(pre-calc) Use Limit Laws to determine the limit of a(n). It is not -∞, so what answer is it and why?
The limit of the function as the variable n tends to minus infinity is -1
Limit of a functionGiven the limit of a function expressed according to the equation;
a(n) = 6n²-n-3n³/3n³+n-1
The value of the function if n tends to minus infinity is expressed as show:
a(n) = 6n²-n-3n³/3n³+n-1
Divide both all the terms by n³
a(n) = 6n²/n³-n/n³-3n³/n³/3n³/n³+n/n³-1/n³
a(n) = 6/n-1/n²-3/(3+1/n²-1/n³)
a(n) = 6/-∞ - 1/(-∞)²-3/(3+1/(-∞)²-1/(-∞)³)
a(n) = -3/3
a(n) = -1
Hence the limit of the function as the variable n tends to minus infinity is -1

2900 dollars is placed in an account with an annual interest rate of 9%. How much will be in the account after 13 years, to the nearest cent?
Answer:
$8,890.83
Step-by-step explanation:
To find the answer we have to use this equation:
[tex]A = P(1 + r)^t[/tex]
A = The total amount
P = The initial amount
R = The interest rate
T = Time
Given in the question:
A = ?
P = 2,900
R = .09
T = 13
Plug it into the equation and solve:
[tex]A = 2900(1 + .09)^1^3\\A = 2900(1.09)^1^3\\A = 2900(3.065804612)\\A = 8890.83[/tex]
Therefore, after 13 years there will be $8,890.83 in the account.

what is 4h-8h in like terms and terms and identify expression
Answer:
4h
Step-by-step explanation:
Expression: 4h-8h=4h
Because both 4h and 8h end in the same variable they can be subtracted when you subtract 4 and 8 you get 4. and You can't forget your variable so you end with 4h
Your expression is a group of terms without an equal sign. 4h and 8h are your terms as well as your answer.
Your expression ends as 4h-8h=4h

pennsylvania sales tax is charged at the rate of 6%. Find the tax and the total price you would pay for an $860 TV
The sales tax will be $51.6, bringing the total cost of $860 TV to $911.6.
What do we mean by sales tax?A sales tax is a tax levied on the sale of certain goods and services and paid to a governing body. Generally, laws allow the seller to collect tax funds from the consumer at the point of purchase.A use tax is a tax on goods or services that is paid directly to a governing body by a consumer. Food, education, and medicines, for example, are frequently exempt from sales and use tax under state law. A value-added tax (VAT) on goods and services is similar to a sales tax. Key differences can be found in the comparison with sales tax.So, to find the sales tax we need to find out the 6% of $860.
= 860/100 × 6= 8.60 × 6= 51.6So, the total price will be 860 + 51.6 = $911.6Therefore, the sales tax will be $51.6 and the total price we would pay for an $860 TV will be $911.6.

At the market, a farmer is selling carrots and potatoes by the pound. The table below shows the amount of each (in pounds) purchased by two customers and the total amount paid (in dollars).
Based on the table on the amount of carrots and potatoes purchased, the cost of each pound of carrots and potatoes are Cost per pound of carrots: $1.50 and per pound of potatoes: $2.00
What is the cost?As you have been given options, you can use the prices in the options to see which price tallies with the total amount that each customer paid.
If you checked all the options, you would find the correct option is the correct option.
The first customer would pay:
= (4 x 1.50) + (6 x 2)
= $18
The second customer:
= (2 x 1.50) + (2 x 9)
= $21
These tally with the amounts paid by the customers so they are the prices of the unit pound of carrots and potatoes.

The formula to determine the period of one swing of a simple pendulum is T=2\pi\sqrt{\frac{L}{g}},T=2π g L , where LL is the length of the string and gg is the acceleration due to gravity. Solve the formula to solve for LL in terms of \pi,π, TT and g.G.
Answer:
L = (T² × g) / 4π²
Step-by-step explanation:
T = 2π√L/g
Where,
L = length of the string
g = acceleration due to gravity
T = 2π√L/g
square both sides of the equation to eliminate the square root
T² = (2π)²√(L/g)²
T² = (2π)²(L/g)
(2π)²
= 2π × 2π
= 4π²
T² = 4π²(L/g)
Multiply both sides by g
T² × g = 4π²(L/g) × g
T² × g = 4π²L
Divide both sides by 4π² to get L
L = (T² × g) / 4π²
