Answer:
first, u need to know the formula for compound interest, which is:
where A is the final amount
P- initial amount
r- percent compounded(interest)
and
n- number of years
so
we have
3.8/100 = 0.038
1+0.038 =1.038
1.038^4 = 1.160885573136
475 * 1.160885573136 = 551.4206472396
approximately $551.42
Answer:
Step-by-step explanation:
Since we have been given height of triangle as 8 and length of its base as 3. We can use similar triangles to express the base of the smaller triangle in terms of h.
The height of the smaller triangle will be
Let x be the base of the smaller triangle. Therefore, using similar triangles, we can set the ratios of corresponding sides of the two triangles equal to each other as shown below:
Now, we can express the area of the small rectangular strip of length x and thickness Dh as shown below:
Therefore, the required Riemann sum can be expressed as:
The required areas can be expressed as:
Rest of your answers are correct. :)
