The correct first step in finding the area of a base of a cylinder is to find the length of radius of the circular base.
Answer:
4
Step-by-step explanation:
The degree of a polynomial is the highest degree of a monomial contained within the polynomial. The degree of the monomial is the sum of the exponents on the variables. Example, the degree of -4x^6y is 6+1=7.
Example, the degree of 4x^8 is 8.
So the degree of 5x^4 is 4.
The degree of 3x^2 is 2.
The degree of 1 is 0 since there is no variable in this expression.
So the degree of 5 x^4 + 3 x^2 + 1 is 4.
Answer:
It is not.
Step-by-step explanation:
Using the Pythagorean Theorem, a squared + b squared = c squared, we get 25 + 64 = 100, and this is not true.
Inversely proportional means that the relation between y and x is of the form
y = c/x
where c is a constant.
Get c from knowing y=42 when x=6.
42 = c/6
Then c = 6*42 = 252
Therefore,
y = 252 / x
For x=9,
y = 252/9 = 28
