Your height and color of the sidewalk. the table could be different colors sidewalks can be and different heights. or anything would be fine! just make an example with two things that do not correlate.
Step-by-step explanation:
The equation is y = -x - 4.
We have that
<span> points (−20, 21) and (0, 0)
Let
A----> </span>(−20, 21)
B-----> (0, 0)
using a graph tool
see the attached figure
step 1
find the distance AB
<span>applying the Pythagorean theorem
</span>
AB²=20²+21²--------> 841---------> AB=√841-------> 29
AB=29 units
cos <span>Θ=20/29-------> 0.6897
</span>
the angle <span>Θ belong to the second quadrant
therefore
the cos</span><span>Θ is negative
the answer is
the cos </span>
Θ is -0.6897
Answer:
Step-by-step explanation:
v=u+at
38.9=13.2+21.5 t
21.5 t=38.9-13.2
21.5 t=25.7
t=25.7/21.5≈1.195 s
