The graph of sin function is a curve as shown below:
Now, Sin 2Ф , where Ф =
or sin 2Ф = 2 ×
or sin 2Ф =
Ans, sin π/2 = sin 180/2 = sin 90 = 1
Thus, the curve has maximum at 90.
Answer:
6 to 40
Step-by-step explanation:
add all of the marbles which will give you the total
45/35＝54/54－x
9/7＝54/54－x
9(54－x)＝378
54－x＝42
x＝12
Hope my answer helped u :)
Answer:
Ratio of present ages of Sonal and Manoj = 7:5
Let us consider the ages of Sonal and Manoj to be 7x yrs. and 5x yrs. respectively.
After 10 years, ratio of their ages = 9:7
A/q, 7x+10/5x+10 = 9/7
or 9 (5x+10) = 7 (7x+10)
or 45x + 90 = 49x + 70
or 49x - 45x = 90 - 70
or 4x = 20
or x = 20/4 = 5 .
Therefore, present age of Sonal = 7x yrs. = 7 x 5 yrs. = 35 yrs.
present age of Manoj = 5x yrs. = 5 x 5 yrs. = 25 yrs.

You helped me before so thank you
Answer: 62 - T
Step-by-step explanation:
I think it is 62 - T because Stephanie is 62 inches and it says that her brother is shorter which I believe it means that you have to subtract.
