Well it depends on the function
Answer:
k = 9.
Step-by-step explanation:
2x + 3y -8=0
3y = -2x + 8
y = -2/3 x + 8/3
So the slope of this line is -2/3.
Therefore the slope of a line perpendicular to the above is -1 /-2/3
= 3/2.
kx - 6y = 9
6y = kx - 9
y = k/6x - 3/2
But the slope is 3/2,
So k/6 = 3/2
2k = 18
k = 9.
Answer:
surface area =
Step-by-step explanation:
the given figure is a cuboid,
surface area = 2 ( lb + bh + lh )
( where l is length, b is breadth and h is height )
so,
- area = 2 ( 16×9 + 9×4 + 16×4 )
- area = 2 ( 144 + 36 + 64 )
- area = 2 ( 244 )
- area = 488
so surface area = 488 cm^2
Answer:-496
Step-by-step explanation:
5+69+10−6+29−73−518−12
=74+10−6+29−73−518−12
=84−6+29−73−518−12
=78+29−73−518−12
=107−73−518−12
