Simplify the given expression below: (2 points) 2 divided by the quantity of 2 plus 5i

Answers

Answer 1

Answer: The given expression "2 divided by the quantity of 2 plus 5i" can be translated as 2/(2+5i). Simplifying expressions aim is to simplify it into its simplest form. Since i = √-1 substitute it into the expression.

2/(2+5√-1)

then multiply it by 2-5√-1 on the numerator and denominator and we have

[2(2 - 5√-1)] / [4 - 25(1)]

(4-10√-1)/(-21)

On the first night, the Movie House Theater sold 7 adult tickets and 11 child tickets for
$227. On the second night they took in $150 by selling 6 adult tickets and 6 child tickets.
Find the price of an adult ticket and the price of a child ticket.

Answers

Answer:

Adults $10

Child: $6

Step-by-step explanation:

I took the test

The price of an adult ticket and the price of a child ticket are $12 and $13.

What is the system of equation?

One or many equations having the same number of unknowns that can be solved simultaneously called as simultaneous equation. And simultaneous equation is the system of equation.

Given:

On the first night,

the Movie House Theater sold 7 adult tickets and 11 child tickets for $227.

On the second night, they took in $150 by selling 6 adult tickets and 6 child tickets.

Let x be the number of tickets sold to an adult and y be the number of tickets sold to a child.

According to the question,

7x + 11y = 227   equation 1

and 6x + 6y = 150,

Simplifying,

x + y = 25   equation 2

Now, we have a system of equations.

7x + 11y = 227   equation 1

x + y = 25   equation 2

From the equation 2 we have,

y = 25 - x

Substitute the value of y to the equation 1,

7x + 11(25-x) = 227

7x + 275 - 11x  = 227

275 - 227 = 4x

x = 48/4

x = 12

Then y = 25 - 12

y = 13.

Therefore, the prices of ticket for adult's and children are $12 and $13 respectively.

Find the length of MN.

*LOOK AT PICTURE*

Answers

Answer:

MN = 10

Step-by-step explanation:

There is a scale factor of 2 [This means that the lengths of triangle ∆MPN are exactly 2 times larger than ∆SRQ], so 5 × 2 = 10.

Notice that each corresponding line is marked by a black mark perpendicular to the side. Since 2 corresponds to 4, and 3 corresponds to 6, 5 must correspond to 10. These triangles are similar as indicated by the marks so there is just a size difference. Because these two triangles are similar, the sides must be proportional.

∆MPN ~ ∆SRQ.

It can also be thought of as completing a set of proportional fractions:

4/2 = 6/3 = ?/5

4/2 = 2 → 6/3 = 2 → ?/5 = 2.

?/5 = 2, ? = 5 × 2 = 10.

Which of the following is the correct five-number summary?

22, 24, 26, 28, 29
23, 24.5, 26, 28, 29
22, 24, 27, 28, 30
22, 24.5, 26, 28, 30

Answers

Given:

The data values are 22, 23, 23, 24, 24, 24, 25, 25, 25, 25, 26, 26, 26, 26, 26, 27, 27, 27, 28, 28, 28, 28, 29, 29, 30.

To find:

The five-number summary.

Solution:

We have,

22, 23, 23, 24, 24, 24, 25, 25, 25, 25, 26, 26, 26, 26, 26, 27, 27, 27, 28, 28, 28, 28, 29, 29, 30

Divide the data values on 2 equal parts.

(22, 23, 23, 24, 24, 24, 25, 25, 25, 25, 26, 26), 26, (26, 26, 27, 27, 27, 28, 28, 28, 28, 29, 29, 30)

Divide each parentheses in two equal parts.

(22, 23, 23, 24, 24, 24), (25, 25, 25, 25, 26, 26), 26, (26, 26, 27, 27, 27, 28), (28, 28, 28, 29, 29, 30)

Now,

Minimum value = 22

[tex]Q_1=\dfrac{24+25}{2}=24.5[/tex]

Median = 26

[tex]Q_2=\dfrac{28+28}{2}=28[/tex]

Maximum value = 30

So, the five number summary is 22, 24.5, 26, 28, 30.

Therefore, the correct option is D.

find the first 5 terms in the sequence
A) 6, 12, 24, 48, 96
B)1, 2, 3, 4, 5
C)6, 7, 8, 9, 10
D) 6, 11, 21, 41, 81

Answers

Answer:

The first five terms are 6, 11, 21, 41, 81 ⇒ D

Step-by-step explanation:

∵ The rule of the sequence is a(1) = 6; a(n) = 2 a(n - 1) - 1 for n ≥ 2

∴ The first term of the sequence is 6

∴ The value of n represents the position of the term

∵ n = 2

∴ a (n - 1) = a(2 - 1) = a1

∵ a1 = 6

→ Substitute a1 by 6

∴ a(2) = 2(6) - 1 = 12 - 1

a(2) = 11

∵ n = 3

∴ a (n - 1) = a(3 - 1) = a2

∵ a2 = 11

→ Substitute a2 by 11

∴ a(3) = 2(11) - 1 = 22 - 1

a(3) = 21

∵ n = 4

∴ a (n - 1) = a(4 - 1) = a3

∵ a3 = 21

→ Substitute a3 by 21

∴ a(4) = 2(21) - 1 = 42 - 1

a(4) = 41

∵ n = 5

∴ a (n - 1) = a(5 - 1) = a4

∵ a4 = 41

→ Substitute a4 by 41

∴ a(5) = 2(41) - 1 = 82 - 1

a(5) = 81

∴ The first five terms are 6, 11, 21, 41, 81

What will the amount of money be when the total amount of money paid to both gyms is the same?

Answers

Answer:

Step-by-step explanation:

Community gym

=> membership fee = $50

=> monthly fee = $55

=> First month = 105$

=> 50 + 55(x)

=> 50 + 55 (15)

=> 50 + 825

=> 875

Workout gym

=> membership fee = $200

=> monthly fee = $45

=> First month = 245$

=> 200 + 45(x)

=> 200 + 45(15)

=> 200 + 675

=> 875

On the 15th month, community gym and workout gym will both get the same amount of $875.
