Step-by-step explanation:

The sine of the coordinate point is the y value.

Answer:

-2

Step-by-step explanation:

First you want to seperate the c. To do that you divide by both sides so -12/c divide -12 cancels out to be just 1/C. 6 divide -12 is -0.5. Know we have 1/c = -0.5 and that is -2. -2 is your answer :)

Answer:

Step-by-step explanation:

2.1     Factoring  9y2+30y-14

The first term is,  9y2  its coefficient is  9 .

The middle term is,  +30y  its coefficient is  30 .

The last term, "the constant", is  -14

Step-1 : Multiply the coefficient of the first term by the constant   9 • -14 = -126

Step-2 : Find two factors of  -126  whose sum equals the coefficient of the middle term, which is   30 .

     -126    +    1    =    -125

     -63    +    2    =    -61

     -42    +    3    =    -39

     -21    +    6    =    -15

     -18    +    7    =    -11

     -14    +    9    =    -5

     -9    +    14    =    5

     -7    +    18    =    11

     -6    +    21    =    15

     -3    +    42    =    39

     -2    +    63    =    61

     -1    +    126    =    125

Answer:

9372000

Step-by-step explanation:

9372282 rounds to 9372000

Since we're rounding to the thousand, we need to look at the number in the hundreds place, in this case it's 2 (9372282). 2 is lower than 5, so we round down. If it was 5 or higher, we'd round up. Rounding down means, we just keep the other 2 as a 2 (9372282), and change the numbers after to 0s (9372000)  

Answer:

C. -2

Step-by-step explanation:

A (x,y)   B(x',y')      slope of AB = (y'-y)/(x'-x) = -2

After dilation with factor of 2:

A' (2x,2y)     B' (2x',2y')   slope of A'B' = (2y'-2y)/(2x'-2x) = (y'-y)/(x'-x) = -2

The slope of A' B' is the same as the slope of AB, which is -2.

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

The slope of line AB is -2, and the slope of A' B' can be found by applying the transformation to the slope of AB.

Since the dilation is centered at the origin and has a scale factor of 2, the slope of line A' B' is also -2.

This is because the transformation multiplies the distances between points by 2 in every direction, but it does not change the angle between the lines.

Therefore, the slope of A' B' is the same as the slope of AB, which is -2.

Answer:

I got -6 + 2i

Step-by-step explanation:

(3-5i)(-2+4i)

So we would multiply the following:

3*-2 = -6

3*4i =12i

-5i*-2 = 10i

-5i * 4i = -20i

Therefore the expression would be

- 6 + 12i + 10i - 20i

we then would add and subtract the variables, which would be

-6 + 2i

Just put that in the calculator tbh

Step-by-step explanation:

Given equation ,

=> x = 10 - y

When x = 0

=> y = 10 - x

=> y = 10 -0 = 10

===========================================

When x = 1

=> y = 10 -1 = 9

===========================================

When x = 2

=> y = 10-2 = 8

Answer:

(0, 10), (1,9), (2,8)

Step-by-step explanation:

Substitute your x values and solve for y.

0=10-y (Subtract 10)

-10=-y (Divide by -1)

10=y

1=10-y (Subtract 10)

-9=y (Divide by -1)

9=y

2=10-y (Subtract 10)

-8=y (Divide by -1)

8=y

Queremos resolver distintas cosas en relación a las dimensiones de un rectangulo, las respuestas son:

a) 80m = 2*(x + y)

b) A = (40m - y)*y = 40m*y - y^2

c) El grafico se puede ver al final de la respuesta.

d) Tanto el largo como el ancho deben ser iguales a 20m

Luis quiere colocar un cerco rectangular, definamos, x como el largo e y como el ancho de este rectangulo.

Recordar que el area está dada por:

A = x*y

y el perimetro está dado por:

P = 2*(x + y)

Ahora sabemos que el desea utilizar una malla de 80 metros de longitud, es decir, el perimetro debe ser:

P = 80m = 2*(x + y)

Ahora tenemos una ecuación que relaciona las dimensions del terreno.

a) 80m = 2*(x + y)

b) La ecuación del area es:

A = x*y

Usando la ecuación del inciso (a) podemos escribir:

80m = 2*(x + y)

40m = x + y

x = 40m - y

Ahora podemos reemplazar esto en la ecuación del area:

A = (40m - y)*y = 40m*y - y^2

c) El grafico se puede ver al final de la respuesta.

d) Queremos maximizar el area.

Notar que la ecuación del area es cuadratica, es decir, el máximo esta en el vertice, y el vertice está dado por:

y = -40m/(2*-1) = 20m

Usando la ecuación x = 40m - y podemos encontrar el valor de x:

x = 40m - y = 40m - 20m = 20m

Es decir, el largo y el ancho deben ser iguales a 20 metros.

b) There is a 0.3261 = 32.61% probability that a male interviewee chooses ’Shopping Tour’.

c) The proportion of females is of 0.7059 = 70.59%.

d) There is a 0.6061 = 60.61% probability that this person is a female.

e) There is a 0.3953 = 39.53% probability that she chooses “River Cruise”.

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

Item a:

Hence:

[tex]p = \frac{15}{101} = 0.1485[/tex]

0.1485 = 14.85% probability that an interviewee chooses ‘Eco Trip’.

Item b:

20 + 15 + 11 = 46 male interviewees, 15 choose Shopping Tour, hence:

[tex]p = \frac{15}{46} = 0.3261[/tex]

0.3261 = 32.61% probability that a male interviewee chooses ’Shopping Tour’.

Item c:

15 + 36 = 51 interviewees choose Shopping Tour, 36 are female, hence:

[tex]p = \frac{36}{51} = 0.7059[/tex]

The proportion of females is of 0.7059 = 70.59%.

Item d:

15 + 36 + 11 + 4 = 66 interviewees do not choose River Cruise, 36 + 4 = 40 are female, hence:

[tex]p = \frac{40}{66} = 0.6061[/tex]

0.6061 = 60.61% probability that this person is a female.

Item e:

101 - 15 = 86 people do not choose Eco Trip, of those, 34 choose River Cruise, hence:

[tex]p = \frac{34}{86} = 0.3953[/tex]

0.3953 = 39.53% probability that she chooses “River Cruise”.
