Answer:
The correct equation is "y=4x+3"
Step-by-step explanation:
Given equation:

As per the given line formula:

The slope(m) of the line is
and y-intercept at 3, that is the point (c). So, the correct equation of the line:

I got 5. If you divide 210 by 3, you get 40 miles an hour. You then divide 200(miles) by 40(how fast your going) to get 5.

Step by step explanation
Answer:
W = 21.44*10⁶J
Step-by-step explanation:
Given
y = x² (0 < x < 4)
γ = 10000 N/m³
W = ?
If we apply
y = 4² = 16 = h
y = x² ⇒ x = √y
then
V = π*(√y)²*dy = π*y*dy
W = (γ*V) *(16-y) = γ*π*y*dy*(16-y)
⇒ W = γ*π*∫y*(16-y)dy = γ*π*(8y²-(y³/3))
finally we obtain (0 < y < 16)
W = γ*π*(8y²-(y³/3)) = 10000*π*(8*16²-(16³/3)) = 21.44*10⁶J
