The equation for a circle with center (h, k) is (x - h)^2 + (y - k)^2 = r^2. If a circle is modeled by the equation x^2 + (y + 6

Ronch [10]

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

x^2 + (y + 6)^2 = 100

we can rewrite this as

(x-0)^2 + (y - -6)^2 = 10^2

the center is (0,-6) and the radius is 10

Answer:

653.45 cm^2

Step-by-step explanation:

The volume of a cylinder can be found using:

v=pi r^2 h

We know the radius is 4, and the height is 13, so we can substitute them in

v=pi (4^2)(13)

v=pi (16)(13)

v=pi 208

v=653.451272

Rounded to the nearest hundredth

v=653.45

So the volume is 653.45 cm^3

A single card is drawn from a standard 52-card deck. Let B be the event that the card drawn is a black, and let F be the event

Galina-37 [17]

Answer:

0.6154 or 61.54%

Step-by-step explanation:

The joint probability P(B′∪F) is given by the sum of each individual probability minus the intersection between both probabilities (red face cards).

$P(B'\cup F) = P(B')+P(F)-P(B'\cap F)$

The inverse probability of a card being black is also the probability of a card being red, which is 26 in 52. There are 12 face cards in a 52-card deck, 6 of which are not black, therefore:

$P(B'\cup F) = \frac{26}{52} +\frac{12}{52}-\frac{6}{52}\\P(B'\cup F) = \frac{32}{52} = \frac{8}{13} =0.6154$
