Answer:
Step-by-step explanation:
The slope of line u is 9/2; the line perpendicular to that is the opposite reciprocal...opposite sign and the flip of the fraction. The perpendicular slope is -2/9
the domain is all the real numbers, or (-infinite <x<infinite)
the range is y>=-4
axis of symetry is x= -1
vertex is (-1,-4)
the parabola opens upwards
x intercepts (-3,0) and (1,0)
y intercepts (0,-3)
Y-65=3(x-49) 3 is time 49 is crushed
Answer:
Step-by-step explanation:
Let's find the volume of the room in ft³ and that will give
14×22×9=2772ft³
There are deductions. Hence we subtract them from this value
3×5=15, but there are two, hence 15×2=30ft²
And 4×7=28ft²
Hence 2772-(30+28)=2714
Dividing this value by 320 gives
8.4(to 2s.f)
