Find the next two terms of the sequence:
2050, 1990, 1930, 1870, 1810, 1750
The next two terms of the sequence are
Answer:
The answer is 1690, and then 1630
Step-by-step explanation:
2050, 1990, 1930, 1870, 1810, 1750, 1690, 1630
Each number is going down by 60
===============================================================
Explanation:
This is an arithmetic sequence. We are adding -60 to each term to get the next term. Put another way, we are subtracting 60 from each term to get the next.
term 1 = 2050
term 2 = (term1) + (-60) = (term1) - 60 = 2050 - 60 = 1990
term 3 = (term2) + (-60) = (term2) - 60 = 1990 - 60 = 1930
term 4 = (term3) + (-60) = (term3) - 60 = 1930 - 60 = 1870
and so on
Keeping this pattern up, we get these next two terms
1750 - 60 = 1690
1690 - 60 = 1630
which are the two answers
-----------
If you want to use a formula, then a1 = 2050 is the first term and d = -60 is the common difference. We get this nth term formula
a(n) = a1 + d(n-1)
a(n) = 2050 + (-60)(n-1)
a(n) = 2050 - 60n + 60
a(n) = -60n + 2110
Then note that six terms of the sequence are given to us. This means we want to find the 7th term, so we plug in n = 7 to get
a(n) = -60n + 2110
a(7) = -60(7) + 2110
a(7) = -420 + 2110
a(7) = 1690
The 7th term is 1690
Repeat for n = 8
a(n) = -60n + 2110
a(8) = -60(8) + 2110
a(8) = -480 + 2110
a(8) = 1630
The 8th term is 1630
DVD players are going out of fashion in the modern era. If 400,000 DVD players were sold this year and sales are declining at a rate of 31% per year, how many will be sold 3 years from now?
130,000
131,404
128,000
399,876
Answer:
c
Step-by-step explanation:
Answer:
399,876
Step-by-step explanation:
So, 400,000 DVD sales with a 31% decline means in the first year following, there will be a decline of 124,000 DVDs sold. So we need to take 400,000-124,000 which equals a starting point for your two is 276,000 dvds. Then, add 123,876, which gives you 399,876.

Answer:
11.3
Step-by-step explanation:
i used the theorem of Pythagoras
Answer:
11.3
Step-by-step explanation:
In a right angled triangle: the square of the hypotenuse is equal to
the sum of the squares of the other two sides.
[tex]8^{2} + 8^{2} = x^{2}[/tex] (x is the hypotenuse)
64 + 64 = [tex]x^{2}[/tex]
[tex]x^{2}[/tex] = 128
=> x = [tex]\sqrt{128}[/tex] = 11.3137085 = 11.3

Answer:
x=-2 and x=-8
Step-by-step explanation:
(x+5)=3
Subtract 5 from both sides, to isolate x
x=-2
-(x+5)=3
Distribute the -
-x-5=3
Add 5 to both sides to isolate x
-x=8
Multiply both sides by -
x=-8

What is the twentieth term of the arithmetic sequence described by the
equation an= 3n - 10?
Answer:
The twentieth term is 50.
Step-by-step explanation:
The equation that describes the arithmetic sequence describes it's "general term", which means that all the numbers in that sequence must follow that equation. For instance, if we want to find the first term of the sequence we must make a = 1 and we have:
a1 = 3*1 - 10
a1 = -7
Therefore to find the twentieth term we need to make n equal to 20. This is done below:
a20 = 3*20 - 10
a20 = 60 - 10
a20 = 50
The twentieth term is 50.

Solve the following equation:
12(b+2)+3b=−1
Enter your answer as a fraction.
Answer: -5/3
Step-by-step explanation:
12(b + 2) + 3b = -1
12b + 24 + 3b = -1
15b + 24 = -1
15b = -1-24
b = -25/15 = -5/3
The solution to the equation 12(b+2) + 3b = -1 is b = -5/3.
What is the solution to the given equation?Given the equation in the question:
12( b + 2 ) + 3b = -1
To solve the equation 12( b + 2 ) + 3b = -1, first apply the distributive property.
Distribute the 12 across the terms inside the parentheses:
12( b + 2 ) + 3b = -1
12×b + 12×2 + 3b = -1
Simplifying, we get:
12b + 24 + 3b = -1
Collect and combine the like terms on the left side of the equation:
12b + 3b + 24 = -1
15b + 24 = -1
Subtract 24 from both sides of the equation:
15b + 24 - 24 = -1 - 24
15b = -1 - 24
15b = -25
Divide both sides by 15:
b = -25/15
Simplify
b = -5/3
Therefore, the value of b is -5/3.

Show the Euler-Descartes formula holds for the Great Pyramid of Cheops
Answer:
For the great pyramid of Cheops, V + F = E + 2 gives 5 + 5 = 8 + 2 which proves Euler-Descartes formula
Step-by-step explanation:
The great pyramid of Cheops is a square based pyramid therefore we have;
V + F = E + 2
Where:
V = Vertices
F = Faces
E = Edges
Hence, we have for a square pyramid;
V = 5 vertices (One at the peak, and four at the base edges)
F = 5 faces (The four lateral or side faces and the base)
E = 8 edges ( The four lateral edges and the four base edges)
Hence;
5 + 5 = 8 + 2 which proves Euler-Descartes formula.

A bag contains 3 red, 4 blue, and 6 yellow marbles. One marble is selected at a time, and once a marble is selected, it is replaced. Find each probability. P(red and yellow)
Answer:
red = 3/13
yellow = 6/13
blue= 4/13
Step-by-step explanation:
breainliest really needed!!
The probability of selecting the red marble and yellow marble is 18/169.
What is the probability?Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.
We know that, probability of an event = Number of favourable outcomes/Total number of outcomes.
Given that, a bag contains 3 red, 4 blue, and 6 yellow marbles.
Total number of outcomes = 3+4+6=13
Probability of selecting red marble = 3/13
Probability of selecting yellow marble = 6/13
So, P(red and yellow) = 3/13 × 6/13
= 18/169
Therefore, the probability of selecting the red marble and yellow marble is 18/169.
