When Sanchez left his house this morning, his cell phone was 30% charged and it then started to lose 3% charge for each hour thereafter. Write an equation for the function B(t), representing the charge remaining in Sanchez's battery, as a percentage, t hours after he left his house.

The equation that represents the battery charge in Sanchez's phone as a percentage t hours after he left his house is B(t) = 30 - 3*t.

Step-by-step explanation:

The initial state of the battery on Sanchez's phone is 30% so in time t equals zero the battery should be at that value and as time progresses the battery should lose battery charge at a rate of 3% for each hour. We can write this in an equation form by taking the initial state and subtract it by the rate multiplied by the value of time. We have:

B(t) = 30 - 3*t

The equation that represents the battery charge in Sanchez's phone as a percentage t hours after he left his house is B(t) = 30 - 3*t.

私たち一人一人には、善と悪のビジョンがあります。私たちは人々に彼らが良いと思うものに向かって動くことを奨励しなければなりません...誰もが善と悪についての彼自身の考えを持っており、彼が彼らを想像するときに善に従いそして悪と戦うことを選ばなければなりません。それは世界をより良い場所にするのに十分でしょう。
