The center of a circle is at (4,-3) and it’s radius is 3 units, which point lie on the circle

Mathematics
1 answer:
sergey [27]3 years ago
4 0

Answer:

Any set of (x , y) whose distance from (4, -3) is 3 units lies on the circle.

Step-by-step explanation:

To find the distance , use the formula

distance = \sqrt{(x_2 - x_1)^2 + (y_2 -y_1)^2}

If distance < 3, (x, y) lies inside the circle.

If distance > 3, (x, y) lies outside the circle.

If distance = 3 (x, y) lies on the circle.

Calculate 6 P 6 note n p r equals n Over N - r​
Murrr4er [49]

Answer:

7

Step-by-step explanation:

n! Might be 7, and n might be 6. r might also be 6. So 6 - 6= 0! = 1

Four different sets of objects contain 2,5,6 and 7 objects respectively how many unique combinations can be formed by picking on
dusya [7]

Answer:

420 unique combinations.

Step-by-step explanation:

Fundamental counting principle:

States that if there are p ways to do a thing, and q ways to do another thing, and these two things are independent, there are p*q ways to do both things.

One object from each set:

2 from one set, 5, 6 and 7 by others. Sets are independent, so, by the fundamental counting principle:

2*5*6*7 = 10*42 = 420

420 unique combinations.

mestny [16]

9514 1404 393

Answer:

  5/8

Step-by-step explanation:

The area of the smaller circles is proportional to the square of the ratio of their diameters. The two smallest circles have diameters equal to 1/4 the diameter of the largest circle. Hence their areas are (1/4)^2 = 1/16 of that of the largest circle.

Similarly, the medium circle has a diameter half that of the largest circle, so its area is (1/2)^2 = 1/4 of the are of the largest circle.

The smaller circles subtract 2×1/16 +1/4 = 3/8 of the area of the largest circle. Then the shading is 1-3/8 = 5/8 of the area of the largest circle.
