The expression below represents the number of trees planted by an environmental agency after t years.
interpret the meaning of the expression.
a.
the initial number of trees planted by the agency is 1,500, and the growth rate is 2% per year.
b.
the initial number of trees planted by the agency is 2, and the growth rate is 1.5% per year.
c.
the initial number of trees planted by the agency is 2, and the growth rate is 15% per year.
d.
the initial number of trees planted by the agency is 1,500, and the growth rate is 20% per year.

a

step-by-step explanation:

its wrong

answer-

the equation that models this pattern is

solution-

a researcher placed a petri dish with 32,000 bacterial cells. one hour after being placed in the vacuum chamber, the number of cells in the petri dish had halved. another hour later, the number of cells had again halved.

this can be represented as exponential decreasing function,

where,

putting the values,

y-intercept means, where x=0, so

the coordinate of this poin will be (0, 32000)

this means when x=0 or at the starting of the research, the number of bacteria cells was 32000.

after 3 hours, number of bacteria cells will be,

the   coordinate of this point will be (3, 4000)
