It is an empty set because as you may have noticed, these lines have the same slope which means that they are parallel lines and parallel lines never intersect (which means it doesn't have a solution set).
60 divided by 5,
is 12.
In which case,
12 times 3...
Is 36$.
So Leo would pay 36$ for 3 DVDs at the rate of 12$ for each DVD
Hi, It is well simples:
The distance between two points is :
d( A, B) = √[ (xb - xa)^2+(yb - ya)^2+(zb - za)^2]
Then,
A = (xa, ya, za )
B = (xb , yb , zb)
We know:
A = ( 2 ,0 ,-2)
And,
B = (5 , -4 , 6)
___________
xb - xa = 5-2 <=> 3
yb - ya = -4 - 0 <=> -4
zb - za = 6 - (-2) <=> 8
Then us stay:
d( A, B) = √[ (3)^2 + (-4)^2+(8)^2]
= √( 9 + 16 + 64)
= √( 25 + 64)
= √(89)
Answer:
3660ft^3
Step-by-step explanation:
4ft x 30ft x 15ft = 1800ft^3
(12ft - 4ft)(30ft - 7ft - 8ft)(15ft) / 2 = 900ft^3
(12ft - 4ft) x 8ft x 15ft = 960ft^3
1800ft^3 + 900ft^3 + 960ft^3 = 3660ft^3
