Write down in terms of n,an expression for the Nth term of the following sequences.
A) 2,5,8,11,14
B) 9,11,13,15,17
Answer:
see explanation
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
A
There is a common difference d between consecutive terms , that is
d = 5 - 2 = 8 - 5 = 11 - 8 = 14 - 11 = 3
Thus the sequence is arithmetic with a₁ = 2 and d = 3, then
[tex]a_{n}[/tex] = 2 + 3(n - 1) = 2 + 3n - 3 = 3n - 1
[tex]a_{n}[/tex] = 3n - 1
B
There is a common difference d between consecutive terms , that is
d = 11 - 9 = 13 - 11 = 15 - 13 = 17 - 15 = 2
Thus the sequence is arithmetic with a₁ = 9 and d = 2 , then
[tex]a_{n}[/tex] = 9 + 2(n - 1) = 9 + 2n - 2 = 2n + 7
[tex]a_{n}[/tex] = 2n + 7
Answer:
so for question a the ans is 3n-1
for question b the ans is 2n+7
Step-by-step explanation:
Question Ausing the formula for arithmetic progressikn(a.p) a +(n-1)d, u use this formula because it has a common differnce
a=2, where a is first term or t1
d=t2-t1=5-2=3m where d is common difference
replace the values in the formula
2+(n-1)3
2+3n-3
3n-3+2
3n-1, this is the formula for the nth term
it will be 3n -1
if u try it
3(1)-1=2
3(2)-1=5
3(3)-1=8
3(4)-1=11
3(5)-1=14
Question B
using the formula for a.p, a+(n-1)d
a=9, because it is the first term
d=t2-t1=11-9=2
replace the values in the formula
9+(n-1)2
9+2n-2
2n+9-2
2n +7,this is the formula for the7th term
if u try it
2(1)+7=9
2(2)+7=11
2(3)+7=13
2(4)+7=15
2(5)+7=17

Nina delivers newspapers. In the first week, she delivers 8 papers. In the second week, she delivers 32 papers. Which equation can Nina use to find how many times as many papers she delivered the second week as the first week?
Answer:
a) The equation can Nina use to find how many times as many papers she delivered the second week as the first week is given as:
8x = 32
b) Nina delivered 4 times as many papers the second week as the first week
Step-by-step explanation:
From the question, we are told that:
Nina delivers newspapers.
In the first week, she delivers 8 papers.
In the second week, she delivers 32 papers.
Let x represent the number of times
The equation can Nina use to find how many times as many papers she delivered the second week as the first week is given as:
8paper × x = 32 papers
8x = 32
Solving for x
8x = 32
x = 32/8
x = 4 times
Therefore, Nina delivered 4 times as many papers the second week as the first week

X^2+12=40 what number must you add to complete the square?
Answer:
Step-by-step explanation:
1) If you really meant X^2+12=40, then this simplifies to x^2 = 28, and therefore x = ±√28, or x = ±2√7.
2) If you meant X^2+12x=40:
a) Take half of the coefficient of x: that would be (1/2)(12), or 6.
b) Square this result, obtaining: 6² = 36
c) Add this 36 to x^2 + 12x + 40, and then subtract it: We get:
x² + 12x + 36 - 36 = 40, or x² + 12x + 36 = 76
We have to add 36, as indicated above, to "complete the square."

Answer:
X = 9.2
Step-by-step explanation:
You have to use the pythagorean theorm, which is a squared + b squared = c squared. Looking at the triangle, the vertical line is 6, and the horizontal is 7.
6squared + 7squared = c squared
85 = csquared
Take the square root of both sides to get rid of the squared on the c.
sqroot of 85 = 9.2

what is the slope of the line
Answer:
The slope is -4/5. Hope this helps!
Step-by-step explanation
To find the slope- Look at both points, Count how many units it is from the other point. Count how many units down and how many units right. Then its rise over run. So how many units down would go ontop of how many units right. This means the answer should be -4/5

A farm has 140 bushels of wheat to sell at his roadside stand .He sells an average of 15 ⅗ blushes each day. Represent the total change in the number of blushes he has sold after 6 days.
Answer:
93 3/5
Step-by-step explanation:
Total bushels to sell = 140
Average sale per day = 15 3/5 bushels
Total change in the number of bushels sold after 6 days ;
Average bushels sold per day * Number of days
15 3/5 * 6
(78/ 5) * 6
468 / 5
= 93 3/5
Change in number sold after 6 days = 93 3/5

what is the value of the expression 2x + 5y when x = 3 and y = 2
Answer:
16
Step-by-step explanation:
If x = 3 and , y = 2.
2 x 3 = 6 and 5 x 2 = 10.
10 + 6 = 16
The value of the expression 2x + 5y when x = 3 and y = 2 is 16.
We have to determine, the value of the expression 2x + 5y when x = 3 and y = 2.
According to the question,
Expression; 2x + 5y
To determine the value of the expression calculation must be done in a single unit following all the steps given below.
The value of expression 2x+5y,
When the value of x = 3 and y = 2,
Therefore,
[tex]= 2x + 5y[/tex]
Substitute the value of x = 3 and y = 2 in the given expression,
[tex]= 2(3)+ 5(2)\\\\= 6 + 10\\\\= 16[/tex]
Hence, The value of the expression 2x + 5y when x = 3 and y = 2 is 16.

The scatterplot below shows the number of hours that some high school students spend on working and on video games.
A graph title Working and Video games has weekly working hours on the x-axis and weekly hours of video games on the y-axis. Points are grouped together and decrease.
Which statement about the scatterplot is true?
In general, the number of hours spent working does not affect the number of hours spent on video games.
In general, the amount of weekly time spent working is equal to the amount of weekly time spent on video games.
As the amount of time spent working increases, the amount of time spent on video games increases.
As the number of hours spent working increases, the amount of time spent on video games decreases.

The cost for an upcoming field trip is $30 per student. The cost of the trip C, in dollars, is a function of the number of students x. Select all the possible outputs for the function defined by C(x)=30x.
Answer:
B. 30
D. 90
Step-by-step explanation:
The cost for an upcoming field trip is $30 per student. The cost of the field trip C, in dollars, is a function of the number of students x. Select all the possible outputs for the function defined by c(x) = 30x. A. 20 B. 30 C. 50 D. 90 E. 100
Given function:
C(x) = 30x
Where,
x = number of students
A. 20
C(x) = 30x
20 = 30x
x = 20/30
= 0.67
x = 0.67 student
B. 30
C(x) = 30x
30 = 30x
x = 30/30
x = 1 student
C. 50
C(x) = 30x
50 = 30x
x = 50/30
x = 1.67 students
D. 90
C(x) = 30x
90 = 30x
x = 90/30
x = 3 students
E. 100
C(x) = 30x
100 = 30x
x = 100/30
= 3.33
x = 3.33 students
Number of students, x should be an whole number
