Find the area of a circle that has a circumference of 12π in.

Answer:

3/29

Step-by-step explanation:

area of total rectangle is 12x8 or 96 sq cm

area of shaded square is 9

96 - 9 = 87 sq cm, which is area of unshaded region

9 out of 87 is the probability of selecting a point in the shaded region, which simplifies to 3/29

Answer:

lol i see r o b l o x

Step-by-step explanation:

Rectangle = bxh

thats is 96

the we know that the square in the middle is 3x3x3x3 or 81

then subtract the two which is 15

The function g(x) is a discrete function. It is continuous between -7 to -2, -2 to 3, and 3 to 8. And the open circle at -7, -2, 3, and 8. And the jump of the g(x) is 4 units after every interval.

The function is an expression, rule, or law that defines the relationship between one variable to another variable. Functions are ubiquitous in mathematics and are essential for formulating physical relationships.

[tex]g(x) = \left\{\begin{matrix} \ \ \ \ 6, -7 < x < -2\\\ \ \ 2, -2 < x < 3\\-2, 3 < x < 8\\\end{matrix}\right.[/tex]

The function g(x) is a discrete function. It is continuous between -7 to -2, -2 to 3, and 3 to 8. And the open circle at -7, -2, 3, and 8.

And the jump of the g(x) is 4 units after every interval.

Step-by-step explanation:

Answer:

Step-by-step explanation:

1. (a + b)2 = a2 + 2ab + b2; a2 + b2 = (a + b)2 − 2ab

2. (a − b)2 = a2 − 2ab + b2; a2 + b2 = (a − b)2 + 2ab

3. (a + b + c)2 = a2 + b2 + c2 + 2(ab + bc + ca)

4. (a + b)3 = a3 + b3 + 3ab(a + b); a3 + b3 = (a + b)3 − 3ab(a + b)

5. (a − b)3 = a3 − b3 − 3ab(a − b); a3 − b3 = (a − b)3 + 3ab(a − b)

6. a2 − b2 = (a + b)(a − b)

7. a3 − b3 = (a − b)(a2 + ab + b2)

8. a3 + b3 = (a + b)(a2 − ab + b2)

9. an − bn = (a − b)(an−1 + an−2b + an−3b2 + ··· + bn−1)

10. an = a.a.a . . . n times

11. am.an = am+n

12. am

an = am−n if m>n

= 1 if m = n

= 1

an−m if m<n; a ∈ R, a 6= 0

13. (am)n = amn = (an)m

14. (ab)n = an.bn

15. a

b

n

= an

bn

16. a0 = 1 where a ∈ R, a 6= 0

17. a−n = 1

an , an = 1

a−n

18. ap/q = √q ap

19. If am = an and a 6= ±1, a 6= 0 then m = n

20. If an = bn where n 6= 0, then a = ±b

21. If √x, √y are quadratic surds and if a + √x = √y, then a = 0 and x = y

22. If √x, √y are quadratic surds and if a+ √x = b+ √y then a = b and x = y

23. If a, m, n are positive real numbers and a 6= 1, then loga mn = loga m+loga n

24. If a, m, n are positive real numbers, a 6= 1, then loga

25. If a and m are positive real numbers, a 6= 1 then loga mn = n loga m

26. If a, b and k are positive real numbers, b 6= 1, k 6= 1, then logb a = logk a

logk b

27. logb a = 1

loga b where a, b are positive real numbers, a 6= 1, b 6= 1

28. if a, m, n are positive real numbers, a 6= 1 and if loga m = loga n, then

What number must you add to x² + 16x = 3 to complete the square 64: Option C

You should be aware that a perfect square is a term that has two common factors

The given equation is x² + 16x = 3

To make the equation a perfect square, Add the square of half of the coefficient of s to both sides

This is to say that (16/2)² = 8² = 64

The equation becomes x²+16x+64 = 3+64

Then you can factorize the equation and simplify the right hand side

Answer:

Area= 70x^3y^2

Perimeter = 20x^2 + 14 xy^2

Step-by-step explanation:

Area is just multiplying the length and width, I multiplied the constants first which gets us 70 then multiplied the variables, they combine however only the x's can be multiplied to each other which results in 70x^3y^2 .  The perimeter you just multiply the length by two and the width by two, they are separate because the variables when added to each other do not combine.

Step-by-step explanation:

The equations of the corresponding circles can be any equation only have to satisfy the  general equation for  circle .

A circle is the set of all points in a plane at a given distance (called the radius ) from a given point (called the center.)

We know that the general equation for a circle is

[tex]( x - h )^2 + ( y - k )^2 = r^2[/tex],

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

According to the question

The equation of circle given is

[tex]x^{2} + y^{2} = 1[/tex]

Center at origin

i.e

(h,k) = (0,0)

and radius = 1 unit

Now ,

By changing changing center (h,k) and radius of equation it will give following equations

h                      k                       r                            equation of circle

0                       1                       3                        [tex]( x - 0 )^2 + ( y - 1 )^2 = 3^2[/tex]

2                       2                       3                        [tex]( x - 2 )^2 + ( y - 2)^2 = 3^2[/tex]

1                        1                        1                         [tex]( x - 1 )^2 + ( y - 1 )^2 = 1^2[/tex]

-2                      -1                       2                        [tex]( x +2 )^2 + ( y + 1 )^2 = 2^2[/tex]

3                       2                       1                         [tex]( x - 3 )^2 + ( y - 2 )^2 = 1^2[/tex]

-5                      1                        3                        [tex]( x +5 )^2 + ( y - 1 )^2 = 3^2[/tex]

Hence, the equations of the corresponding circles can be any equation only have to satisfy the  general equation for  circle .
