What is the nth term rule of the quadratic sequence below? 7, 14, 23, 34, 47, 62, 79 Please could someone help me and write a step by step explanation? Thanks :D
Step-by-step explanation:
The first differences are 7,9,11,13,15,17 and the second differences are 2.
This means that the first term of the sequence is n^2.
Subtracting n^2 from the sequence gives 6,10,14,18,22,26, which has nth term of 4n + 2.
So putting these together gives a nth term of the quadratic sequence of n^2 + 4n + 2.
Hope it helped and tell me if I went wrong :)

A sprinkler shoots out a jet of water 6 m as it spins around. What is the area of lawn that can be watered by the sprinkler?.
Answer:
113.097 square meters
Step-by-step explanation:
First, let's take a moment to visualize the information in this problem. Assuming the sprinkler has full range of motion, this would mean the area covered by the water would form a circular shape, with the sprinkler as the center.
Using this information, we also know that the 6 m of water sprayed by the sprinkler is equal to the radius of the circle. In order to find the area of the shape, we will use the formula for the area of a circle:
A = pi(r^2)
Filling in our known radius, we have:
A = pi(6^2) = pi(36) = 113.097 square meters

cost of goods manufactured for branson books for the year was $860,000. beginning work-in-process inventory was $40,000. ending work-in-process was $60,000. if the beginning finished goods inventory was $400,000 and the ending finished goods inventory was $990,000 what was the cost of goods sold for the year
The cost of goods sold for the year can be calculated by adding the beginning finished goods inventory to the cost of goods manufactured, and then subtracting the ending finished goods inventory.
Therefore, the cost of goods sold for the year for Branson Books is: $400,000 (beginning finished goods inventory) + $860,000 (cost of goods manufactured) - $990,000 (ending finished goods inventory) = $270,000.
This means that the total cost of goods sold for the year was $270,000. Cost of goods manufactured represents the total cost incurred by the company to manufacture the goods during the year. Beginning work-in-process inventory represents the cost of goods that were partially completed at the beginning of the year, while ending work-in-process inventory represents the cost of goods that were partially completed at the end of the year.
By subtracting the beginning work-in-process inventory from the total cost of goods manufactured and adding the ending work-in-process inventory, the cost of goods completed during the year can be calculated. This cost, when added to the beginning finished goods inventory, represents the total cost of goods available for sale. By subtracting the ending finished goods inventory, the cost of goods sold can be calculated. In this case, we have calculated the cost of goods sold for Branson Books to be $270,000.

The strength factor of the evidence you just got that you picked the special box is 4.
Given:
There are four boxes that look the same. in one box (the special one), half of the marbles are blue. but only 1/8 of the marbles in the other boxes are blue.
Hypothesis = The box the blue marble was picked from is the special box.
Prior confidence = 1:3 (ratio of special boxes to non special boxes )
Now P(B | S) = 1/2 (given that a box is selected from the special box, there is 1/2 chance that it is blue)
And P(B | NS) = 1/8 (given that a box is selected from a non-special box, there is 1/8 chance that it is blue)
According to bayes factor ,we get:
P(B | S)/P(B | NS) = (1/2)/(1/8) = 4
Thus, 4.

Solve for x: x − 2 > 2x + 12. (1 point) x > 14 x < 14 x > −14 x < −14
Answer:
Step-by-step explanation:
x<-14
Answer:
x < -14 is correct.
Step-by-step explanation:
Here is the work:
x - 2 > 2x + 12
I will start by getting rid of the 2x , so subtract 2x from both sides.
-x -2 > 12
Add 2 to both sides.
-x > 14.
Multiply by negative 1 on both sides because -1 times -1 is 1, so you get 1x (x).
When multiplying by a negative, you switch the sign around.
x < -14.
What is the focus of the parabola given by the equation y= x^2 - 2x - 3
Answer:
Step-by-step explanation:
We can best determine this by putting the quadratic into work (vertex) form by completing the square. Move the -3 over to the other side to get
x^2 - 2x = 3. Now take half the linear term, square it, and add it to both sides. Our linear term is 2. Half of 2 is 1, and 1 squared is 1, so we add that to both sides:
x^2 - 2x + 1 = 3 + 1 and do some simplifying to both sides. The left side is a perfect square binomial:
(x - 1)^2 = 4
Move the 4 back over to get the vertex form of the quadratic:
y = (x-1)^2 - 4
The "a" value is a 1. Since p is found using a, and the coordinates of the focal point are (h, k + p), we need the vertex and the value of a. Now we have both. The value of p is found in:
\(p=\frac{1}{4lal}\) (those are absolute value symbols), hence, our p value is 1/4.
The coordinates of the focal point are (1, -4 + 1/4) or (1, -15/4)

The _____ ______ is a statement we are trying to find evidence to support. Drag your answer(s) to the correct position
A hypothesis is a statement regarding a characteristic of one or more populations. The null hypothesis is a statement of no change, no effect, or no difference. The alternative hypothesis is a statement we are trying to find evidence to support.
Generally, the null hypothesis expresses that there is no change, no difference, no effect, and in another way, no relationship between the independent and dependent variables. Because we are hypothesizing that nothing is happening, then it is called the null hypothesis.
The null and alternative hypothesis are two conflicting claims which researchers weigh evidence for and against using a statistical test. Null hypothesis (H0) means there is no effect in the population. Meanwhile, alternative hypothesis (Ha or H1) means there is an effect in the population.

The answer is B
Step-by-step explanation:
what is the slope of a line perpendicular to the line whose equation is x+4=28
The slope of a line perpendicular to the line is -4
The equation is x -4y = 28
The equation for the line is
y = mx + c
where m = slope
c = y-intercept
Here the equation is x - 4y = 28
4y = x - 28
y = x/4 - 7
So the slope of this line is 1/4
Now we have to find the slope of the line perpendicular to that line.
We know that,
m1 × m2 = -1
1/4 × m2 = -1
m2 = -4
Therefore the slope of the line perpendicular to the line is -4.

Answer:
A ≈ 34.91 m²
Step-by-step explanation:
the area (A) of the sector is calculated as
A = area of circle × fraction of circle
= πr² × \(\frac{40}{360}\) ( r is the radius )
= π × 10² × \(\frac{1}{9}\)
= \(\frac{100\pi }{9}\)
≈ 34.91 m² ( to 2 decimal places )
Answer:
34.88m²
(round 35m²)
Step-by-step explanation:
a round angle, that of the circle, is 360°, here we have a portion of 40°, we divide 360° by 40° and we have the percentage with respect to the circle
360° : 40° = 9
we now know that the wedge is 1/9 of the circlefind the area of the whole circle having the radius (10m)Area of Circle Formulas · Area = π × r2, where 'r' is the radius
Area = π × r2
Area = π × 10²
Area = π × 100
Area = 3.14 × 100
Area = 314 m²
now we divide by 9 and we have the area of the wedge314 : 9 = 34.88m² (round 35m²)
1. Use Horner's algorithm to find p(4), where p(z) = 3z^2 – 7z^4 – 5z^3+z^2 -- 8z +2. 2. (Continuation) For the polynomial of preceding problem, find its expansion in a Taylor series about the point z0 = 4. 3. (Continuation) For the polynomial of Problem 3.5.1 (above), start Newton's method at the point z0 = 4. What is z1?
Evaluating p(4) using Horner's algorithm:
1. To use Horner's algorithm, we write the polynomial in nested form as follows:
p(z) = ((3z - 7)z - 5)z^2 + (z - 8)z + 2
Now, we can evaluate p(4) by starting from the inside and working our way out:
p(4) = ((3(4) - 7)4 - 5)4^2 + (4 - 8)4 + 2
= (5)4^2 - 4 + 2
= 78
Therefore, p(4) = 78.
2. Finding the Taylor series expansion of p(z) about z0 = 4:
To find the Taylor series expansion of p(z) about z0 = 4, we need to compute the derivatives of p(z) at z0 = 4. First, we compute p'(z) = 6z^2 - 28z^3 - 10z^2 + 2z - 8, then p''(z) = 12z - 84z^2 - 20z + 2, p'''(z) = 12 - 168z - 20, and so on.
Using these derivatives, we can write the Taylor series expansion of p(z) about z0 = 4 as follows:
p(z) = p(4) + p'(4)(z - 4) + p''(4)(z - 4)^2/2! + p'''(4)(z - 4)^3/3! + ...
Substituting in the values we computed, we get:
p(z) = 78 + 10(z - 4) - 41(z - 4)^2/2! - 14(z - 4)^3/3! + ...
Therefore, the Taylor series expansion of p(z) about z0 = 4 is:
p(z) = 78 + 10(z - 4) - 20.5(z - 4)^2 - 2.333(z - 4)^3 + ...
3. Using Newton's method to find a root of p(z):
To use Newton's method to find a root of p(z), we start with an initial guess z0 = 4 and iterate the formula z1 = z0 - p(z0)/p'(z0) until we reach a desired level of accuracy.
4. We already computed p'(z) in part 2, so we can use the formula to compute z1 as follows:
z1 = z0 - p(z0)/p'(z0)
= 4 - (78 + 10(4) - 20.5(4 - 4)^2 - 2.333(4 - 4)^3)/[6(4)^2 - 28(4)^3 - 10(4)^2 + 2(4) - 8]
= 3.9167
We can continue to iterate using this formula to get better approximations for the root of p(z).
Horner's algorithm is a fast and efficient way to evaluate a polynomial at a particular point. It involves using the distributive property of multiplication to rewrite a polynomial in a nested form, then evaluating the polynomial from the inside out.
In this problem, we will use Horner's algorithm to evaluate p(4) for a given polynomial, find its Taylor series expansion about the point z0 = 4, and then use Newton's method to find an approximation for a root of the polynomial.

∫x216−x2−−−−−−√ dx= 8arcsin(x/4)-4sin(2arcsinx/4) functionsequation editor c (your final answer should be in terms of only x .) note: you can earn partial credit on this problem.
The final answer is 8arcsin(x/4) - 4sin(2arcsin(x/4)) + C, where C represents the constant of integration. The expression is given in terms of x only.
To evaluate the given integral, we can use trigonometric substitution. Let's substitute x = 4sinθ, which allows us to rewrite the integrand in terms of θ. The differential becomes dx = 4cosθ dθ.
Using this substitution, the integral transforms into ∫(4sinθ)²√(16-(4sinθ)²)(4cosθ) dθ. Simplifying this expression yields 16∫sin²θ√(1-cos²θ)cosθ dθ.
We can apply the double-angle identity sin²θ = (1-cos2θ)/2 to simplify further. This results in 8∫(1-cos2θ)√(1-cos²θ)cosθ dθ.
Next, we can apply the trigonometric identity sin(2θ) = 2sinθcosθ to obtain 8∫(sinθ-sin³θ) dθ.
Finally, integrating term by term and substituting back x = 4sinθ, we arrive at the final answer of 8arcsin(x/4) - 4sin(2arcsin(x/4)) + C. This expression represents the antiderivative of the given function in terms of x only, where C represents the constant of integration.
