If (x+2)^2+(y-5)^2=25 is the equation of a circle, which statement describes the circle's graph?
Aleonysh [2.5K]

Answer:

B

Step-by-step explanation:

The standard form of a circle is

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

where h and k are the coordinates of the center of the circle and the radius is squared.  The radius is easy...take the square root of 25 to get that the radius is 5.  Since the pattern for the standard form is "x-" and "y-", if (x+2)^2 is the horizontal placement of the center, it actually was originally written as (x-(-2))^2, so the h coordinate is -2.  Same goes for the vertical movement of the center.  (y-(5))^2 means that the k coordinate is a positive 5.

Solve (x+1&lt;4)∩(x-8&gt;-7)
tino4ka555 [31]

We can rewrite the two sets as

x+11

So, the first set is composed by all numbers smaller then 3, and the second is composed by all numbers greater than 1.

The intersection of two sets is composed by all the elements appearing in both sets, so

\{x1\}

Is the set composed by all number that are less than 3 and more than 1, at the same time.

In other words, you're simply asking

\{1

Ok here is a better pic I need help with it​
BartSMP [9]

Answer:

Step-by-step explanation:

First,You have to realize that if you multiply the amount of food by something, you multiply the amount of calories.  if some piece of food is 100 calories what happens if you eat 2?  you get 2 times that number of calories.  Same fi you eat half of one of that kind of food.  You get half the amount of calories.

Here he makes 1 1/2 (one and a half) times the amount.  Now, if this is confusing  you just need to realize that  multiplying by this is the same as multiplying by 1+1/2.  Say, again, a piece of food is 100 calories.  Multiplying it by this would look like the following.

100(1+1/2)

100*1 + 100*1/2

100+50

150

So if you ever have a mixed number like this  you could split it up into an addition problem and then distribute hat you're multiplying.  Another solution is to multiply by the improper fraction, which here is 3/2, so 100*3/2=150 as well.  Let me know if you don't get how to get the improper fraction or how to multiply fractions.

Now, super simple, just multiply the calories by that number.

310(1+1/2) = 310(3/2)

310 + 155 = 930/2

465 = 465

Kinda showed how to multiply by fractions, still if you don't get it let me know.
