A potato gun is a device made out of plastic pipe that launches a potato using compressed air. They can be great fun, and even educational for physics and math, as this question illustrates. A potato launched by a particular potato gun has a height described by h ( t ) = − 16 t 2 + 124 t + 4 h(t)=-16t2+124t+4. When is the potato 224 feet in the air?

The potato is 224 feet in the air after 2.75 second on the way up and after 5 seconds on the way back down.

Step-by-step explanation:

Given :  A potato launched by a particular potato gun has a height described by  .

To find : When is the potato 224 feet in the air?

Solution :

When the potato is 224 feet in the air i.e.

Substitute in the equation ,

Applying quadratic formula,

Here, a=4, b=-31 and c=55

The potato is 224 feet in the air after 2.75 second on the way up and after 5 seconds on the way back down.

anser is a

step-by-step explanation:

negitive slope

∠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.
