Modulus: If z1=-2+3i and z2=1+2i calculate, |z1|, |z2|, and |z1+2z2|

marin [14]

$|z_1|=\sqrt{(-2)^2+3^2}=\sqrt{4+9}=\sqrt{13}\\
|z_2|=\sqrt{1^2+2^2}=\sqrt{1+4}=\sqrt{5}\\\\
z_1+2z_2=-2+3i+2(1+2i)=-2+3i+2+4i=7i\\
|z_1+2z_2|=\sqrt{0^2+7^2}=7

Mars2501 [29]

Answer:

$- m(7m + 3) - 4 {m}^{2} \\ - 7m^{2} - 3m - 4 {m}^{2} \\ - 11 {m}^{2} - 3m$

Which equation represents the line that passes through points B and C on the graph? 2 4 3 B 3 4 5 ภา

777dan777 [17]

The point B has coordinates (-4,2) and C has coordinates (-2,-2). We are going to calculate the slope of the line

$m=\frac{y2-y1}{x2-x1}=\frac{-2-2}{-2-(-4)}=-2$

Then, we are going to calculate the intercept using the slope m=-2 and the point (-4,2).

y=mx+b

2 = -2*(-4)+b

Isolating b we get

2-8=b= -6

The equation would be

y=-2x-6, option A

The first five terms of an arithmetic sequence are 8, 13/2, 5, 7/2, and 2. Which function, f(x), could be used to describe the x

juin [17]

Answer:

f(x) = 8 - 1.5x

Step-by-step explanation:

Here, we want to write a function that can be used to describe the x th term of the sequence

Mathematically, this can be calculated by looking at the numbers in the sequence

The difference between each successive term

is -1.5 ( 6.5-8, 3.5 -5)

So the formula for then x th term will be;

f(x) = 8 - 1.5x

where x refers to the number of the term , for example the 4th term
