Answer:
Step-by-step explanation:
1- It's known that shifting(called translation), reflection and rotation operations on th function would let us manipulate it as we like, and taking the square root function
would let us to start graphing from the desired point in the xy-plane by using shifting operations on it.
2- Taking the minus of the square root function
would reflect the function over x-axis so the function would be decreasing from 0 to infinity.
3- Then, adding 4 to x in the square root
would make the domain of the function to start from
or
(by adding 4 to both sides).
4- Finally, the function of the domain (-4,
) is
.
I hope that I helped, and i'm sorry for any English mistakes(I'm not English speaker) .
We know that two complements add up to 90.
Let's call the smaller angle x and the larger y.
3x = y
x + y = 90
We can use simple substitution.
x + 3x = 90
4x = 90
x = 22.5
Then, since we know that 3x=y, we can find the larger angle.
3*22.5 = 67.5
The difference between their swim times was 0.055 seconds.
