What is meant by arc length of the function?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|

1) The probability of F2 seed chosen at random will be yellow is the same as asking about the probability of forming a yellow seed in that generation. The answer is 3/4 (75%) because 1/4 = 25% GG is homozygous dominant and the rest 2/4 = 50% Gg are heterozygous.
2) In the F2 generation there are two genotypes that will breed true, which is homozygotic genotypes: GG and gg. But of these two, only one of them is yellow. The answer is 1/3 because from all the yellow seeds that resulted (GG, Gg and gG) only one has the genotype for true breeding.
3) The probability of taking out three seeds in which a least one is yellow can be calculated by subtracting the only probability that doesn't fit the criterion, which is taking out a green seed 3 times: = 1/64.
Then subtract that to 1 = 63/64
4) there are three possible groupings in which the green is taken once and the yellow seeds taken twice. The first possibility (follow the example) is the green being the first to come out, another possibility is being the second and the last possibility is being taken in the third time.

Answer: whats up

Step-by-step explanation:
How many 250g packets of biscuits can be made from 2kg of biscuits
Answer: 250 grams/packet = 8 packets.
Step-by-step explanation:
To find the number of 250g packets of biscuits that can be made from 2kg of biscuits, we need to first convert the weight of the biscuits to the same unit of measurement. Since 1 kilogram is equal to 1000 grams, 2kg of biscuits is equal to 2000 grams. Therefore, the number of 250g packets of biscuits that can be made from 2kg of biscuits is 2000 grams / 250 grams/packet = 8 packets.
Step-by-step explanation:
1 kg = 1000 g
as k stands for "kilo" meaning 1000.
250 g fit therefore 4 times into 1 kg.
and then 2×4 = 8 times into 2×1 = 2 kg.
so, there can be 8 250 g packets made from 2 kg.

1.d = 40; 2 irrational
2.d = 40; 2 rational
3.d = −8; 2 complet
Answer:
first option
Step-by-step explanation:
given a quadratic equation in standard form
ax² + bx + c = 0 ( a ≠ 0 )
then the nature of the roots can be found using the discriminant
Δ = b² - 4ac
• If b² - 4ac > 0 , then the 2 roots are real and irrational
• If b² - 4ac > 0, and a perfect square, then 2 roots are real and rational
• If b² - 4ac = 0 , then 2 roots are real and equal
• If b² - 4ac < 0 , then 2 roots are not real
3x² + 4x - 2 = 0 ← is in standard form
with a = 3, b = 4 and c = - 2 , then
b² - 4ac = 4² - (4 × 3 × - 2) = 16 - (- 24) = 16 + 24 = 40
since b² - 4ac > 0 , then 2 real and irrational roots
Answer:
2. d = 40; 2 rational
Step-by-step explanation:
The discriminant (d) of a quadratic equation [tex]ax^2 + bx + c = 0[/tex] is:
[tex]\boxed{\mathrm{d =} \ b^2 - 4ac}[/tex].
If:
• d > 0, then there are two real solutions
• d = 0, then there is a repeated real solution
• d < 0, then there is no real solution.
In this question, we are given the quadratic equation [tex]3x^2 + 4x - 2 = 0[/tex]. Therefore, the discriminant of the equation is:
b² - 4ac = (4)² - 4(3)(-2)
= 16 - (-24)
= 40
Since the discriminant, 40, is greater than zero, the quadratic equation has 2 rational solutions.
Original TV cost: $700
Current TV cost: $500
Find the percent of decrease
round to the nearest whole percent
Answer: 29%
Step-by-step explanation:
To find the percent of decrease, you need to first calculate the difference between the original cost and the current cost of the TV. You can do this by subtracting the current cost from the original cost: $700 - $500 = $200.
Next, divide the difference by the original cost and multiply by 100% to express the result as a percentage: ($200 / $700) * 100% = 28.57%.
Rounding this result to the nearest whole percent, we get that the percent of decrease is 29%.
Rounded to the nearest whole percent, the answer is 29%.
a closed rectangular box with volume 6 cubic feet is made from two different types of cardboard. the top and bottom are made with a heavy-duty cardboard that costs 30 cents per square foot. the sides are made from a light-weight cardboard that costs 5 cents per square foot. find the dimensions of the box that yield the lowest cost.
As per area of rectangle, the dimensions of the box that yield the lowest cost is (1,1,6)
Area of rectangle:
The standard formula for area of rectangle is calculated as,
A = length x breadth
Given,
A closed rectangular box with volume 6 cubic feet is made from two different types of cardboard. the top and bottom are made with a heavy-duty cardboard that costs 30 cents per square foot. The sides are made from a light-weight cardboard that costs 5 cents per square foot.
Here find the dimensions of the box that yield the lowest cost.
Here let's consider the dimensions of the rectangular box be length l, breadth is b, and height is h.
Now, from the given information, the total cost can be derived as,
=> C=2lb×48+(2bh+2lh)×8
=> C=96lb+16bh+16lh
=> C=16(6lb+bh+lh) -----------------→(1)
Then the given volume is, V = lbh = 6 ---------------→(2) cubic feet.
Then the equation 2,
=> lbh = 6h = 6/lb
And then we have to substitute the value of h in equation 1, we get
=> C(l,b,h)=16(6lb+6/l+6/b)
Now we need to minimize the resulting function of two variables.
Therefore, we need to partially derivative the above function with respect to l,b. And set these equal to zero.
And the for l=0,b is undefined. So we can eliminate l=0.
Here we have to substitute l=1,b=112⇒1 in equation 2, we get
=> lbh=6(1)(1)h=6h=6h=6
Therefore, the critical point is, (1,1,6)

what is an equation of a horizontal line that passes through the point (9, 3)?
y=3 is the equation of a horizontal line that passes through the point (9, 3)
What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
If a line passes through a point (x₁, y₁) and has a slope of m, then the
equation of the line is given by (y-y₁) = m(x-x₁).
Because the question states the line is horizontal, the slope is zero, or m=0.
Plugging the information into the slope equation gives:
(y-(3)) = 0(x-(9)).
y-3= 0
y= 3.

Data Plan A charges a $52 monthly fee for 3GB and then charges $3 for each additional GB. Data Plan B charges a $65 monthly fee for 5GB and then charges an additional $1.75 for each additional GB. At which point is Plan A a better deal than Plan B?
Answer:
Plan A is a better deal than Plan B when you use more than 10.4 GB of data in a month. For any usage lower than that, Plan B would be the cheaper option.
Step-by-step explanation:
To determine at which point Plan A is a better deal than Plan B, we need to compare the total cost of each plan for a given amount of data usage.
The total cost of Plan A for 3GB of data is $52 per month. For every additional GB of data, the cost is $3, so if we use x GB of data beyond the included 3GB, the total cost of Plan A would be $52 + $3x.
The total cost of Plan B for 5GB of data is $65 per month. For every additional GB of data, the cost is $1.75, so if we use x GB of data beyond the included 5GB, the total cost of Plan B would be $65 + $1.75x.
To determine at which point the total cost of Plan A is less than the total cost of Plan B, we can set the two equations equal to each other and solve for x:
$52 + $3x = $65 + $1.75x
$1.25x = $13
x = $13 / $1.25
x = 10.4
Therefore, Plan A is a better deal than Plan B when you use more than 10.4 GB of data in a month. For any usage lower than that, Plan B would be the cheaper option.

Which graph shows a decreasing function in interval (1), an increasing function in interval (2), a constant function in interval (3), and a decreasing function in interval (4)?
The graph that shows the function with the determined behavior is the last graph, circled on the image given at the end of the answer.
How to determine the behavior of the function?The graph of a function is classified as either increasing, decreasing or constant, as follows:
Increasing: as x increases the function increases, that is, the graph moves up.Decreasing: as x increases the function decreases, that is, the graph moves down.Constant: as x increases the function remains constant, that is, the graph stays at the same position.Hence the fourth graph on the image given at the end of the answer is the one with the desired behavior on each interval.
Missing InformationThe graphs are given by the image shown at the end of the answer.

Shannon says that the lines y=-3x-4,y=-(1)/(3)x+6,y=-4x-5, and y=(1)/(4)x-5 could represent the sides of a rectangle. Explain Shannon's error.
The disadvantage is that the coefficients of x in the four equations can only take two values, so if one of every values is m, the alternative will be -1/m.
What is the equation?
A relationship between two terms on either side of an equal sign is depicted by a straightforward equation.
Simple equations also pursue one or a mixture of the four arithmetic computations of addition, simple arithmetic, multiplication, and division.
There are three basic forms of the system of equations: point-slope form, standard form, and slope-intercept form.
So, Shannon's error:
In a rectangle, the neighboring sides are perpendicular to one other, whereas parallel runs between the opposing sides.
The slope of line segments is equal, and the slope, of a perpendicular line to some other line with a slope, m, is -1/m , thus the slopes of the axis of symmetry should be equal, which gives:
The equation should consist of two sets of linear equations with equal slopes: B. Pair y = -x + 6 and y = -x - 5
Therefore, the slopes of the other two lines are -1/-1 = 1 and the equations of the other two lines are y = x - 4 and y = x - 5 respectively.
Therefore, the disadvantage is that the coefficients of x in the four equations can only take two values, so if one of every values is m, the alternative will be -1/m.
