Answer:

(a) center: (0, 0); radius: 4

(b) center: (8, -3); radius: 10

(c) center: (-2, -7); radius: 7

(d) center: (6, 0); radius: 1

(e) center: (0, 0); radius: 5

(f) center: (3, 8); radius: 8

Step-by-step explanation:

In the figure attached, the complete question is shown.

Equation of a circle with center (h, k) and radius r:

(x - h)² + (y - k)² = r²

Complete the statements about the series
AleksAgata [21]

Answer:

Ok, first in our series we can see two numbers in the Sigma, one bellow 0, and other above, 4.

This means that the value of k will go from 0 to 4, then all the numbers in the sum are:

(-1/2)^0 + (-1/2)^1 + (-1/2)^2 + (-1/2)^3 + (-1/2)^4

So we have 5 terms in our series.

b) to see the sign in each term, we must solve the powers, remember that:

(-1)^n is -1 if n is odd, and is equal to 1 if n is even, so we have:

(-1/2)^0 + (-1/2)^1 + (-1/2)^2 + (-1/2)^3 + (-1/2)^4

= 1 -1/2 + 1/4 - 1/8 + 1/16.

So the sign in each term of the series alternates.

A music store sells used cds for $5 each and buys used CDs for$1.50 each. you go to the store with $20 and some CDs to sell. you
olya-2409 [2.1K]
Let x be the number of CDs we buy and y the number of CDs we sell. 
Each CD sell for $1.5, then the total of money we earn is $1.5y.
Each CD bought for $5, then the total money spent is $-5x
Add the above values like this:
1.5y-5x
We have $20, add them like this:
1.5y-5x+20
Since we want to have<span> at least $10 left when you leave the store, then 
we deduce the equation:
</span>1.5y-5x+20\leq 10

You flip three coins. What is the probability that you get three tails, given that you get at least two tails?
rjkz [21]
It’s still 50/50. Flipping coins is purely chance. There isn’t an actual pattern, our brain just create one to make sense of things!
