Part A

Looking at the graph

we have that

z1 ------> the coordinates are (3,5)

so

the standard form is z1=3+5i

z2 ------> the coordinates are (6,-3)

so

the standard form is z2=6-3i

Find out the distance between them

z2-z1=(6-3i)-(3+5i)

z2-z1=(6-3)+(-3i-5i)

z2-z1=3-8i

Find out the magnitude of the complex number (Applying the Pythagorean Theorem)

\begin{gathered} d_{z1z2}=\sqrt{(3)^2+(-8)^2} \\ d_{z1z2}=\sqrt{73} \end{gathered}

The distance between z1 and z2 is the square root of 73 units

Part B

Find out the conjugate of z2

we have

z2=6-3i

so

Remember that

You find the complex conjugate simply by changing the sign of the imaginary part of the complex number

therefore

The conjugate of z2 is (6+3i)

To find out geometrically change the sign of the y-coordinate (imaginary part) of the complex number (Reflect the given point over the x-axis)

A jug has a maximum capacity of 14 liters. is filled to 60% of its capacity, and then poured out at a rate of 60 mL/s. Which of
ZanzabumX [31]

Answer:

W(x) = 3.4 L - (25/1000)(L/s)*x

Step-by-step explanation:

          it a tip

W(x) = 3.4 L - (25/1000)(L/s)*x

The maximum of the jug is 4 L.

now, the jug is 85% filled, then the amount of water in the jug is:

(85%/100%)*4L = 0.85*4L = 3.4L

Now, we pour 25 mL each second, so we could write a linear equation as:

W(x) = 3.4L - (25ml/s)*x

where x is the number of seconds that passed since the beginning,

But we want to write this in Liters, we have that:

1L = 1000mL.

Then 1mL = (1/1000) L

then we can write 25 mL as:

25m L = 25*(1/1000) L = (25/1000) L

Then we can write the equation as

W(x) = 3.4 L - (25/1000)(L/s)*x

which is the amount of water remaining in the jug after x seconds.

Find the length of the median and the missing base. Be sure to show all your work. NO LINKS!!!​
dezoksy [38]

Answer:

The bottom is  11

The median is  12

Step-by-step explanation:

The median is the average of the top and bottom

(13+ 2x-3) /2 = 4x-16

Combine like terms

(10+2x)/2 = 4x-16

Divide by 2

5+x = 4x-16

Subtract x from each side

5+x-x = 4x-16-x

5 = 3x-16

Add 16 to each side

5+16 = 3x-16+16

21 = 3x

Divide by 3

21/3 = 3x/3

7 =x

The bottom is 2x-3 = 2*7-3 = 14-3 = 11

The median is 4x-16 = 4*7-16 = 28 -16 = 12
