Alarge explosion causes wood and metal debris to rise vertically into the air with an initial velocity of 160 feet per second. the function h(t) = 160 t − 16 t 2 160t-16t2 gives the height of the falling debris above the ground, in feet, t t seconds after the explosion.
a. use the given polynomial to find the height of the debris 2 second(s) after the explosion.
b. factor the given polynomial completely.

a) The debris was 256 feet  into the air after 2 seconds of the explosion.

b)

Step-by-step explanation:

We are given the following in the question:

Initial Velocity =  160 feet per second

The above function gives the height in feet and t is seconds after the explosion.

a) Height of the debris 2 second(s) after the explosion.

We put t = 2 in the above function

Thus, the debris was 256 feet  into the air after 2 seconds of the explosion.

b) Factor the polynomial

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .
