Hi!
The 18 passes to the other side dividing.
18 t = 72
t = 72 / 18
t = 4
Hope this helps, good studies! :)
Thickness of human hair - 9*10^1
Distance from earth to satellite - 2.8*10^13
Width of an apple - 1.1*10^1
Length of a tour bus - 4*10^0
The answer is 43 hope this helps
They multiplied 3 by itself 4 times, so it’s 3^4
Answer:
.
Step-by-step explanation:
Let the
-coordinate of
be
. For
to be on the graph of the function
, the
-coordinate of
would need to be
. Therefore, the coordinate of
would be
.
The Euclidean Distance between
and
is:
.
The goal is to find the a
that minimizes this distance. However,
is non-negative for all real
. Hence, the
that minimizes the square of this expression,
, would also minimize
.
Differentiate
with respect to
:
.
.
Set the first derivative,
, to
and solve for
:
.
.
Notice that the second derivative is greater than
for this
. Hence,
would indeed minimize
. This
value would also minimize
, the distance between
and
.
Therefore, the point
would be closest to
when the
-coordinate of
is
.
