Answer:
2070m/s
Step-by-step explanation:
frequency=900HZ
Wavelength=2.3m
now,
speed of wave= frequency × wavelength =900×2.3
=2070m/s
ANSWER
Answer:
B. ( - 2, - 5)
Step-by-step explanation:
Coordinates of point A are ( - 2, - 5).
the answer 1 7/8 i got that by doing 3/8 x 5/1 which equal 15/8 and simplifies to 1 7/8
According to the information given, the parabolic equation which describes the path of the water from the hose to the top of her plants is:
- The coefficients are .
<h3>What is the equation of a parabola?</h3>
The<em> equation of a parabola</em>, of vertex (h,k), is given by:
In this problem:
- The highest point the water reached was 8 feet, and it landed on the plants 10 feet from where she was standing, hence the vertex is (10,8), that is, .
Then:
Both the nozzle of the hose and the top of the flowers were 4 feet above the ground, hence point (4,4), when is part of the function, which is used to find a.
Hence, the equation is:

Volume=length times width times height
given
volume=576
length=12
width=6
height=?
576=12 times 6 times ?
576=72 times ?
divide both sides by 72
8=?
