3 because the root of 36 is 6 and the root of 225 is 15. Hope this clarifies. For 2, the root of 25 is 5, but 50 is not a perfect square.

Find the equation of the tangent line at the point (1, 6). for y = 4 + 4x2 - 2x3.
Lostsunrise [7]
y = 4 + 4 x^{2}-2x^{3}  Lets \ write \ it \ y = -2 x^{3} +4 x^{2} +4

The tangential line at a certain point is just the derivative so.
y ' = -6 x^{2} +8x. At the point (1,6) we plug the x value in and get the slope at the point (y ' = 2)

The tangential line at that point is
y - 6 = 2(x - 1)     (this is the answer)

Find the surface area of the composite figure
Maslowich

Answer:

498

Step-by-step explanation:

For the blue block: 4(7x2) + 2(2x2) = 56 + 8 = 64

For green block: 4(12x7) + 2(7x7) = 336 +98 = 434
