Answer:
<em>f(x) = x² (2+i)x-15-3i</em>
Step-by-step explanation:
Since the zeros of the equation are -3 and 5+i, hence the factors of the polynomial in x is (x+3) and (x-(5+i))
Multiplying both factors
f(x) = (x+3)(x-(5+i))
f(x) = (x²-(5+i)x+3x -3(5+i))
f(x) = x² - (5+i- 3)x -15-3i
f(x) = x² (2+i)x-15-3i
<em>hence the required polynomial function in x is f(x) = x² (2+i)x-15-3i</em>
Answer:
72
Step-by-step explanation:
First differences are ...
18 -17 = 1
22 -18 = 4
31 -22 = 9
47 -31 = 16
We observe that these are square numbers. The next square number is 25, so we expect the next number in sequence to be ...
47 +25 = 72
It is m4 in my opinion i’m not sure tho
Answer:
128 km²
Step-by-step explanation:
a²+b²=c²
So, one of the sides equals 128 square rooted, because 8²=64, and 64 times 2 equals 128. The area of a square is side times side, so it's side². So, instead of simplifying the square root of 128, get rid of the square root. The answer is 128 km²
