<span>t takes 5 1/3 minutes for light from the sun to reach earth. The Moon is closer to earth, so it,s light reaches earth faster about 5 19/60 minutes faster than from the sun. How long does light from the moon take to reach earth.</span>
Answer:
Option a.
Step-by-step explanation:
In the given triangle angle A is a right angle so triangle ABC is a right angled triangle.
Opposite side of right angle is hypotenuse. So, CB is hypotenuse.
From figure it is clear that CA is shorter that segment BA.
All angles are congruent to itself. So angle C is congruent to itself.
We know that, if an altitude is drawn from the right angle vertex in a right angle triangle it divide the triangle in two right angle triangles, then given triangle is similar to both new triangles.
So, triangle ABC is similar to triangle DBA if segment AD is an altitude of triangle ABC.
Therefore, the correct option is a.
Answer:
x = 3.4
Step-by-step explanation:
Given the graphs of 2 functions, then the solutions to both are at their points of intersection, that is
where f(x) = g(x)
There are 3 possible points of intersection to f(x) = g(x)
The one on the list , however, is at x = 3.4
Answer:
Step-by-step explanation:
a) In 1.2 seconds, sound will travel a distance of ...
(1.2 s)(340 m/s) = 408 m
This is the round-trip distance, so the reflecting surface is half that distance away.
The other side of the canyon is 204 m away.
__
b) In 5 seconds, the sound will travel a distance of ...
(5 s)(340 m/s) = 1700 m
This is the one-way distance, so the lightning is about 1700 m away.
Given:
The quadratic equation is:
