A sprinter travels a distance of 200 m in a time of 18.53 seconds. What is the sprinter's average speed rounded to 4 sf?

Hell . what are the solutions to `10x^2 - 38x - 8 = 0`? is this when i find the factors and use the numbers within the factors to determine the zeros? i hope that made sense lol

Write the summation to estimate the area under the curve y = 1 + x2 from x = -1 to x = 2 using 3 rectangles and right endpoints

50 points~ ! i have to turn this in tomarrow
