Answer:
Step-by-step explanation:
Identity used:
Now let us divide the modified expressions:
÷
we get:
The team plays 20 matches.
65% of the matches, the teams wins
= 20 * 0.65
= 13 matches
15% of the matches, the games ends in draw.
= 20 * 0.15
= 3 matches
The team is expected to lose in
= 20 - 13 - 3
= 4 matches

Step-by-step explanation:
Do you mean or ?
Use the formula where is the amplitude, is the phase shift, is the vertical shift, and the period is .
Assuming your first case is true, the amplitude would be , your period is , and your midline/vertical shift is .
Assuming your second case is true, everything but the vertical shift stays the same. It would be in this case.
Given:
The function is:
Where p(t) represents the number of milligrams of the substance and t represents the time.
To find:
The correct explanation for the number 0.25 and 500 in the given function.
Solution:
The general exponential function is:
...(i)
Where, a is the initial value and b is the growth/decay factor. If , then decay factor and if , then growth factor.
We have,
...(ii)
On comparing (i) and (ii), we get
, it means initial there are 500 milligrams of the substance.
, this value is less than 1, it means the substance is decreasing by a factor of 0.25.
Therefore, 0.25 means the substance is decreasing by a factor of 0.25 and 500 means the initial value of substance is 500 milligram.
√105
if u see its factor are only 3,5,7 so it cant be simplify
answer should be √105
B
