Answer:

Equation: 8b=144

Step-by-step explanation:

I am doing the i-ready

the answer is below  

Answer:

Cuando tenemos un binomio como:

(a + b)^2

El desarrollo es:

a^2 + 2*a*b + b^2

Si en cambio, el binomio es de la forma:

(a - b)^2

El desarrollo es:

a^2 - 2*a*b + b^2

Ahora simplemente usemos esas formulas en cada caso:

a) (2 + 5√)^2

(hay una raiz cuadrada ahi que no aplica a nada, asi que supongo que es un error de tipeo)

entonces tenemos que expandir:

(2 + 5)^2 = 2^2 + 2*(2)*(5) + 5^2 = 4 + 20 + 25 = 49

b) (√3 − √5)^2  

= (√3)^2 - 2*(√3)*(√5) + (√5)^2

= 3 - 2*√(3*5) + 5

= 3 - 2*√15 + 5

= 8 - 2*√15

c) (√( + 3) − √( − 3))^2

Acá hago el reemplazo:

√(-3) = i*√3

Recordar que i^2 = -1

Entonces tendremos:

(√( + 3) − √( − 3))^2 =  (√(  3) − i√( 3))^2

= (√3)^2 - 2*i* (√3)(√3) + (i* (√3))^2

=   3 - 2*3*i  + (i^2*3)

= 3 - 6*i - 3

= - 6i

Step-by-step explanation:

1) multiply the two members by 17

x = -68

Answer: Step-by-step explanation:

f(x)=ax^2→g(x)=a(x-h)^2+k

The horizontal shift depends on the value of h. The horizontal shift is described as:  

g(x)=f(x+h) - The graph is shifted to the left h units.

g(x)=f(x−h) - The graph is shifted to the right h units.

Hence, in the question above, Horizontal Shift: Right h Units

The vertical shift depends on the value of k. The vertical shift is described as:

g(x)=f(x)+k - The graph is shifted up k units.

g(x)=f(x)−k - The graph is shifted down k units.

Therefore, in the question above, Vertical Shift: Up k Units

The description of the transformation from the graph with respect to the given graph should be explained below.

Since

[tex]f(x)=ax^2[/tex]

And, [tex]g(x)=a(x-h)^2+k[/tex]

Now here horizontal shift based on the value of h. The horizontal shift should be like

g(x)=f(x+h) - The graph should be shifted to the left h units.

And,

g(x)=f(x−h) - The graph should be shifted to the right h units.

Austen needs to buy a bathroom mirror that is 2 feet wide and 3 feet long. If the mirror sells for $5.00 per square foot, what will the total cost of the mirror be?

Substituting the values given in the 1st formula, We get,

⇒ Area of mirror = ( 3 × 2 ) ft²

⇒ Area of mirror = 6 ft²

Substituting the values calculated above in the 2nd formula, We get

⇒ Total Cost of mirror = $ ( 6 × 5.00 )

⇒ Total Cost of mirror = $30

Answer:

The area of a triangle =55x^3+15x^2-25

1/2×length×width=55x^3+15x^2-25

5x/2×width=55x^3+15x^2-25

width=[55x^3+15x^2-25]×2/5x

width=22x²+6x-10/x is your answer

Answer:

In principle, there is no direct relationship between the area and the perimeter of a rectangle, but both are calculated taking into account the measure of its base and its height.

Thus, the perimeter is equal to the sum of the length of the base and the height of the rectangle, and this result multiplied by 2.

In turn, the area of the rectangle is equal to the multiplication of its base by its height.

So, for example, if the base of the rectangle measured 10 cm and the height measured 5 cm, the perimeter would be equal to 30 cm (10 x 2 + 5 x 2) and the area would be equal to 50 cm2 (10 x 5).

Answer:

[tex]P(Not\ 2019) = \frac{2}{7}[/tex]

Step-by-step explanation:

Given

[tex]n(2019)= 3[/tex]

[tex]n(2001)= 2\\[/tex]

[tex]n(2008)= 2[/tex]

[tex]n = 7[/tex] --- total

Required

[tex]P(Not\ 2019)[/tex]

When two quarters not minted in 2019 are selected, the sample space is:

[tex]S = \{(2001,2001),(2001,2008),(2008,2001),(2008,2008)\}[/tex]

So, the probability is:

[tex]P(Not\ 2019) = P(2001,2001)\ or\ P(2001,2008)\ or\ P(2008,2001)\ or\ P(2008,2008)[/tex]

[tex]P(Not\ 2019) = P(2001,2001) + P(2001,2008) + P(2008,2001) + P(2008,2008)[/tex]

[tex]P(2001,2001) = P(2001) * P(2001)[/tex]

Since it is a selection without replacement, we have:

[tex]P(2001,2001) = \frac{n(2001)}{n} * \frac{n(2001)-1}{n - 1}[/tex]

[tex]P(2001,2001) = \frac{2}{7} * \frac{2-1}{7 - 1}[/tex]

[tex]P(2001,2001) = \frac{2}{7} * \frac{1}{6}[/tex]

[tex]P(2001,2001) = \frac{1}{7} * \frac{1}{3}[/tex]

[tex]P(2001,2001) = \frac{1}{21}[/tex]

[tex]P(2001,2008) = P(2001) * P(2008)[/tex]

Since it is a selection without replacement, we have:

[tex]P(2001,2008) = \frac{n(2001)}{n} * \frac{n(2008)}{n - 1}[/tex]

[tex]P(2001,2008) = \frac{2}{7} * \frac{2}{7 - 1}[/tex]

[tex]P(2001,2008) = \frac{2}{7} * \frac{2}{6}[/tex]

[tex]P(2001,2008) = \frac{2}{7} * \frac{1}{3}[/tex]

[tex]P(2001,2008) = \frac{2}{21}[/tex]

[tex]P(2008,2001) = P(2008) * P(2001)[/tex]

Since it is a selection without replacement, we have:

[tex]P(2008,2001) = \frac{n(2008)}{n} * \frac{n(2001)}{n - 1}[/tex]

[tex]P(2008,2001) = \frac{2}{7} * \frac{2}{7 - 1}[/tex]

[tex]P(2008,2001) = \frac{2}{7} * \frac{2}{6}[/tex]

[tex]P(2008,2001) = \frac{2}{7} * \frac{1}{3}[/tex]

[tex]P(2008,2001) = \frac{2}{21}[/tex]

[tex]P(2008,2008) = P(2008) * P(2008)[/tex]

Since it is a selection without replacement, we have:

[tex]P(2008,2008) = \frac{n(2008)}{n} * \frac{n(2008)-1}{n - 1}[/tex]

[tex]P(2008,2008) = \frac{2}{7} * \frac{2-1}{7 - 1}[/tex]

[tex]P(2008,2008) = \frac{2}{7} * \frac{1}{6}[/tex]

[tex]P(2008,2008) = \frac{1}{7} * \frac{1}{3}[/tex]

[tex]P(2008,2008) = \frac{1}{21}[/tex]

So:

[tex]P(Not\ 2019) = P(2001,2001) + P(2001,2008) + P(2008,2001) + P(2008,2008)[/tex]

[tex]P(Not\ 2019) = \frac{1}{21} + \frac{2}{21} +\frac{2}{21} +\frac{1}{21}[/tex]

Take LCM

[tex]P(Not\ 2019) = \frac{1+2+2+1}{21}[/tex]

[tex]P(Not\ 2019) = \frac{6}{21}[/tex]

Simplify

[tex]P(Not\ 2019) = \frac{2}{7}[/tex]

Given:

The date set is:

0,5,6,7,8,13

To find:

The outliers for the given data set.

Solution:

We have,

0,5,6,7,8,13

Divide the data in two equal parts.

(0,5,6),(7,8,13)

Divide each parenthesis in two equal parts.

(0),5,(6),(7),8,(13)

Here, first quartile is [tex]Q_1=5[/tex] and the third quartile is [tex]Q_3=8[/tex].

The interquartile range (IQR) is:

[tex]IQR=Q_3-Q_1[/tex]

[tex]IQR=8-5[/tex]

[tex]IQR=3[/tex]

The data lie outside the range [tex][Q_1-1.5IQR,Q_3+1.5IQR][/tex] is called outliers.

[tex][Q_1-1.5IQR,Q_3+1.5IQR]=[5-1.5(3),8+1.5(3)][/tex]

[tex][Q_1-1.5IQR,Q_3+1.5IQR]=[5-4.5,8+4.5][/tex]

[tex][Q_1-1.5IQR,Q_3+1.5IQR]=[0.5,12.5][/tex]

The data values 0 and 13 lie outside the range [0.5,12.5].

Therefore, 0 and 13 are outliers of the given data set.

Answer:

  10% loss

Step-by-step explanation:

If Tenzing sold the first watch at 20% profit, his cost c can be found from ...

  1200 = 1.20c

  1000 = c

If Tenzing sold both watches together for 1200 +1350 = 2550, then his total cost can be found from ...

  2550 = 1.02t

  t = 2550/1.02 = 2500

Then his cost for the second watch was ...

  2500 -1000 = 1500

The sale price of 1350 for that watch represents a multiplier m on the watch cost of ...

  1500m = 1350

  m = 1350/1500 = 0.90 = 1 - 0.10

Tenzing lost 10% of its cost on the second watch.

Step-by-step explanation:

The surface area of the given cuboid is 158 cm².

To find the surface area of a cuboid, we need to calculate the areas of its individual faces and then sum them up.

A cuboid has six faces: two identical rectangular faces for the base and top, and four identical rectangular faces for the sides.

Given the dimensions of the cuboid as follows:

Length = 8 cm

Width = 5 cm

Height = 3 cm

The surface area of the cuboid can be calculated as follows:

Area of the base: Length × Width = 8 cm × 5 cm = 40 cm²

Area of the top: Length × Width = 8 cm × 5 cm = 40 cm²

Area of the side face 1: Width × Height = 5 cm × 3 cm = 15 cm²

Area of the side face 2: Width × Height = 5 cm × 3 cm = 15 cm²

Area of the side face 3: Length × Height = 8 cm × 3 cm = 24 cm²

Area of the side face 4: Length × Height = 8 cm × 3 cm = 24 cm²

Now, sum up the areas of all the faces:

40 cm² + 40 cm² + 15 cm² + 15 cm² + 24 cm² + 24 cm² = 158 cm²

Therefore, the surface area of the given cuboid is 158 cm².
