s=−11.8(t−1.2)2+17The equation models the horizontal distance, s, in centimeters, of a particular image on a computer screen from the left-hand edge of the screen, t seconds after appearing. If the image moves in from the left-hand edge of the screen during an on-screen animation, how far to the right does the image travel?Choose 1 answer:(A) 1.2 centimeters(B) 5.2 centimeters(C) 17 centimeters(D) 34 centimeters
Q. s=−11.8(t−1.2)2+17The equation models the horizontal distance, s, in centimeters, of a particular image on a computer screen from the left-hand edge of the screen, t seconds after appearing. If the image moves in from the left-hand edge of the screen during an on-screen animation, how far to the right does the image travel?Choose 1 answer:(A) 1.2 centimeters(B) 5.2 centimeters(C) 17 centimeters(D) 34 centimeters
Plug in t=0: First, let's plug t=0 into the equation to find the initial position of the image.s=−11.8(0−1.2)2+17
Calculate initial position: Calculate the initial position:s=−11.8(−1.2)2+17s=−11.8×1.44+17s=−17.072+17s=−0.072cm
