You just add 42,000 and 3,433.52 to get the answer, which is, 45,433.52
The answer is C because if u use the menstratle method you can see
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.
