What is the nthnth term of the arithmetic progression, −3,−8,−13,...-3,-8,-13,...? a.2+5n2+5n
b.8+5n8+5n
c.2−5n2-5n
d.8−5n8-5n

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,

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°

you would need to also lose 1 point for each of the other outcomes for it to be fair.
