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
Answer:
<em>Kaya found 25 shells on the beach yesterday.Today she found 25 more shell. She sorted all the shells into 5 pile.Which equation can be used to find how many shells are in each pile? </em>
<em>A.s=(25+25)÷5 </em>
<em>B.s=25÷5 </em>
<em>C.s=(25+25)-5</em>
Equation A can be used to find the number of shells in each piles.
Step-by-step explanation:
Given:
Number of shells Kaya found day before =
Number of shells she found today =
According to the question:
She sorted it into piles meaning we have to equally put them in each pile, for this we have to divide the total number of shells.
Let the number of shells in each pile =
And total number of shells =
So,
The number of shells in each pile.
⇒
⇒
⇒
From equation where,
gives the same answer.
Then option A is the right choice.
