Answer:

I believe that it would just be 20% of the $45 which would mean that you would have to pay $36 a month.

Hope this is helpful!

The cost to you per month, after the landlord's contribution, is $36.

If you buy both Liability and Contents insurance, and take advantage of the landlord's offer to pay 20% of the cost, the cost to you per month can be calculated as follows:

Let's assume the cost of Liability insurance is represented by 'L' and the cost of Contents insurance is represented by 'C'.

According to the information given, if you buy both insurances at the same time, the cost is $45 per month.

This means: L + C = $45

The landlord is willing to pay 20% of the cost, which is equal to 20% of ($45). To calculate this amount:

20% of $45 = (20/100) x $45 = $9

So, the landlord will pay $9 towards the cost of both insurances.

Now, if you subtract the landlord's contribution from the total cost, you'll get the amount you have to pay:

(L + C) - $9 = $45 - $9 = $36

Therefore, the cost to you per month, after the landlord's contribution, is $36.

Answer:

Step-by-step explanation:

|x-4|<13.

The above equation means, whatever the actual value of x is, the value of (x - 4) must be greater than - 13 and less than 13.

Hence, -13 < x - 4 < 13 or, -9 < x < 17. The value of x will be in between -9 and 17. The value of x can not be -9 or 17.

Answer:

The correct answer is A. x = 2 +/- √42

Step-by-step explanation:

Let's solve for x the quadratic equation, this way:

x² - 4x - 9 = 29

x² - 4x - 38 = 0

Using the quadratic formula, we have:

x = [- (-4) +/- √ -4² - 4 * -38]/2

x = 4 +/- √ 16 + 152/2

x = 4 +/- √ 168/2

x = 4 +/- √ 4 * 42/2

x = 4 +/- 2 √42/2

x = 2 +/- √42

The correct answer is A. x = 2 +/- √42

Final answer:

To find the final cost of an Apple iPod after a mail-in rebate and the cost of mailing the rebate (envelope and stamp), subtract the rebate amount from the original price and add the mailing costs. The total cost after these calculations is $726.82.

Explanation:

Let's tackle the Apple iPod rebate calculation problem. An Apple iPod sells for $781.29 and has a mail-in rebate for $55.00. To calculate the cost after the rebate, you must also consider the costs of an envelope and a stamp, which are $0.13 and $0.40, respectively. The formula for the final cost after applying the mail-in rebate, including the expenses for an envelope and a stamp, is as follows:

Calculate the rebate price by subtracting the rebate amount from the original price: $781.29 - $55.00 = $726.29.

Add the costs of the envelope and stamp to the price after rebate: $726.29 + $0.13 + $0.40 = $726.82.

The final cost of the iPod after the rebate and additional costs is $726.82.

Answer:

(- 2, - 3 )

Step-by-step explanation:

Given the endpoints of a segment (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is

[0.5(x₁ + x₂), 0.5(y₁ + y₂ ) ]

Here (x₁, y₁ ) = (2, 3) and (x₂, y₂ ) = (x, y) and the midpoint = (0, 0), thus

0.5(2 + x) = 0 , that is

2 + x = 0 ( subtract 2 from both sides )

x = - 2

0.5(3 + y) = 0, that is

3 + y = 0 ( subtract 3 from both sides )

y = - 3

Thus (x, y) = (- 2, - 3 )

Given :

y = [tex]\frac{1}{2}[/tex][tex](x-3)^{2}[/tex] - 6

comparing with the standard form :

y = a[tex](x-h)^{2}[/tex] + k

vertex = ( h , k )

Focus = (h , k+14a )

Directrix = y = k

Vertex = ( 3 , -6 )

Focus = ( 3 , -6+14{1/2} )

Focus = ( 3 , 1)

Directrix ⇒ y = -6

(19)

[tex]x^{2}[/tex] + [tex]4y^{2}[/tex] = 13 .............. equation 1

[tex]x^{2}[/tex] - [tex]4y^{2}[/tex] = 5  ..................... equation 2

Answer:

54.

Step-by-step explanation:

Start at 60 and subtract 6. That leaves you with 54.

The 60th term in the arithmetic sequence -6, -3, 0, 3, ... can be determined using the formula of an arithmetic sequence, which results in a value of 171.

An arithmetic sequence, also known as an , is a sequence of numbers in which each term is obtained by adding a fixed constant to the previous term. In simpler terms, it's a sequence where the difference between any two consecutive terms is always the same.

The given sequence is an arithmetic progression where each term differs from the previous term by a constant value. In this case, the common difference[tex](\(d\))[/tex]between consecutive terms is 3.

To find the 60th term of this sequence, we can use the formula for the nth term of an arithmetic sequence:

[tex]\[a_n = a_1 + (n - 1) \cdot d\][/tex]

Here,[tex]\(a_n\)[/tex]represents the nth term, \(a_1\) is the first term, \(n\) is the term number we want to find, and \(d\) is the common difference.

In this sequence:

- The first term [tex](\(a_1\)) is -6.[/tex]

- The common difference [tex](\(d\)) is 3.[/tex]

- We want to find the 60th term, so [tex]\(n = 60\).\\[/tex]

Now, we can substitute these values into the formula:

[tex]\[a_{60} = -6 + (60 - 1) \cdot 3\][/tex]

[tex]\[a_{60} = -6 + 59 \cdot 3\][/tex]

[tex]\[a_{60} = -6 + 177\][/tex]

[tex]\[a_{60} = 171\][/tex]

Therefore, the 60th term in this arithmetic sequence is 171. This means that if you continued the sequence, the 60th term would be 171 units greater than the first term (-6), following the pattern of adding 3 at each step.
