Answer:
√1
Step-by-step explanation:
If you do the fractions by squaring them then you get fractions that equal 1:
5/13^2 = 25/169
12/13^2 = 144/169
144/169 + 25/169 = 169/169 = 1
√1
A.)
<span>s= 30m
u = ? ( initial velocity of the object )
a = 9.81 m/s^2 ( accn of free fall )
t = 1.5 s
s = ut + 1/2 at^2
\[u = \frac{ S - 1/2 a t^2 }{ t }\]
\[u = \frac{ 30 - ( 0.5 \times 9.81 \times 1.5^2) }{ 1.5 } \]
\[u = 12.6 m/s\]
</span>
b.)
<span>s = ut + 1/2 a t^2
u = 0 ,
s = 1/2 a t^2
\[s = \frac{ 1 }{ 2 } \times a \times t ^{2}\]
\[s = \frac{ 1 }{ 2 } \times 9.81 \times \left( \frac{ 12.6 }{ 9.81 } \right)^{2}\]
\[s = 8.0917...\]
\[therfore total distance = 8.0917 + 30 = 38.0917.. = 38.1 m \] </span>

Probability<span> is a type of ratio where we compare how many times an outcome can occur compared to all possible outcomes. What is the </span>probability<span> to get a 6 when you roll a die? A die has 6 sides, 1 side contain the number 6 that give us 1 wanted outcome in 6 possible outcomes.</span>
