The answer is 1/8 because he shaded obe out of eight parts
Answer:
all real numbers
Step-by-step explanation:
f(x) = 2|x − 1| + 3
The domain is what values can we put in for x
There is no limit to what we can put in for x
therefore the domain is all real numbers
F(x) = -2 (x-9)2 + 14
= -4(x-9) + 14
= -2 [ 2(x-9) -7 ]
= -2 (2x -18 -7)
= -2 (2x -25)
Answer:
<em>The ball takes 5 seconds to hit the ground</em>
Step-by-step explanation:
The equation to model the height of a golf ball in time t is:

There are two moments when the height is zero: At launch time and when it hits the ground. To find the last time, we equate:

Factoring out t:

It gives us two solutions:
t=0

Solving:


t = 5 sec
Thus, the ball takes 5 seconds to hit the ground
