Answer:

[tex]c = 25[/tex]

Step-by-step explanation:

Vertex of a quadratic function:

Suppose we have a quadratic function in the following format:

[tex]f(x) = ax^{2} + bx + c[/tex]

It's vertex is the point [tex](x_{v}, y_{v})[/tex]

In which

[tex]x_{v} = -\frac{b}{2a}[/tex]

[tex]y_{v} = -\frac{\Delta}{4a}[/tex]

Where

[tex]\Delta = b^2-4ac[/tex]

If a>0, the vertex is a minumum point, that is, the minimum value happens at [tex]x_{v}[/tex], and it's value is [tex]y_{v}[/tex].

In this question:

[tex]a = 1[/tex]

Minimum value at [tex]x = 4[/tex] means that [tex]x_v = 4[/tex]. So

[tex]x_{v} = -\frac{b}{2a}[/tex]

[tex]4 = -\frac{b}{2}[/tex]

[tex]b = -8[/tex]

So

[tex]f(x) = x^2 - 8x + c[/tex]

Minimum value of 9:

[tex]y_v = 9[/tex]

So

[tex]y_{v} = -\frac{\Delta}{4a}[/tex]

[tex]9 = -\frac{\Delta}{4}[/tex]

[tex]-\Delta = 36[/tex]

[tex]\Delta = -36[/tex]

[tex]b^2 - 4ac = -36[/tex]

[tex](-8)^2 - 4c = -36[/tex]

[tex]-4c = -100[/tex]

[tex]4c = 100[/tex]

[tex]c = \frac{100}{4}[/tex]

[tex]c = 25[/tex]

I cannot quite show this to you, but the coordinates are listed below. If you want to know how you would answer this type of question, read the following. The question is indicating that you must translate. This means to move the figure however many units. In this question, it says 5 units to the right and 4 units down. You would take the bolded point and drag it 5 to the right. Then, from that point, drag it 4 units down.

Point in original: (-7,3)

Point in final figure:(-2,-2)

Answer:

It takes you together 6.67 minutes to paint 50 square feet, as you have to consider that the together rate is the sum of the separate rates.

Step-by-step explanation:

The together rate is the sum of the separate rates.

In this question:

Sam's rate is 1/10 for 25 square feet, so 1/20 for 50 square feet.

Your's rate is 1/5 for 25 square feet, so 1/10 for 50 square feet.

Together rate:

[tex]\frac{1}{x} = \frac{1}{20} + \frac{1}{10}[/tex]

[tex]\frac{1}{x} = \frac{1}{20} + \frac{2}{20}[/tex]

[tex]\frac{1}{x} = \frac{3}{20}[/tex]

[tex]3x = 20[/tex]

[tex]x = \frac{20}{3} = 6.67[/tex]

It takes you together 6.67 minutes to paint 50 square feet, as you have to consider that the together rate is the sum of the separate rates.

Answer: (D) The small p-value suggests that there is evidence of an association between category and opinion about the use of instant replay.

Step-by-step explanation:

From the P-value supplied, it shows that the researcher was 99% confident of the experiment and have 1% chance of error.

Given that the p-value less than 0.001 were calculated, it translates that there is a statistical dependency between the category of the people interviewed and opinion about the use of instant replay.

Answer:

Gross margin= $50

Step-by-step explanation:

Giving the following information:

Selling price= $264

Unitary cost= $214

To calculate the gross margin, we need to deduct from the selling price the unitary cost:

Gross margin= selling price - unitary cost

Gross margin= 264 - 214

Gross margin= $50

Answer:

50 days are needed to make $2500.

Step-by-step explanation:

Number of tons per day:

One ton equals 2000 pounds, as the problem states as a hint.

The company collects 200 pounds per day.

1 ton - 2000 pounds

x tons - 200 pounds

2000x = 200

x = 200/2000

x = 0.1

0.1 tons per day.

A recycling company makes $500 per ton of aluminum scrap collected.

0.1*500 = $50 per day.

How many days are needed to make $2500?

1 day - $50

x days - $2500

50x = 2500

x = 250/5

x = 50

50 days are needed to make $2500.

Answer:

[tex]\frac{1}{21} = 0.0476[/tex] probability that both marbles are red.

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

Find the probability that both of the selected marbles are red

First marble: 2 red from a set of 5 + 2 = 7

Second marble: 1 red from a set of 6.

So

[tex]p = \frac{2}{7}*\frac{1}{6} = \frac{2}{42} = \frac{1}{21} = 0.0476[/tex]

[tex]\frac{1}{21} = 0.0476[/tex] probability that both marbles are red.

The height of the rectangular sculpture is h = ( 20/21 ) feet

The volume of the rectangle is given by the product of the length of the rectangle and the width of the rectangle and the height of the rectangle

Volume of Rectangle = Length x Width x Height

Volume of Rectangle = Area of Rectangle x Height

Given data ,

Let the volume of the rectangular sculpture be V

Now , the value of V = ( 16/21 ) feet³

And , the base area of the rectangular sculpture B = ( 4/5 ) feet²

Volume of Rectangle = Area of Rectangle x Height

On simplifying , we get

The height of the sculpture h = ( 16/21 ) feet³ / ( 4/5 ) feet²

The height of the sculpture h = ( 20/21 ) feet

Therefore , the value of h is ( 20/21 ) feet

Hence , the height of the sculpture is ( 20/21 ) feet

Answer:

option#1 y = -√x + 2

Step-by-step explanation:

---------

The equation that represents the transformation function is: y = -√x+2

A Transformation in Math is a process of moving an object (two-dimensional shape) from its original position to a new position.

Given that,  a parent function f(x) = √x,

Now, this function f(x) is transformed to get a function whose graph is given.

Let the transformed function is: g(x)

Clearly by looking at the graph we observe that at x=4 we have:

g(x)=0

1) y = -√x+2

at x = 4

y = -√4+2

y = 0 [correct]

Hence, the equation that represents the transformation function is: y = -√x+2

The value of t on solving the equations r + t = r and r − t = − s is 0 and s + r so, option C is correct.

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side. It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Given:

r + t = r and r − t = − s

Calculate the value of t  as shown below,

t = r - r   (Transform the equation as shown)

t = 0

-t = -s - r

t = s + r

Thus, the value of t can be 0 and s + r.
