Answer:
x=0 x = 3/4
Step-by-step explanation:
32x^2 – 24x = 0
Factor out 8x
8x(4x -3)
Using the zero product property
8x = 0 4x-3 =0
x=0 4x=3
x=0 x = 3/4
Answer:
Percent of decrease in the value is 40%.
Step-by-step explanation:
Let's find the value of y when t=1 and t=2 because need to find the decrease by percent of t increases by 1 unit.
When t=1
y=
=0.6
When t=2
y=
=0.36
Percent of decrease = 100 % -
% = 100% -60% =40%
Answer:
3 km per hour
Step-by-step explanation:
You can deduct the answer instinctively since both the distance and the time of the descent are expressed in /5... so you can just get rid of the '/5' in both instances to get the result: 3 kilometers in 1 hour.
But you can also find it easily using the cross-multiplication system:

Then you multiply each side by 5 to get
3 km = 1 hour
Thus the rate of descent is of 3 km per hour.
