The graph shows the vertical displacement y, in centimeters, that a weight bouncing from a spring would achieve if there were no friction, for a given number of seconds, x. (a) what is the weight’s maximum displacement? (b) from its resting position, how long does it take the weight to bounce one direction, then the other, and then return to its resting position? (c) what are the period and the amplitude of the function? (d) what is the graph’s frequency and what does it indicate in this situation? (e) how is the weight moving during the time period x = 4 to x = 5?

total amount to be paid = $19.5

step-by-step explanation:

given ,

original price = $25.99

discount = 25%

discount amount = 25% of original price

discount amount = 25/100   * 25.99

discount amount = $6.49

hence , the total amount to be paid = original price - discount amount

                                                            = $25.99 - $6.49

                                                            =$19.5

total amount to be paid = $19.5

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°
