Ageometric sequence is defined recursively by an = 20an-1. the first term of the sequence is 0.01. which of the following is the explicit formula for the nth term of the sequence? a.0.01 • 20n+1 b.0.01 • 20n c.20 • 0.01n d.20 • 0.01n-1 e.0.01 • 20n-1

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 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.
