Answer:
B and D
Step-by-step explanation:
they're the explanations.
What we’re looking for is the
value of k that will satisfy the equation.
The solution would be like this
for this specific problem:
5k =1 (mod
26)
Check how 5*5
= 25 = -1 (mod 26)
In this way,
5*(-5) = -5*5 = -25 = -(-1) = 1 (mod 26)
Thus, k = -5
= 21 (mod 26)
And 5^-1 =
21 (mod 26)
I am hoping that this answer has
satisfied your query and it will be able to help you in your endeavor, and if
you would like, feel free to ask another question.
Y = mx + b
where m = slope and b = y-intercept
y = (9/4)x - 4
or 4y = 9x - 16
Answer:
$15,339
Step-by-step explanation:
C(x) = 0.5x² − 100x + 20,339
Since this is a parabola, the minimum cost is at the vertex:
x = -b / (2a)
x = -(-100) / (2 × 0.5)
x = 100
So the minimum cost is:
C(100) = 0.5(100)² − 100(100) + 20,339
C(100) = 15,339
