The
term-to-term rule for a sequence is given as u_n+1=u_n+2
a) Explain in words what this means.
b)Given that u, = -4, list the first five terms of the sequence.
Answer:
- 8, - 6, - 4, - 2, 0
Step-by-step explanation:
the term- to- term rule
[tex]u_{n+1}[/tex] = [tex]u_{n}[/tex] + 2
means that to find a term in the sequence you add 2 to the previous term.
given u₃ = - 4 , then
u₄ = u₃ + 2 = - 4 + 2 = - 2
u₅ = u₄ + 2 = - 2 + 2 = 0
to find the first 2 terms, rearrange the rule as
[tex]u_{n+1}[/tex] = [tex]u_{n}[/tex] + 2 ( subtract 2 from both sides )
[tex]u_{n+1}[/tex] - 2 = [tex]u_{n}[/tex] , that is
[tex]u_{n}[/tex] = [tex]u_{n+1}[/tex] - 2
this allows for a term to be found by subtracting 2 from the next term, so
a₂ = a₃ - 2 = - 4 - 2 = - 6
a₁ = a₂ - 2 = - 6 - 2 = - 8
the first 5 terms are then : - 8, - 6, - 4, - 2, 0

How would you solve questions 25a+b?
Answer:
(a) See attachment.
(b) 12:23
Step-by-step explanation:
Part (a)A bearing is the angle (in degrees) measured clockwise from north.
To mark the position of J on the given map:
Measure an angle of 36° clockwise from K and draw a line.Measure an angle of 284° clockwise from L and draw a line.The location of J is the point of intersection of the two lines.(See attachment).
Part (b)Given:
Distance between K and L = 9600 mSpeed Kendra walks from K to L = 4.5 km/hConvert 9600 meters into kilometers by dividing by 1000:
⇒ 9600 m = 9600 ÷ 1000 = 9.6 km
[tex]\boxed{\sf Speed=\dfrac{Distance}{Time}}[/tex]
Therefore:
[tex]\sf Time=\dfrac{Distance}{Speed}[/tex]
Substitute the given distance and speed into the formula to calculate the time it took Kendra to walk from K to L:
[tex]\implies \sf Time=\dfrac{9.6\;km}{4.5\;km/h}=2.133333...\;hours[/tex]
Convert 2.133333.. into a mixed number:
[tex]\implies \sf 2.133333...=2\frac{2}{15}\;hours[/tex]
To find the number of minutes in 2/15ths of an hour, multiply 2/15 by 60:
[tex]\implies \sf \dfrac{2}{15} \times 60=\dfrac{120}{15}=8\;minutes[/tex]
Therefore, it took Kendra 2 hours and 8 minutes to walk from K to L.
If Kendra left at 10:15:
[tex]\implies \sf 10:15 + 2\;hours = 12:15[/tex]
[tex]\implies \sf 12:15 + 8\;minutes=12:23[/tex]
Therefore, Kendra arrived at L at 12:23.

find the product
(X-2)(x^2x+4)
Answer:
x^3 + 2x^2 + 4x - 8
Step-by-step explanation:
To find the product of (x-2)(x^2+2x+4), we can use the distributive property.
(x-2)(x^2+2x+4) = x(x^2+2x+4) - 2(x^2+2x+4)
= x^3 + 2x^2x - 2x^2 - 4x - 8
= x^3 + 2x^2 + 4x - 8
Answer:
You must apply the distributive principle x3 + 2x2 + 4x - 8 (x-2)(x2+2x+4) = x(x2+2x+4) - 2(x2+2x+4) to obtain the product of (x-2)(x2+2x+4).
So, therefore it is
= x^3 + 2x^2x - 2x^2 - 4x - 8
= x^3 + 2x^2 + 4x - 8

An electrical parts manufacturing company produces resistors of
resistance 700 ohms and they quarantee that the variations will
stay within a range of +5%. Which equation can be used to find
the lowest and highest resistance that can be achieved?
x+700=5
x+700=35
Ix-700=5
x-7001=35
Answer:
d. x-700=35
Step-by-step explanation:
The statement says that the variations will stay within a range of +5%, so the resistance can be increased by 5% of 700 ohms. To find the highest resistance that can be achieved, you can use the formula:
x = 700 + (700 * 5%) = 700 + 35 = 735 ohms
To find the lowest resistance that can be achieved, you can subtract the same percentage (5%) of 700 ohms:
x = 700 - (700 * 5%) = 700 - 35 = 665 ohms
So the lowest and highest resistance that can be achieved are 665 ohms and 735 ohms respectively.

Define Unitary method.The unitary method is a strategy for problem-solving that involves first determining the value of a single unit, then multiplying that value to determine the required value.
What is multiplication?Multiplying in math is the same as adding equal groups. The number of items in the group grows as we multiply. Parts of a multiplication issue include the product, the two factors, and the product. The components in the multiplication problem 6 x 9 = 54 are the numbers 6 and 9, and the result is the number 54.
Let x be the number of seats for the second aircraft.
The first aircraft has x + 64 seats.
The third aircraft has 2x - 152 seats.
The total number of seats for all aircraft is x + (x + 64) + (2x - 152) = 1900.
Therefore, 3x = 2064, so x = 688.
The first aircraft has 688 + 64 = 752 seats.
The third aircraft has 2(688) - 152 = 1224 seats.

If the line through the points (1,2) and (1,a) is parallel to 6x+2y=-2, what is the value of a?
Two lines are parallel if their slopes are equal. To find the slope of the line through the points (1,2) and (1,a), we can use the formula:
(y2 - y1) / (x2 - x1) = (a - 2) / (1 - 1) = a - 2
To find the slope of the line 6x + 2y = -2, we can rewrite it in slope-intercept form (y = mx + b) by isolating y:
2y = -6x - 2
y = -3x - 1
So the slope of this line is -3.
Since the line through the points (1,2) and (1,a) is parallel to 6x + 2y = -2, we know that the slopes must be equal. Therefore:
a - 2 = -3
Solving for a:
a = -1
So the value of a is -1.

What is interest and its types(Simple and compound interest)?
Interest is the cost of borrowing money, where the borrower pays a fee to the lender for the loan. The interest, typically expressed as a percentage, can be either simple or compounded. Simple interest is based on the principal amount of a loan or deposit. In contrast, compound interest is based on the principal amount and the interest that accumulates on it in every period. Simple interest is calculated only on the principal amount of a loan or deposit, so it is easier to determine than compound interest.
The formula for these are
Simple Interest= P×r×n
where:
P=Principal amount
r=Annual interest rate
n=Term of loan, in years
Compound Interest=P×(1+r)^t−P
where:
P=Principal amount
r=Annual interest rate
t=Number of years interest is applied
Here,
Interest rate will be risk percentage + LIBOR
i.e.4.8%
Hence, the interest can be found by using formula for simple interest
Therefore,

Answer: The union of the two intervals is (-∞, ∞) which is the set of all real numbers.
The intersection of the two intervals is [0, 2], which is the set of all numbers that are greater than or equal to 0 and less than or equal to 2.
Step-by-step explanation:
You can visualize this using a number line, with the interval (-∞, 2) represented by the set of numbers to the left of 2 and the interval [0, ∞) represented by the set of numbers greater than or equal to 0. The union of the two intervals would be the entire number line, and the intersection would be the numbers between 0 and 2.
The Karson Transport Company currently has net operating income of 503,000 and pays interest expense of 191,000 . The company plans to borrow 1.15 million on which the firm will pay 11 percent interest. The borrowed money will be used to finance an investment that is expected to increase the firm's net operating income by 408,000 a year.
a) Before the loan is taken out and the investment is made, Karson's times' interest earned ratio is 2.63 times.
b) When the loan and the investment are made, the firm's times interest earned ratio will increase from 2.63 times to 2.87 times.
What is the times' interest earned ratio?The times' interest earned ratio is the ratio that measures the company's ability to meet debt obligations using its net operating income.
The interest earned ratio is computed as the quotient of the net operating income (earnings before interest and taxes) and the interest expense.
Current net operating income = $503,000
Interest expense = $191,000
Times interest earned = 2.63 times ($503,000/$191,000)
Proposed loan = $1.15 million
Interest rate = 11%
Interest amount = $126,500 ($1,150,000 x 11%)
Additional net operating income = $408,000
New net operating income = $911,000 ($503,000 + $408,000)
New interest expense = $317,500 ($191,000 + $126,500)
Adjusted Times interest earned = 2.87 times ($911,000/$317,500)
Thus, if Karson takes the additional loan to finance the investment, its times' interest-earned ratio will increase, showing that it has the ability to settle the debt obligations.

An equation for a rational function with the given characteristics is f(x)=3/2 (x+3)(x-3)/(x+2)(x-2)
What is a function?A relation is a function if it has only One y-value for each x-value.
Since there are vertical asymptotes at X = -2 and X = 2, the denominator will have the terms (x+2) and (x-2)
Since the x intercepts are -3 and 3, the numerator will have the terms (x+3) and (x-3)
So far we have f(X) = a(x+3)(x-3)/(x+2)(x-2)
o find the value of A, we look at the horizontal asymptote. The horizontal asymptote describes what the function looks like when x approaches infinity, therefore a = 3/2
f(x)=3/2 (x+3)(x-3)/(x+2)(x-2)
Hence, an equation for a rational function with the given characteristics is f(x)=3/2 (x+3)(x-3)/(x+2)(x-2)

Answer:
12/13
Step-by-step explanation:
It asks for sinB so lets look at reference angle B. So sin means the ratio between opposite side and hypotenuse. The side opposite to B is 12, and the hypotenuse is 13. Sin can be written as opposite side/hypotenuse. Hence, the answer would be 12/13.
Hope this helped.
If a1=3 and an=-2an-1 then find the whole value of a 5
Answer:
a₅ = 48
Step-by-step explanation:
using the recursive rule [tex]a_{n}[/tex] = - 2[tex]a_{n-1}[/tex] and a₁ = 3 , then
a₂ = - 2a₁ = - 2(3) = - 6
a₃ = - 2a₂ = - 2(- 6) = 12
a₄ = - 2a₃ = - 2(12) = - 24
a₅ = - 2a₄ = - 2(- 24) = 48
devin has a ribbin that is 2 ft long. he cuts it into peices, s shown in the model
The model shows that there are 10 pieces that are each 0. 2 ft long.
How to find the number of pieces ?From the given model, we see that Devin cut the ribbon in equal proportions. The number of proportions can be found by summing the different sections on the ribbon.
This number comes to 10 sections which means that Devin cut the ribbon into 10 pieces.
The length of each of these pieces is:
= Length of entire ribbon / Number of pieces
= 2 / 10
= 0. 2 ft long

Prove the Riemann Hypothesis
Answer:
The Riemann Hypothesis is a conjecture made by mathematician Bernhard Riemann in 1859 that states that all non-trivial zeroes of the Riemann zeta function, which is a complex function that encodes the distribution of prime numbers, lie on the critical line of 1/2. The conjecture is considered one of the most important unsolved problems in mathematics and has yet to be proven or disproven.
There have been many efforts to prove the Riemann Hypothesis over the years, but so far, no one has been able to provide a definitive proof. Many mathematicians have made significant progress in understanding the conjecture and its implications, but a proof remains elusive.
Some of the notable efforts to prove the Riemann Hypothesis include:
In 1859, Riemann himself provided evidence to support the conjecture by showing that the first few non-trivial zeroes lie on the critical line.
In 1911, the mathematician G.H. Hardy proved that an infinite number of non-trivial zeroes lie on the critical line.
In the 1970s, the mathematician A. Selberg proved that an infinite number of non-trivial zeroes lie in the critical strip, which is a slightly wider region around the critical line.
Despite these advances, a proof of the Riemann Hypothesis remains elusive and it continues to be one of the most important unsolved problems in mathematics. Some of the most recent and notable progress on the Riemann Hypothesis has been made by researchers using computational methods such as the Turing method and the Gram-Schmidt orthogonalization method, but the proof is not yet proven.
It's worth mentioning that the Riemann Hypothesis is considered an important problem in mathematics, and solving it could have far-reaching implications for many areas of mathematics and physics, including number theory, cryptography and prime number distribution.
