Answer:

Yes; because P(S & E)= P(E) • P(E).

Step-by-step explanation:

P(S)=530/1600 = 0.33, P(E)= 1523/1600= 0.95, and P(S & E)= 498/1600= 0.31 = (0.33)(0.95)

. A hawk flying at a height of 60 feet spots a rabbit on the ground. If the hawk dives at a speed of 55 feet per second, how
Vladimir [108]

Answer:

The hawk reaches the rabbit at t=4.3 sec

Step-by-step explanation:

Let

h ----> is the height in feet

t ----> is the time in seconds

v ---> the initial velocity in feet pr second

s ----- is the starting height

we have

h=-16t^{2} +vt+s

when the hawk reaches the rabbit the value of h is equal to zero

we have

v=55\ ft/sec

s=60\ ft

substitute

0=-16t^{2} +55t+60

Solve the quadratic equation by graphing

The solution is t=4.3 sec

see the attached figure

You can see what I mean in the attachment

So to mark other points we follow the following steps

  1. Connect OA
  2. With OA as base, make angle of 72°. Say th new line is OB.
  3. Similarly, do for the rest of them
  4. This is a cyclic pentagon
