Answer:
Step-by-step explanation:
We have been given that the area 
(in square meters) of a circular algae colony with radius r meters is given by 
. The radius 
(in meters) after t minutes is given by 
. We are asked to write the formula for the area 
(in square meters) of the algae colony after t minutes.
This problem is based on composite functions, in which function represents radius of circle after t minutes.
To write the formula for the area (in square meters) of the algae colony after t minutes, we need to substitute 
in area formula .
Therefore, our required formula would be .
Answer:
20 Minutes
Step-by-step explanation:
First find out how many he eats per minute. 17/5 = 3.4
Then multiply 3.4 by all the answers until you get the right answer.
Oooo ok
I don’t now true this or no
But answer is 13
Answer:
5/36
Step-by-step explanation:
Probability is the outcome that a event will occur
Probability = Expected outcome/Total outcome
Since two sided dice are rolled, the total outcome will be expressed as;
Total outcome = 36
Since we are to find the probability that the sum is 8, the values that gives a sum of 8a re;
(2,6)(6,2), (5, 3), (3,5), (4, 4)
The expected outcome = 5
Probability = 5/36
Hence the probability that the sum is 8 is 5/36
