If a = 2 + i, and b = 3 – 2i, whats b/a?

1 answer:

3 0

Hello :
<span>b/a = (3-2i)/(2+i)
= </span>(3-2i)(2-i)/(2+i)(2-i)
= (3-2i)(2-i)/(2²-i²) .......i² = -1
= (6-3i-4i -2)/5
=(4 -7i)/5
b/a = (4/5)-(7/5) i

The number of seats in each row of a theater forms an arithmetic sequence. The fifth row contains 22 seats. The tenth row contai

beks73 [17]

Let $s_n$ denote the number of seats in the $n$ -th row. $s_n$ is arithmetic, so

$s_n=s_{n-1}+d$

for some constant $d$ .

We're told $s_5=22$ and $s_{10}=37$ , so that

$s_{10}=s_9+d$

$s_{10}=(s_8+d)+d=s_8+2d$

$s_{10}=(s_7+d)+2d=s_7+3d$

and so on up to

$s_{10}=s_5+5d\implies37=22+5d\implies5d=15\implies d=3$

The pattern continues:

$s_5=s_4+3$

$s_5=(s_3+3)+3=s_3+2\cdot3$

and so on up to

$s_5=s_1+4\cdot3\implies22=s_1+12\implies\boxed{s_1=10}$

Knowing that you need a sample pool of 1019 students to ultimately get about 500 students in your sample, you are in a position

Allushta [10]

Answer:

Sampling interval = 9.323

Step-by-step explanation:

Given that:

Population size, N = 9500

Require sample, n = 1019

Sampling interval :

Population size / required sample size

Sampling interval = 9500 / 1019 = 9.3228

Interpretation :

In other to obtain a sample of 1019 drawn systematically from the population, a sample will be drawn at every 9.323 units from the population of 9500

Tresset [83]

Answer:

It is 7

y is the total cost.

x is the number of hours.

b : that's 16 dollars.

y = 9x+16

The problem states that the cost was 79 dollars.

Substitute that for y and solve for x.

79 = 9x+16

63 = 9x
