Given the equation, what is the center and radius of the circle? (X-2) ^2+ (Y+11)^2=100

LekaFEV [45]

Answer:

Center: (2, -11)

Radius: 10

Step-by-step explanation:

(x - 2)² + (y + 11)² = 100

(x - h)² + (y - k)² = r²

-------------------------------

x - 2 = 0

+2 +2

x = 2

------------

y + 11 = 0

-11 -11

y = -11

------------------------------

r² = 100

r = √100

r = 10

----------------------------

Center: (h, k)

Radius: r

-------------------------------

Center: (2, -11)

Radius: 10

I hope this helps!

While playing games on a particular smart phone, 1% of the battery is drained every five minutes of game play. The battery start

Nostrana [21]

Answer:

B(75) represents the percent of battery full after 75 minutes of game play

Step-by-step explanation:

Let m represent the number of minutes of game play. If 1% of the battery is drained every five minutes of game play, then after m minutes of game play $\dfrac{m}{5}\%$ was drained.

The battery starts off at 80% full. After m minutes the battery will have

$B(m)=80-\dfrac{m}{5}$

percent full.

When $m=75$ minutes, then

$B(75)=80-\dfrac{75}{5}=80-15=65\%.$
