Aball is thrown in the air from the top of a building. its height, in meters above ground as a function of time, in seconds, is given by h ( t ) = − 4.9 t 2 + 29 t + 18 h(t)=-4.9t2+29t+18. how long does it take to reach maximum height? round to the nearest hundredth of a second.

So you have to multiply the numbers inside the parentheses then divide what you get and then after that you’re going to multiply your answer and then get your answer than divided it then after that answer you at eight and then you then

Answer: d. 39 cmin the diagram, the approximate length of the minor arc de is 39 centimetres.step-by-step explanation: the formula for the length of an arc in a circle is as displayed below.let the length of the minor arc de = xx = 2( pi )r × angle of sector / 360°from this, we will substitute the values given from the problem into the formula to obtain the length of the minor arc de.x = 2( pi )r × angle of sector / 360°r = radius = 25cmpi as an approximate value = 3.14angle of sector = 120°x = 2( 3.14 )( 25 ) × 120° / 360°x = 157 × 1 / 4x = 39.25x = 39 ( rounded to the nearest whole number as an approximate value )
