Answer:
$1.5 / Ibs
$1.3 / Ibs
Step-by-step explanation:
In order for us to find out unit price of strawberries we do the following calculation for each grocery store
total price/total kgs = unit price of strawberry.
$2.99/2lbs= $1.5 per Ibs
$3.88/3lbs= $1.3 per Ibs
The above answers are rounded off to one decimal place
Answer:
7.07
Step-by-step explanation:
Answer:
Show that if
for some
where
, then by Rolle's Theorem
for some
. However, no such
exists since
for all
.
Note that Rolle's Theorem alone does not give the exact value of the root. Neither does this theorem guarantee that a root exists in this interval.
Step-by-step explanation:
The function
is continuous and differentiable over
. By Rolle's Theorem. if
for some
where
, then there would exist
such that
.
Assume by contradiction
does have more than one roots over
. Let
and
be (two of the) roots, such that
. Notice that
just as Rolle's Theorem requires. Thus- by Rolle's Theorem- there would exist
such that
.
However, no such
could exist. Notice that
, which is a parabola opening upwards. The only zeros of
are
and
.
However, neither
nor
are included in the open interval
. Additionally,
, meaning that
is a subset of the open interval
. Thus, neither zero would be in the subset
. In other words, there is no
such that
. Contradiction.
Hence,
has at most one root over the interval
.
I think the answer would be 123.4
