What are the explicit equation and domain for an arithmetic
sequence with a first term of 5 and a second term of 3?
Given:
First term of an arithmetic sequence = 5
Second term = 3
To find:
The explicit formula for the given arithmetic sequence.
Solution:
We have,
First term: [tex]a_1=5[/tex]
Second term: [tex]a_2=3[/tex]
Common difference is
[tex]d=a_2-a_1[/tex]
[tex]d=3-5[/tex]
[tex]d=-2[/tex]
Now, the explicit formula for an arithmetic sequence is
[tex]a_n=a+(n-1)d[/tex]
where, a is first term and d is common difference.
Putting a=5 and d=-2, we get
[tex]a_n=5+(n-1)(-2)[/tex]
It can also be written as
[tex]a_n=5-2n+2[/tex]
[tex]a_n=7-2n[/tex]
Here, n is an integer greater than or equal to 1.
Domain is the set of input values.
Therefore, the explicit equation is [tex]a_n=5+(n-1)(-2)[/tex] or [tex]a_n=7-2n[/tex] and domain is all interest greater than or equal to 1.
. Critique Reasoning Monica deposits $100 into
a savings account that pays a simple interest
rate of 3.4%. Paul deposits $200 into a savings
account that pays a simple interest rate of 2.2%.
Monica says that she will earn more interest in
one year because her interest rate is higher. Do
you agree? Justify your response.
Answer:
The answer would be no, Monica is wrong.
Step-by-step explanation:
By using the formula for simple interest; Time ( $ x Rate) = Interest
After a year, Monica would have gotten $40.80 in interest,
Paul would have gotten $81.60 in interest.
Because Paul deposited a higher amount of money than Monica, Paul earns more interest.

Eric sells model cars from a booth at a local flea market. He purchases each model car from a distributor for $14 and the flea market charges him a booth fee of $30. Eric sells each model car for $20. How many cars will Eric have to sell to break even?
Answer: 5 cars
Step-by-step explanation:
Breakeven point = Fixed Cost/ Contribution margin
Fixed cost is $30 which is the flea market booth charge
Contribution margin is sales price less variable cost.
The Variable Cost is the amount he is charged by the distributor of $14.
Contribution Margin = 20 - 14
= $6
Breakeven point = 30/6
= 5 cars

Soni has 196 pencils. If she puts equal amounts of pencils into eight boxes, she has four pencils left. How many pencils does she put in each box?
Which strategy could help solve this word problem?
Answer:
Division i think not 100% sure but i think tht
Step-by-step explanation:
Answer:
24 pencils in each box
Step-by-step explanation:
First, you would subtract 4 from 196 which would equal 192. Then, you would divide 192 by 8 since there are eight boxes which equals 24 pencils in each box.
An architect designs a rectangular flower garden such that the width is exactly two-thirds of the length. If 340 feet of antique picket fencing are to be used to enclose
the garden, find the dimensions of the garden
Answer:
The dimensions of the garden is 102 feet by 68 feet
Step-by-step explanation:
Here, we want to get the width and length of the garden
The perimeter is represented by the length of the fencing
From the question;
w = 2l/3
The formula for the perimeter is;
P = 2(l + w)
Thus;
340 = 2(l + 2l/3)
170 = (l + 2l/3)
Multiply through by 3
510 = 3l + 2l
5l = 510
l = 102 feet
w = 2/3 * l
w = 2/3 * 102
w = 68 feet

Step-by-step explanation:
x² + 7x - 18 = 0
the factor must be p and q from the form.of
(x+p)(x+q) = 0
then find the value of p and q by this rules
p + q = 7
p x q = -18
p = 9
q = -2
(x + 9)(x + (-2)) = 0
(x+9)(x-2) = 0
Answer:
c.) [tex](x-2)[/tex]
Step-by-step explanation:
The given expression is written in the form [tex]ac^2+bx+c[/tex]. To factor, find two numbers whose sum is b and whose product is c:
_×_=-18
_+_=7
Use -2 and 7:
-2×9=-18
-2+9=7
Substitute the two numbers for b:
[tex]x^2-2x+9x-18[/tex]
[tex](x^2-2x)+(9x-18)[/tex]
Factor out common terms. The common term in the first parentheses is x and the common term in the second is 9:
[tex]x(\frac{x^2-2x}{x} )+9(\frac{9x-18}{9})\\\\x(x-2)+9(x-2)[/tex]
Cancel out one of the parentheses since they have the same terms and plug the factored numbers in:
[tex](x-2)(x+9)[/tex]
:Done
Check Your Work:
To see if the given factored form is true, simplify it using FOIL:
First, Outside, Inside, Last
[tex](x-2)(x+9)[/tex]
Multiply the first terms:
[tex]x*x=x^2[/tex]
Multiply the terms on the outside:
[tex]x*9=9x\\\\x^2+9x[/tex]
Multiply the inside terms:
[tex]-2*x=-2x\\\\x^2+9x-2x[/tex]
Multiply the last terms:
[tex]-2*9=-18\\\\x^2+9x-2x-18[/tex]
Combine like terms:
[tex]x^2+(9x-2x)-18\\\\x^2+7x-18[/tex]
Therefore, the factored form is true.

It costs $3 for children and $7 for adults to attend a school basketball game. If 5000 people attended the game and the total takings at the door was $25000, determine the number of children and the number of adults that attended the game, using simultaneous elimination.
Answer:
2500 children and 2500 adults
The number of children is 2500 and the number of adults that attended the game is also 2500.
System of equations:Let us consider that, number of children be x and number of adults be y that attend game.
Since, total 5000 people attend the game.
[tex]x+y=5000\\\\x=5000-y..........(1)[/tex]
It costs $3 for children and $7 for adults and the total takings at the door was $25000
[tex]3x+7y=25000 .............(2)[/tex]
Substitute value of x from equation 1 into equation 2.
[tex]3(5000-y)+7y=25000\\\\15000-3y+7y=25000\\\\4y=10000\\\\y=10000/4=2500[/tex]
So that, [tex]x=5000-2500=2500[/tex]
Thus, the number of children is 2500 and the number of adults that attended the game is also 2500.

Answer:
Option A
Step-by-step explanation:
[tex]R = (\frac{V_f-Vi}{V_i} )100[/tex]
where,
[tex]V_f[/tex] is the final value
[tex]V_i[/tex] if the initial value
R is the investors rate of return
so,
[tex]R = (\frac{V_f-Vi}{V_i} )100\\\\R=(\frac{1500-1700}{1700})100 \\\\R=(\frac{-200}{1700})100 \\\\R=-11.8\\[/tex]

True or False? A triangle can have side lengths of 3, 3 , and 6
Answer:
No
Step-by-step explanation:
We can check with the Pythagorean Theorem.
a^2 + b^2 = c^2
a and b are always the smaller sides, the legs
c is the longer side, the hypotenuse
3^2 + 3^2 > 6^2
9 + 9 > 36
18 < 36
18 is not greater than 36, therefore this triangle can not have the side lengths 3, 3, and 6.

A set of floor speakers costs $466. If the extended warranty on the speakers costs 32% of the price of the speakers, how much does the extended warranty cost
Answer: 149.12
Step-by-step explanation:
to find out the extended warranty we do,
466*(32/100)=149.12
The extended warranty cost is $149.12.
What is percentage?Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".
Given that, a set of floor speakers costs $466.
If the extended warranty on the speakers costs 32% of the price of the speakers.
Now, extended price =32% of 466
32/100 ×466
= 0.32×466
= $149.12
Therefore, the extended warranty cost is $149.12.
