Answer:

what langue is that

Step-by-step explanation:

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

Answer:

c

Step-by-step explanation:c

2xy^2+xy^2+xy-2x

2x(y^2-1)+xy(y+1)

2x(y-1)(y+1)+xy(y+1)

(y+1)(2xy-2x+xy)

(y+1)(3xy-2x)

3xy² + xy - 2x

= x (3y² + y - 2)

= x (3y² + 3y - 2y - 2)

= x {3y (y + 1) - 2 (y + 1)}

= x (y + 1) (3y - 2)

Answer:

[tex]x (y + 1) (3y - 2)[/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:

A cada miembro de la familia le correspondieron $1.540.

Step-by-step explanation:

Dado que José ahorró $800 por mes durante 11 meses, y se dejó la octava parte de lo que ahorró, y el resto lo repartió en partes iguales entre su esposa y sus 4 hijos, para determinar cuánto le corresponde a cada miembro de la familia se debe realizar el siguiente cálculo:

((800 x 11) x 7/8) / (4 + 1) = X

(8800 x 0.875) / 5 = X

7700 / 5 = X

1540 = X

Por lo tanto, a cada miembro de la familia le correspondieron $1.540.

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.

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:

Your answer would be √10, or square root of 10.

Answer:

Step-by-step explanation:

A = 40* (365/5)= 29.2%

B = 50*(365/12) = 15.2%

C= 80*(365/15)=19.46%

D = 100*(365/20)=18.25%

so best is B,  then D , then C then A .  

B,D,C,A   in lowest to highest APR

As per the given data, with a base of $400 for loan amount, the ranking of all the given companies from the lowest to highest annual percentage rate is B,D,C, and A.

Annual borrowing costs, including fees, are stated as a percentage and are known as the annual percentage rate, or APR. The APR is a more comprehensive indicator of how much borrowing money will cost because it includes both interest rates and application fees.

Instead of just a monthly fee or rate, the term annual percentage rate of charge refers to the interest rate for the entire year as applied to a loan, home loan, credit card, and many more. It can also be referred to as a nominal APR or an effective APR. It is a financial fee that is calculated at an annual rate.

Required calculations are as follow:

A = 40 × (365/5)= 29.2%

B = 50 × (365/12) = 15.2%

C= 80 × (365/15)=19.46%

D = 100 × (365/20)=18.25%

Therefore, the ranking of all the companies  with the lowest to highest annual percentage rate are B,D,C, and A.

Given

Let:

[tex]S \to[/tex] Strawberry

[tex]G \to[/tex] Grape

The given parameter can be represented as:

[tex]S : G = 2 : 5[/tex]

Required

The question is incomplete as what is required is not stated.

Possible questions could be to determine the number of strawberries given a certain number of grapes, and vice versa

Take for instance

Calculate the number of grapes when there are 20 strawberries

We have:

[tex]S : G = 2 : 5[/tex]

This becomes

[tex]20 : G = 2 : 5[/tex]

Express as fraction

[tex]\frac{20}{ G} = \frac{2 }{5}[/tex]

Make G the subject

[tex]G = 20 * \frac{5}{2}[/tex]

[tex]G = 10 * 5[/tex]

[tex]G = 50[/tex]

Answer:

p=28.2

Step-by-step explanation:

l=9.8

w=4.3

it was close tho

Answer :    28.4 cm

                                                   Lower     Upper

Length is given as 9.8    -->         9.75 ≤ L < 9.85

width is given as 4.3      -->           4.25 ≤ w < 4.35

Perimeter = 2L + 2w     (Upper bound)

               = 2(9.85) + 2(4.35)

               =   19.7      +   8.7

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.

Answer:

a. π(92)(9) − 1 over 3π(92)(9)

Step-by-step explanation:

Solution given: For A

height =9units

breadth =9units

for both cylinder and cone

Volume of container A=volume of cylinder -volume of cone

=πr²h-1/3×πr²h=π(9²)9-1/3×(9²)9

so your final answer is A

a. π(92)(9) − 1 over 3π(92)(9)

The volume of the container A and container B will be π(9²)9 – (1/3)π (9²)h. Then the correct option is A.

It deals with the size of geometry, region, and density of the different forms both 2D and 3D.

Container A is a cylinder with a radius of 9 units and a height of 9 units. A right cone has been carved from its base and has a height of 9 units.

Then the volume of the container A will be given as

Volume of A = Volume of cylinder – volume of cone

Volume of A = πr²h – (1/3)πr²h

Volume of A = π(9²)9 – (1/3)π (9²)h

Volume of A = (2/3) π(9)³

Container B has the same radius as container A.

Volume of B = (4/6) πr³

Volume of B = (2/3) π(9)³

Then the correct option is A.
