Answer:
The correct option is B.
Step-by-step explanation:
It is given that the surface area of an oil spill gets 131% larger every day, represented by the function
Where x is number of days.
On the first day, it covered an area of 21 square meters. It means the initial area is 21 square meters.
The function is defined as
Where is initial value and b is growth factor.
It means the function of new area is the product of initial area and increasing area function. The required function is
Therefore option B is correct.
Answer:
T(t) = 3sin((t-5)π/30)
Step-by-step explanation:
5 minutes after Thomas ties it on, the torque is zero and increasing. So, the sine function is shifted right 5 minutes. The maximum value is 3, so that is the multiplier of the sine function. The period is 60 minutes, so the coefficient of t is (2π/60) = π/30. The function you want is ...
T(t) = 3sin((t-5)π/30)
Answer:
Hence the 3.28 %or 2/61 of total work will be done .
Step-by-step explanation:
Given:
The pecan crops are harvested for friday and saturday (2days)
To find :
What fraction these 2 days corresponds to the harvesting days?
Solution;
The pecan crops are growing in America in state of Georgia
and consider that in months of October and November pecan crop becomes mature .
Hence the harvesting period is of 2 months considerably .
The month of October and November days are 31 and 30 .
Hence the Total days of harvesting are 61 days.
In these days total Pecan crops will be harvested.(100% work in 61 days)
Now the farmer harvest for 2 days only .
Required fraction=2/61
=0.0327869
=3.28%
Depending upon the crop field and planting answer will vary
But 3.28 % of total work will be done in 2 days on harvesting
