The recursive sequence are: 17, 13, 9, 5, 1.
The recursive rule for the sequence [tex]a_{n}[/tex] = 17 - 4n is
[tex]a_{1[/tex] = 17
[tex]a_{n}[/tex] = [tex]a_{n-1}[/tex] - 4 for n ≥ 2
Using this rule, we can find the first few terms of the sequence
[tex]a_{1[/tex] = 17
[tex]a_{2}[/tex] = [tex]a_{1[/tex] - 4 = 17 - 4 = 13
[tex]a_{3}[/tex] = [tex]a_{2}[/tex] - 4 = 13 - 4 = 9
[tex]a_{4}[/tex] = [tex]a_{3}[/tex] - 4 = 9 - 4 = 5
[tex]a_{5}[/tex] = [tex]a_{4}[/tex] - 4 = 5 - 4 = 1
and so on.

Use the given acceleration function and initial conditions to find the velocity vector v(t), and position vector r(t). Then find the position at time t = 9. a(t) = −cos ti − sin tj v(0) = j + k, r(0) = i v(t) = r(t) = r(9) =
find the position at time t = 9. a(t) = −cos ti − sin tj v(0) = j + k, r(0) = i v(t) = r(t) = r(9) = This gives you the position vector r(9) as a function of sin(9) and cos(9).
To find the velocity vector v(t) and position vector r(t), we need to integrate the given acceleration function a(t) and apply the initial conditions. Here's a step-by-step explanation:
1. Given acceleration function: a(t) = -cos(t)i - sin(t)j
2. Integrate a(t) with respect to t to find v(t):
v(t) = ∫(-cos(t)i - sin(t)j) dt = (sin(t)i + cos(t)j) + C, where C is a constant vector.
3. Apply initial condition v(0) = j + k:
v(0) = sin(0)i + cos(0)j + C = j + k
C = -i + j + k
4. The velocity function is: v(t) = sin(t)i + cos(t)j - i + j + k
Now let's find the position vector r(t):
5. Integrate v(t) with respect to t to find r(t):
r(t) = ∫(sin(t)i + cos(t)j - i + j + k) dt = (-cos(t)i + sin(t)j + t(k) + D, where D is another constant vector.
6. Apply initial condition r(0) = i:
r(0) = -cos(0)i + sin(0)j + 0(k) + D = i
D = i
7. The position function is: r(t) = -cos(t)i + sin(t)j + tk + i
Finally, let's find the position at time t = 9:
8. r(9) = -cos(9)i + sin(9)j + 9k + i
This gives you the position vector r(9) as a function of sin(9) and cos(9).

Use the appropriate compound interest formula to find the amount that will be in each account, given the stated coins, $47.000 invested at 5% annual interest for 5 years compounded (a) annually: (b) semiannually
a)The amount in the account after 5 years, compounded annually, will be approximately $60,625.06.
b) The amount in the account after 5 years, compounded semiannually, will be approximately $61,588.88.
The amount in the account after 5 years can be calculated using the compound interest formula. For an initial investment of $47,000 at an annual interest rate of 5%, compounded annually or semiannually, the amount in the account will be different.
(a) For compounding annually:
The compound interest formula is given by:
A = P(1 + r/n)^(nt)
where:
A = the amount after time t
P = principal amount (initial investment) = $47,000
r = annual interest rate = 5% or 0.05 (as a decimal)
n = number of times interest is compounded per year = 1 (since it is compounded annually)
t = time period = 5 years
Plugging in the given values, we get:
A = 47000(1 + 0.05/1)^(1*5)
A = 47000(1.05)^5
A ≈ $60,625.06
So, the amount in the account after 5 years, compounded annually, will be approximately $60,625.06.
(b) For compounding semiannually:
The only difference from the above calculation is the value of 'n', which is the number of times interest is compounded per year. In this case, 'n' will be 2, as interest is compounded semiannually (twice a year).
Plugging in the given values, we get:
A = 47000(1 + 0.05/2)^(2*5)
A = 47000(1.025)^10
A ≈ $61,588.88
So, the amount in the account after 5 years, compounded semiannually, will be approximately $61,588.88.

Among 130 pupils, 30 liked both biscuits and chocolates, 10 liked neither and twice as many as liked biscuits liked chocolates.
I) How pupils liked: chocolates, biscuits and exactly one of the two.
The number of pupils who liked both biscuits and chocolates is 30.
The number of pupils who liked neither biscuits nor chocolates is 10.
Let's assume that the number of pupils who liked only biscuits is x, and the number of pupils who liked only chocolates is y.
According to the problem, twice as many pupils liked chocolates as those who liked biscuits. Mathematically, we can write this as:
y = 2x
Now, let's find the total number of pupils who liked at least one of the two:
Total = P(Biscuits) + P(Chocolates) - P(Biscuits and Chocolates)
Total = x + y + 30
Total = x + 2x + 30
Total = 3x + 30
We know that the total number of pupils is 130, and the number of pupils who liked neither is 10. Therefore,
Total = P(All pupils) - P(Neither)
130 = x + y + 30 + 10
130 = x + y + 40
130 - 40 = x + y
90 = x + y
We can now solve these two equations to get the values of x and y:
3x + 30 = 90
3x = 60
x = 20
y = 2x = 40
Therefore, 20 pupils liked only biscuits, 40 pupils liked only chocolates, and 30 pupils liked both biscuits and chocolates. And, 40 pupils liked exactly one of the two.

The function models the amount of money a new business has made over x months. Negative values represent debt. Over what interval is the amount increasing?
If the line has a positive slope, it means that the amount is increasing, and if it has a negative slope, it means that the amount is decreasing.
Based on the given information, the function models the amount of money a new business has made over x months. Therefore, we can assume that the function is a linear function, and its graph is a straight line.
Given that negative values represent debt, we can assume that the slope of the line is positive over the interval where the function takes positive values. Therefore, the interval over which the amount is increasing is from zero to infinity, which means that the business is making money and not in debt.
It's essential to note that if the function has a negative slope over any interval, then the amount is decreasing, and the business is losing money. However, we cannot determine this information from the given function's information.

A study is designed to test the hypotheses h0: m $ 26 versus ha: m , 26. a random sample of 50 units was selected from a specified population, and the measurements were summarized to y 5 25.9 and s 5 7.6. a. with a 5 .05, is there substantial evidence that the population mean is less than 26
The p-value for a t-score of -0.92 is approximately 0.18 and since it is greater than the significant level, the null hypothesis is rejected.
The first step in testing this hypothesis is to calculate the test statistic, which in this case is a t-score. The formula for the t-score is (y - mu) / (s / sqrt(n)), where y is the sample mean, mu is the hypothesized population mean, s is the sample standard deviation, and n is the sample size.
In this case, the sample mean is 25.9, the hypothesized population mean is 26, the sample standard deviation is 7.6, and the sample size is 50. Plugging these values into the formula, we get a t-score of -0.92.
Next, we need to find the p-value associated with this t-score. We can use a t-table or a calculator to do this. Using a t-table with 49 degrees of freedom (since we have a sample size of 50 and one parameter estimated from the sample), we find that the p-value for a t-score of -0.92 is approximately 0.18.
Since the p-value is greater than the significance level of 0.05, we fail to reject the null hypothesis. In other words, we do not have substantial evidence to conclude that the population mean is less than 26. However, it is important to note that the sample mean is slightly below the hypothesized population mean, and the p-value is relatively close to the significance level. Therefore, it may be worthwhile to conduct additional studies with larger sample sizes or different populations to further investigate this question.

What three-dimensional figure is formed when the triangle shown is rotated around the dashed line?
A. cone
B. cylinder
C. double cone
D. hemisphere
Answer: C
Step-by-step explanation: after rotating, if you split it in half horizontally, you have two cones
The three-dimensional figure formed when the triangle is rotated around the dashed line through B and C is a cone.
What is a cone?A cone is a three-dimensional geometric form with a flat base and a smooth, tapering apex or vertex. A cone is made up of a collection of line segments, half-lines, or lines that link the base's points to the apex, which is a common point on a plane that does not include the base.
When we rotate a two-dimensional shape around an axis, we create a three-dimensional solid. This process is known as "revolution" or "rotational symmetry".
In this particular case, we have a triangle that can be rotated around the line segment that connects points B and C. If we were to rotate the triangle around this axis, we would create a three-dimensional solid. To figure out what kind of solid this is, we can think about the cross-sections that would be created if we were to slice through the solid perpendicular to the axis of rotation.
If we were to slice through the solid perpendicular to the axis of rotation, we would get a circle. This means that the solid created by rotating the triangle is a cylinder.

Mr. Vara is designing post caps in the shape of a square pyramid for his fence. The caps are solid wood and have a volume of 94.5 cubic centimeters. To calculate the dimensions of the pyramid, we need to use the formula for the volume of a square pyramid, which is V = (1/3)bh, where b is the area of the base and h is the height of the pyramid.
Since the caps are square pyramids, the base is a square. Let's call the side length of the base s. Then the area of the base is s². We can rearrange the formula for volume to get h = (3V)/b. Plugging in the given volume of 94.5 cubic centimeters, we get:
h = (3 x 94.5) / s²
h = 283.5 / s²
We still need to find the side length s. We can use the fact that the volume of the pyramid is also equal to [tex](1/3)s^{2h[/tex]. Plugging in the volume and height from above, we get:
94.5 = (1/3)s²(283.5 / s²)
94.5 = 94.5
This equation simplifies to 1 = 1, which doesn't give us any information about s. However, we can make an assumption about the dimensions of the pyramid. Let's say that the height h is equal to the side length s. Then we can solve for s using the volume formula:

4. Question: How can an antiderivative of a velocity function be used to find displacement of the body? Question: If velocity is negative, how does this impact the problem of finding displacement? 5.
If velocity is negative,The body is moving backwards instead of forwards, so the displacement will be measured as a negative value.
An antiderivative of a velocity function can be used to find displacement of the body by integrating the velocity function over a given time interval. The result of this integration will give the total displacement of the body over that time interval.
If the velocity is negative, it means that the body is moving in the opposite direction to the positive direction of the coordinate system. This has an impact on the problem of finding displacement because the displacement will also be negative. In other words, the body is moving backwards instead of forwards, so the displacement will be measured as a negative value.

In a recent report, Joe's, a Memphis-style barbecue chain, states that 11% of its customers order for delivery. A random sample of 6 Joe's customers is chosen. Find the probability that at most 1 of them order for delivery. " Do not round your intermediate computations, and round your answer to three decimal places.
P(X ≤ 1) = P(X = 0) + P(X = 1) ≈ 0.901
So the probability that at most 1 customer in the sample orders for delivery is approximately 0.901, rounded to three decimal places.
To solve this problem, we can use the binomial distribution since we have a fixed number of trials (6) and each trial can result in one of two outcomes (ordering for delivery or not).
Let X be the number of customers in the sample who order for delivery. Then X follows a binomial distribution with parameters n = 6 and p = 0.11 (the probability of ordering for delivery).
We want to find the probability that at most 1 customer orders for delivery. This can be written as:
P(X ≤ 1) = P(X = 0) + P(X = 1)
To calculate these probabilities, we can use the binomial probability formula:
P(X = k) = (n choose k) *[tex]p^k[/tex]*[tex](1 - p)^(n - k)[/tex]
where (n choose k) is the binomial coefficient, which represents the number of ways to choose k items from a set of n distinct items.
Using this formula, we can calculate:
P(X = 0) = (6 choose 0) * 0.11^0 * [tex]0.89^6[/tex] ≈ 0.530
P(X = 1) = (6 choose 1) * 0.11^1 * 0.89^5 ≈ 0.371

The target to the right is in your backyard. What is the probability of hitting the bulls eye (center circle) when you shoot an arrow? The radius of the bulls eye is 2ft and the radius of the target is 6ft. (Use 3. 14 for pi)
The probability of hitting the bulls eye (center circle) when we shoot an arrow with radius of the bulls eye is 2ft and the radius of the target is 6ft is 11.1%.
Assuming that we are shooting randomly at the target and the arrow can land anywhere within the target area, the probability of hitting the bull's eye (center circle) can be calculated as the ratio of the area of the bull's eye to the area of the entire target.
The area of the bull's eye can be calculated as follows:
Area of bull's eye = π x (radius of bull's eye)²
Area of bull's eye = 3.14 x 2²
Area of bull's eye = 12.56 square feet
The area of the entire target can be calculated as follows:
Area of target = π x (radius of target)²
Area of target = 3.14 x 6²
Area of target = 113.04 square feet
Therefore, the probability of hitting the bull's eye can be calculated as:
Probability of hitting bull's eye = Area of bull's eye / Area of target
Probability of hitting bulls eye = 12.56 / 113.04
Probability of hitting bulls eye = 0.111 or approximately 11.1%
So, the probability of hitting the bull's eye (center circle) when we shoot an arrow randomly at the target is approximately 11.1%.
