Answer: x < 5
Step-by-step explanation:
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%
We use sin in vector product and not using cosine because
Sin function is natural for physical process,
The value arise from zero to max
Hope this helps
Recall that the equation of a line passing through two points (x1, y1 and (x2, y2) is given by the formula (y - y1) / (x - x1) = (y2 - y1) / (x2 - x1).
Given that the line passes through the points (-4, 10) and (-1, 5), the equation of the line is given by (y - 10) / (x - (-4)) = (5 - 10) / (-1 - (-4)) = -5 / 3
3(y - 10) = -5(x + 4)
3y - 30 = -5x - 20
<span>3y = -5x + 10
5x + 3y = 10
y = -5/3 x + 10/3</span>
