Answer:

12.5

Step-by-step explanation:

Vetrx is at: (0,-1) because other y values are repeated

y = a(x - 0)² - 1

y = ax² - 1

Using (1,0.5)

0.5 = a(1)² - 1

a = 1.5

f(x) = 1.5x² - 1

f(-3) = 1.5(-3)² - 1

The arc length of PQ is 9.42 inches.

Answer:

The comparison using median and IQR is best because one of the graphs is not symmetrical.

Step-by-step explanation:

The following information is missing

A box plot titled Number of Minutes Women Spend on Breaks. The number line goes from 30 to 70. The whiskers range from 30 to 54, and the box ranges from 34 to 50. A line divides the box at 48.  

A box plot titled Number of Minutes Men Spend on Breaks. The number line goes from 30 to 70. The whiskers range from 30 to 68, and the box ranges from 36 to 60. A line divides the box at 48.  

The business owner uses the median and IQR to determine the center and variability of the data sets. Which best describes the comparison?

The comparison would be more accurate using the mean and MAD because one of the graphs is symmetric.

The comparison would be more accurate using the mean and MAD because the median of both data sets is the same.

The comparison using median and IQR is best because one of the graphs is not symmetrical.

The comparison using median and IQR is best because the median is greater than the IQR for both data sets.

Mean and MAD are useful for comparison when both data sets are symmetrical.

In the women box plot the Q1 is at 34, the median is at 48, and the Q3 is at 50, so it is not symmetrical (the difference between the median and the Q1, and the Q3 and the median is not the same)

Answer:

Step-by-step explanation:

Point D (3,1); Point B (-1,-2); Point C (4, -2)

Point D lies on the circle whose center is Point B and which contains the Point C if the distance:

BD = BC

BD^2 = BC^2

(- 1 - 3)^2 + (- 2 - 1)^2 = (4 - (-1))^2 + (-2 - (-2))^2

16 + 9 = 25

25 = 25

Follows, point D lies on the circle with radii 5.

To solve graphically we first need to write the equation of the circle whose center is Point B and which contains the Point C:

(x - (-1))^2 + (y - (-2))^2 = 5^2

(x + 1)^2 + (y + 2)^2 = 5^2

Answer:

x = 1 and

Y = 2

Step-by-step explanation:

1. Y = x + 1

2. X + Y = 3

Substitute equation 1 into equation 2

X + Y = 3

X + X + 1 = 3

2x + 1 = 3

Subtract 1 from both sides to eliminate 1 on the left side

2x + 1 - 1 = 3 - 1

2x = 2

Divide both sides by 2 to isolate x

2x/2 = 2/2

x = 1

Substitute 1 for x in either equation to get Y

Using equation one, we have

Y = x + 1

= 1 + 1

= 2

x = 1

Y = 2

Check

X + Y = 3

1 + 2 = 3

3 = 3

Answer:

119 student tickets and 95 non-student tickets

Step-by-step explanation:

I did a trial-and-error solution.

I started with 107 students and 107 non-students:

(107*$7)+(107*$12) = $2033

It was too high, which tells us that there should be more who paid for the cheaper price.

I ended up with 119 and 95:

(119*$7)+(95*$12) = $1973

Answer:

Sample Response: Partial and negative tickets cannot be sold, so the minimum number values of e and s are 0. If s = 0, then e = 16, and if e = 0, then s = 20. Therefore, the values of s are whole numbers from 0 to 20 and the values of e are whole numbers between 0 and 16. The greatest number of student tickets sold was 20 and the greatest number of nonstudent tickets sold was 16.

Answer:

I think the graph that best matches the discription is option D (so the last one)

A graph representing this coffee shop chain's sales would likely resemble a 'W', with two significant turning points, never declining below $250,000, and a general upward trend indicating sales are expected to increase.

In Mathematics, when we discuss turning points, we generally refer to the points on a graph where the curve changes direction. If sales are increasing in the long run and there have been two 'turning points' this year, the graph should generally showcase a positive upward trend, dips at the points of turning, and then subsequent increases. Given that the least amount of sales during the year is about $250,000, the graph should never fall below this point.

In this context, the turning points would reflect changes in sales - a drop followed by a rise. It’s important to note that without the exact data or the graph, I cannot definitively identify it. However, considering the given descriptive data, we can deduce that the graph might look somewhat like a 'W', with the middle point not declining below $250,000 and a general upward trend.

Answer:

Step-by-step explanation:

To determine the correct standard form of a quadratic equation from the given options, we expand (x-3)2 to get [tex]x^2 - 6x + 9 = 0,[/tex] which is the correct standard form [tex]ax^2 + bx + c = 0.[/tex]

To write the quadratic equation in standard form, you need to remember that the standard form is ax2 + bx + c = 0. The given equations will be compared to this standard form to find the correct answer.

Given Equations:

(x-3)2=0

0x2+9=0

0x2+6x+9=0

0x2 - 6x +9=0

Only the first equation, (x-3)2=0, can be simplified to the standard quadratic form if expanded. Let's expand it:

(x-3)2 = x2 - 6x + 9

So the correct standard form of the given equation is x2 - 6x + 9 = 0.

The other options, due to having a coefficient of 0 for x2, are not proper quadratic equations as they do not have the quadratic term.

Answer:

{1, 3, 5, 7, 9, 11}

The sample space of the odd number will be (1, 3, 5, 7, 9, 11).

Sample space simply means the possible outcomes that we can get when we make an experiment.

Odd numbers cannot be divided by 2. Examples include 1, 9, 11, 23, 45, 75 etc. In this case, the odd numbers that we can get from 1 to 11 will be 1, 3, 5, 7, 9 and 11 and this will be the sample space.

In conclusion, the sample space will be (1, 3, 5, 7, 9, 11)

Domain: All Real numbers

Range : { f{x) | f(x) [tex]\leq[/tex] 0, f(x) = 1 }

Step-by-step explanation:

The domain consists of all Real numbers (notice that you have a well defined f(x) value for all possible x on the horizontal axis.

The Range is associated with the set of those f(x) values (on the vertical axis) that are connected via the functional relationship with a value  "x" of the domain. The line with positive slope extends to all f(x) values that are [tex]\leq[/tex] 0 (smaller than or equal to zero). While the flat horizontal line on the right of the plot corresponds to the line f(x) =1 (only one value of f(x) [1} connects with the x-values of the Domain that are larger than 3.

The shadow length of Kyle is 1.2 feet,if a lighthouse is 150 feet tall and cast a shadow of 30 feet. Kyle is standing next to a lighthouse and is 6 feet tall.

Step-by-step explanation:

The given is,

                  A lighthouse is 150 feet tall.

                  Cast a shadow of 30 feet.

                  Kyle is 6 feet tall.

Step:1

                 Ref the attachment,

                 From triangle ABC,

                               tan ∅ = [tex]\frac{Opp}{Adj}[/tex]......................(1)

                 Where, Opp = AB = 150 feet

                                Adj = BC = 30 feet

                 Equation (1) becomes,

                              tan ∅ = [tex]\frac{150}{30}[/tex]

                                        = 5

                                     ∅ = [tex]tan^{-1}[/tex] 5

                                     ∅ = 78.69°

                 ∅ is same for both ABC and PQR triangle.

                 From triangle PQR,

                               tan ∅ = [tex]\frac{Opp}{Adj}[/tex]......................(1)

                 Where, Opp = PQ = 6 feet

                                Adj = QR = x

                 Equation (1) becomes,

                      tan 78.96° = [tex]\frac{6}{x}[/tex]

                                     5 = [tex]\frac{6}{x}[/tex]

                                     x = [tex]\frac{6}{5}[/tex] = 1.2

                 Shadow length of Kyle, x = 1.2 feet

Result:

           The shadow length of Kyle is 1.2 feet, if a lighthouse is 150 feet tall and cast a shadow of 30 feet. Kyle is standing next to a lighthouse and is 6 feet tall.

Step-by-step explanation:

Given,

half life of silicon-32 = 710 years

Present silicon-32, N₀ = 90 gm

silicon-32 after 600 years,N = ?

[tex]k = \dfrac{-0.693}{t}[/tex]

[tex]k = \dfrac{-0.693}{710}[/tex]

k = -0.000976

Now,

[tex]N = N_0 e^{kt}[/tex]

[tex]N =90\times e^{-0.000976\times 600}[/tex]

[tex]N = 50.104\ g[/tex]

Hence, the correct answer is option D.

The amount of silicon-32 remaining after 600 years is 50.102 grams

Half life is the time taken for a substance to decay to half of its original amount. It is given by:

[tex]N=N_o(\frac{1}{2} )^\frac{t}{t_\frac{1}{2} } \\\\N\ is\ the\ value\ of\ the\ substance\ after\ t\ year, t_\frac{1}{2} \ is\ the\ half\ life\\and\ N_o\ is\ the \ original\ amount[/tex]

Given that half life = 710 years, original amount is 90 g, t = 600 years, hence:

[tex]N=90(\frac{1}{2} )^\frac{600}{710} \\\\N=50.102\ g[/tex]
