Answer:
2
Step-by-step explanation:
Take the absolute value of the lowest y value.
So
Take the absolute value of highest y value.
Add those two together and divide by two.
So the amplitude is 2
To find the original amount, you divide the product by the percentage.
112.79 / 0.15 ≈ 751.933 (the 3's repeat infinitely).
To check your answer, multiply 751.933 by 0.15.
751.933 * 0.15 = 112.78995 ≈ 112.79
Answer:H2+Br2-->2HBr
Step-by-step explanation:
The amount of atoms on the left side must be equal to the amount of atoms on the right side for each element.
On the left you got 2xH and 2xBr.
This means you must have the same amount on the right.
2HBr =2xH + 2xBr
Answer:
-25
Step-by-step explanation:
2x + 50 = 0
2x = 0 - 50
= -50
x = -50 / 2
= -25
