a) It takes 2 seconds for the rocket to reach the maximum height, and this maximum height is of 169.6 metres.

b) The height of the rocket five seconds after it was launched is of 125.5 metres.

The vertex-form definition of a quadratic function is defined as follows:

y = a(x - h)² + k.

In which the parameters are given as follows:

In the context of this problem, the height function is defined as follows:

h(t) = -4.9(t - 2)² + 169.6.

Hence the coordinates of the vertex are given as follows:

As the leading coefficient is negative, the parabola is concave down and the vertex represents a maximum.

The height at a time of five seconds is of:

h(5) = -4.9(5 - 2)² + 169.6 = 125.5 metres.

Probability:

In statistics, probability refers the ratio of the number of outcomes in an exhaustive set of equally likely outcomes that produce a given event to the total number of possible outcomes.

Given,

Here we have a printed circuit cards are placed in a functional test after being populated with semiconductor chips. a lot contains 190 cards, and 20 are selected without replacement for functional testing.

And we need to find the following probability.

Here we have to recall the formula for probability mass function of the hypergeometric random variable X with the parameters

N = 190

n ​= 20​

and the parameter K.

And it is the following expression:

f(x) = [(K x) (140 - k 20 - x)] / (140 20)

Now, we have to Set K=20 and calculate from the probability mass function:

=> P(X≥1)=1−f(0)=0.964​

If it is important to detect a mean difference in score of one point with the probability of at least 0.90 , then the number of pairs that should be used is  10 .

What is a Probability ?

The term probability of an event  is defined as ⇒ number of favorable outcomes / total number of outcomes  .

It is given that ,

the probability is at least 0.90 ,

So , in the paired t test ,

testing mean paired difference is = 0

alpha = 0.05 , the assumed standard deviation of paired difference = 0.441

So the output is

Difference = 1 , Size = 5 power(probability) = 0.90 ,

So , the actual probability is = 0.95190

From the output above , the required sample size is n = 5 .

We observe that , under the given conditions the sample size is = 5 .

but the researcher  considered 10 pairs ,

So , the sample size 10 is used for this study .

The solution of given expression 7×(4-3) - 1+5×1/5 is 5.

The abbreviation PEMDAS is used to indicate the sequence of steps to be taken when resolving expressions with multiple operations. P is for "parentheses," E is for "exponents," M is for "multiplication," D is for division, A is for addition, and S is for subtraction.

Given that the expression 7×(4-3) - 1+5×1/5.

To solve the above expression we will use PEMDAS;

First, we use the subtraction in brackets and this process is called simplifying parenthesis,

7×(4-3) - 1+5×1/5=  7×(1) - 1+5×1/5.

Now, we use the operation multiplication,

7×(1) - 1+5×1/5 = 7 - 1+1

Now we add the terms and this process is called addition of terms,

7 - 1+ 1 = 7-2

Now, we subtract the numbers and this property is subtraction of numbers,

7 - 2 = 5.

Therefore, the solution of given expression 7×(4-3) - 1+5×1/5 is 5.

Raw sum of squares (RSS) = 798 + 79 + 461 + 490 = 1828

for the pattern given, we have

position (n) → number of dots

1 → 3

2 → 5

3 → 7

4 → 9

5 → 11

there is a difference of 2 between consecutive dots in the pattern , then

rule is of the form

2n ± ?

the ? is what is required to be added / subtracted to 2n for number of dots

2 × 1 = 2 (+ 1 = 3)

2 × 2 = 4 ( + 1 = 5)

2 × 3 = 6 (+ 1 = 7)

2 × 4 = 8( + 1 = 9)

2 × 5 = 10 (+ 1 = 11)

then 1 requires to be added to 2n to obtain number of dots , so

rule is 2n + 1

position (n) → number of dots

1 → 1 = 1²

There are 6 probability  5 card poker hands with at least 3 Aces that can be dealt from a standard deck of 52 cards.

A standard deck of 52 cards contains 4 Aces, so the maximum number of Aces that can be dealt in a 5 card hand is 3. To determine the number of possible 5 card poker hands with at least 3 Aces, we must first consider the different combinations of 3 Aces in a 5 card hand. There are 6 possible combinations: AAAxx, AAxxA, AxxAA, xAAAX, xAxxA, and xxAAA. This means that there are 6 possible 5 card poker hands with at least 3 Aces that can be dealt from a standard deck of 52 cards. To calculate this, we first counted the number of Aces in the deck and then calculated the number of possible combinations of 3 Aces in a 5 card hand. Finally, we multiplied this number by the number of remaining cards in the deck (48) to get the total number of possible hands.

According to the question,

The multiples of 4 upto 100,

it is an Arithmetic progression sequence with

a = 4 , l = 96 , d = 4

using an = a + (n-1)d where

n --> number of terms in sequence

d ---> common difference between two consecutive terms

a ---> first term

=> 96 = 4 + (n-1)4

Total multiples of 4 upto 100 is 24 .

Now, multiples of 5 upto 100

Q = { 5, 10, 15, ....,100}

Similarly as for above case

a = 5 , d = 5 , l = 100

The point 4 units along the curve (in the direction of increasing t) from P exists as t = ln |L/2 + 1|.

When a particle's position in space is represented as a function of time by a vector-valued function, the arc-length function calculates the particle's travel distance as a function of time.

The length of an arc is the separation of two locations along a segment of a curve. Curve rectification is the process of measuring an irregular arc segment's length by simulating the section as a network of connected line segments. A rectifiable curve can be broken down into a finite number of segments.

(a) Let the given function be r(t) = [tex]e^t[/tex] sin t i + √2 [tex]e^t[/tex] k

To find the arc length of the function, we have:

[tex]& \mathrm{r}^{\prime}(\mathrm{t})=\mathrm{e}^t \\[/tex]

[tex]& \mathrm{r}^{\prime}(t)=(\cos t+\sin t) e^t+(\cos t-\sin t) e^t+\sqrt{2} e^t \\[/tex]

[tex]& \left|r^{\prime}(t)\right|=\sqrt{\left[(\cos t+\sin t) e^t\right]^2+\left[(\cos t-\sin t) e^t\right]^2+\left(\sqrt{2} e^t\right)^2}[/tex]

simplifying the above equation, we get

[tex]& =\sqrt{\left(4 e^{(2 t)}\right)} \\[/tex]

[tex]& =2 \mathrm{e}^t[/tex]

(b) We have the arc length function, L to be the integral from 0 to t, so:

[tex]$& L=\int_0^t 2 e^v \\[/tex]

simplifying the above equation, we get

[tex]& L=2 e^t-2 e^0 \\[/tex]

[tex]& =2 e^t-2 \\[/tex]

[tex]& L=2\left(e^t-1\right) \\[/tex]

simplifying the above equation, we get

[tex]$& L / 2=e^t-1 \\[/tex]

[tex]& L / 2+1=e^t[/tex]

[tex]e^t[/tex] = L / 2+1

t = ln |L/2 + 1|

The complete question is:

A. Find the arc length function for the curve measured from the point P in the direction of increasing t and then reparametrize the curve with respect to arc length starting from P.
