Answer:

Step-by-step explanation:
Total Surface Area of Cylinder = 
Given from the question, r = 7 cm and h = 15cm
Lets Substitute r and h into the formula to find the Total Surface Area of the cylinder.
Total Surface Area of Cylinder = 
Answer:
In the scenario in which you have declared a numeric array named numbers, and two of its elements are numbers[1] and numbers[5] you know that numbers[1] is smaller than numbers[5] and that there are exactly three elements between those two elements. Correct answer: a and c.
numbers[i] is the element of the array called numbers
Step-by-step explanation:
or
is very easy to graph.
Choose whatever value of
and use the same for
in the same coordinate. Repeat and strike a line through all the points.
Some examples of valid points would be:
,
,
and
.
Then, to graph
you have to look at it in terms of the equation of a line (
) and its parts.
In this case,
and
.
So, you choose any value for
and you solve to find its
counterpart.
I will start with
:

Now, we have a first coordinate:
.
Repeat with a different value:

It gives us the coordinates
.
Plot those into the graph and strike a line through them.
Wherever the two lines in your Cartesian Plane cross, that is the solution for both equations. It should be
.
You can check it by replacing
and
by "3" in both formulas and equating the values of
:

Your solution is worked out and checked to be correct.
PS: I am attaching a picture of the graph, so you can have a visual idea of what it should look like.
So, i think all you really need here is some definitions:
degree is the highest exponent that a polynomial has; a "fourth-degree" polynomial would have a highest exponent of 4.
a trinomial is a polynomial with 3 terms (tri means 3).
a cubic polynomial is a polynomial with an exponent of three.
terms are the values separated by signs in a polynomial; for example, in the binomial x - 1, both "x" and "-1" are terms.
with that info, an example of a fourth-degree trinomial is simply one with an exponent of 4 and 3 total terms: x⁴ + x² + 16 is one example, but there are maaaaaaaany examples you could create from it. x⁴ + x + 1 has a degree of 4 and three terms, so you can do whatever you want with it.
an example of a cubic polynomial with 4 terms could be x³ + x² + x + 1; x³ + 2x² + 27x + 119 is another. the most important thing for this one is that you list out x³, x², and x as well as a constant, because that's the only way to secure their placement in the polynomial without becoming like terms that combine and turn into fewer terms. you couldn't put two x² terms or multiple constants because they simplify into a single term.
