Answer:
b. A, D, and E
Step-by-step explanation:
This is the correct answer because a function cannot have replicated x-coordinates. All the other answer choices do, so you pick this one.
I am joyous to assist you anytime.
For the last missing box, I'd put 72.
Given a right triangle with the side lengths of legs = 9 and 13
For the required angle :
opposite side = 9
adjacent side = 13
so,
Time spent babysitting by Lucy = Tl = 4 hours
Time spent babysitting by Maria = Tm = x * 4 hours
Now we need to determine for what values of x is Tm > Tl
⇒ x * 4 > 4
⇒ x > 1
So for x > 1, Mary spends more time babysitting than Lucy does
Minimize
subject to
. The Lagrangian would be
and has partial derivatives
Setting each partial derivative to 0, we have
From the third equation, it follows that either
or
. In the second case, we arrive at a contradiction:
since both
and
must be non-negative, yet this would mean e.g.
. So it must be that
.
The first and second equations then tell us that
from which we obtain
.
Thus the points on the cone closest to (16, 6, 0) are
.
