1 hour each day is used for test
so 8-1=7 used per day
so commercial is 1 in the 4:2:1 so
4+2+1=7
ok, so 7 units, 7 hours
4 hour for private
2 hour for research
1 hour of commerical
4*5=20=private
2*15=30=research
1*4=40=commercial
20+30+40=90
percent from commercial
40/90=0.44444444444≈44.44% about 44%

Answer: the first one
Step-by-step explanation:
(x,y)->(4x, 4y)
Answer:
Option C is the correct answer.
Step-by-step explanation:
We are given,
<em>A graph where the function first increases and then decreases to touch the x-axis and the increases.</em>
It is required to find the corresponding situations.
So, from the options we have that,
The graph represents the speed of a vehicle which first increases (as it accelerates), then decreases (slows down) and then touch the x-axis (stops at the light) and then increases (accelerates on the ramp for a freeway).
Hence, option C is scenario that the graph describes.
C = b - a
explanation:
you just need to subtract a in this equation.
