Step-by-step explanation:

The question is incomplete, as the diagram of coordinates of the three triangles are not given.

A general explanation is as follows:

First, record the coordinates of the corresponding points of the three triangles.

For instance; In triangles ABC, DEF and GHI; A, D and G are corresponding points.

Now, assume the coordinates are:

[tex]A = (1,1)[/tex]

[tex]D = (1,5)[/tex]

[tex]G= (-2,1)[/tex]

Point D is 4 points to the right of A;

i.e.

[tex]D =(1,1+4) = (1,5)[/tex]

Hence, ABC will be moved 4 units right to lie on DEF

Similarly, point G is 3 units down of A

i.e.

[tex]G =(1-3,1) = (-2,1)[/tex]

Hence, ABC will be moved 3 units down to lie on GHI.

Answer:

x + y = 60

Step-by-step explanation:

[tex]2x + 2y + 60 = 180 \\ 2x + 2y = 180 - 60 \\ 2x + 2y = 120 \\ \frac{2x + 2y}{2} = \frac{120}{2} \\ x + y = 60 \\ [/tex]

A linear binomial is a factor of a polynomial if the polynomial value is 0 at the zeros of the linear binomial

Assume a polynomial function is

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

And a linear binomial is:

x - 3 = 0

We start by calculating the value of x in x - 3 = 0

x = 3

Next, we substitute x = 3 in P(x) = (x - 3)(x + 1)(x -2)

P(3) = (3 - 3)(3 + 1)(3 -2)

Evaluate

P(3) = 0

Since P(3) = 0, then the linear binomial x - 3 is a factor of P(x) = (x - 3)(x + 1)(x -2)

Answer:

10

Step-by-step explanation:

data=11,7,21,14,9,x

mean=sum of data/no of data

12=11+7+21+14+9+x/6

12*6=62+x

72-62=x

10=x

therefore sixth number is 10.

Step-by-step explanation:

you must have written something wrong.

because given that information OB is not equal to OC.

but for example, OB = BC.

the distance of OB is (5,0) - (0,0) = (5-0,0-0) = (5,0) =

= sqrt(5² + 0²) = sqrt(25) = 5

the distance of OC is (5,5)-(0,0) = (5-0,5-0) = (5,5) =

= sqrt(5² + 5²) = sqrt(50) = 5×sqrt(2)

so, OB is NOT the same as OC.

but BC is (5,5)-(5,0) = (5-5,5-0) = (0,5) = sqrt(0² + 5²) =

= sqrt(25) = 5

Answer:

Lower Bound = 2.996

Upper bound = 3.244

Step-by-step explanation:

40% of 34 000

40/100 * 34 000 = 13 600

subtract : 34000 - 13 600 = 20 400

10% of 20 400

10/100 * 20 400 = 2040

subtract : 20 400 - 2040 = $ 18 360

Answer:

63462 pies

Step-by-step explanation:

De la pregunta anterior, debemos encontrar el área del sector

La fórmula se da como:

θ / 360 × πr²

Dónde:

θ = 45 °

radio = 402 pies

Área del sector =

45/360 × π × 402²

= 63461.742399 pies

Aproximadamente el área de la ocupada por el parque = 63462 pies

Given:

Center of a circle is at point C(-1,2).

AB is the diameter of the circle.

Coordinates of the point A are A(2,6).

To find:

The coordinates of point B.

Solution:

Let the coordinates of point B are (a,b).

If AB is the diameter of the circle, then A and B are end points of diameter of the circle and the center C is the midpoint of AB.

[tex]Midpoint=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)[/tex]

Point C = Midpoint of AB

[tex](-1,2)=\left(\dfrac{2+a}{2},\dfrac{6+b}{2}\right)[/tex]

On comparing both sides, we get

[tex]\dfrac{2+a}{2}=-1[/tex]

[tex]2+a=-1\times 2[/tex]

[tex]a=-2-2[/tex]

[tex]a=-4[/tex]

Similarly,

[tex]\dfrac{6+b}{2}=2[/tex]

[tex]6+b=2\times 2[/tex]

[tex]b=4-6[/tex]

[tex]b=-2[/tex]

Therefore, the coordinates of point B are (-4,-2).

Given:

The function is:

[tex]p(t)=500(0.25)^t[/tex]

Where p(t) represents the number of milligrams of the substance and t represents the time.

To find:

The correct explanation for the number 0.25 and 500 in the given function.

Solution:

The general exponential function is:

[tex]y=ab^x[/tex]           ...(i)

Where, a is the initial value and b is the growth/decay factor. If [tex]0<b<1[/tex], then decay factor and if [tex]b>1[/tex], then growth factor.

We have,

[tex]p(t)=500(0.25)^t[/tex]           ...(ii)

On comparing (i) and (ii), we get

[tex]a=500[/tex], it means initial there are 500 milligrams of the substance.

[tex]b=0.25[/tex], this value is less than 1, it means the substance is decreasing by a factor of 0.25.

Therefore, 0.25 means the substance is decreasing by a factor of 0.25 and 500 means the initial value of substance is 500 milligram.
