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)=160-144
h(3)=16
Therefore, the height of the ball after 3 secs of dropping is 16 feet.
Answer:
The interest generated will be $ 51.20.
Step-by-step explanation:
To determine the compound interest on the account with 0.01% interest rate in 5 years compounded quarterly with an initial deposit of $ 1,000, the following calculation must be performed:
1,000 x (1 + 0.01 / 4) ^ 4x5 = X
1,000 x (1 + 0.0025) ^ 20 = X
1,000 x 1.0025 ^ 20 = X
1,000 x 1.05120 = X
1,051.20 = X
1,051.20 - 1,000 = 51.20
Therefore, the interest generated will be $ 51.20.
