Answer:
no
Step-by-step explanation:
4 is greater than 0
I've searched online on what a graph look like in each given function and based on my online search, the given image of of the equation f(x) is a CUBIC FUNCTION.
A cubic function is like this: f(x) = ax³ + bx² + cx + d
The given graph can have this equation:
y = (x + 1) (x - 1) (x - 3)
Step-by-step explanation:
that is
sum(2^r) for r=1 to n, plus sum(1/2) for r=1 to n.
and that is
sum(2^r) + n/2 for r=1 to n.
2^r is a geometric sequence with 2 being the common ratio (every new term is created by multiplying the previous term by 2).
and since r is starting at 1, the first term a1 = 2.
the formula for the sum of a finite geometric sequence is
Sn = a1×(1 - r^n) / (1 - r)
with r being the common ratio .
so, in our case
Sn = 2×(1 - 2^n) / (1 - 2)
Sn = (2 - 2^(n+1)) / -1 = 2^(n+1) - 2
and so, in total we get
2^(n+1) - 2 + n/2 = 2^(n+1) + (n - 4)/2
Answer:
c is parallel to d
Step-by-step explanation:
the degrees need to be equal in order for them to not intersect at any point, if you set x = 10 as given.
Answer:
3^(k+2) = 9m/ 26
Step-by-step explanation:
Let 3^k = y :
y×3^3-y = m
26y = m
26×3^k = m
3^(k+2) = m/26×3^2
Therefore 3^(k+2) = 9m/26
