Carlos and Ana were asked to find an explicit formula for the sequence -10,-4,2,8,...−10,−4,2,8,...Minus, 10, comma, minus, 4, comma, 2, comma, 8, comma, point, point, point, where the first term should be f(1)f(1)f, left parenthesis, 1, right parenthesis. Carlos said the formula is f(n)=-10+6nf(n)=−10+6nf, left parenthesis, n, right parenthesis, equals, minus, 10, plus, 6, n. Ana said the formula is f(n)=-10+6(n-1)f(n)=−10+6(n−1)f, left parenthesis, n, right parenthesis, equals, minus, 10, plus, 6, left parenthesis, n, minus, 1, right parenthesis. Which one of them is right?
Answer:
Ana is correct
Step-by-step explanation:
Given
[tex]Sequence:\ -10, -4, 2,8[/tex]
[tex]Carlos; f(n) = -10 + 6n[/tex]
[tex]Ana; f(n) = -10 + 6(n-1)[/tex]
Required
Determine who is right?
To do this, we simply test each sequence.
For Carlos:
When n = 1
[tex]f(1) = -10 + 6 * 1 = -10 + 6 = -4[/tex]
When n = 2
[tex]f(2) = -10 + 6 * 2 = -10 + 12 = 2[/tex]
This is incorrect because the first and second term of the sequence are -10 and -4 not -4 and 2
For Ana:
When n = 1
[tex]f(1) = -10 + 6(1-1) = -10 + 6*0 = -10 + 0 = -10[/tex]
When n = 2
[tex]f(2) = -10 + 6(2-1) = -10 + 6*1 = -10 + 6 = -4[/tex]
When n=3
[tex]f(3) = -10 + 6(3-1) = -10 + 6*2 = -10 + 12 = 2[/tex]
When n = 4
[tex]f(4) = -10 + 6(4-1) = -10 + 6*3 = -10 + 18 = 8[/tex]
This is correct.
Hence, Ana is correct
Answer:
Ana is right

Answer:
The equation y = [tex]-\frac{8}{7}[/tex] x - 7 represents a line perpendicular to the given line
Step-by-step explanation:
The product of the slopes of the perpendicular lines is -1, which means if the slope of one line is m, then the slope of the perpendicular line to it is [tex]\frac{-1}{m}[/tex] (negative reciprocal)
The slope of the equation ax + by = c is [tex]\frac{-a}{b}[/tex], where a, b, c are constantThe slope of the equation y = m x + b is mLet us solve the question
∵ The equation of the given line is 7x - 8y = 16
∴ a = 7 and b = -8
→ Use the rule above to find the slope of it
∵ The slope of the given line = [tex]\frac{-7}{-8}[/tex]
∴ The slope of the given line = [tex]\frac{7}{8}[/tex]
To find the slope of the perpendicular line to it reciprocal the fraction and change its sign
∴ The slope of the perpendicular line = [tex]-\frac{8}{7}[/tex]
→ Look at the answer to find the equation which has this slope
∴ The equation of the perpendicular line is y = [tex]-\frac{8}{7}[/tex] x - 7
A pot holds 16 gallons of soup. A server will empty the pot into one pint containers
How many containers will the server fill?
Answer:
The server will fill 128 containers.
Step-by-step explanation:
1 gallon = 8 pints
In order to find out how many pints is 16 gallons, we need to multiply 16 by 8.
16 x 8 = 128 pints
If each container can only hold one pint of soup, and the pot hold 16 gallons of soup, than the server will fill 128 containers.
Hope this helps! :D

enlist education system found in Nepal
Answer:
Education in Nepal was long based on home-schooling and gurukulas.[citation needed] The first formal school (Durbar School), established by Jung Bahadur Rana in 1853, was intended for the elite. The birth of Nepalese democracy in 1951 opened its classrooms to a more diverse population.[citation needed] Education in Nepal from the primary school to the university level has been modeled from the very inception on the Indian system, which is in turn the legacy of the old British Raj.[1]

Step-by-step explanation:
current ages
Bill is 8
Jenny is 6
and Phil is 4
the dad is 36
9514 1404 393
Answer:
6
Step-by-step explanation:
Let p, b, j, d represent the ages of Phil, Bill, Jenny, and Dad. We are given the relations ...
b = 2p
j = b -2
2(p +b +j) = d
(p+9) +(b+9) +(j+9) = d+9
_____
Solving the last equation for d, we get ...
(p +b +j) +18 = d
Substituting for the sum of p, b, j in the third equation, we have ...
2(d -18) = d
d = 36 . . . . . . . . add 36-d
Substituting for b and j in the third equation, we get ...
2(p +(2p) +(2p-2)) = 36 . . . . . uses b=2p in the 2nd equation
10p -4 = 36 . . . . . . . . . . . . . . . collect terms
p = 40/10 = 4 . . . . . . add 4; divide by 10
b = 2p = 8
j = b -2 = 6
Jenny's current age is 6.
_____
All of the ages are ...
Bill: 8; Jenny: 6; Phil: 4; Dad: 36

To Cool Auto pays commission based on the profit they
make from the vehicle. They pay 21% when profit is less
then $1000, They pay 22,5% when profit is between $1000
and $1200. When they earn a profit over $1200 they pay
23.5%. What formula should replace A, B, and C in the
following plecewise function if x represents the profit from
the sale? Fill in the blanks below,
if x < 81,000
c(x) =
{
if 81,000 < x < $1,200
if x > $1,200
Answer:
The answer is below
Step-by-step explanation:
Let x represent the profit made from sales and c(x) the commission based on sells. If the profit is less then $1000,they 21%, hence:
if x < 1000, c(x) = 0.21x
If the profit is less between $1000 and $1200,they 22.5%, hence:
if 1000 < x < 1200, c(x) = 0.225x
If the profit is greater than $1200,they 23.5%, hence:
if x > 1200, c(x) = 0.235x
Therefore the commission represented as a piecewise function is:
[tex]c(x)=\left \{ {{0.21x\ \ x<1000} \atop {0.225x\ \ 1200<x<1000}} \atop {0.235x\ \ x>1200} \right.[/tex]
what is the nth term of the arith metic sequence 10,16,22,28,......?
Answer:
nth term = 6n + 4 where n = no. of terms.
I hope it will be useful.
Answer:
[tex]a_{n}[/tex] = 6n + 4
Step-by-step explanation:
The n th term of an arithmetic sequence is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 10 and d = a₂ - a₁ = 16 - 10 = 6, then
[tex]a_{n}[/tex] = 10 + 6(n - 1) = 10 + 6n - 6 = 6n + 4

An experiment consists of rolling two fair dice and adding the dots on the two sides facing up. What is the probability that the sun of the dots is 7 or 11
Answer:
4 /9
Step-by-step explanation:
Given that :
Number of faces on a number cube = 6
Sample space for two number faces = 6² = 36
Probability that sum of a roll is 7 or 11:
Probability = number required outcome / Total possible outcomes
Number of Required outcome = number of 7's + number of 11's
Number of 7's = 6
Number of 11's = 2
Total = 8
Total possible outcomes = 6² =36
P(sum of 7 or 11 ) = 8 /36 = 4 /9
3) Graph by making a
table.
y=x
Answer:
See attachment for graph
Step-by-step explanation:
Given
[tex]y = x[/tex]
Required
Plot the graph
First, we need to make a table.
To do this, we assume values for x
When [tex]x = 1[/tex]
[tex]y = x = 1[/tex]
[tex](x_1,y_1) = (1,1)[/tex]
When [tex]x = 2[/tex]
[tex]y = x = 2[/tex]
[tex](x_2,y_2) = (2,2)[/tex]
When [tex]x = 3[/tex]
[tex]y = x = 3[/tex]
[tex](x_3,y_3) = (3,3)[/tex]
When [tex]x = 4[/tex]
[tex]y = x = 4[/tex]
[tex](x_4,y_4) = (4,4)[/tex]
So, the table is:
[tex]x || 1 || 2 || 3 || 4[/tex]
[tex]y || 1 || 2 || 3 || 4[/tex]

Can someone help explain this to me!!! Been stuck on it for a while!!!
Answer:
Step-by-step explanation:
in the formula given. Asin(Bx) the A does mean Amplitude and the Bx is how fast the function repeats... and b/c sin is a function of pi (π) then if we want it to repeat every 2 of x then.. we do need to know the units of X .... but.. here it's just a number.. so we have to add the pi part.. b/c sin repeats every 2pi.... sooo....we are told that it's supposed to have an Amplitude of 3.... just how tall is the highest peak of the sin wave... so that's A = 3 .. and to repeat each time x gets to a multiple of 2.. like 2,4,6, ... ect.
so we have to add the pi part... so that each time x gets to 2 .. the function starts over. :/ this sounds confusing to me.. even as I explain it.. :/
A=3 B=π I'm sure that didn't help much :D ask a question i'll check back

In how many years the simple interest on ₹2000 is less than the simple interest on ₹33000 at 5% by ₹50?
[Irrelevant answers will be reported]
Answer:
0.0322580
Step-by-step explanation:
Simple interest : principal * rate * time
(simple interest on 33000) - (Simple interest on 2000) = 50
Let Time = t
2000 * 0.05 * t = 100t
(33000 * 0.05 * t) = 1650t
1650t - 100t = 50
1550t = 50
t = 50 / 1550
t = 0.0322580

A school club wants to collect at least 500 canned goods for a school food drive. The club has already collected 30 canned goods
Part A
If 10 club members each collect the same number of canned goods, which inequality represents the minimum number of canned goods, n, each club
member must select for the club to meet the goals?
Answer:
The correct answer is 10n ≥ 470.
Step-by-step explanation:
Since, the school club wants to collect at least 500 canned goods, then we know that they don't want to collect any less: they must collet 500 or more canned goods.
They already collected 30 canned goods, therefore we can subtract this quantity from out goal.
500 - 30 = 470
Since there are 10 club members, the number of members multiplied by "n" the minimum amount of canned goods that they can collect, will equal the total amount of canned goods that they need.
Hope this helps! :D
