Answer:
205 litres
Step-by-step explanation:
Given:
Volume of water is given as:
(in litres)
<em>m</em> is the time in minutes spent filling water in Eduardo's pool.
To find:
Volume of water in the pool after the water is filled for
minutes.
Solution:
Here, volume of water in the Pool (in litres) is given by the equation:
....... (1)
Where m is the time for which Eduardo fills the pool.
Here, we are also given that
m =
minutes =
minutes
And we have to find the value of V after
minutes.
Let us put the value of m as
minutes in the equation (1) to find the value of V.

So, the volume of water in the pool after
minutes is <em>205 litres.</em>

Eva follows the bond market and often purchases bonds issued by Sanden Research Labs. Last year, she purchased three such bonds in January, one in May, and four in June, then sold them all in November. Sanden Research Labs bonds were selling at 78.430 in January, 95.652 in May, 86.220 in June, and 87.454 in November. If each bond she purchased had a par value of $500, how much profit did Eva gain from buying and selling these bonds?</span>

Answer:
A minimum of 16 rows are needed
Step-by-step explanation:
Here, we want to calculate the number of rows minimum that could seat 382 people in rows of 24 seats.
Mathematically, what we need to do here is to make a division.
We shall divide the number of people by the number of seats in a row so that we can get the number of rows needed.
Mathematically, that would be; 382/24 = 15 22/24
We are looking at a minimum number.
So we can see that 15 rows will be filled, with an extra 22 seats in the next row leaving only 2 seats in the next row unoccupied.
So we can see that the minimum number of rows required is 16 rows
Cos Ф - cos Ф.sin² Ф
sin² Ф = 1 - cos² Ф
cos Ф - cos Ф( 1-cos² Ф) = cos Ф - cos Ф - cos³ Ф = cos³ Ф
cos Ф - cos Ф.sin² Ф = cos³ Ф
