Question

Вирус,который попал в организм,к концу 30 минут делится на 2,каждый из которых к концу следующего интервала делится опять на 2 и т.д. Сколько вирусных частиц будет в организме через 4 часа,если после данного времени в организм попадёт ещё 10 вирусных частиц?

Answer 1

Ответ:

266

Объяснени

после 4 часов вируса будет 2^8=256

к ним добавится 10. получится 256+10=266

Answer 2

Calculation of Virus Particles in the Body

To calculate the number of virus particles in the body after 4 hours, we need to understand the rate at which the virus multiplies. According to the information provided, the virus divides into two particles every 30 minutes.

Let's break down the timeline and calculate the number of virus particles at each interval:

- 0 minutes: The initial number of virus particles is not specified. - 30 minutes: Each virus particle divides into two, resulting in twice the initial number of particles. - 60 minutes: Each of the particles from the previous interval divides into two, resulting in four times the initial number of particles. - 90 minutes: Each of the particles from the previous interval divides into two, resulting in eight times the initial number of particles. - 120 minutes: Each of the particles from the previous interval divides into two, resulting in sixteen times the initial number of particles. - 150 minutes: Each of the particles from the previous interval divides into two, resulting in thirty-two times the initial number of particles. - 180 minutes: Each of the particles from the previous interval divides into two, resulting in sixty-four times the initial number of particles. - 210 minutes: Each of the particles from the previous interval divides into two, resulting in one hundred twenty-eight times the initial number of particles. - 240 minutes (4 hours): Each of the particles from the previous interval divides into two, resulting in two hundred fifty-six times the initial number of particles.

Now, let's calculate the number of virus particles after 4 hours, given that 10 additional virus particles enter the body after this time:

- The initial number of virus particles is not specified. - After 4 hours, the number of virus particles will be 256 times the initial number. - In addition, 10 more virus particles will enter the body.

Therefore, the total number of virus particles in the body after 4 hours will be the product of 256 and the initial number of virus particles, plus 10:

Total number of virus particles = (256 * initial number) + 10

Unfortunately, the initial number of virus particles is not provided, so we cannot calculate the exact number.
