Answer:
c
Step-by-step explanation:
The answer to this question is:
While
playing mini golf, you hit the ball off of a wall to attempt at making
it in the hole. The ball is located at (5,4) and the hole is located at
(9,8). The point where the ball hits the wall is (7,0). Write an
equation for the path of the ball and then determine if you will make
your putt.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Step 1:
Hit=9,8
Ball=5,4
R=7,0(This will be the hit point)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Step 2:
(Ball)B'=7+(7-5)4=(9,4)
BR: y-4=(0-4)/(7-5)(x-5)→→→→→→→→→→→→y=-2x+14
RB': y-4=(4-0)/(9-7)(x-9)→→→→→→→→→→→→y=2x-14
Answer:
23.4 km
Step-by-step explanation:
We can use a ratio to solve
13 km x km
-------- = ---------------
5 hours 9 hours
Using cross products
13*9 = 5x
117 = 5x
Divide each side by 5
117/5 = 5x/5
23.4 =x
