Answer:
-9
Step-by-step explanation:
<u>Given </u><u>:</u><u>-</u><u> </u>
- A Arithmetic sequence -5 , -14 , -23 ...
And we need to find out the common difference of the Arithmetic sequence . The common difference of a Arithmetic sequence is the number which is added to a term to obtain the next term of the sequence . And it can be obtained by subtracting the consecutive terms.
<u>Sequence</u><u> </u><u>:</u><u>-</u><u> </u>
-5 , -14 , -23
<u>Common</u><u> difference</u><u> </u><u>:</u><u>-</u><u> </u>
CD = -14 -(-5) = -14+5=-9
CD = -23-(-14) = -23+14=-9
<u>Hence </u><u>the</u><u> </u><u>common</u><u> difference</u><u> </u><u>is </u><u>(</u><u>-</u><u>9</u><u>)</u><u> </u><u>.</u>
We have that
y=-3x²<span>+5x+11
we know that
the equation of the parabola in standard form can be expressed in one of the following two ways
y=ax</span>²+bx+c
<span>the parabola opens up if a is positive and opens down if a is negative
and
x=ay</span>²+by+c
the parabola opens right if a is positive and opens left if a is negative
<span>
in this problem
the equation is of the form
</span>y=ax²+bx+c<span>
a=-3
so
the parabola opens down
using a graph tool
see the attached figure
the vertex of a parabola is a maximum
the answer is
</span>the parabola opens down
