<span>The line with m=2 @ x=3
y-y1=2(x-3)
You need to find y1.
because 2 line intersecting @ x=3 , y coordinate is the same as well.
Let's find it:
y=2/3 *3 -2=0
So point of intersection is: (3,0)
The equation of the desired line will be:
y-0=2(x-3)
y=2x-6</span>
The answer is 172.8 g.
The volume of the cube (V) is:
V = a³ (a - the side of the cube)
The density (D) <span>is quotient of mass (m) and volume (V):
D = m/V = m/a</span>³
⇒ m = D · a³
<span>
It is given:
D = 2.7 g/cm</span>³
a = 4 cm
Therefore:
m = D · a³ = 2.7 · 4³ = 172.8 g
Answer:
EG = 28
Step-by-step explanation:
EH is the same as HG.
EG and HG are each half of EG.
EG = HG + EH
EG = 14 + 14
EG = 28
The correct answer is 14/9
