Consider Z1= 4-4 radical 3i and Z2= -16 i. What is Z1-Z2?
goldfiish [28.3K]

Answer:

Option (3)

Step-by-step explanation:

Z_1=4-4\sqrt{3}i

Z_2=-16i

Z_1-Z_2=(4-4\sqrt{3}i)-(-16i)

            =4-4\sqrt{3}i+16i

            =4-(4\sqrt{3}i-16i)

            =4-4(\sqrt{3}-4)i

Therefore, Option (3) will be the correct option.

Can someone help me find the volume of these?
snow_lady [41]
The volume of the triangular prism is:
 
V = (1/2) * (b) * (h) * (H)
 Where,
 b: base of the triangle
 h: triangle height
 H: prism height
 Substituting:
 V = (1/2) * (9) * (12) * (19)
 V = 1026 cm ^ 3

 
The volume of the cylinder is:
 
V = (pi) * (r ^ 2) * (h)
 Where,
 r: radio
 h: height
 Substituting:
 V = (3.14) * ((14/2) ^ 2) * (11)
 V = 1692.46 yd^3

Here's a graph of a linear function. Write the
Natalija [7]

Answer:

\large\boxed{y=\dfrac{1}{4}x+3}

Step-by-step explanation:

The slope-intercept form of an equation of a line:

y=mx+b

m - slope

b - y-intercept → (0, b)

From the graph we have the points (4, 4) and (0, 3) → b = 3.

We have the equation:

y=mx+3

The formula of a slope:

m=\dfrac{y_2-y_1}{x_2-x_1}

Put the coordinates of the points:

m=\dfrac{3-4}{0-4}=\dfrac{-1}{-4}=\dfrac{1}{4}

Finally we have:

y=\dfrac{1}{4}x+3
