Answer:
n = (1/9)u
Step-by-step explanation:
This is a direct variation relationship of the form
n = ku
For n = 2, u = 18.
2 = k * 18
We solve for k.
k = 2/18
k = 1/9
Now we use k in the equation of the relationship.
n = (1/9)u
Answer:
Since I cant say which answer due to no graph, I'll tell you How to do so.
Step-by-step explanation:
if it is A, then the there is at least one angle or line length that is not the same. To find the area of a grided shape, use the traingle theorm of a^2+b^2=c^2.
if it is B, that meants moving the shape to the other will result in a perfect fit. Be sure to find if all side lengths are the same as that means that the shape IS congrouent, as equal side length means equal angles. However, it will not be this choice if the shape is mirrored to the other
A rotation and tranlastion means it is flipped either upside down or up and moved to the shape.
D, a reflection, which means its the opposite. Like a mirrored shape. Then you move it.
It is A because you are adding 3 to in if you were to subtract then it will go down not up.

Answer:
h = 110.24 m
Step-by-step explanation:
It is given that,
A rock is thrown up from the ground at a velocity of 84 feet per second. The formula
gives the rock's height in feet after t second.
We need to find the maximum height of the rock. For maximum height put ![\dfrac{dh}{dt}=0](https://tex.z-dn.net/?f=%5Cdfrac%7Bdh%7D%7Bdt%7D%3D0)
So,
![\dfrac{d( -16t^2 + 84t)}{dt}=0\\\\-32t+84=0\\\\t=\dfrac{84}{32}\\\\t=2.62\ s](https://tex.z-dn.net/?f=%5Cdfrac%7Bd%28%20-16t%5E2%20%2B%2084t%29%7D%7Bdt%7D%3D0%5C%5C%5C%5C-32t%2B84%3D0%5C%5C%5C%5Ct%3D%5Cdfrac%7B84%7D%7B32%7D%5C%5C%5C%5Ct%3D2.62%5C%20s)
Put t = 2.62 s in the equation of height. So,
![h = -16(2.62)^2 + 84(2.62)\\\\h=110.24\ m](https://tex.z-dn.net/?f=h%20%3D%20-16%282.62%29%5E2%20%2B%2084%282.62%29%5C%5C%5C%5Ch%3D110.24%5C%20m)
So, the maximum height of the rock is 110.24 m.
