Answer:

Step-by-step explanation:

r = 9 cm

h = 10 cm

Volume of cone = (1/3)πr²h

=\frac{1}{3}*3.14*9*9*10\\\\=3.14*3*9*10\\

= 847.8 cubic cm

Which expressions are completely factored? Select each correct answer. 32y10−24=8(4y10−3) 18y3−6y=3y(6y2−2) 16y5+12y3=4y3(4y2+3)
laila [671]

Answer:

Option A and Option C

Step-by-step explanation:

Option A: 32y^{10}-24 = 8(4y^{10}-3) This is completely factored as 8 is the Highest Common Monomial factor

Option B: 18y^{3}-6y = 3y(6y^{2}-2) This is not completely factored as 2 is still a common factor of 6y2 and -2.

Option C: 16y^{5}+12y^{3}=4y^{3}(4y^{2}+3) This is completely factored as 4y2 is the Highest Common Monomial factor

Option D: 20y^{7}+10y^{2} = 5y(4y^{6}+2y) This is not completely factored as 2y is still a common factor of 4y6 and 2y.

So the options that are completely factored are Option A and Option C

A sequence is represented by the formula an=-5+a(n-1). If a4 = 20, what is the 6th term in the sequence?
Citrus2011 [14]

Answer:

<u>10</u>

Step-by-step explanation:

Formula :

  • aₙ = -5 + aₙ₋₁

Finding a₅ :

  • a₅ = -5 + a₄
  • a₅ = -5 + 20
  • a₅ = 15

Finding a₆ :

  • a₆ = -5 + a₅
  • a₆ = -5 + 15
  • a₆ = <u>10</u>
