Answer:

Step-by-step explanation:

(x-h)^2+(y-h)^2=r^2

radius = 7 = 49

h,k = -2,-3

Answer:

1. (x + 2)^2 + (y + 3)^2 = 49

Step-by-step explanation:

Circle equation: (x-h)^2 + (y-k)^2 = r^2

(h,k) = (-2,-3)

r = 7

(x+2)^2 + (y+3)^2 = 7^2

(x+2)^2 + (y+3)^2 = 49

The first term of a geometric sequence is 32, and the 5th term of the sequence is 818 .

sammy [17]

Answer:

$32,24,18,\frac{27}{2} ,\frac{81}{8}$

Step-by-step explanation:

Let x, y , and z be the numbers.

Then the geometric sequence is $32,x,y,z,\frac{81}{8}$

Recall that term of a geometric sequence are generally in the form:

$a,ar,ar^2,ar^3,ar^4$

This implies that:

a=32 and $ar^4=\frac{81}{8}$

Substitute a=32 and solve for r.

$32r^3=\frac{81}{8}$

$r^4=\frac{81}{256}$

Take the fourth root to get:

$r=\sqrt[4]{\frac{81}{256} }$

$r=\frac{3}{4}$

Therefore $x=32*\frac{3}{4} =24$

$y=24*\frac{3}{4} =18$

$z=18*\frac{3}{4} =\frac{27}{2}$

What is the slope of the line that passes through the points (8,2) and (10,2)? Write your answer in the simplest form.

Oxana [17]

slope of line=(y2-y1)/(x2-x1)

give is

(x1,y1)=(8,2)

(x2,y2)=(10,2)

therefore slope =(2-2)/(10-8)=0/2=0

Hence

answer

Slope of line=0
