Answer:
P(x) = 
+ 
+ 
Step-by-step explanation:
x(x + 1/6)(x + 3) = P
x(
+ 3x + 1/6(x) + 1/2) = P
x ( + 19/6(x) + 1/2) = P
+ + = P(x)
305 plus 90= 395. Found by doing 395-90
Answer: First Option : Sₙ= n/2(a₁ + aₙ)
Step-by-step explanation:
The nth partial sum of an arithmetic sequence or the sum of the first n terms of the arithmetic series can be defined as the sum of a finite number of term in an arithmetic sequence.
It is calculated using the formula:
Sₙ= n/2(a₁ + aₙ)
Where :
a₁ = First term
aₙ = last term
n = number of terms
Answer:
the difference of 12 and 5 is 7 so it would be 0
You just have to plug in each thing:
So f(0):
3(0)^2 - 4 = -4
so its not A
f(-2) and f(2):
3(-2)^2 - 4
3(2)^2 -4
now we don't even have to calculate these, anything to the power of an even number is a positive number so -2^2 and 2^2 both equal 4
B is correct, so you can do the others if you want to check, but if B is true the others shouldn't be true.
