Question

(Паскаль) Гриб за сутки увеличивает свою массу на 40%. Через сколько суток масса гриба увеличится в 2,5 раза, если первоначально масса гриба составляла А?

Answer 1

Где то через 2,5 суток

Answer 2

Calculation of the Increase in Mushroom Mass

To calculate the number of days it takes for the mass of a mushroom to increase by 2.5 times, given an initial mass of A and a daily increase of 40%, we can use the following formula:

Final Mass = Initial Mass * (1 + Daily Increase)^Number of Days

In this case, the daily increase is 40% or 0.4, and the final mass is 2.5 times the initial mass. Let's solve for the number of days:

2.5 * A = A * (1 + 0.4)^Number of Days

To isolate the number of days, we can divide both sides of the equation by A and take the logarithm:

log(2.5) = log(1.4)^Number of Days

Taking the logarithm base 10 of both sides:

log(2.5) = Number of Days * log(1.4)

Now we can solve for the number of days:

Number of Days = log(2.5) / log(1.4)

Let's calculate the number of days using this formula.
