Answer:
10
Step-by-step explanation:
We are going to substitute x = 3 - i into the expression x² - 6x
* Remember than i² = (√-1)² = -1. so when we multiply and get i² we're going to transform it into -1.*
⇒
Thus, x² - 6x = 10 when x = 3-i
(-8/2)^2 = 16
What is the function written in vertex form?
A.f(x) = 3(x + 4)2 – 6
B.f(x) = 3(x + 4)2 – 38
C.f(x) = 3(x – 4)2 – 6
D.f(x) = 3(x – 4)2 – 38
Answers
f(x) = 3(x2 - 8x + 16) + 10 - 3(16)
f(x) = 3(x - 4)(x - 4) + 10 - 48
f(x) = 3(x - 4)2 - 38
Therefore, the function written in vertex form is:
D.f(x) = 3(x – 4)2 – 38
y = a(x-h)^2 + k
We have the given equation:
f(x) = 3x^2 – 24x + 10
f(x) - 10 + 3(16) = 3(x^2 -8x + 16)
f(x) + 38 = 3(x - 4)^2
f(x) = 3 (x-4)^2 -38
Then, the correct answer is D.

1980 / 180 = 11 , so the polygon has 13 sides and 13 angles.
If the polygon is regular, then all the angles are equal.
Each interior angle is 1980/13 = 152.308 degrees (rounded)

Answer:

Step-by-step explanation:
The given translation is
Which means that the original figure will be moved 3 units to the right and 8 units downwards.
Remember, when it comes to translations, when we subtract units to that means the figure will be moved rightwards. And if we subtract units from
, that means the figure will be moved downwards.
So, the original figure has as vertex B(1,2). If we apply the transformation to its vertical cordinate , we would have
Therefore, the right answer is the third choice -6.
