A projectile is launched from ground level with an initial velocity of v 0 feet per second. Neglecting air resistance, its height in feet t seconds after launch is given by s= -16t^2 + v 0 t. Find the time(s) that the projectile will (a) reach a height of 80 ft and (b) return to the ground when v0 = 112 feet per second. (a) Find the time(s) that the projectile will reach a height of 86 ft when v 0= 112 feet per second. Select the correct choice below and, if necessary, fill in the answer box to complete your choice.

d? maybe

step-by-step explanation:

5.5

step-by-step explanation:

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

step-by-step explanation:

given   that triangle lno is congruent to triangle lnm.

we have to fill up the blanks in the given question.

according to above order of congruency   kept in mind we can say that

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

ln ≅ ln due to common in both.

hence, by sas congruency,

the side angle side rule   states that if two sides and the included angle of one triangle are congruent to another triangle, then these two triangles are congruent.

hello :

70y^8 + 30y^6 = 2 ( 35 y^8 + 15y^6)

the lenght is : 35 y^8

the width is : 15y^6
