Answers

Answer 1

Answer:

-2.

Step-by-step explanation:

4x + 5y = -12

-23.4x + 3y = -16

23.4[4x + 5y = -12]

4[-23.4x + 3y = -16]

93.6x + 117y = -280.8

-93.6x + 12y = -64

129y = -344.8

y = -2.672868217

That is about -2.

To work out the area in m² of material required for a pair of curtains, a seamstress squares the height of the window in m and adds 0.5.

a) What area of material is required for a window of height 1.2meters?

b) What area of material is required for a window of height p meters?

c) if the area of material required is 2.75m²,what is the height of the window?​

Answers

Answer:

a. Area = 1.94m²

b. Area = (p² + 0.5)m²

c. Height = 1.5m

Step-by-step explanation:

Given

Let H represents Height and A represents Area

From the first and second statements, we have that:

[tex]A = H^2 + 0.5[/tex]

a. Calculating Area When Height = 1.2

[tex]A = H^2 + 0.5[/tex]

Substitute 1.2 for H

[tex]A = 1.2^2 + 0.5[/tex]

[tex]A = 1.44 + 0.5[/tex]

[tex]A = 1.94[/tex]

Hence, the area is 1.94m²

b. Calculating Area When Height = p

[tex]A = H^2 + 0.5[/tex]

Substitute p for H

[tex]A = p^2 + 0.5[/tex]

Hence, the area is (p² + 0.5)m²

c. Calculating Height When Area = 2.75m²

[tex]A = H^2 + 0.5[/tex]

Substitute 2.75 for A

[tex]2.75 = H^2 + 0.5[/tex]

Subtract 0.5 from both sides

[tex]2.75 - 0.5 = H^2 + 0.5 - 0.5[/tex]

[tex]2.75 - 0.5 = H^2[/tex]

[tex]2.25 = H^2[/tex]

Take Square Root of both sides

[tex]\sqrt{2.25} = \sqrt{H^2}[/tex]

[tex]\sqrt{2.25} = H[/tex]

[tex]1.5 = H[/tex]

[tex]H = 1.5[/tex]

Hence, the height is 1.5m

A spherical mirror gives an image magnified 5 times at a distance 5 m. determine whether the mirror is convex or concave? How much will be the focal length of the mirror?

Answers

Answer:

a) The mirror is concave

b) The focal length of the mirror = -1.25m or -5/4 m

Step-by-step explanation:

a) Determine whether the mirror is convex or concave?

A concave mirror is a spherical mirror that it's magnification is equal to, less than or more than 1 while a convex mirror is a mirror whereby it magnification is always less than one.

From the above question we are told that the spherical mirror is magnified 5 times.

Hence, because the spherical mirror is magnified 5, it is a concave mirror.

b) Magnification = - image distance/ object distance

Magnification = 5

Image distance = 5m

Object distance = ???

5 = -5/Object distance

Object distance = -5/5

= -1m

Formula for focal length =

1/f = 1/v + 1/u

v = image distance = 5

u = object distance = -1

1/f = 1/5 +1/-1

1/f = 1/5 - 1

1/f = -4/5

f = -5/4

f = -1.25m

The focal length of the mirror = -1.25m

Music CD's cost $9 each, and movies cost $10 each. If you
spend $78 and buy 8 items, how many of each did you buy?

Answers

Answer:

2 CDs and 6 movies

Step-by-step explanation:

Let the number of CD you bought be x, and the number of movies you bought be y.

Since you bought 8 items in total,

x + y = 8 ______(1)

The sum of money spent is 78, so

9x + 10y = 78 ________(2)

From equation (1),

x = 8 - y ________(3)

Substitute (3) into (2),

9 (8-y) + 10y = 78

72 - 9y + 10y = 78

- 9y + 10y = 78-72

y = 6

Now substitute y=6 into (3).

x = 8 - y

x = 8-6

x = 2

Therefore, you bought 2 CDs and 6 movies.

Suppose that a bacterial culture was known to double every 2 days. After 46 days, it covered the entire surface area in the petri dish. When did it cover half the area? Explain.

Answers

Answer:

in day 44 it covered half the area.

Step-by-step explanation:

A bacterial culture doubles every two days, so if today it covers [tex]3 cm^2[/tex], in two days it will cover [tex]6cm^2[/tex]. In other words, if today it covered x space, two days ago it covered half the space [tex](\frac{x}{2})[/tex].

Now, following that reasoning, we have that after 46 days the bacterial culture covered the entire surface area in the Petri dish, therefore, two days ago it covered half the area and we can conclude that in day 44 it covered half the area.

What is the solution to this equation?
X +8=-3
A. x=-11
B. x= 11
c. x= -5
D. x = 5

Answers

Answer:

Option A

Step-by-step explanation:

x + 8 = -3

x + 8 - 8 = -3 - 8

x = - 11

Answer:

A. x= -11

Step-by-step explanation:

We want to solve for x. Therefore, we must get x by itself on one side of the equation.

x+8= -3

8 is being added to x. The inverse of addition is subtraction. So, subtract 8 from both sides of the equation.

x+8-8=-3-8

x= -3-8

x= -11

Now let’s check our solution. Plug -11 in for x in the original equation.

x+8=-3

-11+8=-3

-3=-3

This checks out, so we know our solution is correct and A. x= -11 is the correct choice.

Find the probability of selecting none of the correct six integers in a lottery, where the order in which these integers are selected does not matter, from the positive integers not exceeding the given integers. (Enter the value of probability in decimals. Round the answer to two decimal places.) 40

Answers

Answer:

Probability of selecting none of the correct six integers:

a) 0.350

b) 0.427

c) 0.489

d) 0.540

Step-by-step explanation:

a) 40

Given:

Number of integers in a lottery  6

Order in which these integers are selected does not matter

To find:

Probability of selecting none of the correct six integers

Solution:

When the order of selection does not matter then we use Combinations.

Given integers = 40

Number of ways to choose 6 from 40.

Let A be the sample space of choosing digits 6 from 40.

Then using Combinations:

(n,k) = n! / r! (n-r)!

n = 40

r = 6

40C6

=(40,6) = 40! / 6! ( 40 - 6)!

           = 40! / 6!34!

           = 40*39*38*37*36*35*34! / 6!34!

           = 2763633600 / 720

          = 3838380

Let E be the event of selecting none of the correct six integers.

So using combinations we can find the total number of ways of selecting none of 6 integers from 40

n = 40 - 6 = 34

r = 6

34C6

=(34,6) = 34! / 6! ( 34 - 6)!

           = 34! / 6! 28!

           = 34 * 33 * 32 * 31 * 30 * 29 * 28! / 6! 28!

           =968330880 / 720

           = 1344904

Probability of selecting none of the correct six integers:

P(E) = E / A

       = 1344904 / 3838380

        = 0.350

Probability of selecting none of the correct six integers is 0.350

b) 48

Following the method used in part a)

(n,k) = n! / r! (n-r)!

n = 48

r = 6

48C6

=(48,6) = 48! / 6! ( 48 - 6)!

            = 48! / 6! ( 42 )!

            = 48*47*46*45*44*43*42! / 6!42!

            = 8835488640 / 720

            = 12271512

Let E be the event of selecting none of the correct six integers.

So using combinations we can find the total number of ways of selecting none of 6 integers from 48

n = 48 - 6 = 42

r = 6

42C6

= (42,6) = 42! / 6! ( 42 - 6)!

              = 42! / 6! 36!

              = 3776965920

              = 5245786

P(E) = E / A

       = 5245786/12271512

       = 0.427

c) 56

(n,k) = n! / r! (n-r)!

n = 56

r = 6

56C6

=(56,6) = 56! / 6! ( 56- 6)!

            = 56! / 6! ( 50 )!

            = 56*55*54*53*52*51*50! / 6! 50!

            = 23377273920/6

            = 32468436

Let E be the event of selecting none of the correct six integers.

So using combinations we can find the total number of ways of selecting none of 6 integers from 56

n = 56 - 6 = 50

(50,6) = 50! / 6! ( 50- 6)!

           = 50*49*48*47*46*45*44! / 44! 6!

           = 11441304000 / 6

           = 15890700

P(E) = E / A

       = 15890700 / 32468436

      = 0.489

d) 64

(n,k) = n! / r! (n-r)!

n = 64

r = 6

64C6

=(64,6) = 64! / 6! ( 64 - 6)!

            = 64! / 6! ( 58 )!

            = 64*63*62*61*60*59*58! / 6! 58!

            = 53981544960 / 720

            = 74974368

Let E be the event of selecting none of the correct six integers.

So using combinations we can find the total number of ways of selecting none of 6 integers from 64

n = 64 - 6 = 58

(58,6) = 58! / 6! ( 58- 6)!

           = 58*57*56*55*54*53*52! / 52! 6!

           = 29142257760/ 6

           = 40475358

P(E) = E / A

       = 40475358/ 74974368

      = 0.540

The probability of selecting none of the correct six integers in a lottery is, 0.350.

Number of integers given = 40

So, Total outcomes for choosing 6 from 40 integers.

         Number of arrangements [tex]=_{6}^{40}\textrm{C}[/tex]

                                                    [tex]=\frac{40!}{6!*34!} =3838380[/tex]

Since, we have to find probability of selecting none of the correct six integers in a lottery.

Remaining integer = 40 - 6 =34

Let favourable outcomes is selecting none of the correct six integers.

So, number of arrangements, = [tex]=_{6}^{34}\textrm{C}[/tex]

                                                 = [tex]\frac{34!}{6!*28!}=1344904[/tex]

Probability is defined as, divide favourable outcomes by total outcomes.

So, The probability of selecting none of the correct six integers in a lottery,

                            [tex]P=\frac{1344904}{3838380}=0.35[/tex]

2. Susan wants to use blue, yellow, green, and pink paint to decorate her house. She needs 3 times as much blue paint as yellow paint and ½ much yellow paint as green paint. She needs 3 ¼ gallons of pink paint, which is ¾ of a gallon more than the green paint she needs. How much paint does Susan need in all?

Answers

Answer:

B = Blue

Y = Yellow

G = Green

P = Pink

The info that we have is:

3*B = Y

(1/2)Y = G

P = (3 + 1/4) gal

P = G + 3/4 gal.

So we have 4 equations. The first step is replacing the third equation into the fourth equation, and get:

G + 3/4 gal = (3 + 1/4) gal

G = (3 + 1/4) gal - 3/4 gal = (2 + 2/4) gal

Now we can replace this into the second equation ((1/2)*Y = G) to find the value of Y.

(1/2)Y = (2 + 2/4) gal

Y = 2*(2 + 2/4) gal = (4 + 1)gal = 5 gal.

Now we can replace this into the first equation and get:

3*B = 5gal

B = 5/3 gal = (1 + 2/3)gal

So the total amount of paint used is:

T = P + G + Y + B = (3 + 1/4) gal +  (2 + 2/4) gal + 5gal + (1 + 2/3)gal

T = (11 + 3/4 + 2/3)gal

T = (11 + 9/12 + 8/12)gal = (11 + 17/12)gal = (11 + 1 + 5/12)gal = (12 + 5/12) gal.

Answers

Answer: 90 degrees clockwise rotation

Step-by-step explanation:

Common rotations about Origin :

90° clockwise    (x,y)→(y,-x)

90° counterclockwise    (x,y)→(-y,x)

180°       (x,y)→ (-x,-y)

270°  clockwise     (x,y)→(-y,x)

Given:  Julio’s rotation maps point K(–6, 9) to K’(9, 6).

Rotation corresponding to this is (x,y) → (y,-x) since K(–6, 9) → K’(9, -(-6)) = K(9,6).

Therefore, Julio’s rotates 90° clockwise to map point K(–6, 9) to K’(9, 6).

Waves with an amplitude of 2 feet pass a dock every 30 seconds. Write an equation for a cosine function to model the height of a water particle above and below the mean water line. Explain your steps.

Answers

Answer:

The cosine function to model the height of a water particle above and below the mean water line is h = 2·cos((π/30)·t)

Step-by-step explanation:

The cosine function equation is given as follows h = d + a·cos(b(x - c))

Where:

[tex]\left | a \right |[/tex] = Amplitude

2·π/b = The period

c = The phase shift

d = The vertical shift

h = Height of the function

x = The time duration of motion of the wave, t

The given data are;

The amplitude [tex]\left | a \right |[/tex] = 2 feet

Time for the wave to pass the dock

The number of times the wave passes a point in each cycle = 2 times

Therefore;

The time for each complete cycle = 2 × 30 seconds  = 60 seconds

The time for each complete cycle = Period = 2·π/b = 60

b = π/30 =

Taking the phase shift as zero, (moving wave) and the vertical shift as zero (movement about the mean water line), we have

h = 0 + 2·cos(π/30(t - 0)) = 2·cos((π/30)·t)

The cosine function is h = 2·cos((π/30)·t).

Answers

Answer:

Step-by-step explanation:

Hello!

a)

You have three triangles and you have to find the ratio of the adjacent sides to the angle 23.1º

Remember, considering a specific angle ∠, "the adjacent sides" are those that make contact with the angle and the "opponent side" is the one that is in the opposite side of the angle and the hypotenuse is the longest side of the right triangle, always opposed to the right angle.

First triangle, the adjacent sides, are

JL= 20.17m (hypotenuse)

JK= 18.55m

Ratio: [tex]\frac{JK}{JL}= \frac{18.55}{20.17}= 0.9196= 0.92[/tex]

Second triangle, adjacent sides:

PR= 141.19m (hypotenuse)

PQ= 129.85m

Ratio: [tex]\frac{PQ}{PR} = \frac{129.85}{141.19}= 0.9196= 0.92[/tex]

Third triangle, adjacent sides:

XZ= 181.53m (hypotenuse)

XY= 166.95m

Ratio: [tex]\frac{XY}{XZ} = \frac{166.95}{181.53} = 0.9196= 0.92[/tex]

b)

Using the calculator you have to calculate the trigonometric ratios of 23.1º:

sin(23.1º)= 0.392= 0.39

cos(23.1º)= 0.9198= 0.92

tan(23.1º)= 0.426= 0.43

c)

To calculate the trigonometrical ratios manually you have to do as follows:

Consider the angle A

[tex]sinA= \frac{opposite}{hypotenuse}[/tex]

[tex]cosA= \frac{adjacent}{hypotenuse}[/tex]

[tex]tanA= \frac{opposite}{adjacent}[/tex]

In item a) you calculated the ratios of the adjacent sides of the angle by the hypotenuse, this is equal to the cosine of the given angle.

I hope this helps!

Stratified sampling: Here, the total population are divided into subcategories (strata) before sampling is done. The strata are formed based on some common characteristics. In our example, the times of the day (morning, afternoon and evening) has widely varying atmospheric conditions which will add biases to the measurement of air quality. For example, the air in the morning if compared to the afternoon in an industrial area may be purer because of minimal industrial activity, hence effective comparison will be made by stratification.

Answer:

[tex]\frac{9}{a - b}[/tex].

Step-by-step explanation:

a^2 - b^2 = 9

(a + b)(a - b) = 9

a + b = [tex]\frac{9}{a - b}[/tex].

ab = 3

a = 3/b

3/b + b = [tex]\frac{9}{\frac{3}{b} -b}[/tex]

3 + b^2 = [tex]\frac{9b}{\frac{3}{b}-\frac{b^2}{b} }[/tex]

3 + b^2 = [tex]\frac{9b}{\frac{3-b^2}{b} }[/tex]

3 + b^2 = [tex]9b * \frac{b}{-b^2 + 3}[/tex]

3 + b^2 = [tex]\frac{9b^2}{-b^2 + 3}[/tex]

(b^2 + 3)(-b^2 + 3) = 9b^2

-b^4 + 9 = 9b^2

b^4 + 9b^2 - 9 = 0

Let's say that b^2 = x

x^2 + 9x - 9 = 0

Hope this [somewhat] helps!

Answer:

Step-by-step explanation:

a²-b²=9

ab=3 then a=3/b

a²-b²=9

(a+b)(a-b)=9 ( the values has to b (3*3) or (9*1)

but since ab=3. so the value has to be (3*3)

(a+b)(a-b)=9

3*3=9

a+b=3

ab=3

Write these series with summation notation. 1,4,9,16...

Answer:  [tex]\sum\limits_{i=1}^{n} n^2[/tex] , where n is a natural number.

Step-by-step explanation:

A series can be represented in a summation or sigma notation.

Greek capital letter, ∑ (sigma), is used to represent the sum.

For example: [tex]\sum\limits_{n=1}^{\infty} n=1+2+3+4+5+...[/tex], where n is a natural number.

The given series : 1,4,9,16 which can be written as [tex]1^2, 2^2, 3^2,...[/tex] .

So , we can write it as

[tex]\sum\limits_{n=1}^{\infty} n^2[/tex] , where n is a natural number.

What is the explicit formula for this sequence?

Answers

Greetings from Brasil...

With the recursive formula, lets build the sequence:

A1 = 4

A2 = A1 - 7

A3 = A2 - 7

A4 = A3 - 7

A5 = A4 - 7

(...)

But pay attention to A3....

A3 = A2 - 7   but  A2 = A1 - 7 , so rewriting A3

A3 = (A1 - 7) - 7 ⇒ A3 = A1 + 2.(- 7)

A4 = A3 - 7 ⇒ A4 = [(A1 - 7) - 7] - 7 = A1 + 3.(- 7)

A5 =  {[(A1 - 7) - 7] - 7} - 7 = A5 + 4.(- 7)  

so

An = A1 + (n - 1).(- 7)

The following box plot shows the number of years during which 40 schools have participated in an interschool swimming meet: A box and whisker plot is drawn using a number line from 0 to 10 with primary markings and labels at 0, 5, 10. In between two primary markings are 4 secondary markings. The box extends from 1 to 6 on the number line. There is a vertical line at 3.5. The whiskers end at 0 and 8. Above the plot is written Duration of Participation. Below the plot is written Years. At least how many schools have participated for more than 1 year and less than 6 years?

Answers

Answer:

Step-by-step explanation:

The box encloses data between the two quartiles, namely at least half of the data.  If there are 40 schools, then half of them would be in the box, between 1 and 6.

see attached plot.

Answer:

really hard to tell what the box plot is like without an attachment so im gonna help u find it out anyway

Step-by-step explanation:

basically when u look at a  box plot and the range the line in the middle is the median  and then the max the lowest range the lower quartile and then the higher quartile you can find ur anser, simply find the median first, find where the lower quartile is and then the lowest number in the group thats in betweeen 1 and 6
