The answer is the first one; it is an arithmetic sequence with a common difference of -40.
Answer:
A. Correct choice is C
B. Correct choice is B
Step-by-step explanation:
4 times the number x is 4x.
The sum of 4 times the number x and 26 is 4x+26.
The sum of 4 times the number x and 26 is 130, then
4x+26=130.
Correct option is option C.
Solve this equation:
4x=130-26,
4x=104,
x=26.
Answer:
Neither even nor odd.
Step-by-step explanation:
f(x) = 2(x + 1)^3 = 2x^3 + 18x^2 + 54x + 54
f(-x) = -2x^3 + 18x^2 - 54x + 54
If it was even f(x) would be = f(-x) so it is NOT EVEN.
-f(x) = 2x^3 - 18x^2 + 54x - 54
So f(-x) is not = -f(x) so it is not ODD either.
Probability of heads or tails is .5
so you do (.5)^3 and you get D = 0.125
Firstly , we will check continuity at x=1
we can use method
Suppose, f(x) is continuous at x=c
then it must satisfy


firstly , we can find limit


so, we get

now, we can find f(1)

so, we got

so, this is continuous at x=1
Hence , option-D...........................Answer
