The product is equal zero if one of the factors is equal zero.Therefore:
<span>100 = 0.046s^2 - 0.199s + 0.264
0 = 0.046s^2 - 0.199s - 99.736
s= 48.77691127... or -44.45082431 (reject)
The car's speed was approximately 48.8 mph.</span>
Add the 2x values and divide by two, then add the 2y values and divide by 2
answer is (-2,½).
