Can you show that this quadrilateral is a parallelogram

Step-by-step explanation:

for a function every valid x value must have exactly 1 y value. several x values can have the same y value assigned but never can a x value have multiple y values assigned.

the valid x values for m are -3. -2, -1, 1, 2, 3.

and indeed, every one of these values has exactly one y value out of the possible 1, 4, 9 values.

so, m is a function.

but the inverse function turns the meaning of x and y upside-down. x becomes y and y becomes x.

and now we see that for the inverse the x value of 1 has two assigned y values (-1, 1).

the same for 4 (-2, 2) and 9 (-3, 3).

so, the inverse is NOT a function.

Answer:

20%

Step-by-step explanation:

$34 - $27.20 = $6.80

[tex]\frac{6.80}{34} = 0.2[/tex]

0.2 x 100 = 20%

:]

The percent of discount in the tag is, 20%.

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

Given that;

The price on the tag was $34, but Mia paid $27.20 before tax.

Here, The discount price = $34 - $27.20

                                       = $6.8

Hence, The percent discount = 6.8 / 34 × 100

                                              = 20%

So, what you do is plug in some points.

Let's try x = 0.

f(x) =  3[tex]\sqrt{0}[/tex] - 2 = -2

First point is (0,-2)

There is only one graph with this point at that is the last graph.

Step-by-step explanation:

it must have 2 solutions, as the absolute value makes negative and positive values equal.

so, 2 approaches : positive and negative.

1. positive

(x + 2) + 4 = 11

x + 6 = 11

x = 5

2. negative

-(x + 2) + 4 = 11

-x - 2 + 4 = 11

-x + 2 = 11

-x = 9

x = -9

The purchase price of Wynona’s boots is 85.5% of the original price.

It is given that

The marked price of boots = $85.79

The percentage is a relative value indicating the hundredth parts of any quantity.

Price after a discount of 10% = [tex]85.79 - 85.79*10/100 = 77.211[/tex]

Price after another discount of 5% = [tex]77.211-77.211*5/100 = 73.35[/tex]

[tex]\frac{PurchasePrice}{OriginalPrice}*100 =\frac{73.35}{85.79}*100 = 85.5[/tex]

Therefore, The purchase price of Wynona’s boots is 85.5% of the original price.

Step-by-step explanation:

Let the cupcake cost = c

Let the milkshake cost = m

4c + 3 m = 23

2c + 4m = 24        multiply this equation by 2

2(2c + 4m = 24)

4c + 8m =     48        Now put the first equation underneath this one

4c + 3m = 23       Subtract

       5m = 25         Divide by 5

        m = 25/5

         m = 5

Use 2c + 4m = 24

m = 5

2c + 4*5 = 24            Combine

2c + 20 = 24             Subtract 20 from both sides

2c = 24 - 20

2c = 4                        Divide by 2

c = 4/2

c = 2

The formula that describes this function is c = 50t + 200

A linear equation is in the form:

y = mx + b

Where y,x are variables, m is the rate of change  and b is the y intercept.

Let c represent the distance june has traveled after time t.

Since the cities are 200 miles apart, hence b = 200. Also the spoeed is 50 mph, hence m = 50:

Answer:

Step-by-step explanation:

a. The determination of the break-even number of subscribers for Star Stream is as follows:

Break-even number of subscribers = Fixed Costs/Contribution Margin per subscriber

= 35,294,118 ($3,000,000,000/$85)

b. If Star Stream increases the annual content costs to $2,600,000,000, the break-even number of subscribers will increase to 42,352,941 subscribers.

= 42,352,941 ($3,600,000,000/$85)

c. The annual subscription needs to increase from $120 to $142 to maintain the same break-even as in (a).

The break-even analysis is a financial tool for determining the price level at which the total revenue equals the total costs (variable and fixed).

Using the break-even analysis model, one can determine the number of units to sell so that fixed costs are recovered.

Server lease costs per year = $100,000,000

Content costs per year = $2,000,000,000

Fixed operating costs per year = $900,000,000

Total fixed costs per year = $3,000,000,000

Bandwidth costs per subscriber per year = $15

Variable operating costs per subscriber per year = $25

Subscription per year = $125

Contribution margin per subscriber per year = $85 ($125 - $15 - $25)

Contribution margin ratio = 68% ($85/$125 x 100)

a. Determine the break-even number of subscribers.

b. Assume Star Stream planned to increase available programming and thus increase the annual content costs to $2,600,000,000. What impact would this change have on the break-even number of subscribers?

c. Assume the same content cost scenario in (b). How much would the annual subscription need to change to maintain the same break-even as in (a)?

Thus, with an annual subscription of $142, the variable cost of $40 per subscriber per year, contribution margin of $102 ($142 - $40), and a total fixed cost of $3,600,000,000, the break-even number of subscribers will remain 35,294,118 ($3,600,000,000/$102).

Step-by-step explanation:

The magnitude of an earthquake that is 35 times more intense than a standard earthquake is 1.5.

The magnitude of an earthquake is the measured of the amplitude r the size of the seismic waves which is produced by the earthquake.

The magnitude, m, of an earthquake is defined to be

[tex]m = \log\left( \dfrac{I}{S}\right)[/tex]

Here (I) is the intensity of the earthquake (measured by the amplitude of the seismograph wave) and (S) is the intensity of a "standard" earthquake, which is barely detectable.

The magnitude of an earthquake that is 35 times more intense than a standard earthquake has to be find out. The Intensity of this earth quack can be given as,

[tex]I=35S[/tex]

Put this values in the above formula as,

[tex]m = \log\left( \dfrac{35 S}{S}\right)\\m = \log\left( 35 \right)\\m\approx 1.5[/tex]

Thus, the magnitude of an earthquake that is 35 times more intense than a standard earthquake is 1.5.
