The order goes 4, 3, 2, 1
Answer:
Step-by-step explanation:
a. when t=0,h=3ft
c.t=47/32 sec
d.
time taken to fall 2301/64 ft=0*t+\frac{1}{2}*32*t^2
t^2=\frac{2301}{64*16}
t=\frac{\sqrt{2301}}{8*4}=\frac {47.97}{32}
total ~time=\frac{47+47.97}{32}=\frac{94.97}{32} sec
First you have to combine like terms, which are x and -.49x. You then get 0.51x. The equation now becomes .51x=5045.53. You then divide .51 on both sides. On the left you are left with x and on the right you are left with x=9893.19608.
X^2 + 9y^2 = 25
x^2/5^2 + (3y)^2/5^2 = 1
This represent an equation of an ellipse with cente at the origin, the horizontal major axis running from -5 to 5 and vertical minor axis running from -5/3 to 5/3
The third graph is the correct answer.
