Which of the following sequences is an arithmetic sequence? 1, 2, 4, 8, 18, ... 10, 12, 14, 16, 18, ... 200, 100, 50, 25, ... 4,

The sequence 10, 12, 14, 16, 18, ... is an arithmetic sequence, with the common difference being 2.
Answer:
1
Step-by-step explanation:
Scientific notation is the way that scientists easily handle very large numbers or very small numbers. For example, instead of writing 0.0000000056, we write 5.6 x 10-9. So, how does this work?
We can think of 5.6 x 10-9 as the product of two numbers: 5.6 (the digit term) and 10-9 (the exponential term).
Here are some examples of scientific notation
Answer:
135x^3 + 3x^2 - 46x + 8.
Step-by-step explanation:
(5x-1)(3x+2)(9x-4)
= (5x - 1)(27x^2 + 18x - 12x - 8)
= (5x - 1)(27x^2 + 6x - 8)
= 5x(27x^2 + 6x - 8) - 1(27x^2 + 6x - 8)
= 135x^3 + 30x^2 - 40x - 27x^2 - 6x + 8
= 135x^3 + 3x^2 - 46x + 8.
you must substitute x in the equation given :)
examples:
when x is -2
therefore, y = 2(-2) + 3
y = -1
when x is 0
therefore, y = 2(0) + 3
y = 3
when x is 1
therefore, y = 2(1) + 3
y = 5
when x is 3
therefore, y = 2(3) + 3
y = 9
for (b) you only have to plot based on the table ;)
