Answer:

The constant of proportionality is equal to 2.5.

Step-by-step explanation:

The given equation is .

Now, let's assume y is proportional to x.

Mathematically, it can be written as,

Now, to eliminate the sign of proportionality by equal to, it is required to introduce a constant term. It can be represented as,

Now, compare the given equation with the above equation,

The above comparison concludes that the constant of proportionality is equal to 2.5.

Answer:

Step-by-step explanation:

The degree of a polynomial is determined by the largest exponent of a term within the polynomial.

Given

7x³ + 4x - 5 + 8 $x^{5}$

The term with the largest exponent is 8 $x^{5}$ with exponent 5

Thus the polynomial is of degree 5 → D

Answer:

The answer is 100.5 $in^{3}$ .

Step-by-step explanation:

To solve for the volume of the cylinder, use the cylinder volume formula, which is V = $\pi r^{2} h$ .

Next, plug in the information given from the problem, and the formula will look like V = $(\pi) (2 in^{2}) (8 in)$ .

Then, solve the equation, and the answer will be 100.5 $in^{3}$ .
