Answer:

B. a₁ = -6, aₙ = aₙ₋₁ + 4

Step-by-step explanation:

From the given sequence we see that:

Common difference is 4

Find the first term:

a₁ + 3*4 = a₄
a₁ + 12 = 6
a₁ = -6

The recursive formula for this sequence is:

a₁ = -6, aₙ = aₙ₋₁ + 4

Correct choice is B

What is the volume of the cylinder if the height is 2x+7 and the radius is x-3

shusha [124]

Answer:

Therefore the volume of the cylinder $=\pi(2x^3-5x^2-24x+63)$ cubic units

Step-by-step explanation:

Given height of a cylinder is (h) =2x+7

and radius (r)= x-3

Volume of the cylinder = $\pi r^2 h$

$=\pi (x-3)^2(2x+7)$

$=\pi (x^2-6x+9)(2x+7)$

$=\pi (2x^3-12x^2+18x+7x^2-42x+63)$

$=\pi(2x^3-5x^2-24x+63)$ cubic units

Therefore the volume of the cylinder $=\pi(2x^3-5x^2-24x+63)$ cubic units

Match each system of linear equations with the correct number of solutions

kondaur [170]

Answer:

Hey there!

The first equation has no solutions, as it is parallel lines.

The second equation has infinitely many solutions, as it is basically the same line, and the two lines intersect at infinite points.

The third equation is just one solution.

Let me know if this helps :)
