You would need 31 Vans for everyone to be transported.
Answer:
1st blank=
2nd blank=
3rd blank= 
3*27=81
so 1*
=81
hence
=81
9*
= 81
=9
27*
=81
=3
Thus solved.

Answer:

Step-by-step explanation:
The current function of time is defined as follows:

where
is the charge function.
For the given charge function of time
we have the following current function:

In the problem it is proposed that
.
Examining the expression of
we obtained by deriving
with the expression proposed by the problem and comparing term by term:

We conclude that
and
.
Answer:

Step-by-step explanation:
Choices aren't given, so i will solve this equation and find the first positive x-intercept angle.
First, x-intercept means the x-cutting point of the graph. This occurs when y = 0. So we will solve the equation for x. Shown below:

Inverse Cotangent (ArcCot) of 0 is at
, so we can now solve for x:

So, the x-intercept is at x = pi/6
