What is the general form of the equation of a circle at (-2,1) and passing through (-4,1)?

The general form of the equation of a circle with radius ' r '
and centered at  (a, b)  is

                              (x - a)² + (y - b)²  =  r²

I'm pretty sure that your circle is not "at (-2,1)".
I'm going to approach your question assuming that
the circle's center is there.

Since the circle's center is at (-2, 1), the left side of its equation is

                             (x + 2)² + (y - 1)²  =  .

The distance from the center to (-4, 1) is the circle's radius.

That distance is 2, so the right side of the equation is

                                                             4 .

Write a story about elevation that this expression could represent: 56 + (-56)
Ostrovityanka [42]

The correct statement that represents the expression is:

  • An object moves towards the east (positive direction )at a distance of 56m and west (negative direction) at the same distance, the total displacement of the object is 0m

Given the expression 56 + (-56).

  • We can see that this is an inverse rule where a value and its negative are added together.

Let us assume the values are distance covered by an object.

The correct statement that represents the expression is:

  • An object moves towards the east (positive direction )at a distance of 56m and west (negative direction) at the same distance, the total displacement of the object is 0m

This show that  56 + (-56) = 56 - 56 = 0

How many 3/4 pound packages can you make with 6.5 pounds of sunflower seeds?
xz_007 [3.2K]

Answer:

9 bags

Step-by-step explanation:

Weight each bag should be = 3/4 pound (0.75 pound)

Total weight of sunflower seeds available = 6.5 pounds

Number of packages made = 6.5/ 3/4

                                              = 8.66666666667

                                              = So 9 bags at the most

If you write 8, then  you wouldn't  be able to fit the other 0.5 pound and if you put 9, well you will have enough more space to put 6.5 pounds.

Hope this helps!!

Probability of landing on even # on a spinner; probability of rolling an odd # on a die
KonstantinChe [14]

Answer:

Spinner: 50%

Die: 50%

Step-by-step explanation:

Well for the spinner it depends on the amount of numbers it has,

in this case we’ll use 6.

So The probability of landing on the even numbers in a 6 numbered spinner.

2, 4, 6

3/6

50%

Your average die has 6 sides so the odd numbers are,

1, 3, 5

3/6

50%
