Hello can someone help me please..?

Answer:

Step-by-step explanation:

Rewrite the equation

Start multiplying

Simplify

The value of ab³ in simplified form is equal to -250(i + 1).

Equations are mathematical expressions that have two algebras on either side of an equal (=) sign. The expressions on the left and right are shown to be equal, demonstrating this relationship. L.H.S. = R.H.S. (left-hand side = right side) is a fundamental simple equation. For an unknown quantity represented by an unknown variable, equations are then solved to determine its value. A statement is not even an equation if there is no "equal to" sign in it.

From the given values in the question,

a = -2 + 2i

b = -5i

ab³ = (-2 + 2i) × (-5 i)³

=  (-2 + 2i) (-125 i³)

=  (-2 + 2i) (-125 (-i))

=  (-2 + 2i) (+125 i)

= 125 i(-2) + 125 i(2i)

= -250 i + 250 i²

= -250 i -250 or,

ab³ = -250 (i+1)

Answer:

The Interquartile range is 188

Step-by-step explanation:

Missing Data:

1,19,35,43,49,55,63,94,105,110,175,231,239,351,738

Required

Determine the Interquartile range (IQR)

The given data is ordered already.

First, we need to determine the median

For odd number of data

Median = ½(n + 1)th

In this case, n = 15; so

Median = ½(15 + 1)th

Median = ½(16)th

Median = 8th

This implies that the median is at the 8th position.

So, we have:

1,19,35,43,49,55,63 ----> Lower

(94) ---- Median

105,110,175,231,239,351,738 ---- Upper

Next, we determine the median of the lower and upper sets.

These are called lower quartile (Q1) and upper quartile (Q3) respectively

Lower: 1,19,35,43,49,55,63

Number of data, n = 7

Q1 = ½(n + 1)th

Q1 = ½(7 + 1)th

Q1 = ½(8)th

Q1 = 4th position

From the list of data in the lower set,

Q1 = 43

Upper: 105,110,175,231,239,351,738

Number of data, n = 7

Q3 = ½(n + 1)th

Q3 = ½(7 + 1)th

Q3 = ½(8)th

Q3 = 4th position

From the list of data in the upper set,

Q3 = 231

IQR is then calculated as thus:

IQR = Q3 - Q1

IQR = 231 - 43

IQR = 188

Answer:

y = 1 -5x

Step-by-step explanation:

You have to get y by itself. So first you move 5x to the other side but since it’s positive you have to make it negative so it canceled out.

Hi there!

[tex]\large\boxed{y = -5x + 1}[/tex]

5x + y = 1

Arrange into slope-intercept form (y = mx + b):

Subtract both sides by -5x to isolate y:

5x - 5x + y = 1 - 5x

y = 1 - 5x

Rearrange:

y = -5x + 1

Graph the equation by finding corresponding x and y values:

                    X                               Y

                    0                                1

                    1                                -4

                    2                                -9

                    -1                                 6

                    -2                                11

Answer:

x = [tex]\frac{7}{2}[/tex]

Step-by-step explanation:

Given

2x + 5 = 12 ( subtract 5 from both sides )

2x = 7 ( divide both sides by 2 )

x = [tex]\frac{7}{2}[/tex] [ or x = 3.5 ]

Answer:

f=7/4

Step-by-step explanation:

substitute x for 4 and do the equation you will get the equation f(4)=1/2(4)+5 simplify to the equation to 4f=2+5. Then do the addition and get 4f=7. Divide both sides by 4 and get f=7/4

A)

Sequence: 1 , 8 , 15 , 22 , 29

Difference : 7

A sequence is an ordered list of elements with a specific pattern.

The nth term of the sequence:

A) 1  8  15  22  29 is [tex](n-1)^{th}[/tex] + 7.

B) 12  16  20  24  28 is [tex](n-1)^{th}[/tex] + 4.

A sequence is an ordered list of elements with a specific pattern.

Example: 2, 5, 8, 11, ... is a sequence where each term is obtained by adding 3 to its previous term.

We have,

a) 1  8  15  22  29

1 + 7 = 8

8 + 7 = 15

15 + 7 = 22

22 + 7 = 29

We see that each term is obtained by adding 7 to the previous term

So, the nth will be in the form:

nth = [tex](n-1)^{th}[/tex] + 7

b) 12  16  20  24  28

12 + 4 = 16

16 + 4 = 20

20 + 4 = 24

2 + 4 = 28

We see that each term is obtained by adding 4 to the previous term.

So, the nth term will be in the form:

nth = [tex](n-1)^{th}[/tex] + 4

Thus the nth term of the sequence:

1  8  15  22  29 is [tex](n-1)^{th}[/tex] + 7.

12  16  20  24  28 is [tex](n-1)^{th}[/tex] + 4.

Answer:

B.

Step-by-step explanation:

Answer:

$177

Step-by-step explanation:

Given that:

Percentage covered by policy = 70%

Hence, person needs to pay (100 - 70)% = 30%

X - Ray cost :

1st = 640

2nd = 950

Total cost = (640 + 950) = 1590

Amount the person has to pay:

Total cost * 30%

1590 * 0.3 = $477

Since the person has $300 deductible :

$477 - $300 = $177

Answer:

M<2= 65

Step-by-step explanation:

The reason it is 65 because 2 angles add up to either 90 or 180 and in this case it would be 180.

You would use angle addition postulate to find the answer so M<1 + M<2 = 180.

Since M<1 is 115 you would substitute it into the formula so 115 + M<2 = 180

Then you would subtract 115 from 180 in which you would get M<2 = 65
