What is the equation used to find the nth term of the arithmetic sequence:
-8, -5 -2, 1, 4

Answers

Answer:

        aₙ = 3n - 11

Step-by-step explanation:

The equation of the nth term of the arithmetic sequence is: [tex]a_n =a_1+d(n-1)[/tex]

d = -5 - (-8) = - 5 + 8 = 3

a₁ = -8

Therefore:

               [tex]a_n =-8+3(n-1)\\\\a_n =-8+3n-3\\\\a_n =3n-11[/tex]

What is the equation of a circle with center (−3, 0) and radius 20?

Answers

Answer:

(x + 3)^2 + y^2 = 20^2

Step-by-step explanation:

If the center is (-3, 0), then the standard equation of a circle, (x - h)^2 + (y - k)^2 = r^2 becomes (x + 3)^2 + (y - 0)^2 = 20^2, or

The volume of the rectangular prism is 24 inches cube.

What is volume?

Volume is the scalar quantity of any object that specified occupied space in 3D.

For example, the space in our room is referred to as volume.

Volume has units of cube example meter³,cm³, etc.

The volume of cuboid = length × height × width.

The volume of the cube = side³.

Given the rectangular prism with a bunch of small cubes whose volume is 1/4 inches³.

Number of small cubes = 8 × 4 × 3 = 96

The volume of the complete prism = Volume of 1 cube × the Number of small cubes.

The volume of the complete prism = 1/4 × 96

The volume of the complete prism = 26 inch³.

Hence "The volume of the rectangular prism is 24 inches cube".
