Ordered pair is
<u>Step-by-step explanation:</u>
We have the following inequalities:
and . In order to find ordered pair would be a solution on the graph .Let's solve both inequalities , and will take common solution from both of them !
and , which implies:
⇒
⇒
⇒
putting value of x in both inequalities we get,
and
and
and
Hence at x = and y = above inequalities are satisfied. ∴ Ordered pair is
The answer is 39.2 m/s
We need the velocity of the rock as it reaches the ground, and it is its final velocity. Since it is the free fall, we also must take into consideration gravitational acceleration (a). Therefore, the formula for the final velocity (v2) is:
v2 = v1 + at
v2 - the final velocity
v1 - the initial velocity
a - gravitational acceleration
t - time
As you can see, the distance in this case is not relevant.
It is known:
v1 = 0 m/s (since it was dropped)
a = 9.8 m/s²
t = 4 s
Therefore, the velocity of the rock as it reaches the ground (v2) is:
v2 = 0 + 9.8 · 4 = 39.2 m/s
Answer:
answer is A
Step-by-step explanation:
The formula for circumference of a circle using diameter is pi times "d". "d" means diameter. 3.14 x 16= 50.24
Answer:
81.6 inches squared
Step-by-step explanation:
The formula for calculating all parallelograms is Area+=base*height.
The height is given to you, 6.8, the base of the figure is also given, 12.
Now all you have to do is to multiply.
That would get you to 81.6.
(When asked for area of parallelogram, the length of any line other than the height and base is not needed)
hoped this helped!
Answer:
Step-by-step explanation:
P = $ 800
r = 4%
t = 2 years
= $64
Money in the bank after 2 years = 800 + 64 = $864
