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

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

Answer:

$sin \theta =\cfrac{7}{8}$

Step-by-step explanation:

Using the given identity, find the required value as per following steps:

$(sin x)^2 + (cos x)^2 = 1$

$(sin x)^2 = 1 - (cos x)^2$

$sinx=\sqrt{ 1 - (cos x)^2}$

$sin \theta = \sqrt{1-(\cfrac{\sqrt{15}}{8})^2 } = \sqrt{1-\cfrac{15}{64} } =\sqrt{\cfrac{49}{64} }=\cfrac{7}{8}$
