I think the answer is 90?
Answer:C)bimodal
Step-by-step explanation:
Its bi modal because there is a sudden change in the numbers but if you split the graph in half the two graphs are almost symmetrical.
Answer:
y = x³ + 10.5x² + 31x + 13
Step-by-step explanation:
Complex roots (roots that have imaginary terms) always come in conjugate pairs. So if one root is -5 + i, there's another root that's -5 − i.
So the polynomial is:
y = (x + 1/2) (x − (-5 + i)) (x − (-5 − i))
Distributing:
y = (x + 1/2) (x² − (-5 + i)x − (-5 − i)x + (-5 + i)(-5 − i))
y = (x + 1/2) (x² + 5x − ix + 5x + ix + (-5 + i)(-5 − i))
y = (x + 1/2) (x² + 10x + (-5 + i)(-5 − i))
y = (x + 1/2) (x² + 10x + 25 + 5i − 5i − i²)
y = (x + 1/2) (x² + 10x + 25 + 1)
y = (x + 1/2) (x² + 10x + 26)
y = x(x² + 10x + 26) + 1/2(x² + 10x + 26)
y = x³ + 10x² + 26x + 1/2x² + 5x + 13
y = x³ + 10.5x² + 31x + 13
Answer:
The answer to your question is: J(k(-1)) = 2
Step-by-step explanation:
Data
J(x) =
k(x) = 9 - x
Find J(k(-1)
Process
k(-1) = 9 - (-1)
k(-1) = 9 + 1
k(-1) = 10
J(k(-1)) =
J(k(-1)) =
J(k(-1)) = 2
Answer:
Step-by-step explanation:
x = smaller number, y = bigger number
7x + 2y = 635
7y - 2x = 871....rearrange...-2x + 7y = 871
7x + 2y = 635....multiply by 2
-2x + 7y = 871...multiply by 7
----------------------------------
14x + 4y = 1270 (result of multiplying by 2)
-14x + 49y = 6097 (result of multiplying by 7)
--------------------------------add
53y = 7367
y = 7367/53
y = 139
7x + 2y = 635
7x + 2(139) = 635
7x + 278 = 635
7x = 635 - 278
7x = 357
x = 357/7
x = 51
solution : x = 51 and y = 139 or (51,139)
