Sorry this was for math which of the following terms best describes a condition in which a quantity decrease at a rate that is proportional to the current value of the quantity a. positive slopeb. negative slopec. exponential decayd. exponential growth

Option

c

Explanation:

Given that the quantity decreases at a rate that is proportional to the current value of the quantity.

This can be expressed as

rate of change of y = derivative of y

=y'=-ky

where k is the constant of proportionality

This differential equation is linear and can be solved by separation of variables

Integrate both sides

Rise to power e

where A=e^C

Hence this is exponential decay

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.
