FOIL

Front term ( 15y) multiplied with the Last (4) then multiply the Front term (15y) with the Inside term (-17y). Now, multiply the other Inside term (-2) by the Last term (4) and the Inside term (-17).

Multiply each number by both of the other numbers in the other set of ( ).

the height of a ball dropped from a 160 foot building after t seconds is represented by h(t)=160-16t^2.how high will the ball be

alekssr [168]

Answer:

The height of the ball after 3 secs of dropping is 16 feet.

Step-by-step explanation:

Given:

height from which the ball is dropped = 160 foot

Time = t seconds

Function h(t)=160-16t^2.

To Find:

High will the ball be after 3 seconds = ?

Solution:

Here the time ‘t’ is already given to us as 3 secs.

We also have the relationship between the height and time given to us in the question.

So, to find the height at which the ball will be 3 secs after dropping we have to insert 3 secs in palce of ‘t’ as follows:

$h(3)=160-16(3)^2$

$h(3)=160-16 \times 9$

h(3)=160-144

h(3)=16

Therefore, the height of the ball after 3 secs of dropping is 16 feet.
