Dead leaves accumulate on the ground in a forest at a rate of 3 grams per square centimeter per year. at the same time, these leaves decompose at a continuous rate of 85 percent per year. a. write a differential equation for the total quantity q of dead leaves (per square centimeter) at time t:

The rate of change of mass density (g/cm²) per year is +3 - 0.85×q. Thus, your equation is

... q'(t) = 3 - 0.85q(t)

hope this : )

the length of o'p' is .

step-by-step explanation:

it is given that the quadrilateral m'n'o'p' is the image of quadrilateral mnop after dilation.

the center of dilation is origin and the scale factor is 1.5.

in dilation the image and preimge are similar figures. it means the sides of image and preimage are proportional.

the scale factor is defined as

the scale factor is 1.5.

multiply both sides by op.

note: if the value of op is given, then multiply the value of op with 1.5 to get the length of side o'p'.

therefore length of o'p' is .
