Find an expression for the nth term (tn) in each of the following sequence:
2, 6, 10, 14, 18…
Answer:
The answer is 34
Step-by-step explanation: I just have a big brain
Answer: [tex]t_n = 4n - 2[/tex]
===========================================
Work Shown:
The first term is a = 2 and the common difference is d = 4, since we're adding 4 to each term to get the next term.
[tex]t_n = \text{nth term of arithmetic sequence}\\\\t_n = a+d(n-1)\\\\t_n = 2 + 4(n-1)\\\\t_n = 2 + 4n - 4\\\\t_n = 4n - 2[/tex]
Which is the answer.
--------------------------------
If you were to plug in say n = 3, then we get
[tex]t_n = 4n - 2\\\\t_3 = 4(3) - 2\\\\t_3 = 12 - 2\\\\t_3 = 10[/tex]
showing that 10 is the third term, which matches with what the original sequence shows. I'll let you check the other values of n to fully confirm the answer.

The expression - 370 + 15z represents a submarine that began at a depth of 370 feet below sea leve
and ascended at a rate of 15 feet per minute. What was the depth of the submarine after 5 minutes?
Answer:
The depth of the submarine was 295 feet
Step-by-step explanation:
Function Modeling
The following expression models the depth of a submarine that began at -370 m and ascended at 15 ft/minute:
d = -370 + 15z
Where z is the time in minutes.
We are required to find the depth of the submarine at t=5 minutes. Substituting t=5 into the function model:
d = -370 + 15(5)
d = -370 + 75
d = -295 feet
The depth of the submarine was 295 feet

Answer:
Not a function
Step-by-step explanation:
This is not a function because every x value has more than one y value. Think about it this way. If you have a person and you are telling them to go to three different places at once, they can't. That means this isn't a function. Hope this helps!

Lili runs a small day care business, caring for 3 children.
• She earns $150 during regular work hours.
• She charges $0.50 for each minute parents are late.
The situation is represented by the equation below, where t is the total
dollar amount Lili earns each day and m is the total number of minutes
parents are late.
t=150 +0.5m
Which of the following solutions shows an amount of money Lili can
reasonably expect to earn each day?
Answer:
$150
Step-by-step explanation:
[tex]t=150 + 0.5m\\t=150+0.5*0\\t=150[/tex]
This is as we don't know how often the parents are late, nor if they are late. So we assume that the parents are never late.

The science center has 200 people in attendance on Monday. The center expects Saturday’s attendance to be 140 percent of Monday’s attendance. Natasha is trying to figure out how many people will be in attendance. Her work is shown below. StartFraction part Over whole EndFraction = StartFraction 140 Over 100 EndFraction StartFraction 140 divided by 2 Over 100 times 2 EndFraction = StartFraction question mark Over 200 EndFraction 140 divided by 2 = 70 70 people will be in attendance. What mistake did Natasha make? Natasha should have multiplied 140 by 2. Natasha should have divided 100 by 2. Natasha should have added 140 and 200. Natasha should have multiplied 140 and 200.

PLEASE HELP 4. The Buff City Soaps in Arlington is counting how many soaps and bath bombs they sell in a given day. In total, they sold 33 bath products. The number of soaps they sold was one more than three times the number of bath bombs. WRITE THE SYSTEM OF EQUATIONS.
Answer:
33 = x + (3x + 1)
x = bath bombs
So 3x is three times as many bath bombs, then the plus one makes it so that the soaps sold is more than three times the amount of bath bombs sold
