Identify a1 and r for the geometric sequence
a1 =
r =

a₁ = - 256 , r = -

Step-by-step explanation:

The nth term of a geometric sequence is

= a₁

Given

= - 256 , then by comparison

a₁ = - 256 and r = -

answer: answer: d) v= 1/6 bh  

step-by-step explanation:

since according to the given question,   a pyramid is placed inside a prism.

step-by-step explanation:

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
