Object Height. Suppose an object is thrown straight up from the ground. The height after t seconds is given by the formula h(t) = -3³ + 89² +229 (a) The time in seconds when the object reached the highest point was Note: Round to 4 digits after the decimal point, if rounding is required O None of the other answers O 229 s 19.7778 s O 44.5 s Oos O 14.8333 s (b) The height is maximized at the critical point x = a because the second derivative test found Of(a) = 0 Or(a) was positive to the left of xa and negative to the right (f" (a)=0 Of(a) was negative to the left of x = a and positive to the right Of" (a) > 0 Of" (a) <0
