Answer:
7y=x
Step-by-step explanation:
Answer:
Number of terms: 2
Degree: 1
Step-by-step explanation:
✔️A term can either be a coefficient with a variable, a variable, or a constant.
In the polynomial given, 10y + 2, there are two terms:
First term is a coefficient with a variable = 10y
Second term is a constant = 2
The two terms are: 10y and 2
✔️Degree of a polynomial is the highest exponents possessed by any of its term.
10y has an exponent of 1.
The degree of the polynomial therefore will be 1
At
, you have
The trick to finding out the sign of this is to figure out between which multiples of
the value of
lies.
We know that
whenever
, and that
whenever
, where
.
We have
which is to say that
, an interval that is equivalent modulo
to the interval
.
So what we know is that
corresponds to the measure of an angle that lies in the third quadrant, where both cosine and sine are negative.
This means
, so
is decreasing when
.
Now, the second derivative has the value
Both
and
are negative, so we're essentially computing the sum of a negative number and a positive number. Given that
for
, and
for
, we can use a similar argument to establish in which half of the third quadrant the angle
lies. You'll find that the sine term is much larger, so that the second derivative is positive, which means
is concave up when
.
