Let me complete your question:

<span>Find the missing coefficient in the equation of the line that passes thru given point. Ax+3y=5, (2-1)?
</span>
Is this the question?

 <span>A= 4 

4x+3y=5 

you plug in your points to solve it. 

A(2) + 3(-1) = 5 
2A + -3 = 5 
2A= 8 
A = 4

A cylinder and cone have the same height and radius. The height of each is 5 cm, and the radius is 2 cm. Calculate the volume of
never [62]

Answer:

The volume of a cylinder is 62.8 cm and the volume of a cone is 20.9 cm³ .

Step-by-step explanation:

Formula

Volume\ of\ a\ cylinder = \pi r^{2} h

Volume\ of\ a\ cone = \pi r^{2} \frac{h}{3}

Where r is the radius and h is the height .

As given

A cylinder and cone have the same height and radius. The height of each is 5 cm, and the radius is 2 cm.

\pi = 3.14

Thus

Volume\ of\ a\ cylinder =3.14\times 5\times 2\times 2

                                             = 62.8 cm³

Thus the volume of a cylinder is 62.8 cm³ .

Volume\ of\ a\ cone = 3.14\times 2\times 2\times frac{5}{3}

Volume\ of\ a\ cone =\frac{5\times 3.14\times 2\times 2}{3}

Volume\ of\ a\ cone =\frac{62.8}{3}

                                        = 20.9 (Approx) cm³

Thus the volume of a cone is 20.9 cm³ .

Therefore the volume of a cylinder is 62.8 cm and the volume of a cone is 20.9 cm³ .

which algebraic expression is a polynomial with a degree of 4? a: 5x4 b: x5 – 6x4 14x3 x2 c :9x4 – x3 – d:2x4 – 6x4
dybincka [34]

Answer: the option C. c) 9x⁴– x³– ...

Explanation:

1) A polynomial of one variable is an expression of the kind:

a_nx^n+a_{n-1}x^{n-1}+a_{n-2}x^{n-2}+...+a_1x+a_0

2) The order of the polynomial is the highest exponent of the variable, this is n

3) When the expression has one term it is called a monomial, when the expression has two terms it is called a binomial, when the expression has 3 terms it is called a trinomial.

Usually expressions of that kind with two or more terms are referred as polynomial, but one term is referred as monomial.

4) For the given expressions you have:

a) 5x⁴: it is a monomial (one term), which is usually not referred as polynomial properly.

b) x⁵ – 6x⁴ + 14x³ + x²: it is a polynomial with degree 5 (the highest power).

c) 9x⁴– x³– ... : altough the expression is incomplete, assuming that the next terms are monomials with degree less than 4, then this is a polynomial with degree 4, and is the right answer choice.

d) 2x⁴ – 6x⁴: since both terms have the same power, they can be simplified into one term, - 4x⁴, and it is a monomial.
