6
,
−
30

Step-by-step explanation:
Rewrite in vertex form and use this form to find the vertex (
h
,
k
)
.
The population of the fish is given by P(t) = 750(1 + 0.083)^t; where t is the number of years after 2005.
Here, t = 2050 - 2005 = 45
Population in 2050 = 750(1.083)^45 = 750(36.16) = 27,123
Answer:
A scatter plot to the right shows a very strong association.
Step-by-step explanation:
Because a scatter plot to the right shows that both variables are positive and they both increase, so it shows a strong association between those variables.
Answer:
an = 12 -7(n-1)
an = 19-7n
Step-by-step explanation:
The explicit formula for an arithmetic sequence is
an = a1 +d(n-1) where a1 is the first term and d is the common difference
a1 =12
We find d by taking the second term and subtracting the first term
d = 5-12
d = -7
an = 12 -7(n-1)
We can simplify this
an = 12 -7n+7
an = 19-7n
(2-7i)(9+5i)
18+10i-81i-35i^2
The answer is 35i^2 - 71i +18
