There are 1500 bees in a colony. each month, the number of bees decreases by 12%. there are 800 flowering plants in a garden. each month, 25 flowering plants are removed.

part a: write functions to represent the number of bees and the number of flowering plants throughout the months. (4 points)

part b: how many bees are in the colony after 6 months? how many flowering plants are in the garden after the same number of months? (2 points)

part c: after approximately how many months is the number of bees and the number of flowering plants the same? justify your answer mathematically. (4 points)

(10 points)

n=6.77 months (exactly)

n=7 months (nearest integer, less accurate)

Step-by-step explanation:

A) The initial number of bees in a colony is 1500. Each month the number of bees decreases by 12% which means each month we must factor by (1-0.12)=0.88

So the number of bees as a function of n months is  

1500*0.88*0.88...0.88 (n times)

The initial number of flowering plants is 800 and there are 25 fewer of them each month. It can be written as

B) After 6 months (n=6) there will be

And there will be

flowering plants

C) We want to know the value of n that make B = P:

Rearranging

This equation cannot be solved by exact procedures, we must approach the answer or use any numerical method to solve for n

The best value to solve the equation is n = 6.77 months in which case

And flowering plants

If we wanted to use only integers for n, then we should use the nearest integer to our previous value, that is, n=7. In this case,

flowering plants

answer: -2+√x,-2-√x

i hope this , i don't know if you're looking for a pair or not.

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1
