Which of the following is a geometric sequence? a
3, 6, 9, 12, … b
11, 15, 19, 23, … c
4, -16, 64, -256, … d
50, 25, 0, -25, …

answer: it's a

step-by-step explanation:

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°

the clb she uses is a driver, so its a 2/5 chance she hits a 180-189 yard shot

step-by-step explanation:

it is rigid.; it is isometric. ; the size is preserved.

step-by-step explanation:

a translation is called an isometry; these are transformations that preserve congruence between pre-images and images.

they are also called rigid transformations, as the only thing that can happen to a pre-image is that it is moved or turned, not stretched or shrunk.

since congruence is preserved, the size is preserved.
