If the equation of a circle is (x+5)2+(x-7)2=<br> 36, its radius is
Arturiano [62]

Answer:

6

Step-by-step explanation:

The equation for a circle is (x-h)^2 +(y-k)^2 = r^2

where (h,k) is the center of the circle and r is the radius

(x+5)^2+(y-7)^2= 36

Rewriting

(x+5)^2+(y-7)^2=6^2

The center is at (-5,7) and the radius is 6

Determine whether each of these sets is countable oruncountable. For those that are countably infinite, exhibit
mezya [45]

Answer:

Answers are given below.

Step-by-step explanation:

a) one-to-one correspondence between the set of positiveintegers and that set.

Whenever we have one to one correspondence with positive integers, the set is countable and here infinite.

b) integers divisible by 5 and not 7 ..This set is all integers divisible by 5 but not by 7.  This is a discrete set and hence countable and infinite.

c) the real numbers with decimal representationsconsisting of all 1’s

-- This cannot be counted and hence uncountable but infinite.

d) the real numbers with decimal representationsconsisting of all 1’s or 9’s

-- This is also uncountable but infinite.
