Answer:
the answer is b . 0.4405 which is 0.44
Step-by-step explanation:
just divide and subtract
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>
Answer:
Step-by-step explanation:
Equation of a circle:
The equation of a circle with center 
is given by:
In which r is the radius.
Center (-14, -3)
This means that 
So
Passes through the point (-5,3),
This means that when 
. We use this to find the radius squared. So
So, the equation of the circle is:
1 group of 5 and 1 of 8
draw 5 dots and 8 and count them together
Answer:
Step-by-step explanation:
x + (x+30) + (2x) = 180
4x = 150
x = 37.5°
x+30 = 67.5°
2x = 75°
