Answer:
the modulus of a complex number z = a + bi is:
Izl= √(a²+b²)
The fact that n is complex does not mean that n doesn't has a real part, so we must write our numbers as:
m = 2 + 6i
n = a + bi
Im + nl = 3√10
√(a² + b²+ 2²+ 6²)= 3√10
√(a^2 + b^2 + 40) = 3√10
squaring both side
a²+b²+40 = 3^2*10 = 9*10 =90
a²+b²= 90 - 40
a²+b²=50
So,
|n|=√(a^2 + b^2) = √50
The modulus of n must be equal to the square root of 50.
now
values a and b such
a^2 + b^2 = 50.
for example, a = 5 and b = 5
5²+5²=25+25= 50
Then a possible value for n is:
n = 5+5i
Answer:
Step-by-step explanation:
8x = -1
x = 
The absolute value lines || means the answer will always be positive, so the final answer is positive 1/8.
The solution is when the two functions meet x=2. The green function is f(x), and the red is g(x).
Answer:
0.75-0.5=0.25
Step-by-step explanation:
Subtract the minimum data value from the maximum data value to find the data range. In this case, the data range is 0.25 or 1/4.
