Lubov Fominskaja [6]

Answer:

9x^4=6,561x

6x^2=36x

6561x+36x=6597x

Step-by-step explanation:

9x to the 4th power is just 9x9=81x9 and so on and the same goes for 6 then you just add them. Not Sure if this is the way you needed but feel free to ask anything.

Mumz [18]

Answer:

Given that a beetle has the pattern, 0.098 is the probability that it belongs to the rare subspecies

Step-by-step explanation:

Probability of having a pattern in rare subspecies = 0.98\\

Percentage of rare subspecies = 1 % = 0.01

Probability of a beetle with pattern belonging to rare subspecies is

=0.01 * 0.98 \\= 0.098

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)
