Answer:
big wig me see
Step-by-step explanation:
A5 / a1 = r^4 = 324/4
So r^4 = 81
r = +/- 3
If r = 3 :-
S5 = 4 * (3^5-1) / (3-1) = 484
so r = 3 Answer
Answer:
A) =0
B)t= 0.45 seconds or t= 3.5 seconds
<em>If time is greater than 0.45 seconds then ball will reach height 12m and higher.</em>
Step-by-step explanation:
Given Equation:
h(t)= ------------------------------(Equation 1)
a) Equation to tell if ball reaches height of 12m . for that :
h= 12m
put in Equation 1.
12 =
or =12
or -12 = 0
=0
or = 0 -----------------------------------(Equation 2)
<em>This Equation tells if ball reaches height of 12m</em>
b) Does ball reaches height of 12m :
For that, the value of time can be found out from the equation above,
= 0
It can be solved using the quadratic formula:
t= 0.45 seconds or t= 3.5 seconds
If time is greater than 0.45 seconds then ball will reach height 12m and higher.
To convert a percentage to a decimal we divide it by 100. So, 5% = .05
To find the tax, multiply the cost by the tax rate
(.05)(11.20) = 0.56
Add this to the cost to get the total
$11.20 + $0.56 = $11.76
