Answer:
Step-by-step explanation:
FIND SALE PRICE
= $230 - ($230*20%)
= $230 - $46
= $184
OR
= $230 * (100%-20%)
= $230 * 80%
= $184
*use the method you're most comfortable with or that your teachers prefer
FIND TOTAL WITH TAX
= $184 + ($184 * 11.5%)
= $184 + $21.16
= $205.16
ANSWER: The shoes with discount and taxes cost $205.16.
Hope this helps! :)
Answer:
<h2>(0.3, -18.45).</h2>
Step-by-step explanation:
We need to recur to the extreme value theorem, which states: "If a function is continuous on a closed interval, then that function has a maximum and a minimum inside that interval".
Basically, as the theorem states, if a dunction is continuous, then it has maxium or minium.
In this case, we have a quadratic function, which is a parabola. An important characteristic of parabolas is that they have a maximum or a minium, but they don't have both. When the quadratic term of the fuction is positive, then it has a minium at its vertex. When the quadratic term of the function is negative, then it has a maximum at its vertex.
So, the given function is
, where the quadratic term is positive, so the functions has a minimum at
, where
and
, let's find that point
<h3>

</h3><h3>

</h3><h3 /><h3>Therefore, the minium of the function is at (0.3, -18.45).</h3>
3/12 is actually a quarter which is equal to 0.25. It certainly isn't an irrational number, but is indeed a rational one.
By definition irrational numbers cannot be represented using single fractions.
