Answer:

5

Step-by-step explanation:

x²-6x+y²+4y+13=0

or, x²-6x+y²+4y+9+4=0

or, x²-6x+9+y²+4y+4=0

or, (x²-2.3.x+3²)+(y²+2.2.y+2²)=0

or, (x-3)²+(y+2)²=0

Square of two positive terms is 0

x-3=0

x=3

and

y+2=0

y=-2

so,

x-y=3+2

=5

Segment CD has point E located on it such that CE:ED = 3:5. If the endpoints are located at C(5, -6) and D(11,18) then what are
wlad13 [49]

Answer:

E(29/4,3)

Step-by-step explanation:

Given that,

Segment CD has point E located on it such that CE:ED = 3:5

The coordinates of C and D are (5, -6) and (11,18) respectively.

We need to find the coordinates of E. Let the coordinates are (x,y). Using section formula to find it as follows :

(x,y)=(\dfrac{m_1x_2+m_2x_1}{m_1+m_2},\dfrac{m_1y_2+m_2y_1}{m_1+m_2})\\\\(x,y)=(\dfrac{3(11)+5(5)}{3+5},\dfrac{3(18)+5(-6)}{3+5})\\\\=\dfrac{29}{4},3

So, the coordinates of E are (29/4,3).

If r = 4 and ^a8 = 100, what is the first term of the geometric<br> sequence?
telo118 [61]

The first term of the geometric  sequence is 0.0061

<u>Step-by-step explanation:</u>

The general form of geometric  sequence is a, ar, ar²,ar³,.......

where,

  • a is the first term of the sequence.
  • r is the common ratio. Here, the common ratio r = 4.
  • The 8th term of the sequence is 100. Hence n = 8.

<u>The formula to find the nth term of the geometric sequence is given by :</u>

⇒ n_{th} term = ar^{n-1}

⇒ 8_{th}term  = a\times4^{8-1}

⇒ 100 = a \times 4^{7}

⇒ 100 = a \times 16384

⇒ a = \frac{100}{16384}

⇒ a = 0.0061

Therefore, the first term of the geometric  sequence is 0.0061
