For this case we have an equation of the form:
 h (t) = - (1/2) * a * t ^ 2 + vo * t + h0
 Where,
 vo: initial speed
 a: acceleration:
 h0: initial height.
 We have the following equation:
 h (t) = - 16t2 + 19t + 110
 Therefore, the initial velocity is:
 vo = 19 feet / s
 Answer:
 
The initial velocity when the rock is thrown:
 
vo = 19 feet / s

Nitella [24]

Answer:

P = 300

r = 0.15

n = 12

A(t) = 300(1.0125)^12t

Step-by-step explanation:

Given that:

Total credit taken for book purchase = $300

Annual Interest rate = 15% compounded monthly

Time or period = 4 years

P(1 + r/n)^nt

P in the expression above means the principal amount which is the total credit spent on book purchase = $300

r = annual interest rate on Emma's account = 15% = 15/100 = 0.15

n = number of compounding times per period ; loan which compounds monthly = number of months in a year = 12

Hence,

P = $300 ; r = 0.15 ; n = 12

Substituting into the equation :

P(1 + r/n)^nt

Simplified expression written in terms of t:

Final amount, A after t years

A(t) = 300(1 + 0.15/12)^12t

A(t) = 300(1 + 0.0125)^12t

A(t) = 300(1.0125)^12t
