PLEASE HELP Zane has built a large firework type rocket to shoot off north table mountain. Zane wants to know the height the rocket will reach and the time until the rocket hits the ground. he knows the force of gravity is -10m/sec^2, the initial velocity of the rocket is 50m/s and the height of north table mountain is 400 meters. he also knows the rocket flight will be parabolic which can be modeled by a quadratic function. What's the quadratic function in standard form? And how many seconds till it hits the ground?

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 )

C. because 6÷3=2 so 3 is half of six so 3/6
