refer to the following information.
A botanist is cultivating a rare species of plant in a controlled environment and currently has 3000 of these plants. The population of this species that the botanist expects to grow next year, Nnext year, can be estimated from the number of plants this year, Nthis year, by the equation below.
The constant K in this formula is the number of plants the environment is able to support.
The botanist would like to increase the number of plants that the environment can support so that the population of the species will increase more rapidly. If the botanist’s goal is that the number of plants will increase from 3000 this year to 3360 next year, how many plants must the modified environment support?
refer to the following information.
A botanist is cultivating a rare species of plant in a controlled environment and currently has 3000 of these plants. The population of this species that the botanist expects to grow next year, Nnext year, can be estimated from the number of plants this year, Nthis year, by the equation below.
The constant K in this formula is the number of plants the environment is able to support.
According to the formula, what will be the number of plants two years from now if K = 4000 ? (Round your answer to the nearest whole number.)
