Answer:

(h,k)=(-1,-3)

radius =10/2=5 unit

equation of the circle

(x-h)² +(y-k)²=r²

(x+1)²+(y+3)²=25 is a required equation..

The first term of a geometric sequence is -2 and the common ratio is -1/4. what are the next three terms of the sequence?

MA_775_DIABLO [31]

Answer:

$\frac{1}{2},-\frac{1}{8}, \frac{1}{32}$

Step-by-step explanation:

From the question;

The first term of a geometric sequence, a₁ is -2
The common ratio, r is -1/4

We are required to determine the next three terms of the sequence;

We need to know that;

nth term is a geometric sequence is given by;

$T_n=a_1r^n^-^1$

Therefore;

Second term will be given by;

$T_2=-2(-\frac{1}{4})^2^-^1$

$T_2=-2(-\frac{1}{4})^1$

$T_2=\frac{1}{2}$

Third term will be given by;

$T_3=-2(-\frac{1}{4})^3^-^1$

$T_3=-2(-\frac{1}{4})^2$

$T_3=-2(\frac{1}{16})$

$T_3=1\frac{1}{8}$

Fourth term will be given by;

$T_4=-2(-\frac{1}{4})^4^-^1$

$T_4=-2(-\frac{1}{4})^3$

$T_4=-2(-\frac{1}{64})\\T_4=\frac{1}{32}$

Thus, the next three terms are; $\frac{1}{2},-\frac{1}{8}, \frac{1}{32}$

Wayne is solving a system of linear equations.

Ulleksa [173]

Answer:

(-2, 6.5)

Step-by-step explanation:

Wayne can follow the line from (-2, 0) up to where it crosses the graphed line. The crossing point is approximately halfway between 6 and 7 on the graph, so can be considered to be 6.5.

If we put x=-2 into the equation and evaluate, we get ...

... y = (-3/4)(-2) +5 = 6/4 +5 = (1 1/2) +5 = 6 1/2

Thus the solution is (-2, 6 1/2).
