The explicit formula for aₙ is a formula for the nth term of this sequence aₙ = 8n + 17.
What is the explicit formula?
The explicit formulae for L-functions are relations between sums over the complex number zeroes of an L-function and sums over prime powers, introduced by Riemann for the Riemann zeta function.
The formula for the nth term of this sequence is a_n = 8n + 17.
This means that each term in the sequence is equal to 8 multiplied by the position of the term (n) plus 17.
For example, the first term (n = 1) is 25, which can be calculated as 8 * 1 + 17 = 25.
The second term (n = 2) is 33, which can be calculated as 8 * 2 + 17 = 33, and so on.
hence, the explicit formula for aₙ is a formula for the nth term of this sequence is aₙ = 8n + 17.

On solving the provided question, we can say that by unitary method 6 plate cost = $22.69 and 4 more cost = 32.49; total = 32.49+22.69 = $55.18 and cost of each plate = $5.518
What is unitary method ?The unit technique is an approach to problem-solving that involves first determining the value of a single unit, then multiplying that value to determine the required value. The unit method, to put it simply, is used to extract a single unit value from a supplied multiple. For instance, 40 pens would cost 400 rupees, or the price of one pen. The process for doing this may be standardized. a single country. anything that has an identity element. (mathematics, algebra) (Linear algebra, mathematical analysis, mathematics of matrices or operators) Its adjoint and reciprocal are equivalent.
here, by unitary method
6 plate cost = $22.69
and 4 more cost = 32.49

Consider a set-up in which a transmit- ter is transmitting either a 0 or a 1 and the receiver indicates that it received either a 0 or a 1. Denote the events that i = 0, 1 was transmitted by Ti, and the events that i = 0, 1 was indicated as received by Ri. It is possible to have transmission errors. In fact, you are given the following data on accuracy and the frequency of transmitted signals: P[R0 | T0] = 0.99, P[R1 | T1] = 0.98, P[T0] = 0.75. Given that the receiver indicated 1, what is the probability that there was an error in the transmission? What is the overall probability that there was an error in transmission?
To find the probability as per the given question and the information provided, we can compute it as:
a) By using the Bayes formula, we get:
[tex]P[T0|R1] = \frac{P[R1|T0]P[T0]}{P[R1|T0]P[T0] + P[R1|T1]P[T1] }
\\
= \frac{(1 − 0.99) × 0.75}{(1 − 0.99) × 0.75 + 0.98 × 0.25} \\
= \frac{3}{101} ∼= 0.030.[/tex]
b) An error is bound to happen if T0 ∩ R1 or T1 ∩ R0 occur, that is
[tex]P[error] = P[T0 ∩ R1] + P[T1 ∩ R0] \\ = P[R1|T0] × P[T0] + P[R0|T1] × P[T1] \\ = (1 − P[R0|T0]) × P[T0]
+ (1 − P[R1|T1]) × (1 − P[T0]) \\ = 0.01 × 0.75 + 0.02 × 0.25

Fred’s fish tank is shown below how many cubic feet of water will he need to fill in his fish tank l=8.3ft W=11.5ft H=6
Answer:
611.05
Step-by-step explanation:
To find the number of cubic feet of water needed to fill Fred's fish tank, we need to calculate the volume of the tank. The volume of a rectangular prism (such as a fish tank) can be found by multiplying the length, width, and height together. Using the given measurements, the volume of Fred's fish tank would be:
8.3 ft * 11.5 ft * 6 ft = 611.05 cubic ft
So, Fred will need 611.05 cubic ft of water to fill his fish tank.
The table shows values of a function f(x). What is the average rate of change of f(x) over the interval from x = 4 to x = 8? Leave answer as an improper fraction. Show formula and work for credit.
PLEASE HELP!!!!
X 4 5 6 7 8 9 10
f(x) -4 -2 8 10 11 14 18
Answer:
The average rate of change of f(x) over the interval from x = 4 to x = 8 can be calculated as follows:
\frac{f(8)-f(4)}{8-4} = \frac{11-(-4)}{8-4} = \frac{15}{4} = 3 \frac{3}{4}
Therefore, the average rate of change of f(x) over the interval from x = 4 to x = 8 is 3 \frac{3}{4}.
The average rate of change of f(x) over the interval from x = 4 to x = 8 is 3.75.
What is Average Rate of Change?
It is the average amount by which the function changed per unit throughout that time period. It is calculated using the slope of the line linking the interval's ends on the graph of the function.
we have the table,
x 4 5 6 7 8 9 10
f(x) -4 -2 8 10 11 14 18
So, the value of f(4)= -4 and f(8) = 11
Now, average rate of change
= f(8)- f(4) / (8-4)
= 11 - (-4) / 4
= 15 / 4

commercials and the number of movies on which her songs
were played.
number of commercials:
number of movies:
Answer:
number of commercials: 6
Number of movies: 4
Step-by-step explanation:
Let x = the number of commercials
Let y = the number of movies
30x + 110 y = 620
x + y = 10 This can be written y = 10 - x (substitute 10 - x for y)
30x + 110y = 620
30x + 110(10 - x) = 620 Distribute the 110
30x + 1100 - 110x = 620 Combine like terms
-80x + 1100 = 620 Subtract 1100 from both sides
-80x = -480 Divide both sides by -80
x = 6
There are 6 commercials.
Substitute 6 for x
x + y = 10
6 + y = 10 Subtract 6 from both sides
y = 4
There are 4 movies.
Check:
x + y = 10
6 + 4 = 10
10 = 10 checks
30x + 110y = 620
30(6) + 110(4) = 620

Imagine a lidless box with height h and a square base whose sides have length x. The box must have a volume of 117 ft^3. Estimate the value of x that produces the box with a minimum surface area.
The closest value of x that would produce the box with the minimum surface area would be 117 ft.
The volume of a lidless box with height h and a square base with sides of length x is given by V = x^2 * h.
To have a volume of 117 ft^3, we have:
x^2 * h = 117
The surface area of a lidless box is given by:
A = 2x^2 + 4xh
We want to minimize this surface area while still keeping the volume of the box at 117 ft^3. To do this, we need to find an expression for h in terms of x, and then minimize A in terms of x.
From the volume equation, we can solve for h:
h = 117 / x^2
Substituting this expression into the surface area equation, we get:
A = 2x^2 + 4x * (117 / x^2)
= 2x^2 + 466 / x
Now, we can use calculus to find the minimum of A in terms of x.
The derivative of A with respect to x is:
dA/dx = 4x - 466 / x^2
Setting dA/dx equal to zero, we find the critical points:
4x - 466 / x^2 = 0
4x = 466
x = 116.5
We now need to check if x = 116.5 is a local minimum or maximum.
To do this, we need to examine the second derivative of A with respect to x:
d^2A/dx^2 = -932 / x^3
Since the second derivative is negative, this means that A has a local minimum at x = 116.5.
Hence, the value of x that produces the box with a minimum surface area is approximately 116.5 ft.

(a) The displacement (in centimeters) of a particle s moving back and forth along a straight line is given by the equation
s = 2 sin(t) + 3 cos(t),
where t is measured in seconds. (Round your answers to two decimal places.)

(b) Estimate the instantaneous velocity of the particle when
t = 1.
The displacements are 2.84 cm, 2.77 cm, 2.83 cm and 2.83 cm respectively.
Instantaneous velocity of the particle at t =,1 is 0.72 cm/s.
How to calculate displacement and velocity?a. To find the displacement of the particle at various times t, we can simply plug the given value of t into the equation s = 2 sin(t) + 3 cos(t) and evaluate:
[1, 2]: s = 2 sin(1) + 3 cos(1) = 2.84 cm
[1, 1.1]: s = 2 sin(1.1) + 3 cos(1.1) = 2.77 cm
[1, 1.01]: s = 2 sin(1.01) + 3 cos(1.01) = 2.83 cm
[1, 1.001]: s = 2 sin(1.001) + 3 cos(1.001) = 2.83 cm
b. To find the instantaneous velocity of the particle when t = 1, we need to find the derivative of the equation for displacement with respect to time, which will give us the velocity. The derivative is given by:
v(t) = ds/dt = 2 cos(t) - 3 sin(t)
Plugging in t = 1 into this equation, we find:
v(1) = 2 cos(1) - 3 sin(1) = 0.72 cm/s
So, the instantaneous velocity of the particle at t = 1 is approximately 0.72 cm/s.

Use law of sines and show all work please!!
Answer:
below
Step-by-step explanation:
sin x is to 13 as sin 28 is to 21
sinx /13 = sin(28)/21
sinx = 13 * sin (28) /21
sin x = .2906
x = arcsin (.2906) = 16.9°
show that an ordered set has the least upper bound property if and only if it has the greatest lower bound property.
An ordered set has the least upper bound property if and only if it has the greatest lower bound property.
Every nonempty subset A0 of an ordered set A is said to have the least upper bound property and has the lowest upper bound that is constrained above. A fulfills this requirement. Assume B0 is a set of any size with a lower bound. We must demonstrate that it has the largest lower bound. Assume LA is the collection of all the set B0's lower bounds.
∃b0∈B0,∀x∈L,x≤b0.
L is therefore bound above. So it has the lowest upper bound. Let b represent the lower limit of L.
∀x∈L,x≤b.
If ∃b′∈B0,b′≤b, which defies the assertion that b is the lowest upper bound of L. As a result,
b≤y,∀y∈B0.
So, b is the lower bound.
