What is the distance between 4-i and -2+3i?

stepan [7]

If you're working with complex numbers, then I'm sure you're comfortable with plotting them on a complex-plane ... real part of the number along the x-axis, and imaginary part of the number along the y-axis.

When you look at it that way, your two points are simply two points on the x-y plane:

   4 - i    ===> (4, -1)

   -2 + 3i ===> (-2, 3) .

The distance between them is

   D = √ (difference in 'x')² + (difference in 'y')²

   = √ (6)² + (4)²

   = √ (36 + 16)

   = √ (52)

   =    7.211 (rounded)

The ratio of band students to choir students is 4:6. There are a total of 60 students in the band and choir. How many students a

xenn [34]

Answer:

24

Step-by-step explanation:

Given that:

The ratio of band students to choir students is 4 : 6.

Total number of students in the band and choir combined = 60

To find:

The number of students in the band = ?

Solution:

First of all, let us understand the meaning of the ratio given.

Ratio of 4 : 6 means there are 4 number of band students for every 6 number of choir students.

Also, number of band students will be in the multiples of 4 only and

number of choir students will be in the multiples of 6 only

Let the total number of band students = 4 $x$

Let the total number of choir students = 6 $x$

Total number of students = 60

As per question statement, we can write the following equation:

$\Rightarrow 4x+6x=60\\\Rightarrow 10x = 60\\\Rightarrow x =6$

Total number of band students = 4 $\times$ 6 = <em>24</em>

A statue in the park is 24 feet tall and has a width of 36 inches. Chase was in

NeTakaya

Answer:

<u>22.33 feet tall / 267.96 inches tall</u>

Step-by-step explanation:

The statue is 36 inches wide. If Chase made his model of the statue 16 inches wide, he decreased it by 20 inches. Now change the inches into feet. 36 inches would be 3 feet, 16 inches would be 1.33 feet and 20 inches would be 1.67 feet. <u>24ft - 1.67 = 22.33ft.</u> Now change the answers to inches. 22.33ft will be 267.96 inches tall.
