In 2000, an invasive plant species covered 0.2% of an island. for the 5 years that followed, the area covered by the plant tripl
ed every year.
A student said "That means that about half of the island's area was covered by the plant in 2005!"
do you agree with his Statement? explain your reasoning.
1 answer:
Answer:
The statement is correct
see the explanation
Step-by-step explanation:
we know that
The equation of a exponential growth function is equal to

where
y is the area covered by the plant in percentage
x is the time in years since 2000
r is the rate of change
a is the initial value
In this problem we have


substitute the values


In the year 2005

substitute the value of x in the exponential function

48.6% is about 50%
therefore
The statement is correct

Step-by-step explanation:
3:5...added = 8
3/8(2000) = 6000/8 = 750 use brand x aspirin <===
5/8(2000) = 10000/8 = 1250 do not use brand x aspirin
I good with D because i think it’s for Sure the right answer
The answer is
<span>D. y = 4cos(-x) - 2
proof
cosine is an even function, it means cos(-x) = cosx
so </span>y = 4cos(-x) - 2 = y = 4cos(x) - 2
