What you must do for this problem is to re-imagine the equation in "vertex form"
Vertex form:
where "h" shifts the graph to the right if "h" is positive" and to the left if "h" is negative. K shifts the graph up and down.
a=1
h=1
k=0
So, your final answer should be:
Answer:
1
Step-by-step explanation:
9 can't be the answer because 39 is not a prime number
3 can't be the answer because 33 is not a prime number
5 can't be the answer because 75, 35 and 15 are not prime numbers
1 is the answer because 71, 31 and 11 are all prime numbers
hope this helped!!
Answer: C
<u>Step-by-step explanation:</u>
∑ 8()⁽ⁿ⁻¹⁾ from n = 1 to n = 5
n = 1 → 8()⁽¹⁻¹⁾
= 8 =
n = 2 → 8()⁽²⁻¹⁾
= =
n = 3 → 8()⁽³⁻¹⁾
= =
n = 4 → 8()⁽⁴⁻¹⁾
= =
n = 5 → 8()⁽⁵⁻¹⁾
= =
Sum =
= 408.99
