Answer:
<em>B. 11 - 6 = 5</em>
Step-by-step explanation:
Median: 9.5
Lower Quartile: 6
Upper Quartile: 11
Interquartile Range: upper quartile - lower quartile = answer
Step-by-step explanation:
If a cannonball is shot directly upward with a velocity of 160 ft per second. Its height as a function of time is given by :
.......(1)
t is in seconds
(a) Velocity is given by :
Acceleration is given by :

(b) For maximum height put 
i.e.

Put t = 5 s in equation (1). So,

(c) When the ball reaches ground, its height is equal to 0. So,
h(t) = 0

Hence, this is the required solution.
<em>g(x)</em> = <em>x</em>² - <em>x</em> - 6
so
<em>g</em> (-4) = (-4)² - (-4) - 6 = 16 + 4 - 6 = 14
When <em>g(x)</em> = 6, we have
6 = <em>x</em>² - <em>x</em> - 6
<em>x</em>² - <em>x</em> - 12 = 0
Solve for <em>x</em>. We factorize this easily as
(<em>x</em> - 4) (<em>x</em> + 3) = 0
which gives
<em>x</em> - 4 = 0 <u>or</u> <em>x</em> + 3 = 0
<em>x</em> = 4 <u>or</u> <em>x</em> = -3
