Which is true about the polynomial –3xy2 + 5x?y?

It is a binomial with degree 3

Explanation:

It has two terms: (−3xy2) and (5x2y) → it is a binomial

The degree of an expression is the largest sum of exponents of variables for any term in the expression.

−3xy2=−3x1y2 has a sum of exponents of variables =3

5x2y=5x2y1 also has a sum of exponents of variables =3

→ the expression has degree 3

see explanation

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
