a 1 =49 a i =a i−1 −3 Find the sum of the first 26 terms in the sequence.
By using the concepts of recurrence formula and sum, the sum of the first 26 terms of the sequence is equal to 299.
How to determine the sum of the sequence with the help of recurrence formulas
In this problem we have a recurrence formula of the following form: a₁ = C and aₙ = aₙ₋₁ + k. Then, the sum of first n terms of the sequence is:
s = a₁ + a₂ + a₃ + ... + aₙ₋₁ + aₙ
First, determine the first 26 terms of the series:
a₁ = 49
a₂ = 46
a₃ = 43
a₄ = 40
a₅ = 37
a₆ = 34
a₇ = 31
a₈ = 28
a₉ = 25
a₁₀ = 22
a₁₁ = 19
a₁₂ = 16
a₁₃ = 13
a₁₄ = 10
a₁₅ = 7
a₁₆ = 4
a₁₇ = 1
a₁₈ = - 2
a₁₉ = - 5
a₂₀ = - 8
a₂₁ = - 11
a₂₂ = - 14
a₂₃ = - 17
a₂₄ = - 20
a₂₅ = - 23
a₂₆ = - 26
Second, sum all the terms found in the previous step:
s = 49 + 46 + 43 + 40 + 37 + 34 + 31 + 28 + 25 + 22 + 19 + 16 + 13 + 10 + 7 + 4 + 1 - 2 - 5 - 8 - 11 - 14 - 17 - 20 - 23 - 26
s = 299
The sum of the first 26 terms of the sequence is equal to 299.

Keiko's penny bank is 1/6
full. After she adds 320 pennies, 1/2 it is full. How many pennies can Keiko's bank hold?
Answer: 960
Step-by-step explanation:
Let the number of pennies Keiko's bank hold be x
Now, According to the question,
[tex]\frac{1}{6} \times x+320=\frac{1}{2} \times x[/tex]
⇒ [tex]\frac{1}{6} \times x+320=\frac{x}{2}[/tex]
⇒ [tex]\frac{(x+1960)}{6}=\frac{x}{2}[/tex]
⇒ 2(x + 1920) = 6x
⇒ 2x + 3840 = 6x
⇒ 6x - 2x = 3840
⇒ 4x = 3840
⇒ [tex]x = \frac{3840}{4}[/tex]
⇒ x = 960
Hence, the total number of pennies Keiko's bank hold = 960.

Given the table below, determine the following
Y = -4x+15
(Picture below)
Answer:
y=-1
y=43
x=14
Step-by-step explanation:
So, you have the equation: [tex]y=-4x+15[/tex], and if we know one value we can easily solve for the other using some algebraic manipulation.
Find y when x=4.
For this we know one value, "x", and the other "y" value is unknown. This is actually not to hard if you notice that the equation we're given expresses the value of "y" in terms of "x".
So let's plug in the x-value: [tex]y=-4(4)+15\implies y=-16+15=-1[/tex]
So we get: y=-1, which turns out to be the solution!
Find y when x=-7
This is a similar process, so let's just get straight into it and plug x as -7
[tex]y=-4(-7)+15\\y=28+15\\y=43[/tex]
This is our solution, y=43
Find x when y = -41
So this case is a bit different since we're given the y-value and not the x-value, and as I mentioned the equation represents the value of y in terms of x.
We still do a similar process, except we'll use some more algebraic manipulation, but let's start by plugging in the known value:
[tex]-41=-4x+15[/tex]
Let's move the constant, 15, to the other side by subtracting by 15 to cancel both sides.
[tex]-56 = -4x[/tex]
Now we want to get the x alone, and the only "operation" being done on the x, is that it's being multiplied by the coefficient of -4. To cancel this out we want to divide both sides by -4 to maintain equality & cancel out the coefficient of -4 to one, which is just 1 * x which can be expressed as x as it's implied the coefficient is 1
[tex]14=x[/tex]

The difference between of the cost of the phones in the USA and the UK is $51. 2
What is exchange rate?Exchange rate can be defined as the price of the unit of foreign currency in terms of the home currency.
It is also known as the rate at which a currency is exchanged to another currency
From the information given, we have that;
The cost of a phone in the USA is $1200The cost of a phone in the UK is £920We also have that;
The exchange rate is expressed as;
£1 = $1.36
Now, let's convert the cost from dollars to euros, we have;
If £1 = $1.36
Then, £920 = $x
cross multiply, we have;
x = 920 × 1. 36
x = $1251. 36
Now, let's find the difference between the cost in the USA and UK, we have;
= $1251. 36 - $1200
= $51. 2
Hence, the difference is $51. 2

Vincent made a 2000 deposit into an account on august1 that yields 2% interest compounded annually. How much money will be in that account at the end of 5 years
The money in the account at the end of 5 years is 2208.16
Compound interestThe formula for calculating the compound interest is expressed according to the formula:
Compound interest = P(1+r)^t
Given the following parameters
Principal = 2000
rate = 2 % = 0.02
time = 5 years
Substitute
A = 2000(1+0.02)^5
A = 2000(1.02)^5

a unit received 1,000 rounds of .9mm. they return 450 live rounds. with a brass conversion rate of .009lb, what should be the total weight of the brass returned?
The total weight of the brass returned is 4.04 lb
In this question, we have to find the total conversion of brass return with 450 so multiply the conversion rate by the live rounds return back then we will get our exact answer as follows
A unit received rounds of .9mm = 1000
They return the number of live round units = 450
They return the number of live round units with a brass conversion = .009

lenge You buy 3.16 pounds of oranges, 1.15 pounds of peaches, and 2.24 pounds of apples.
Using the addition, if you buy 3.16 pounds or oranges, 1.15 pounds of peaches and 2.24 pounds of apples , then the total bill is 6.55 pounds
The cost of the oranges = 3.16 pounds
The cost of the peaches = 1.15 pounds
The cost of the apples = 2.24 pounds
Then the total bill = The cost of the oranges + The cost of the peaches + The cost of the apples
