be x

So, the length is x - 6

And, the perimeter is 80 yards

So, now put these values to the above formula

80 yards = 2 (x - 6+ x)

80 yards = 2 (2x - 6)

80 yards = 4x - 12

92 = 4x

x = 23

So, the length of the frame is

= 23 - 6

Answer: Domain: {-5,-1,3} and Range: {3,0,-4,2}

In the context of measurement, accuracy and precision refer to two related but distinct concepts. Accuracy is the degree to which a measurement is close to the true value of what is being measured, while precision is the degree to which repeated measurements of the same quantity are close to each other.

The uncertainty of a measurement refers to the degree of doubt or lack of confidence in the result obtained from a measuring instrument. It is typically represented by an interval around the measured value that indicates the range within which the true value is likely to lie.

The accuracy of a measuring device is related to its ability to provide measurements that are close to the true value. If a measuring device is highly accurate, then its measurements will be close to the true value, and the uncertainty associated with those measurements will be relatively small. On the other hand, if a measuring device is not very accurate, then its measurements may be far from the true value, and the uncertainty associated with those measurements will be relatively large.

The precision of a measuring device is related to its ability to provide measurements that are close to each other when measuring the same quantity repeatedly. A measuring device that is highly precise will give measurements that are very close to each other, and the uncertainty associated with those measurements will be relatively small. Conversely, a measuring device that is not very precise will give measurements that are far apart, and the uncertainty associated with those measurements will be relatively large.

The probability that a 13-card hand (from a 52-card deck) has exactly 3 three-of-a-kinds (no 4-of-a-kinds and no pairs) is approximately 0.0000266 or 0.0266%.

To calculate this probability, we can first find the number of possible hands that meet the criteria. There are 13 possible ranks for the three-of-a-kinds, and for each rank, we must choose 3 out of the 4 cards of that rank.

There are then 10 remaining ranks that can be used for the other cards, and for each of these ranks, we must choose 1 out of the 4 cards of that rank. Thus, the total number of possible hands with exactly 3 three-of-a-kinds is:

(13 choose 1) * (4 choose 3)^3 * (10 choose 10) * (4 choose 1)^10 = 3,168,192

Next, we find the total number of possible 13-card hands from a 52-card deck:

(52 choose 13) = 635,013,559,600

Finally, we divide the number of possible hands with exactly 3 three-of-a-kinds by the total number of possible hands:

3,168,192 / 635,013,559,600 ≈ 0.0000266 ≈ 0.0266%

11 years is the sum of Joey's two digits the next time his age is a multiple of Zoe's age.

Assume Chloe is c years old today, and Joey is c+1 years old today. Chloe and Zoe will be n+c and n+1 years old after n years.

Given,

(n + c) ÷ (n + 1) = 1 + ((c - 1) ÷ (n + 1))

For 9 non-negative integers, n is an integer. As a result, c - 1 has 9 positive divisors. c-1's prime factorization is either \(p^8\) or p²q². Because c - 1 < 100, the only possible solution is c - 1 = 2² × 3² = 36, from which c = 37. We may deduce that Joey is 38 years old today.

Assume Joey's age is a multiplier of Zoe's age after k years, resulting in Joey and Zoe being k + 38 and k + 1 years old, correspondingly.

Given,

(k + 38) ÷ (k + 1) = 1 + ((38 - 1) ÷ (k + 1))

For some positive integers, k is an integer. As 37 is divisible by k + 1, the only possible solution is k = 36. Infer that Joey will be k + 38 = 74 years old at that time, yielding the value 7 + 4 = 11.

The area of the walkway is 24π square meters.

To find the area of the walkway, we need to subtract the area of the inner circle from the area of the outer circle.

The inner circle has a radius of 5 meters, so its area can be calculated using the formula for the area of a circle: A_inner = π * \((r_inner)^{2}\).

A_inner = π * \(5^{2}\) = 25π square meters.

The outer circle has a radius equal to the sum of the inner radius and the width of the walkway. In this case, the outer radius is 5 + 2 = 7 meters.

The area of the outer circle can be calculated in the same way: A_outer = π * \((r_outer)^{2}\).

A_outer = π * \(7^{2}\) = 49π square meters.

Now, we can find the area of the walkway by subtracting the area of the inner circle from the area of the outer circle: A_walkway = A_outer - A_inner.

A_walkway = 49π - 25π = 24π square meters.

The area of the walkway is 24π square meters, where π (pi) is a mathematical constant approximately equal to 3.14159.

To show that `(n + 3)7 ∈ Θ(n7)`, we need to prove that `(n + 3)7 = Θ(n7)`.This can be done by showing that `(n + 3)7 = O(n7)` and `(n + 3)7 = Ω(n7)` .Now, let's prove the two parts separately:

Proof for `(n + 3)7 = O(n7)`.

We want to prove that there exists a positive constant c and a non-negative constant k such that `(n + 3)7 ≤ cn7` for all `n ≥ k`.Using the Binomial theorem, we can expand `(n + 3)7` as:```
(n + 3)7
= n7 + 7n6(3) + 21n5(3)2 + 35n4(3)3 + 35n3(3)4 + 21n2(3)5 + 7n(3)6 + 37
≤ n7 + 21n6(3) + 21n5(3)2 + 35n4(3)3 + 35n3(3)4 + 21n2(3)5 + 7n(3)6 + n7
≤ 2n7 + 21n6(3) + 21n5(3)2 + 35n4(3)3 + 35n3(3)4 + 21n2(3)5 + 7n(3)6
≤ 2n7 + 84n6 + 441n5 + 2205n4 + 10395n3 + 45045n2 + 153609n + 729
```Thus, we can take `c = 153610` and `k = 1` to satisfy the definition of big-Oh notation. Hence, `(n + 3)7 = O(n7)`.Proof for `(n + 3)7 = Ω(n7)`We want to prove that there exists a positive constant c and a non-negative constant k such that `(n + 3)7 ≥ cn7` for all `n ≥ k`.Using the Binomial theorem, we can expand `(n + 3)7` as:```
(n + 3)7
= n7 + 7n6(3) + 21n5(3)2 + 35n4(3)3 + 35n3(3)4 + 21n2(3)5 + 7n(3)6 + 37
≥ n7
```Thus, we can take `c = 1` and `k = 1` to satisfy the definition of big-Omega notation. Hence, `(n + 3)7 = Ω(n7)`.

As we have proved that `(n + 3)7 = O(n7)` and `(n + 3)7 = Ω(n7)`, therefore `(n + 3)7 = Θ(n7)`.Thus, we have shown that `(n + 3)7 ∈ Θ(n7)`.From the proof, we can see that we used the Binomial theorem to expand `(n + 3)7` and used algebraic manipulation to bound it from above and below with suitable constants. This technique can be used to prove the time complexity of various algorithms, where we have to find the tightest possible upper and lower bounds on the number of operations performed by the algorithm.

Hence, we have shown that `(n + 3)7 ∈ Θ(n7)` for non-negative integer n.

Gallons of gas used during duration of flight = 51 gallons

Number of hours spent during flight:

Arrival time - start time
