Answer:

12π  inches.

Step-by-step explanation:

Area = π r^2 = 36π  (given).

So r^2 = 36  giving r = 6.

The exact circumference = 2 π  r

= 2 π * 6

= 12π.

Answer:

12πin

Step-by-step explanation:

From the question given, the area of the circle is 36πin^2

Recall:

Area of circle = πr^2

36π = πr^2

Divide both side by π

36 = r^2

Take the square root of both side

r = √36

r = 6in

Circumference of a circle = 2πr

= 2π x 6

= 12πin

Find the distance between the pair of points and then round your answer to the nearest tenth.
Travka [436]

Answer:

d = 9.4 units (nearest tenth)

Step-by-step explanation:

Given the distance formula, d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}, distance between (-4, 5) and (4, 0) is calculated as follows:

Let (-4, 5) = (x_1, y_1)

(4, 0) = (x_2, y_2)

d = \sqrt{(4 - (-4))^2 + (0 - 5)^2}

d = \sqrt{(8)^2 + (- 5)^2}

d = \sqrt{64 + 25}

d = \sqrt{89}

d = 9.4 units (nearest tenth)

The equation x²– 8x – 5 = 0 can be transformed into the equation (x - p)² = q, where p and q are real numbers. What are the valu
Juliette [100K]

The form (x - p)^2 = q is the form that completing the square will leave us with.

---Add 5 to both sides

x^2 - 8x = 5

---Divide the b term by 2, and square it. Then, add that number to both sides.

-8/2 = -4

(-4)^2 = 16

x^2 - 8x + 16 = 5 + 16

x^2 - 8x + 16 = 21

---Factor!

(x - 4)^2 = 21

p = 4

q = 21

Hope this helps!! :)

Prove that the conjecture is false by providing a counter example.
Bas_tet [7]

Answer:

Any negative number would be a counterexample.

Step-by-step explanation:

Since negative numbers get smaller as you multiply them by a larger number, this would prove this conjecture false.
