Answer: Cosine
This is because cosine involves the adjacent over hypotenuse
cos(angle) = adjacent/hypotenuse
Hello :
<span>D= 3sin(8 pi t) - 2
t=0 : D =3sin(0) - 2 = 0-2 = - 2
</span><span>objects position at t= 0 is : (0 , -2)</span>
The volume formula of a sphere is 4/3 Pi R^3
To figure this out, we must cube the radius (multiply 3 times).
2 x 2 x 2 = 8 (4 x 2).
Now we must multiply 8 by 3.14
8 x 3.14 = 25.12
Since we have gotten those out of the way, we now have to multiply 25.12 by 4/3.
4/3 x 25.12 = 33.51
33.5 in ^3 is your answer since we used volume.
Hope this helps!
I really don’t know the answer .
The answer is C, (1,-4) the y automatically cancels out and makes 10x=10. X=1 and x is always first so it automatically makes C the answer.
