The 10th term round to the nearest thousandth of the geometric progression is found as 0.001.
Explain the term geometric progression?A sort of sequence known as geometric progression (GP) is one in which each following phrase is created by multiplying every preceding word by a fixed number, or "common ratio." This progression is sometimes considered to as a pattern-following geometric sequence of numbers.For the stated sequence:
5, 2,4/5,...
Check for AP:
a₂ - a₁ = 5 - 2 = 3
a₃ - a₂ = 4/5 - 2 = -6/10 = -3/10
As the common difference is not same, it is not an AP.
Check for GP:
a₁ = 5
a₂ = a₁ q²⁻¹
a₂ = 5q = 2
a₃ = a₁q³⁻¹
= a₁q²
a₃ = 5q² = 4/5
As,
a₂/ a₁ = 2/5
a₃/a₂ = 2/5, it is an GP
Thus,
a₁₀ = a₁qⁿ⁻¹
= 5*(2/5)⁹
= 0.001
Thus, the 10th term round to the nearest thousandth of the geometric progression is found as 0.001.

The frequency table displays the number of ill patients in each age group. The first two plots are incorrect because the sum of the dots connecting the numbers 24, 25, 26, 27, 28, and 29 in the first two plots is 3, but not in the other two plots.
In conclusion, there are only 4 ill individuals when the dots from the 30-34 age range on the first plot are added together. There are a total of 6 cases in that age group on the second graph. As a result, the second dot plot is the one that matches the frequency table.

This table shows values represented by an exponential function x= 0,1,2,3,4,5,6 y=1,3,9,27,64,125,216 what is the average rate of change for this function for the interval from x=2 to x=4?
27.5 is the answer
For this case we know that the average rate of change of a function is given by this general expression:
m = f(b) - f(a)/ b-a
For this special case from the info in the table we have:
a =2 , f(2) = 9
a =4 , f(4) = 64
And replacing the data with the average rate formula we got:
m = 64 - 9/4 - 2 = 27.5
And then the best answer for this case would be:

We have to choose an equivalent expression to the given expression 2(4f + 2g)
Consider the given expression 2(4f + 2g)
Apply Distributive property, a( b + c) =ab + ac
We have,
a = 2, b = 4f and c = 2g
2(4f + 2g) = 8f + 4g
Now, take 4 common from each term, we have,
8f + 4f = 4 (2f + g)
Now, We have,

The shapes in the figure are:
Triangle: Base = 1, Height = 6Triangle: Base = 5, Height = 8Square: Length = 2Rectangle: Length = 7; Width = 6Using the area formula of each shape, the total area is:

Total = 69
Hence, the obstacle has a total area of 69 square feet.

The cost of one pen is Rs 15.
How to find the cost of one pen?It is given that Ruby paid with a 500 rupee note and got Rs 90 back.
This means that she spent 410 rupees.
Therefore the cost of 24 books and 5 pens is Rs 410.
Let the cost of books be x and the cost of pens be y.
Therefore, we can form the following equations:
24x + 5y = 410 (1)
12x + 10y = 280 (2)
We have to find the value of y.
Multiply the second equation by 2:
24x + 20y = 560 (3)
Now subtract the first equation from the third equation:
24x + 20y - 24x - 5y = 560 - 410
15y = 150
y = 15.
The variable y represents the cost of one pen.
