The length of the side of the small triangle is 4...the side length of the large triangle is 9 (5+4), not 5. It should be correctly written as 4/6 = 9/x
Since all sides are equal, all angles equal 60 degrees
3y= 60
y=20
2x=60
x=30
Answer: A
Step-by-step explanation:
![\left(\frac{f}{g} \right)(x)=\frac{f(x)}{g(x)}=\frac{\sqrt[3]{4x}}{2x+3}](https://tex.z-dn.net/?f=%5Cleft%28%5Cfrac%7Bf%7D%7Bg%7D%20%5Cright%29%28x%29%3D%5Cfrac%7Bf%28x%29%7D%7Bg%28x%29%7D%3D%5Cfrac%7B%5Csqrt%5B3%5D%7B4x%7D%7D%7B2x%2B3%7D)
The denominator cannot equal 0, so

Answer:
180feet
Step-by-step explanation:
Given the function that models the height of a ball
s(t) = 144 + 48t − 16t^2.
At maximum height, the velocity is zero ie. ds/dt = 0
ds/dt = 48 - 32t
0 = 48 - 32t
48 = 32t
t = 48/32
t = 1.5secs
Get the maximum height
s(t) = 144 + 48t − 16t^2.
s(1.5) = 144 + 48(1.5)-16(1.5)^2
s()1.5) = 144 + 72 - 16(2.25)
s(1.5) = 144 + 72-36
s(1.5) = 180 feet
Hence the maximum height attained by the ball is 180feet
