Answer:
Step-by-step explanation:
The vertical displacement function is 
, where 
is measured in meters and 
in seconds. Ball hits the ground when 
. That is:
Whose roots can be found by using the General Formula for Second-Order Polynomials:
Solutions of this polynomial are:
Only the first root is physically consistent.
Lets do this step by step.
1st.) what is 15% as a decimal
15% = 0.15
2nd.) multiply
220 x 0.15 = 33
3rd) we add that 33 and 220 since this its asking for the increase
220 + 33 = 253
Answer = 253
Answer:
zero property
Step-by-step explanation:
if it equals zero its zero property
y/x = k
6.4/4 = 1.6
11.2 / 7 =1.6
16/10 = 1.6
20.8 /13 =1.6
This is a direct variation and the constant is 1.6
y=1.6x
To find the sum:
Therefore the answer is a^3+12a^2+14a+5.
Hope it helps!
