The 1st, 2nd and 3rd terms of a geometric progression are the 1st, 9th and 21st terms of an arithmetic progression respectively. Given that the 1st term of both progressions is 8 and the common ratio of the geometric progression, r not equation of 1 .Find .
a.The value of r
b.the 4th term of each progression
a. The value of r = 3, -1/2.
b. The 4th term of each progression;
for r = 3; AP = 14, GP = 216.for r = -1/2; AP = 7/2, GP = 1/2.What is defined by AP and GP?An Arithmetic Progression (AP) is a collection of terms with the same differences between them. In a Geometric Progression (GP), each successive term is created by multiplying the common ratio by previously acted.As, per the given question;
Let the first three terms of GP be a, ar, and ar².
The 1st, 2nd and 3rd terms of a GP equals 1st, 9th and 21st terms of an AP respectively.
First term are equal; a = a2nd term GP = 9th term of AP; ar = a + 8d. 3rd term GP = 21st term of AP; ar² = a + 20d.where, 'r' is the common ratio in GP and 'd' is the common difference in AP.
Part 1: Multiply equation 1 by 5 and 2 by 2 and subtract 1 from 2.
2ar² - 5ar - 3a = 0
Put a = 8 and solving.
16r² - 40r - 24 = 0.
Factorising the above equation;
(r - 3)(2r + 1) = 0
Thus, r = 3 and r = -1/2
Part 2:
Case 1: For r = 3; a =8;
ar = a + 8d
d = 2.
Thus, 4th term = a + 3d
= 8 + 3×2
4th term = 14.
For GP;
4th term = ar³
= 8(3)³
4th term = 216.
Case 2: For r = -1/2; a =8;
ar = a + 8d
d = -3/2
Thus, 4th term = a + 3d
= 8 + 3×(-3/2)
4th term = 7/2
For GP;
4th term = ar³
= 8(-1/2)³
4th term = -1.
Therefore, the values for the r and 4th term is estimated.

A coordinate system is geometry is a system that employs one or more integers, or coordinates, to define the position of points. The rules that maps the other vertices of the figure to their images is T<-2, -7> (x,y).
What are coordinates?
A coordinate system is geometry is a system that employs one or more integers, or coordinates, to define the position of points or other geometric components on a manifold such as Euclidean space.
Given that Sanjay determined that one vertex of a figure was mapped to its image by translating the point 2 units left and 7 units down.
In order to translate coordinates, 2 units left we need to subtract 2 units from the x-coordinate of the point, while to translate the point 7 units down we need to subtract 7 from the y-coordinate of the point.
Therefore, the rule that maps the other vertices of the figure to their images is, (x¹,y¹)=(x-2,y-7), or it can bse written as T<-2,-7> (x, y),
where x¹ and y¹ are the coordinates of the points after transliteration.
Hence, the rule that maps the other vertices of the figure to their images is T<-2,-7> (x, y,).

How many ounces of pure acid should be added to 300 ounces of 12% acid solution to produce a solution that is 25%?
Answer:
52 ounces
Step-by-step explanation:
You want the number of ounces of pure acid to be added to 300 ounces of 12% acid solution to produce a solution that is 25%.
SetupLet x represent the number of ounces of acid added. Then the amount of acid in the desired solution is ...
12%(300) +100%(x) = 25%(300 +x)
Solution stepsSubtracting (25%(x) +12%(300)) from both sides, we get ...
75%(x) = 13%(300)
Dividing by the coefficient of x, we find ...
x = (13)(300)/75 = 52
52 ounces of pure acid should be added to make a 25% acid solution.
__
Additional comment
In the original solution, there are 12%(300) = 36 ounces of acid. In the 352 ounces of final solution, there will be 36+52 = 88 ounces of acid, a proportion of 88/352 = 1/4 = 25%.

C = (Slope)m + d
Where d is y-intercept = 40
Slope = difference in y's coordinate / difference in x's coordinate
Slope = (70 - 55)/(10 - 5)
Slope = 15/5 = 3
So the equation would be ;
C = 3m + 40

But at the end of the month the peanuts had not sold well, so, in order to sell 90 pounds of peanuts, the manager decided to mix the 90 pounds of peanuts with some cashews and sell the mixture for $3.50 per pound. How many pounds of cashews should be mixed with the peanuts to ensure no change in the revenue?
The number of pounds of cashews should be mixed with the peanuts to ensure no change in the revenue is; 360 pounds
How to Solve Algebra Word Problems?Let the number of pounds of cashews be x.
Now, we are told that A nut store normally sells cashews for $4.00 per pound. Thus;
Cost of x pounds of cashews = $4x
He wants to mix the above with 90 pounds of peanuts and sell the mixture for $3.5 per pound. Thus, the equation here is;
((90 * 1.5) + (4x))/(x + 90) = 3.5
135 + 4x = 3.5(x + 90)
135 + 4x = 3.5x + 315
4x - 3.5x = 315 - 135

The length of a rectangle is 6 meters shorter than 4 times its width. The area of the rectangle is 238 square meters. How long and wide is the rectangle?
The width and length of the rectangle given its area is 8.5 meters and 28 meters respectively.
Area of rectangleLength of the rectangle = (4w - 6) metersWidth of the rectangle = wArea of rectangle = 238 square metersArea of a rectangle = Length × width
Substitute the parameters238 = (4w - 6) × w
238 = 4w² - 6w
Change to quadratic equation4w² - 6w - 238 = 0
Using quadratic formulaa = 4
b = -6
c = -238
w = -b ± √b² - 4ac / 2a
= -(-6) ± √(-6)² - 4(4)(-238) / 2(4)
= 6 ± √36 - (-3808) / 8
= 6 ± √36 + 3808 / 8

Answer:
220
Step-by-step explanation:
You want to use differences to find the pattern and the next term in the sequence 3, 8, 15, 28, 51, 88, 143.
First differencesSubtracting each term from the next, we find the sequence of first differences to be ...
5, 7, 13, 23, 37, 55
Second differencesThe first differences are not constant, so we know the sequence is not linear. They are not in an arithmetic progression, so we know the sequence is not quadratic. They do not have a common ratio, so we know the sequence is not exponential.
The second differences are the differences of the sequence of first differences. They are ...
2, 6, 10, 14, 18
Third differencesThe differences of the terms of the 2nd-difference sequence are constant: 4.
4, 4, 4, 4, 4
Constant 3rd differences mean the original sequence can be described by a 3rd degree polynomial. The coefficients found by a calculator are shown in the attachment.
Next termSince we know the third differences are constant, we can work our way back up the chain of differences to find the next term of the original sequence.
next 2nd difference = 18 +4 = 22
next 1st difference = 55 +22 = 77
next sequence term = 143 +77 = 220
The eighth term should be 220.

the correct option is the first one (counting from the top).
The true statement is:
"The leading coefficients of f(x) and g(x) are opposites"
Which statement is true?We know that f(x) and g(x) are quadratic functions, and the sum of these two functions is shown in the graph.
We can see that the sum gives a linear graph, so the terms with the exponents of 2 are cancelled by the sum.
This only can happen if f(x) and g(x) have opposite (same absolute value but different sign) leading coefficients, so the quadratic terms are cancelled when we add the functions.
For example in f(x) = 2*x^2 + 3x + 4
g(x) = -2x + x + 13
If we add these two functions, we would end with a line.
With that in mind we can conclude that the correct option is the first one (counting from the top).
