Answer:
No, because 70% of a class of 30 students would be 21, not 24
Step-by-step explanation:
Answer:
The parametric equations for the tangent line are
:
x = Cos(10) - t×Sin(10)
y = Sin(10) + t×Cos(10)
z = 20 + 2t
Step-by-step explanation:
When Z=20:
Z=2t=20 ⇒ t=10
The point of tangency is:
r(10)= Cos(10) i + Sin(10) j + 20 k
We have to find the derivative of r(t) to get the tangent line:
r'(t)= -Sin(t) i + Cos(t) j + 2 k
The direction vector at t=10 is:
r'(10)= -Sin(10) i + Cos(10) j + 2 k
So, the equation of the tangent line is given by:
x = cos 10 -t×Sin(10)
y = sin 10 + t×Cos(10)
z = 20 + 2t
Well if the data is related to 8 cm by 12cm(it means 4cm of radius and 12 of height)and you already have pi so what you need is to use the formula <span>V=π*r^2*(h/3) and replace the data. After you do this you can see that the closest is 339 cm3. Hope this helps a lot </span>
