Answer:
(2) (100, 300)
Step-by-step explanation:
One wave can be divided on 4 parts, as show on the picture.
Since a length of one whole wave equals 400, a length of each part is nanometers.
The height of the wave is decreasing on the second and on the third part, hence over the interval (100, 300).
Answer:
Step-by-step explanation:
We are asked to find the tangent line approximation for near
.
We will use linear approximation formula for a tangent line of a function
at
to solve our given problem.
Let us find value of function at as:
Now, we will find derivative of given function as:
Let us find derivative at
Upon substituting our given values in linear approximation formula, we will get:
Therefore, our required tangent line for approximation would be .
Given:
Principal (P)= $1,000
Rate of interest (R)= 4% = 0.04
Simple interest (I)= $100
To find:
The time for which she deposits $1000 into a savings account at 4% simple interest.
Solution:
The formula for simple interest is
On substituting P=1000, R=0.04 and I=100 in the above formula, we get
Divide both sides by 40.
Therefore, the required time is 2.5 years.
