Common difference
t_3-t_26.8-51.8#4
The formula is
a_n=10n-14Put n=8
a_8=10(8)-14=80-14=66Answer:
3) d = 1.8
4) a₈ = 66
5) a) 138
b) 55
c) [tex]a_n=55n+83[/tex]
Step-by-step explanation:
Question 3
The common difference of an arithmetic sequence is the difference between consecutive terms.
Therefore, to find the common difference, subtract one term from the next:
⇒ d = 5 - 3.2
⇒ d = 1.8
Question 4
Given arithmetic sequence: [tex]a_n=10n-14[/tex]
To find the 8th term, substitute n = 8 into the equation:
[tex]\implies a_8=10(8)-14[/tex]
[tex]\implies a_8=80-14[/tex]
[tex]\implies a_8=66[/tex]
Question 5
General form of an arithmetic sequence:
[tex]a_n=a+(n-1)d[/tex]
where:
[tex]a_n[/tex] is the nth terma is the first termd is the common difference between termsa) The first term is the initial amount Mrs Speas has in her bank account:
a = 138b) The common difference is the amount she deposits each week:
d = 55c) The iterative rule for the amount of money she has after n weeks is:
[tex]\implies a_n=138+(n-1)55[/tex]
[tex]\implies a_n=138+55n-55[/tex]
[tex]\implies a_n=55n+83[/tex]

Find the indicated sum.
Answers
Answer:
-5
Step-by-step explanation:
The starting point is at 1 and the stopping is at 5(if you want to know where to find these, look at the image attached).
For i=1, we have i-4, which would be 1 - 4, or -3.
For i=2, we have i-4, which would be 2 - 4, or -2.
For i=3, we have i-4, which would be 3 - 4, or -1.
For i=4, we have i-4, which would be 4 - 4, or 0.
For i=5, we have i-4, which would be 5 - 4, or 1.
We would add these 5 values:
-3 + (-2) + (-1) + 0 + 1
This gives us -5

Write equations for the horizontal and vertical lines passing through the point (-6,1)
Answers
Answer:
y = 1 and x = - 6
Step-by-step explanation:
The equation of a horizontal line parallel to the x- axis is
y = c ( where c is the value of the y- coordinates the line passes through )
The line passes through (- 6, 1 ) with y- coordinate 1 , then
y = 1 ← equation of horizontal line
The equation of a vertical line parallel to the y- axis is
x = c ( where c is the value of the x- coordinates the line passes through )
The line passes through (- 6, 1 ) with x- coordinate - 6 , then
x = - 6 ← is equation of vertical line
Hi! ❤️ , im looking for some help here. ill give brainliest if able to.
Answers
Answer:
A. 2^11
Step-by-step explanation:
The exponent rule you want to use here is that, when multiplying numbers with the same base, you add their exponents and keep the base. Here, you're explicitly being told to multiply 2^4 and 2^7, meaning you should add 4 and 7 and make the sum the power you're raising 2 to. 4 + 7 is 11, so the answer is A. 2^11
B is wrong because you do not multiply the exponents.
C is wrong because there is no multiplication involved at all... strange.
D is wrong because you do NOT multiply the base. Keep it!

Answers

Answer:
$74,828
Step-by-step explanation:
We assume the numbers in the problem statement here mean the cost of living index is $58,000 in Illinois and $70,000 in California. That means the costs in California are 70/58 = 35/29 times those in Illinois.
In order to maintain the same relative lifestyle, you would need to earn (35/29) times $62,000 in California, or ...
(35/29)×$62,000 ≈ $74,828 . . . . acceptable CA salary

A paint mixture is made up of 3/20 red paint and 9/20 blue paint, and the rest is white paint. What fraction of the mixture is white paint?
The paint is sold in 5-litre containers. How many litres of red paint are needed for each container?
How many litres of blue paint are needed for each container?
Answers
Answer:
2/5
3/4
2 1/4
Step-by-step explanation:
red paint: 3/20
blue paint: 9/20
white paint: x
What fraction of the mixture is white paint?
x + 3/20 + 9/20 = 1
x + 12/20 = 20/20
x = 8/20 = 2/5
2/5 of the paint mixture is white paint.
The paint is sold in 5-litre containers. How many litres of red paint are needed for each container?
3/20 × 5 litre = 3/4 litre
Each container needs 3/4 liter of red paint.
How many litres of blue paint are needed for each container?
9/20 × 5 litres = 9/4 litres = 2 1/4 litres
Each container needs 2 1/4 liter of blue paint.
